In large shopping malls, when the staff takes the food stored in the
Supermarket freezer, the opening and closing of the door should follow the principles of quick action, small angle, and planning. There is a plan to take out or put the food into the
supermarket freezer at a time, so as to have a plan. Avoid excessive air-conditioning overflow and excessive indoor hot air entering the supermarket
freezer. The supermarket freezer should be placed in a place with low ambient temperature and good ventilation, and there should be appropriate space around the supermarket freezer to facilitate heat dissipation.
The space utilization of the supermarket freezer also affects the power consumption of the freezer. We must pay attention to adjusting the temperature of the supermarket freezer reasonably according to seasonal changes, the type and quantity of food, so that the whole machine is always in the best working condition on the premise of ensuring the quality of the food. . The food stored in the supermarket freezer should be appropriate, not too much, and should be placed regularly. Because the volume and load of the supermarket
refrigerator are fixed, if the food is placed too much and it is too full, it will affect it. Suitable for freezer door racks: Foods that are packaged but open and won't spoil in a day or two by themselves, such as ketchup, salad dressing, tahini, hoisin sauce, cheese, butter, jam, juice, etc., as well as eggs , salted duck eggs and other egg foods.
Cooked food, yogurt, desserts, etc. directly entered are placed on the upper floor by the door. When storing these foods, supermarket freezers should avoid low temperature and prevent cross-contamination of raw and cooked foods, so they should not be placed on the lower level. Leftover food, leftover soy milk, packaged soy products, etc. are suitable to be placed on the upper back wall. Since these foods are easy to breed bacteria, the temperature of the supermarket freezer should be slightly lower than 0 °C. All kinds of vegetables and temperate fruits such as apples and pears are suitable to be placed on the lower level by the door, and they should be packed in fresh-keeping bags to avoid freezing damage due to the low temperature of the supermarket freezer. Foods that have not been cooked, but need to be stored at low temperature, such as water tofu, salted kelp shreds, etc., are suitable for placing on the lower back wall, as well as tightly packaged foods that are not afraid of cross-contamination, and foods waiting to be slowly thawed, suitable for storage. In the coldest part of the supermarket freezer, such as the lower back wall.
Minimize the number and time when supermarket freezers are opened. Hot food should be allowed to cool to room temperature naturally, and then placed in the supermarket freezer. Fruits and flowers should be washed and drained, and then wrapped in plastic bags and placed in the supermarket freezer. Layer, affecting the cooling effect of supermarket freezers and increasing power consumption. In summer, making ice cubes and cold drinks is best arranged in the evening. The temperature at night is lower, which is conducive to the heat dissipation of the condenser, and the supermarket freezer door is less open at night to store food, and the compressor has a shorter working time, saving electricity. Store food in an appropriate amount, preferably 80% of the volume, otherwise it will affect the air convection in the supermarket freezer, make food difficult to dissipate heat, affect the preservation effect, increase the working time of the compressor, and increase the power consumption.
