When you walk into a giant freezer or merely use the one above your refrigerator, do you ever stop and wonder about the process that goes into keeping your items cool? Of course not unless you are like us, and intimately close to the entire process. Here at C&M Coolroom Services, we fully believe in the power of knowledge and what it can to for our potential customers. With that mindset, we are going to take a moment to peak all-the-way inside of our refrigerating units in order to discuss the refrigerants that make the process possible. Specifically, our discussion today will be focused on how CFC-free refrigerants can benefit you, us, and the world around us.

Refrigerants: What Are They And Why CFC-Free Is the Way to Go?

We are going to open up our discussion by analysing the core subject: refrigerants. Most people know only that their freezers and refrigerators function, and that is enough for them. However, their luxurious appliances would not be able to function without the use of refrigerant!

1. What Is Refrigerant? – Refrigerant is a substance, typically liquid, which helps to cool down your appliance. These liquids undergo a transformation from liquid to gas and back again in order to accomplish this task.

When discussing refrigerants, people within the industry will be quick to point out one of the most problematic materials involved: CFC. CFC refrigerants became incredibly commonplace throughout the world starting back in the early 20th Century. However, despite their commonplace use, there was a larger problem at hand. Extensive research has revealed that CFC refrigerant is a chemical that should no longer be used. Why is that?

2. CFC Refrigerant – Despite being low in toxicity in relation to our breathing, CFC refrigerant is immensely damaging to the environment. CFC damages the Ozone layer and contributes directly to the destruction of our environment!

Benefits of CFC-Free Refrigerant

Understanding that CFC refrigerant is bad for our world will allow you to understand why the chemical has been phased out of every major industry. We no longer use CFC refrigerant and are now focused on more environmentally friendly and economically beneficial refrigerant compounds. What you’ll find in most modern appliances is something called HFC, or HydroFluoroCarbon. What is HFC? We’re glad that you asked!

3. Benefits Of HFC Refrigerant – HFC is free of chlorine, the chemical that causes damage to our Ozone layer. HFC can be found in products all around the world and it is the only chemical being used on new, legal, productions.

If you want to add affordable and environmentally friendly freezers to your business, you’ve come to the right place. Here at C& M Coolroom Services, we are ready to be of service to you.

To say that your freezer or coolroom is an important part of your business would be an understatement. Having a proper location to store all of your foods or products that require extensive temperature cool is an integral factor for people in a variety of different industries. Coolrooms and freezers are employed in everything from medicine to food storage, and all of the different categories in between. Temperature control in these situations is a requirement and that means that special attention must be paid to the quality of door seals for the cooling and freezing facilities. When a door seal fails, you lose control of the quality of your room. With that introduction out of the way, what are the causes of cracks and breaks in your coolroom or freezer seals?

Breaks & Cracks in Door Seals for Coolrooms and Freezers

No matter how big or small your coolroom or freezer actually is, the utility can only be effective if the door is properly sealed. Consider running your air conditioner at home, don’t you make sure to close all of the doors and windows? The reason is obvious: you want a seal that keeps the cool air in, thus allowing you to control the temperature of the location. However, when your seals begin to break down, you end up losing control. What causes these cracks and breakages in your freezer seals and coolroom seals?

1) Temperature Changes – Rubber seals will all react differently to prolonged exposure to extreme temperatures, such as the temperature of a freezer. Over time, these extreme temperatures can cause minor fracturing to occur then leads to larger cracks forming. The cracks will be further exacerbated by the extreme temperature and your cooling unit will have to work overtime in order to compensate, thus creating more issues.

2) Wear and Tear – When the integrity of your door seal is compromised by physical trauma, such as the routine wear and tear from opening and closing the door, problems can start to crop up. In such extreme temperatures, even a slight crack can begin to grow. Small cracks tend to prevent the elastomer from maintaining its elasticity, thus causing further problems down the line.

Modular coolrooms and freezers components are made by different manufacturers. Like some three-dimensional puzzle, the parts assemble to form an impressive walk-in refrigeration system. Think for a moment, though. If substandard parts are purchased, then a substandard coolroom is what you’ll have at day’s end. By always sourcing quality parts, C&M Coolroom Services sidestep such unconscionable blunders. Even sealant selection procedures bow to this nuanced parts selection approach.

