Maintaining blast chillers is important from a safety standpoint, since temperature consistency is key for Hazard Analysis and Critical Control Points (HACCP) reporting. Operators can take a number of steps to prolong the service life of these units and keep systems in safe operating condition.
- Condenser coils need to be kept clean, not only to ensure the unit chills properly but also for optimal energy efficiency. There should be as much airflow as possible.
- Blast chiller probes should be kept clean of food product.
- Door gaskets should be kept clean in order to provide a tight seal. If warm air and moisture get inside the blast chiller, the unit will need to work harder to maintain proper temperatures.
- The unit's interior and exterior should be kept clean and wiped down with mild soap and water after use.
- If drain lines are utilized, these should be kept clean of condensate water to prevent backups.
