Heat preservation method of vertical freezer

Vertical freezer is a common commercial refrigeration equipment, which is suitable for shopping malls, supermarkets, hotels, food processing and other places. Thermal insulation is the basis of normal operation of freezer. Reasonable heat preservation measures can not only reduce energy consumption and prolong cold storage time, but also ensure the quality, hygiene and safety of stored food. The following are the insulation methods for vertical freezers:

1, regular defrosting: too much frost inside the freezer will increase the burden of the freezer and reduce the insulation effect. Therefore, it is very necessary to defrost regularly. It is recommended to defrost regularly at regular intervals. When storing frozen food, you can thicken towels or other insulation materials around the food to reduce temperature loss.

2. Correct loading: Frozen food should be placed on the lower floor of the freezer, and frozen products such as ice cream should be placed on the upper floor. Perishable foods should be avoided to be stored in the freezer for a long time to prevent odor and cross-contamination.

3. Ensure sealing: The sealing performance of the freezer door is very important. Always check whether the door sealing ring is complete and damaged. If the door is not tightly sealed, it will lead to temperature leakage, increase energy consumption, affect the heat preservation effect, and food may go bad.

4. Keep ventilation: the position of the freezer should keep air circulation, and there should not be too many sundries around it, otherwise it will affect the normal operation of the fan and motor, thus affecting the heat preservation effect.

5. Timely maintenance: such as unstable temperature, excessive noise, water leakage, etc. The freezer and equipment should be repaired or replaced in time to avoid the expansion of the fault.

The above is the insulation method of vertical freezer. By taking measures such as regular defrosting, correct loading, ensuring sealing, maintaining ventilation and timely maintenance, the service life of the freezer can be prolonged, the heat preservation effect can be improved, and the safety and hygiene of stored food can be protected.