Sourcing The Coolroom Components

In olden days, knights worried about chinks in their armour. Well, that concern still exists today, but it’s more of an engineering issue now. Imagine the buyers and fabricators as they clock in for the day at C&M Coolroom Services. A new client is seeking an affordable refrigeration unit, one that’s budget-friendly yet reliable. The best approach here is to begin all the way back, right at the purchasing phase of the project. After all, for every perfectly insulated aluminium-bonded panel, there should also be a quality silicone sealant and fastener to thermally bind those segments together.

Let’s Establish Benchmarks

Back at the fictional workshop of the substandard business operation, moderately effective parts are coming together. They’re even receiving a carefully applied coating of silicone paste. The metal parts, tacky sealants, and electromechanical parts assemble, but the finished modular system is woefully packed with weak links. Even when the sloppily selected parts work properly, the techs aren’t locking the components together in the right way. Meanwhile, over at the C&M Coolrooms offices, affordable rates are being set. Those rates never compromise the work, never take shortcuts, and they absolutely never allow shoddy work practices.

An Unconstrained Installation Service

Sticking with the refrigeration experts this time, aren’t these technicians more than puzzle solvers? Granted the modular panels, refrigeration unit, and shelving systems all need to be assembled in the right order. However, there’s more going on here. That affordable construct must fit its installation site, and by “fit,” there’s more to the service than simple dimensional measurements. Is the concrete equipped to deal with the cold? If not, it’ll heave and crack. Likewise, the venting, drainage, and electrical power requirements take the technicians beyond the installation envelope.

Without a doubt, affordable coolroom and freezer rates are available at C&M Coolroom Services. The rates allow for cost-estimation and customization but never permit product skimping or inferior parts. From the concrete floor to the panel sealant, from the high-efficiency refrigeration unit to the vents and drains, the final design will satisfy the clients’ system demands. Affordable but never cheap, that’s a mission statement worth endorsing.

 

Coolrooms don’t look all that dangerous. It’s freezing cold in there, especially inside a walk-in freezer, but the chill passes rapidly. The staff member gets in, collects or drops food, and is out again in no time at all. What about worst-case scenarios? They exist. And what about general precautions? They’re needed if the employee is to operate under an appliance-mandated umbrella of safety.

Warehouse Coolroom Safety

Sometimes the work area isn’t confined to a walk-in enclosure. Sometimes the chill is all around you. In some distant industrial complex, it’s a meat processing environment that’s feeling the chill. Plastic curtains are swinging as a ceiling-mounted refrigeration unit roars in the background. In front of the employees, a stainless steel conveyor system is transporting joints of beef. Of some concern, the damp and freezing conditions are hampering productivity. Chilblains, a circulatory problem, are slowing down the work. Another staff member is labouring hard, but his hands are trembling badly. Floor-installed warming plates and radiant heaters protect workers. Reinforce that move by shortening the work shifts. A ten-minute break could make all the difference.

Walk-in Coolroom Protection

Walk-in units carry a unique set of risk factors. What if you’re in there alone? The door is damaged, it hasn’t been reported to maintenance, and now the exit is jammed. As said mentioned earlier, a quick dip inside the frosty chamber won’t cause any problems, but an extended stay definitely will. Avoid this situation by always working with a co-worker. If that rule is broken, then you need to know that you have options. A high-quality door mechanism minimizes such incidents. Furthermore, a panic button, alarm indicator, or intercom, should be in place inside the insulated coolroom. Armed with this precautionary measure, the employee can always call for assistance when the door fails. Even if the door is functioning properly, a patch of ice or some other unforeseen event could render the worker incapable of action. Without a co-worker, an alarm system is an essential measure.

Finally, there are hygiene and technical risk factors. If an electrical system is damaged, perhaps the wires are exposed, then you must never touch those exposed parts. The ice and steel in there could function as a strong grounding path, so an electrical shock could prove fatal. Similarly, patches of mold or bacterial-laced growths are unlikely inside a space that’s designed to arrest biological development. Still, if these growths are detected, report them immediately, fill in an incident report, and wash your hands. Above all else, always dress warmly when working in this setting.

Businesses need to understand the health and safety prerequisites for a coolroom environment, before installing or refurbishing one in their establishment. They need to know that these rooms must stay at the right temperature for the items that will be stored in them. This will influence which type of coolroom that they need to install in their establishment. Also, these businesses need to train their employees of the dangers of these rooms in order to prevent issues and injuries. Refer to the following explanation for further facts about these and other prerequisites.

