Maintenance of direct cooling milk tanks

To maintain milk tank equipment effectively, it is crucial to assign a dedicated person to oversee its operation. Operators must closely monitor the refrigeration system, maintain detailed operation records, and address any abnormalities promptly.

Key maintenance steps include:

1. **Monthly Leak Checks**: Use a chlorinated lamp to inspect the refrigeration system for leaks. If issues are detected, conduct a comprehensive inspection and add Freon if necessary.

2. **Annual Filter Maintenance**: Clean or replace the desiccant filter and ensure the desiccant is thoroughly dried.

3. **System Checks**: Verify the operation of high and low-pressure controllers, inspect pressure indicators for fluctuations, and check for rust or damage in control tank components.

4. **Temperature Controller Inspection**: Ensure the digital temperature controller is functioning correctly.

5. **Tank Interior Inspection**: Look for pitting or damage inside the tank.

6. **Agitator Maintenance**: Check for oil shortages and ensure the oil seal is intact.

7. **Extended Downtime Care**: If the unit is not in use for an extended period, recover Freon into the reservoir and close the inlet and outlet valves. During winter, drain water from the condenser coil to prevent freezing and cracking.

Adhering to these practices ensures the milk tank remains in optimal condition and extends its service life.
