Embodiment 1

[0060] Embodiment 1, take meat fresh-keeping in the refrigerator as example below, as figure 2 As shown, the control rules for food not frozen and long freshness are explained: the refrigerator has an independent temperature control room for meat preservation, and this room has 1 ambient temperature detection sensor (denoted as 1# sensor) and 1 meat temperature detection Sensor (marked as 2# sensor).

[0061] Commercially available meat mainly includes hot fresh meat, cold fresh meat and frozen thawed meat. Hot fresh meat refers to meat that has not been artificially cooled after slaughter. Pork bought in the market is generally hot fresh meat. The temperature and environment of this kind of meat The temperature is close to or even higher, and can reach above 30°C in summer; chilled fresh meat and frozen and thawed meat are generally supplied to supermarkets, and the temperature of the meat is kept at 0-4°C, but the process of purchasing and returning home will cause the temp...

Embodiment 2

[0066] Example 2, the following is another control method for keeping meat from freezing and keeping fresh:

[0067] Such as image 3 As shown, the first cooling process uses the characteristics of temperature mutations to find the timing of temperature rise. The sensor needs to record this cooling process. After each subsequent cooling, it can drop to a slightly higher temperature than the first time (the temperature value obtained from the first cooling) and then directly increase the temperature, as shown in The final temperature of the first cooling 2# sensor is t 1 -Δt 1 -Δt 2 -...Δt n , then it only needs to drop to t when it is not the first cooling 1 -Δt 1 -Δt 2-...Δt n-1 Then directly enter the heating program.

Embodiment 3

[0068] Embodiment 3, in giving a kind of control mode of non-frozen and long-fresh meat

[0069] Such as Figure 4 As shown, the timing of judging the temperature rise is the temperature experience value provided by a large number of experimental data in the past, which is generally -0.5~-10°C. Once the 2# sensor reaches this temperature experience value, the 1# sensor will enter the temperature rise program and repeat the cycle control.

[0070] The present invention also provides a computer-readable storage medium on which a computer program is stored, and when the computer program is executed by a processor, the steps of the control method are realized.

[0071] The present invention also provides a refrigeration device, which includes a refrigeration cavity (or freezing cavity), i.e. a refrigeration cavity, an ambient temperature sensor, a food temperature sensor and a controller are arranged in the refrigeration cavity; the ambient temperature sensor and the food temperat...

Abstract

The invention relates to the field of refrigeration control, in particular to a control method for achieving freeze prevention and long preservation of food through temperature control, refrigerationequipment and a computer readable storage medium. According to the method, quick cooling is performed under the low environment temperature firstly, and the quality of the food is maintained to the maximum extent; then segmented gradual cooling is performed, the food is promoted to enter a stable over-cooling state; when the food is frozen, continuous step-type temperature rise is performed immediately, and the food is prevented from being frozen; and through repeated cooling, temperature stabilizing and temperature rise, the temperature of the food is always kept below 0 DEG C and above the supercooling point of -10 DEG C in most of the time, and the preservation cycle is prolonged effectively.

Description

technical field [0001] The invention relates to the field of refrigeration control, in particular to a control method, a refrigeration device and a computer-readable storage medium for realizing food not frozen and staying fresh through temperature control. Background technique [0002] At present, the temperature control methods for foods that are perishable and have a short shelf life, such as meat, mainly include the following several methods: Method 1, directly put them in the freezer, and store frozen meat at -18°C. Generally, it can be stored for several months, but there are One of the most serious problems is the inconvenience of thawing, and the quality and taste of the food after thawing are obviously reduced; Method 2, soft freezing storage, the room temperature during this time is generally between -3°C and -9°C, although food storage under this condition The time is also longer, but it will still freeze too hard and face the problem of difficult thawing; method ...