Install the Right Size of Unit for Your Needs

Select the size of unit that you will need to accommodate your needs in a non-crowded manner. For one thing, this will make it easier to locate the items that you require when the time comes, and for another thing, food or other items will cool in a more thorough manner when they are not all crammed together.

The Coolroom Must Stay at the Correct Temperature to Safeguard the Enclosed Elements

When you choose your coolroom style and size, you need to ensure that it will reach and maintain the correct temperature to keep your items safe and fresh for use. The desirable temperature will be dependent upon the elements that you need to refrigerate in it. After all, many types of businesses require the use of coolrooms and range from food-service ones to wineries and laboratories.

Train Your Employees About Proper Coolroom Operation and Any Risks

You have a responsibility to train your employees of the proper way to operate, maintain and access your coolroom setup. Through this, you will prevent unnecessary issues and even injuries from occurring. Training needs to include all pertinent regulations, and you should do it on an ongoing basis to ensure that new employees receive all of the instructions as well as refresh the memories of the present employees.

Your Coolroom Must Adhere to OH&S Standards

A coolroom of any type must adhere to OH&S standards in order for a business to use it without issues. These standards govern the construction of it along with the range of temperatures that it can reach and maintain. This is especially vital if you are refrigerating food or medical items.

For additional health and safety prerequisites for a coolroom environment, consult with C&M Coolroom Services. We not only install, renovate, repair and maintain quality coolrooms, but we also do the same with controlled environments, blast-freezers and freezers for factories, restaurants, stores, laboratories, supermarkets and food preparations or processing facilities.

Operating a business isn’t easy, especially for all types of restaurants, cafeterias, convenience stores, or other food related establishments, that’s because they rely on the continuous functioning of freezers and coolrooms. When freezers and coolrooms do not function properly because of the effects of bad electrical connection, food related businesses are at great risk of losing business and valuable food stocks.

The effects of bad electrical connection in freezers and coolrooms can literally drain a company of considerable money, and can cause machinery to malfunction or cease to function. This can adversely affect chilled and frozen foods, or cause an exorbitant increase in the amount of energy used. Basically, bad electrical connection in coolrooms and freezers is definitely not good for business.

Particularly, electrical connection problems can even cause the compressor to malfunction or fail, resulting in very expensive losses to products and stored food in freezers and coolrooms. Thankfully, these problems as well as unnecessarily high energy usage from bad electrical connections can be avoided, by taking corrective action as soon as inconsistent temperature and electrical usage are observed.

Avoid Negative Freezer and Coolroom Effects from A Bad Electrical Connection

To avoid excessive energy usage and costly repairs of electrical components, as well as the loss of valuable food stocks, it is advised to have your freezers and coolrooms professionally inspected with diagnostic testing and maintained on a regular basis.

The main effects of bad electrical connection in freezers and coolrooms is the lack of temperature consistency. This problem hits restaurants, cafeterias, and convenience stores hard, especially during summer when the temperature is hotter. When freezers and coolrooms have inconsistent temperatures, food stocks will spoil faster, and businesses have to absorb the costs of spoiled products and high energy costs caused ultimately by a bad electrical connection.

Monitoring the digital thermostat and then recording it daily will help to ascertain if there may be a bad electrical connection. While a few degrees of thermal variance is within the norm of a busy restaurant’s coolroom, any major fluctuations can be a tell-tale sign there is an electrical problem. Another indication would be if a noticeable influx of electrical usage is discovered or a trip circuit breaker.

Because freezers and coolrooms are designed specially to meet exact engineering standards, they rarely do break down. However, when there is a problem, it can often be electrical in nature, especially if there is a blown fuse or tripped circuit breaker.

A broken freezer gasket is allowing warm air into a hard-working freezer. The compressor unit responds to the leak by working harder. It’s going to wear out soon unless the broken seal is replaced. Continuously operating compressors, pools of water, spoiled food, and increasing operational costs, all of these problems can be explained by calling out a service engineer, someone who’ll likely go straight to that broken gasket.

