Coolroom and Freezer Door Functions22 August 2016
Considerable focus is placed on the design of a coolroom, and much of that attention ends up on the interior, for this is where stored commodities receive their temperature controlled airflow. In maintaining the chill within the insulated alcove, the thermal isolating properties of the walls, ceiling, and floors are duly assessed, but what of the primary access point? Coolroom and freezer door functions could certainly be perceived as a chink in the insulating armour here, so those functions need to be evaluated if we’re to guarantee the integrity of this entryway.
Strong rubberized seals and spring-loaded mechanical levers guard the access route when catering personnel hustle into the chilly alcove to pick up foodstuff and prepare a meal, but this contemporary storage outlay is only one of many possible coolroom designs. Modern beverage cabinets represent an example of expanded utilization. In here, the front-facing wall is replaced by numerous glass-paneled doors. A concealed doorway is in the rear of the coolroom, so the attending stockroom worker is always on hand to replenish an empty beverage shelf.
Expanding on Coolroom and Freezer Functions
Compressible rubber seals use wear-resistant polymers to cancel out the abrasive influence of a metal door on a track. Similarly, those larger units are designed from durable alloys, metals that won’t wear or deform when a meat trolley slips down a padded ramp. The build is obviously toughened to avoid contraction events, the curve and deformation effects caused by subzero temperatures, but they’re also imbued with other essential properties, including a low-profile design that bolsters a hygiene-oriented work environment. Fasteners and door controls, seals and sliding tracks, all of these parts are constructed in such a way as to emphasize a sanitary design ethic.
Adopting Electrically-Enhanced Builds
Manually operated door controls are hard to access when a staff member is balancing multiple items of food, wine, or chemicals, so an electrically-actuated mechanism works in tandem with spring-loaded door controls to power admission into the frosty alcove. That same methodology is typically applied to large-scale doors, with electrical heating elements representing the front line of this approach. The heater stops the seal from freezing and cracking. Of course, this self-regulating wire only provides enough energy for these tasks and no more.
In properly establishing coolroom and freezer functions, we’re working within a mechanical framework, an area that must eliminate air infiltration while providing a consistently accessible route to the stockpiled materials stored within the cold alcove.
