1. The refrigeration temperature of the refrigerator is different in different seasons:
The indoor temperature is relatively high in summer, and the temperature in the refrigerator can be appropriately higher, which is both energy-saving and useful. It is best to adjust it to 7-8 degrees. The indoor temperature is low in winter, so the refrigerator temperature should not be affected by the indoor temperature. Therefore, it is necessary to reduce the temperature of the refrigerator by 3-4 degrees, so as to keep it fresh.
2. Different types of refrigeration have different refrigeration temperatures:
(1) Frozen meat: 1 degree
Meat is usually frozen in the refrigerator. When you need it, just wait for it to melt and then cut it into pieces to cook, so the raw meat you buy is usually put in the freezer. If it is meat to be eaten the next day, it can actually be put in the freezer to let the meat melt slowly. You can fry it directly next time. The temperature of the freezer is generally 1 degree.
(2) Frozen fish: 5 degrees.
Fish are easily damaged. After all, the environment in which fish grow is low temperature underwater. Generally speaking, fish freeze above MINUS 18 degrees. If it is only frozen for a few days tomorrow and the day after tomorrow, it can be put in a freezer at about 5 degrees, but if it is cooked fish, it needs to be frozen at about 2 degrees after eating the rest.
(3) Frozen poultry: -3 degrees.
Poultry meat is generally afraid of corruption, so it is the best choice to put it in the freezer. However, you can put it in the freezer if you need it urgently. Generally speaking, it is ok to keep fresh first. If it is frozen, it needs about MINUS 10 degrees. If it is stored because of the epidemic, it can be refrigerated even if it is used.
(4) Frozen vegetables: 3 degrees.
Vegetables are generally afraid of freezing, but the low temperature can ensure that they will not be corroded. Therefore, the refrigeration temperature of vegetables should not be too low, and they should not be put together during refrigeration. The refrigerator should be ventilated, so it will still be bad if it is not refrigerated. It's best to dry the water on it before refrigeration, otherwise it will freeze.
(5) Refrigerated milk: about 5 degrees.
Generally, the shelf life of milk is relatively short. After buying it back, it may be broken within half a month. So when you refrigerate milk, the temperature should not be too low, otherwise it will affect the activities of various nutrients in milk. About 5 degrees is best. All kinds of milk and yogurt have different freezing temperatures. Please check the instructions of the goods.
3. Refrigeration temperature of gear refrigerator:
Most household refrigerators do not have an accurate temperature regulator, but have a gear regulator, which is divided into 1-5 or 1-7 gears. Generally speaking, the summer temperature should be set between 3 and 4, and the winter temperature should be set between 1~2 or 2. One principle is to keep the freezer temperature at 5~ 10 degrees Celsius. Fresh fish and meat should be packed in plastic bags and then stored in the refrigerator. Vegetables and fruits should be dried on the outer surface, put in the bottom of the refrigerator and stored at zero temperature. It should be noted that the temperature distribution in the cold storage room is not very uniform, but the temperature gradually increases from top to bottom. Generally, the upper temperature is relatively low and the lower temperature is relatively high.