Coping with Counterintuitive Effects

If warm air is getting inside the freezer, why is the refrigeration unit gaining a layer of ice? Speaking plainly, the equipment is doing too much. It’s running continuously because the sealed enclosure is starting to warm. It’s a hopeless battle, this accelerated refrigeration cycle, for more warm air replaces the now cool air, and so on. If the gasket damage is bad enough, the refrigeration equipment is going to fail. However, a sort of balance can be achieved. The warm air is still there, but the overburdened cooling gear is keeping the freezer at the desired temperature, as set by the thermostat. However, the loser in this battle is always the equipment coils, for coils ice-up when gasket damage remains undiscovered.

Loss of a Food-Safe Environment

Even if the low temperature overwhelms the leaking air, the thermal envelope is now compromised. Temperature fluctuations will take place over the course of a day, the food will defrost partially then freeze again. That’s not an acceptable situation. For starters, the food will spoil and lose its fresh taste. Worse yet, the bacteria inside the food will be stimulated. Bacteria grows when subzero conditions aren’t properly regulated. Strange odours propagate due to the rising mercury. Water is dripping, a patch of ugly mould is forming on the ceiling, and the broken gasket is still concealing its wound. Even the kitchen owner is feeling the bite, but he hasn’t gone near the freezer for weeks. In this unfortunate case, the operational bills are going through the roof. Bills of fresh currency may as well be pouring through the gasket, for that’s where the energy is being lost.

Lost cooling potency triggers a battling compressor unit. Ironically, the toiling equipment only worsens the problem. After all, extra electricity consumption equals a larger energy bill, something a catering establishment loathes, and with good reason. However, the worst is yet to come. The dripping water is feeding mould, and the pooled liquid slippery, which means a possible industrial accident is imminent. Meanwhile, the poorly regulated temperature is producing spoiled food and a potential health hazard. Identify, address, and repair that broken gasket quickly.

 

For a safe and segregated work environment, it’s important to have a series of PVC strip doors that perform exactly as intended. In specially controlled coolrooms and freezers, that degree of performance proficiency assumes a critically important role, for the cold zones in here cannot be impacted by an exterior heat source. In light of this very real process-endangering threat, flexible plastic screen maintenance is a high-priority service.

Damaged PVC Strip Doors Corrupt Coolrooms 

Picture a high-traffic area, a shielded threshold that uses one of these economic barriers. Manually operated pallet stackers push past the suspended plastic strips all day long. Then, with a blare of a warning klaxon, a forklift truck presses through the barrier. The PVC is abrasion resistant and determined to hold the line, but let’s face it, even the toughest plastics can’t last forever, not when they’re under attack like this. A strip breaks or drops loose from its overhead mount. Suddenly, the coolroom environment is compromised. A breeze pulls in a cloud of airborne dirt. The food-safe zone is exposed. Next, the cold temperature level is warming. The thermal envelope has been disturbed by the PVC strip curtain’s breach.

Assessing the Damage 

Even the refrigeration unit is feeling a knock-on effect. The frosty environment is harder to sustain, so the cooling appliance is working harder. That means poorly maintained PVC strip doors cost businesses money. The utility bill is increasing because the cold zone lacks important insulation. In point of fact, the plastic barrier could be between an inside storage area and an outside loading pier, so this temperature differential might worsen as the day warms. Finally, the PVC does stop temperature leakages and keep cold zones intact. It also stops cross-contamination and floating particulates from hurting hygiene-sensitive work areas. But these fittings also act as workflow facilitators. In short, there are no lengthy pauses to roll up a heavy door, so there are no operational hindrances affecting the business runnings. However, should the PVC material accumulate enough scratches, it will no longer function as a safe secondary doorway. Visibility problems cause accidents, especially when there are forklift trucks roaming the area.

Maintain PVC strip doors and keep this visibility factor intact. Maintain the plastic curtains so that they overlap fully and preserve the cold environment inside cold work zones. Importantly, when this key secondary threshold is properly cared for, large-scale coolrooms and freezers sustain their low-temperature environments. When that chill is maintained, noise levels are controlled, utility bills drop, and the frosty status quo keeps right on going.

Temperature consistency is a factor that safely preserves the contents of a sterile environment. Think about a laboratory, a clinical domain. There are tissue samples stored in here, plus shelves of bacterial cultures. Every variable is controlled in here. Thanks to that carefully regulated laboratory setting, the biological samples behave in a predictable manner. Now, however, the lab freezer is breaking down. Temperature consistency has gone out the window.

