Difference Between Refrigerator Refrigeration and Freezing, Difference Between Refrigerator Frozen a

The function of the refrigerator is to keep fresh, and the role of the freezer is to freeze.

1.The temperature settings are different.

The freezing temperature is minus 18 degrees, which can achieve the effect of quick freezing, like the fish that needs to be stored for a long time can quickly reach a very low temperature, so as to meet the requirements of preservation without destroying the meat quality as much as possible. The temperature of the refrigeration is around 5 degrees Celsius, which keeps the temperature at zero degrees Celsius.

2.The usage uses are different.

Refrigeration is used frequently in households, and because the temperature is not too low, there is still a risk of bacterial growth, so it needs to be cleaned and disinfected regularly. The frozen area is much less risky in this regard, but if you often store something with a lot of moisture, you need to defrost and de-ice regularly.

3.The role is different.

The function of the refrigerator is to keep fresh, and the role of the freezer is to freeze.

4.Storage time varies.

The freezer is used for quick-frozen food, and the food in the freezer can be stored for a long time.

5.Storing things is different.

Depending on the thermostat, it may be higher or lower. Freezing is suitable for preserving fish, shrimp, meat, fresh and other foods to avoid spoilage; Refrigeration is suitable for the preservation of most vegetables, fruits and leftover food dishes.

The temperature of the freezer is about 16 -26, which can be stored in the freezer for a long time for quick-frozen food, cold drinks and long-term meat, and the moisture in the freezer food is easy to condense into frost, and must be defrosted to a certain extent.

The temperature of the refrigerator is about 2 -10, so that the food does not frostbite and has the effect of preservation, and some vegetables, fruits, beer and drinks can be put in.

The temperature of the refrigerator room is usually around 5 degrees, which is suitable for short-term refrigeration of fruits and vegetables. The temperature of the freezer is about -18 degrees Celsius, which is suitable for storing meat that needs to be frozen for a long time.

What are the differences between refrigerated and frozen:

1. The temperature is different: the temperature of refrigeration is relatively high, generally between one degree and ten degrees, and the temperature of freezing is relatively low, generally between minus 18 degrees and minus 20 degrees.

2. Different foods to preserve: refrigeration is only suitable for preserving vegetables, fruits, leftover meals, beverages, beer, etc., while freezing is only suitable for preserving fish, meat, ice cream, ice cream, hot pot ingredients, shrimp, etc.

3. Different functions: refrigeration can slow down the enzyme reaction of food and prevent microorganisms from continuing to grow, thereby effectively slowing down the speed of food spoilage and prolonging the preservation time of food. Freezing can effectively reduce food spoilage.

4. The storage time is different: refrigeration can only store food for about a few days, while the storage time of freezing is relatively long, generally about three months to half a year.

What to pay attention to when using the refrigerator:

1. Special attention must be paid to the temperature set by the refrigerator, and the temperature set by the refrigerator should not be too high or too low, which will affect the performance of the refrigerator and increase the power consumption of the refrigerator.

2. The frequency of use of refrigerator refrigeration is very high, and the food placed will be more messy, and there will be a cross-smell, and there will be a peculiar smell inside after a long time, so the inside of the refrigerator should be cleaned frequently.

3. Do not leave the freezer open for a long time when using it, so that the cold air is easy to lose, which increases the work of the compressor, resulting in an increase in power consumption.

The difference between chilled and frozen is as follows:

1. The storage temperature is different.

Chilling is to reduce the temperature to about 0 degrees; The freezer compartment of the refrigerator is mostly in the lower part, and the freezing reduces the temperature to below -18 degrees Celsius to facilitate the storage of products for a longer period of time.

2. The degree of freshness is different.

Refrigerator chilling is to maintain the freshness of freshly killed fish, shrimp, crabs and other seafood; And freezing is to freeze the seafood products, which can be left for a long time and lose the umami of the product itself.

3. Different modes of transportation.

The transportation equipment required for chilling is relatively high and cannot be transported in large quantities; The freezing is the direct omen reed fiber is frozen and sealed, which is convenient for large-scale transportation.

4. The texture of the physical object is different.

Chilled meat is firmer and brighter in color; After being frozen at a low temperature, the meat will be slightly dry and deteriorate, resulting in a much worse taste.

Benefits of chilled versus frozen:

Chilled products are at the freezing point, the meat remains soft, and the low temperature prevents bacteria from multiplying, and the taste and nutrition are preserved to the greatest extent, making them more delicious than frozen products.

This type of freezing usually preserves the seafood by layering it with crushed ice. When we go to the supermarket to buy fish, we often see aquatic products placed on top of the ice pile, which is usually chilled. The chilled preservation method is suitable for seafood with a short transportation distance, and the time for chilled fish to leave the water is short, and the public often thinks that chilled fish is more fresh, and the market is more expensive than frozen fish.

The biggest difference is in the temperature setting, the temperature of refrigeration is generally between 2 degrees and 10 degrees, the temperature should not be too low, in case of frostbite food, the type is generally put fresh fruits and vegetables, or some commonly used seasonings, refrigeration can keep them fresh, taste better, and at the same time can extend the storage time. Especially in the summer, you can also put in drinks such as alcoholic beverages, milk yogurt, etc., and it tastes better after refrigeration. In addition, if there are too many dishes cooked at home and you don't finish a meal, you can also say that the meal is refrigerated and eaten in the jujube cavity, so that the meal will not deteriorate, and it can also reduce a lot of waste, but it is also necessary to pay attention to the classification and storage, avoid cross-flavor, and the last leftovers should not exceed three days.
