Blast Chillers

Blast chillers drop food temperatures from 160 degrees F to 35 degrees F in 4 hours or quicker.


Blast Chiller Cleaning and Maintenance

With blast chillers, proper temperatures can mean the difference between maintaining food quality during cooling and potentially creating an unsafe environment that breeds bacteria. Proper blast chiller maintenance is important from a safety standpoint since temperature consistency is key for HACCP reporting.

The average service life of a blast chiller can vary, depending on use, environment and manufacturer but most last between 5 and 10 years. Operators can take a number of steps to prolong the service life of these units and keep systems in safe operating condition.

Unlike refrigeration equipment, blast chillers are not designed for continuous operation and should be shut off when not in use.

The maintenance requirements of blast chillers are similar to other refrigeration equipment. Condenser coils need to be kept clean, not only to ensure the unit chills properly but also for optimal energy efficiency. This component should be cleaned every 30 days, using non-metal brushes to remove all dust and dirt from the condenser blades. There should be as much airflow as possible. 

Blast chiller probes should be kept clean of food product. Door gaskets should be kept clean by washing with water and wiping down with a dry cloth 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.

Keep drain lines clean of condensate water to prevent backups.

When service calls become more frequent and repair costs start adding up, especially with an older blast chiller or a unit that has experienced heavy use, it is probably time to consider a new system.

If the blast chiller seems to have hit maximum capacity or is running 24/7, it may be time to replace it with a larger model.