Introducing Experimental Bias 

The experiment is a bust. Those monitored results are meaningless because the intended thermal envelope became biased. That lab freezer or cooling chamber, designed to absolutely maintain a set temperature level, is no longer capable of producing a baseline artificial climate, one that acts as an experiment benchmark. Imagine a research project that’s recording this prejudiced data. In no uncertain terms, that experiment has gone awry because the sterile environment lacked an objective focal point. Uncontaminated by outside factors, the scientifically accurate device was still impacted by the poorly regulated temperature.

The Importance of Temperature Consistency 

This problem hits medical facilities hard. When flu season hits, there are vaccines ready to mitigate the spread. What if the coolroom containing the vaccine phials experiences a temperature spike? The thermal transient either disables the potent curative or entirely neutralizes the stuff. A large pharmaceuticals establishment might absorb this costly mistake, but a small clinic could be ruined by this catastrophic incident. Besides the cost to the clinic, there’s the fact that there’s going to be a shortage of booster shots. Lives rely on those shots. Hospital labs or vaccine production facilities, the impact of a failing lab freezer, one that employs a sterile environment, will likely be felt keenly.

Determining Remedial Actions 

First off, intelligently monitored freezers and coolrooms in laboratory situations must be calibrated. Obviously, the digital thermostat has to work as it’s supposed to, but that degree of functionality isn’t enough. Granted, in a food-based operation, a couple of degrees of thermal variance might be acceptable, but even a single whole degree of miscalibrated warmth could ruin the biological samples we’ve described today. No, not only must the device work as designed, it must be meticulously calibrated so that it provides a reliable thermal baseline.

Lives are lost when clinically accurate freezers and coolrooms don’t do their job. The environment inside these carefully monitored enclosures may indeed be sterile, but that key control element doesn’t mean much if the temperature envelope in here is in error. Have the device calibrated by a lab-compliant instrumentation correction lab, a place that adheres to the NIST (National Institute of Standards and Technology) guidelines. Fortify that action by setting all temperature alarms and obeying all good storage practices.

A kitchen staff member has just reported a dripping freezer. The unit in question is creating a small pool on the floor. There’s no way that freezer is reaching the right temperature. Alarm bells go off in the kitchen manager’s head. If the equipment isn’t keeping its contents frozen, a dangerous hygiene jeopardizing incident could be brewing. Quick, time is of the essence, what’s causing the warming effect?

A Damaged Thermostat 

Check the obvious causal factors before calling out an engineer. But be quick about it, this issue can’t be allowed to continue. Is the thermostat set at the right temperature? In degrees Celsius, we’re looking for a digital readout that sinks below 0°C. That’s 32°F for those who use the Fahrenheit scale. Use a mental checklist to explore all possible options. If the power has been knocked out, reset the circuit breaker. If it trips again, the problem is electrical, so call the engineer.

Seek Out Insulation Trouble 

This next problem requires sleuthing skill. If the door seal is damaged, the freezer can’t maintain its cooling envelope. By the way, this particular defect could be causing the circuit breaker problems. After all, the appliance compressor works harder when the enclosure warms. As that electrical unit labours ever harder, more electrical power is consumed. The result of this off-kilter battle is either a high power bill or a damaged compressor. Again, if that circuit breaker is tripping, call in an engineer. By chance, has a staff member been leaving the freezer door open? Sometimes the simplest solution is to ask around for more information.

Cracking the Mechanical Issues 

Dirty condenser coils are next. The heat exchange process works splendidly when the appliance coils are clean, but a thick layer of grime saps performance. It may involve a little acrobatics, but can someone see the dirt on the coils. Are there cobwebs and filth on the underside of the compressor unit? If there is, that’s another hygiene blunder, an oversight that must be immediately addressed. Alternatively, a low refrigerant charge means there’s insufficient chemical power in the system. The only recourse, once more, is to call in a local refrigeration engineer.

Freezer dripping incidents cause much consternation. Is the fluid water? It probably is melted ice, but it could also be freon. Refrigerant chemicals can damage the environment, so shut everything down. The cooling unit is also running continuously, but the temperature isn’t dropping, so that refrigerant level has definitely dropped. However, if the dripping liquid is water, try those common-sense solutions first. If they don’t yield results, the chamber insulation or electrical circuitry likely requires professional attention.

