5. Operating Instructions

The Happybuy ZD-50L features a user-friendly control panel for precise operation.

1. Fill the Tank: Open the lid and carefully pour the liquid to be pasteurized into the stainless steel tank. Do not exceed the maximum fill line indicated by the water level tube.
2. Close the Lid: Securely close the lid to maintain temperature and prevent contamination.
3. Power On: Turn on the main power switch. The control panel display will illuminate.
4. Set Temperature: Use the temperature adjustment buttons on the control panel to set the desired pasteurization temperature. Common pasteurization temperatures for milk range from 63°C (145°F) for 30 minutes (batch pasteurization) to 72°C (161°F) for 15 seconds (HTST, though this unit is typically for batch). Consult local food safety guidelines for specific requirements.

6. Start Heating: Press the 'Heat' button to begin the heating process. The unit will automatically heat the liquid to the set temperature. The display will show the current temperature.
7. Mixing (Optional): If your model includes a mixing function, activate it to ensure even heat distribution throughout the liquid.
8. Holding Phase: Once the target temperature is reached, the unit will maintain this temperature for the set duration.
9. Cooling: After the holding time is complete, the unit will initiate a cooling phase. The cooling time can also be adjusted.
10. Draining: Once the pasteurization and cooling cycles are complete, open the butterfly valve to drain the pasteurized liquid into a clean, sanitized container.
11. Power Off: Turn off the main power switch and disconnect the unit from the power supply after use.

6. Maintenance

Regular cleaning and maintenance are crucial for the longevity and hygienic operation of your pasteurizer.

1. Daily Cleaning: After each use, immediately drain any remaining liquid. Rinse the interior of the tank with warm water. Use a soft brush or sponge with a mild, food-safe detergent to clean all internal surfaces, the lid, and the butterfly valve. Rinse thoroughly with clean water until all detergent residue is removed.
2. Sanitization: After cleaning, it is recommended to sanitize all food-contact surfaces according to local food safety regulations. This typically involves using a food-grade sanitizer solution.
3. Exterior Cleaning: Wipe down the exterior of the unit with a damp cloth. Do not use abrasive cleaners or immerse the control panel.
4. Component Inspection: Regularly inspect gaskets, the heating rod, and the butterfly valve for wear or damage. Replace any worn components promptly to ensure proper sealing and operation. The unit's components are designed to be easily detachable and replaceable.
