What is the difference between refrigeration and freezing in the refrigerator

The main differences between refrigeration and freezing are: different temperatures, different storage times, and different functions.

1. The temperature is different. The temperature of food stored in the refrigerator is generally 1 to 8 degrees Celsius, so that the food will not be frostbitten and will have the effect of preserving freshness. The temperature at which the food is kept in the freezer is between -18 and -20 degrees Celsius.

2. The storage time is different. Refrigeration can reduce the rate of biochemical reactions and the rate of change caused by microorganisms, extending the life of fresh food and processed products. However, in order to ensure the nutrition of the ingredients, it is recommended to consume the food stored in the refrigerator as soon as possible.

FreezingSince most of the bacteria are inhibited due to the lower temperature, the freezer keeps the food for a longer time.

3. The role is different. The function of the refrigerator is to preserve the freshness of most vegetables, fruits and leftovers. The function of the freezer is to freeze quickly, which is suitable for preserving fresh foods such as fish, shrimp and meat.

The difference is that the temperature varies greatly.

The temperature of the freezer is very low, usually set and adjusted at about minus 18 degrees, which is used for long-term freezing and preservation of fresh food, which is the long-term preservation of meat food.

The temperature of the refrigerator is usually between 2 and 8 degrees above zero, which is used to keep fruits and vegetables fresh.

Refrigeration is refrigeration that is generally kept at 2-1 degrees Celsius. Freezing is freezing, and the temperature is generally between -15-3 degrees Celsius.

The refrigeration temperature should not be too low to prevent frostbite food, generally put fresh fruits and vegetables, or some commonly used spices, refrigeration can keep them fresh, taste better, and can prolong the storage time.

The temperature of the freezer is much lower, and if the temperature is slightly higher, the freezing is not thick, which may cause the stored meat to spoil. Frozen generally store chicken, duck, fish and some quick-frozen foods that can be used for a long time, and take them out to melt ice in advance when you need to eat.

To put it simply, the temperature of refrigeration is above freezing.

Vegetables, fruits, drinks, eggs, etc. can be placed here.

It will not freeze and can extend the shelf life, but it will still rot after a long time, and the freezing temperature is below zero.

Fish, meat, frozen food, popsicles, etc. can be placed here.

Food freezes and does not spoil easily.

However, it will gradually lose moisture over time.

The taste deteriorates, the nutrition deteriorates.

First, the temperature setting is different.

1. The freezing temperature is minus 18 degrees, which can achieve the effect of quick freezing, like the fish that needs to be placed for a long time can quickly reach a very low temperature, so as to meet the requirements of preservation without damaging the meat quality as much as possible;

2. The temperature of refrigeration is about 5 degrees, which can always keep the temperature at the level of zero degrees.

Second, the usage and use are different.

1. Families use refrigeration more frequently, and because the temperature is not too low, there is still a risk of breeding bacteria, so it needs to be cleaned and disinfected regularly;

2. The risk of the frozen area in this regard is much smaller, but if you often store something with a lot of moisture, you need to defrost and de-ice regularly.

Third, the role is different.

1. The function of the refrigerator is to keep it fresh;

2. The function of the freezer is quick-freezing.

Fourth, the storage time is different.

1. The refrigerated room shall be subject to non-frostbite food and freshness;

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

Fifth, the storage of things is different.

1. According to the thermostat control, it is different, higher or lower. Freezing is suitable for preserving fish, shrimp, meat, fresh and other foods to avoid spoilage;

2. Refrigeration is suitable for the preservation of most vegetables, fruits and leftover food dishes.

I hope it can help you, remember to give it a thumbs up.

Question: Why is my freezer set to quick-freeze, why isn't the meat frozen? What is the reason?

My freezer is set to quick-freeze, why isn't the meat frozen? What is the reason?

The possible reasons for the answer are as follows: 1. The door seal is not tight, or the refrigerator is close to the heat source area, which affects the heat dissipation. 2. Freezer compartment of the refrigerator"The frost is too thick, the ice is too thick"Defrost immediately. 3. If the thermostat is not adjusted properly, debug the thermostat until the freezer freezes.

4. If the above problems are basically normal, there may be a lack of fluorine, and it is recommended that professionals repair them.

The temperature of the refrigerator room is 0-10 degrees Celsius.

Freezer temperature 0-minus 12-18 degrees.

