Quick-freezing control method for reducing freezing damage of food and quick-freezing refrigerator

Abstract

The invention provides a quick-freezing control method for reducing freezing damage of food, which adopts a refrigerating system to generate cold air to cool stored objects. In the quick-freezing process, the cooling to a non-quick-freezing area is reduced or stopped so as to increase the cooling to a quick-freezing area; the temperature of the stored object is monitored in real time; and when thetemperature of the stored object reaches a first preset temperature, the rotating speed of a condenser fan in the refrigerating system is increased, and the temperature of the stored object is reduced to a second preset temperature, wherein the first preset temperature is higher than the maximum value of the maximum ice crystal generation zone temperature interval, and the second preset temperature is lower than the minimum value of the maximum ice crystal generation zone temperature interval. The invention further provides a quick-freezing refrigerator which is more energy-saving while beingused for reducing the freezing damage of food and achieving quick-freezing.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a quick-freezing control method for reducing food freezing damage and a quick-freezing refrigerator. Background technique [0002] In order to better maintain the nutrition of frozen food, ordinary freezing, rapid freezing and other freezing methods are usually used for food preservation. However, traditional ordinary freezing has disadvantages such as uneven temperature control in the freezing chamber and staying in the maximum ice crystal formation zone for a long time. ; For example, CN106123441A mentions a quick-freezing method in a refrigerator with quick-freezing function, but the energy consumption will increase due to the inability to intelligently identify the temperature at which food reaches the ice crystal formation zone. In CN2527938Y, the thawing plate with quick-freezing function is placed in the refrigerator, which increases the cost and is not economical and practica...

[0002] In order to better maintain the nutrition of frozen food, ordinary freezing, rapid freezing and other freezing methods are usually used for food preservation. However, traditional ordinary freezing has disadvantages such as uneven temperature control in the freezing chamber and staying in the maximum ice crystal formation zone for a long time. For example, a kind of quick-freezing method is mentioned in a refrigerator with quick-freezing function in CN106123441A, but the energy consumption will increase due to the inability to intelligently identify the temperature at which the food reaches the ice crystal formation zone

In CN2527938Y, the thawing plate with quick-freezing function is placed in the refrigerator, which increases the cost and is not economical and practical

[0005] (2) Unable to intelligently identify the temperature range of the largest ice crystal zone

[0006] (3) Large energy consumption, and cause the temperature of other rooms to drop synchronously
