During long-term operation, milk pasteurization tanks are subjected to various factors such as heating, agitation, cleaning, and material corrosion. Proper daily maintenance not only ensures the equipment remains in good working condition but also minimizes unexpected breakdowns and downtime.

First, temperature sensors should be inspected regularly. Temperature control in the pasteurization tank relies on accurate temperature sensing; if a sensor drifts, the actual product temperature may differ from the displayed reading. Therefore, inspections and calibrations must be performed in accordance with the company's equipment management protocols.

Second, attention must be paid to the agitation system. Check the motor, gearbox, agitator shaft, and mechanical seal for abnormal noise, vibration, or leakage. If any operational anomalies are detected, the equipment should be shut down immediately for inspection to prevent minor issues from escalating.

The jacket and piping are also key areas for daily maintenance. Inspect steam, hot water, or cooling medium lines for leaks, and check the condition of associated valves, connections, and seals.

The equipment should be cleaned promptly after use to prevent milk residue from adhering to the inner tank walls for extended periods. For equipment utilizing CIP (Clean-in-Place) systems, regularly verify the proper functioning of spray devices, piping, and valves.

Additionally, the inner tank surfaces and weld seams should be inspected periodically. Any significant scratches, corrosion, or abnormalities must be addressed promptly. Maintaining the integrity and cleanliness of product-contact surfaces is crucial for food production equipment.

Regarding the electrical system, inspect the control cabinet, wiring, push-buttons, and relevant protective devices. For highly automated pasteurization tanks, control programs and process parameters should also be backed up and checked regularly.

In summary, the maintenance of milk pasteurization tanks should adhere to the principles of regular inspection, timely cleaning, standardized operation, and prompt resolution of issues. Maintaining equipment maintenance records helps the enterprise monitor the equipment's operational status and effectively schedule preventive maintenance.
