How Freezer and Coolroom Audit Can Help Control Harmful Microorganisms
08 November 2017A professionally conducted energy audit determines whether your commercial freezer really is as indestructible as it looks. Tasked with analyzing the energy envelope inside these insulated enclosures, the tests track waste energy, monitor losses over time, and even identify the reasons for the thermal shortfall. Furthermore, a properly identified energy consumption profile helps govern certain system management factors. For example, harmful organisms can’t exist when freezer and coolroom audits rule supreme.
Reviewing Coolroom Energy Audits
If it helps, picture a traditionally maintained walk-in unit as a two-dimensional auditing system. A couple of thermometers take care of this job. The appliance caretaker places one temperature measuring device in a suspected warm spot, then he places the next one at a known chill zone, perhaps right below the refrigeration unit. Measured via a differential calculation, the energy losses are found. But this is something of an approximation, not a scientifically conducted procedure. True energy audits use time-based temperature monitors, devices that compile a three-dimensional model so that a fully illustrated energy profile is produced. That energy envelope accounts for foot traffic, refrigeration output energy, and wall insulation issues, among many other factors.
Controlling Harmful Organisms
If that audit is conducted diligently, then every conceivable operational factor becomes part of the energy profile. Is the food being handled properly? That factor is established and recorded in the report. That compiled assessment also notes any cross-contamination problems, marks insulation seal damage, and clearly shows the spots where the chamber is experiencing major structural issues. Furthermore, unsanitary pools of water and questionable growths are labelled as actionable trouble sites, places where mildew or mold are beginning their spread. That audit, as it figuratively scours its way through your freezer and coolroom, is sure to uncover hidden growths. As for the immediately obvious patches, the sites where harmful organisms are taking hold, these are quickly recognized when a comprehensively run audit is executed correctly.
Think of freezer and coolroom audits as a weapon in a two-pronged attack. The second part of this food safety program is a maintenance plan. The audit swings into action when system energy ratings incur hefty energy losses. Meanwhile, the maintenance program prevents problems before they occur. Working together, the two techniques stop bacterial growths. As for the audit, this tool looks deeper than a standard maintenance strategy, so deep that it sees exactly where the cross-contamination problems and foot traffic puddles are occurring. Identified in no time at all, the assessment report will also suggest a sanitary solution, one that does away with the harmful organisms before they can impact the stored food.
