Embodiment Construction

[0039] figure 1 It is a schematic perspective view of a partial structure diagram of a refrigerating and freezing device according to an embodiment of the present invention, and the arrows in the figure indicate the flow direction of the cold air flow. Such as figure 1 As shown, the embodiment of the present invention provides a refrigerating and freezing device, and the refrigerating and freezing device can be generally known refrigerators, freezers and other devices with refrigeration and preservation functions. Specifically, the refrigerating and freezing device may include an outer shell, an inner container arranged in the outer shell, and an insulating material filled between the outer shell and the inner container. A storage compartment 20 for storing frozen food 60 is defined in the inner container. A storage drawer may be provided in the storage compartment 20, so that the storage compartment 20 forms an airtight storage space. In some other embodiments, a door for ...

Abstract

The invention provides a refrigeration and freezing device and a freezing method thereof. The refrigeration and freezing device comprises a liner, a refrigeration system, an interference device and an ultrasonic generation device, wherein a storage chamber for storing frozen foods is limited in the liner; the refrigeration system is configured to be controlled to supply cooling capacity to the storage chamber, so that the temperature of the storage chamber is reduced to and kept at a crystallization point temperature first preset time of the frozen foods, and then, is reduced to and kept at a preset preservation temperature of the frozen foods; the interference device is configured to be started to interfere the frozen foods after the temperature in the storage chamber is reduced to the crystallization point temperature first preset time, and works for a second preset time; and the ultrasonic generation device is configured to be started to apply ultrasonic waves to the frozen foods when the interference device is stopped working, and works for a third preset time. The refrigeration and freezing device and the freezing method thereof excellently preserve the cell integrity of the foods in the freezing process, and perfectly guarantee the freezing quality of such foods as meat loafs.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration and freezing device and a freezing method thereof. Background technique [0002] During the use of the refrigerator, most users keep a lot of meat in the freezer, but the color of the frozen meat is dull, the thawing juice is lost, and the taste of the frozen meat is poor, which affects the user experience of the refrigerator. At present, there are mainly two schemes to achieve high-quality freezing in refrigerators on the market. One is to achieve rapid freezing and preservation of food through strong wind cooling or replacing the heat transfer medium; the other is to achieve supercooling and freezing by making the food enter a supercooled state. The quick-freezing method can effectively improve the quality of food freezing, but it still crystallizes from the outside to the inside when it freezes, and it cannot completely avoid the disadvantages o...