Cables carry electricity. If they’re not conducting power, they’re supporting a load or retaining something. Just to mix things up a little, FLX self-regulating heater cables shy away from both of these applications. As the title implies, this type of stranded wiring is designed to emit thermal energy, which makes the product an ideal match for the coolroom industry. That being said, how do these self-regulating strands work?

An introduction to Basic Electrical Principles 

What if we designed a circuit that was built to make heat? Well, it turns out this electrical part has been around for a long time. Look at the electrical elements on a common cooker. These are resistive wires. Coated with a copper sheath and a fine layer of magnesium oxide powder, coiled electrical elements glow red hot when they cook and boil things. An FLX self-regulating cable uses this same principle, but the emitted heat is meant only for freeze protection, not cooking.

Designing A Freeze Protection Solution 

A cable coils around a pipe. It’s hooked into the power supply, but the current flowing in the line is slight. Used in a walk-in freezer, the resistive energy produces a slender 10°C heat envelope around the strands, so all nearby contact surfaces retain an above zero temperature level. Remember, the sudden entrance of warm outdoor air, perhaps due to a door opening, tends to cause icy sticking. The air melts the ice, it hardens when the door closes, and it refuses to open the next time someone needs entrance into the freezer. By mounting FLX self-regulating cabling around the door frame, this ice sticking problem is solved.

Where’s Does The Self-Regulating Feature Enter? 

Electrical principles regulate the wire. Inside that wire, twin cables are separated by a special plastic core. If the ambient temperature drops, the special plastic conducts more efficiently. Then, if the outside temperature rises, the plastic becomes an insulator. It’s a clever trick, one that ensures this heating cable can control its output without requiring the services of a bulky circuit thermostat.

Five layers of self-regulating wires and insulation shape FLX heating cables. An outer layer of plastic covers a metal braid. Under that woven copper, there’s another jacket of plastic insulation. Below these flexible layers, the real heating magic exists. It’s in here that the insulating plastic core and twin rail wires produce just enough self-regulating heat to stop a freezer door from jamming. Used in pipes, underfloor conduits, and more, this self-limiting feature makes the simple cabling a desirable freeze protection accessory.

An arctic chill sends the mercury level on a wall-mounted thermostat plummeting. The perishable contents inside the insulated storage unit freeze. This is a blast freezer, an environment that’s ruled by frigid power. In here, banks of fans force icy air across the food. Flash frozen in an instant, the cooling system does consume more energy than a conventional freezer, so what benefits offset this extra power expenditure?

Supports Cellular Preservation 

Imagine a plate full of raspberries. Cooled inside a regular freezer, the water stored inside this succulent fruit expands. It turns to ice. The cell membranes of each juicy raspberry end up as a mushy mess because of that cell rupturing effect. Blast freezers cool water-loaded foods so fast, there’s no way this cellular damage can take place.

Flavour and Texture Preservation 

This next benefit follows directly on from our initial conclusion. Basically, the flash frozen cells remain undamaged, so the food’s texture is retained. Meaty soft tissues cook as intended when this key feature is realized. Likewise, the nutrients stored in the meat, vegetables, and fruit are preserved. Finally, and perhaps best of all, the food tastes better. Those preserved nutrients are plainly translated into a finer eating experience.

Acts as a Powerful Bacterial Exterminator 

Regular freezers do slow the growth of these microorganisms, and they may even send the bacteria to sleep. A shock freezer, which is another name for this rapid freezing equipment, eliminates all but the most stubborn bacteria. The tiny organisms can’t stand the extreme cold, nor can they metabolize when they’re deprived of liquid water. Shock freezers enhance food-hygienic cooling environments.

Designed to Create Specialized Commodities 

Classed as a time-sensitive freezing process, shock cooling is also employed in many other food-based instances. Ice cream makers rely on the production of tiny ice crystals when the fan-powered cooling effect sends the temperature tumbling. TV dinners also take advantage of this fast production feature. The cellophane-packed meals slide past the chiller units on a production line, only to exit seconds later as a packaged item, ready for the supermarket cooler.

Instead of large, cell-rupturing ice crystals, blast freezers create small packets of finely chilled water. Those smaller ice particles assure taste and texture preservation. Furthermore, this rapid cooling process is designed to kill bacteria, so the equipment has an inbuilt food purifying feature. Finally, blast freezers are designed to operate on production lines. They flash preserve TV dinners, ice cream, seafood, and other perishable commodities so that they can be delivered to market in a timely manner.
