Embodiment

[0047] refer to figure 1 , figure 1 It is a schematic flow chart of a method for controlling instant freezing of a refrigeration device provided in an embodiment of the present application. Such as figure 1 As shown, the method at least includes the following steps:

[0048] S101: Control the refrigeration equipment to perform the supercooling and temperature reduction phase, the super cooling and temperature reduction phase includes a plurality of sub-phases, and each sub-phase includes a corresponding preset target temperature and preset running time; when performing the super cooling and temperature reduction phase, according to the sub-phase The preset target temperature corresponding to the stage is gradually reduced in order to execute each sub-stage in turn, so that the food in the instant freezing chamber enters a supercooled state;

[0049]That is to say, multiple sub-stages for cooling are respectively performed to cool down the food in the instant freezing chambe...

Abstract

The present application relates to an instant freezing control method, device, controller and refrigeration equipment of refrigeration equipment. Among them, by setting the supercooling and cooling stage, the food in the instant freezing chamber of the refrigeration equipment enters a supercooled state, even if the food enters a state of freezing temperature but not freezing, so as to ensure that the microstructure of the food is not damaged by ice crystals. The supercooling maintenance stage keeps the food in the supercooled state for a long time, so that it can fully ensure that the food enters the supercooled state evenly and uniformly, which is conducive to the release of the supercooled state of the food in the subsequent steps, and can effectively improve the freshness of the food.

Description

technical field [0001] The present application relates to the technical field of instant freezing of refrigerators, in particular to a method, device, controller and refrigeration equipment for instant freezing control of refrigeration equipment. 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, while 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 ; and although rapid freezing can pass through the maximum ice crystal formation zone quickly, the production cost is higher, which is unfavorable for popularizing and applying on the refrigerator. [0003] Based on this, an instant freezing technology is proposed in the prior art to preserve food by making the food enter a supercooled state, but at present, the solut...