1.Refrigerator: AShelf: frozen on top and refrigerated on bottom.

Treat each case separately. But all of them have a certain time limit.

Fainted to death ,......

Generally speaking, from the appearance, the one with the drawer is frozen, and the other is refrigerated

The difference between refrigeration and freezing in the refrigerator: different temperature settings, different functions, different storage times, and different things to store.

1. The temperature setting is different

The freezing temperature is usually controlled at minus 18 degrees Celsius in order to achieve the purpose of inhibiting bacteria, such as fish and meat that need to be stored for a long time, in an environment of more than ten degrees below zero, it can not only destroy the meat quality but also meet the requirements of long-term preservation. The temperature of refrigeration is usually controlled at about 5 degrees, which will not frostbite the food and keep the food fresh.

2. The role is different

Refrigeration can slow down the enzymatic reaction of food and prevent the growth of microorganisms, which can effectively slow down the rate of food spoilage and make food last longer. Freezing can effectively inhibit bacteria, reduce the rate of food spoilage and chemical reactions, let the moisture of food form ice, prevent the growth of microorganisms in food, and prolong the storage time of food.

3. The storage time is different

The refrigerator is mainly used for non-frostbite food and can keep food fresh, while the freezer room is mainly used for quick-frozen food, so that the food can be stored for a longer time.

4. Store things differently

Freezing is suitable for preserving some fish, shrimp, meat and other foods to prevent them from spoiling, while refrigeration is suitable for storing most of the leftover food dishes such as vegetables and fruits.

The difference between refrigeration and freezing in the refrigerator is: temperature difference, shelf life, type of ingredients, freezing method, ironing and thawing.

1. Temperature difference: The temperature of the refrigerated area is usually 0 to 5 degrees Celsius, which is suitable for storing fresh ingredients and perishable foods; The temperature of the freezer area is usually below -18 degrees Celsius, which is suitable for freezing food to keep fresh.

2. Preservation time: The refrigeration area can extend the preservation time of food, but generally not more than one week; The frozen zone can greatly extend the freshness of the food, often for months to years.

3. Types of ingredients: The refrigerated area is suitable for storing fresh vegetables, fruits, milk, cheese and other ingredients; The freezer area is suitable for storing meat, fish, frozen food and other ingredients that need to be kept fresh for a long time.

4. Freezing method: The storage method of the refrigerated area is usually to adjust the temperature of the cave through the refrigerator; The freezer area requires the use of a special freezer, such as a freezer or freezer.

5. Ironing and thawing: In the refrigerated area, food generally only needs to be ironed before it is ready to eat; In the freezer zone, food needs to be thawed before it can be eaten, and the thawing time varies depending on the type and volume of food.

1. Different meanings:

Freezing refers to the process of freezing liquid water in fish, meat and other foods into a solid state by means of low temperatures. Refrigeration is a preservation method for cooled food at the refrigeration temperature (often above freezing), especially for fruits and vegetables, mainly to delay their life metabolism process as much as possible and maintain their freshness. Preservation means to keep perishable foods such as vegetables, fruits, and meat fresh.

2. The temperature is different

Refrigeration and preservation of food are generally at a temperature of 1 to 8 degrees Celsius, so that the food is not frostbitten and has a freshness effect. The temperature at which the food is kept in the freezer is between -18 and -20 degrees Celsius.

3. The storage time is different

Refrigeration can reduce the rate of biochemical reactions and the rate of change caused by microorganisms, and prolong the life of fresh food and processed products, and the storage time is usually about 3 days, but in order to ensure the nutrition of the ingredients, it is recommended to eat the food stored in the refrigerator as soon as possible.

The storage time is about 1 day. Freezing is due to the lower temperature, most of the bacteria are inhibited, so the food is kept in the freezer for a longer time, usually more than 7 days.

4. Different functions:

Refrigeration and preservation are used for short-term preservatives, which are suitable for the preservation of most vegetables, fruits and leftover food dishes. The function of freezing is to freeze quickly, which is suitable for preserving fresh foods such as fish, shrimp and meat.

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. The imitation food of Baoyou is different: refrigeration is only suitable for preserving vegetables, fruits, leftover meals, beverages, beer, etc., while freezing is only suitable for preserving fish, meat, 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 Bingshen Qiaoqiao box 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 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.
