Embodiment 1

[0121] The specific steps of the two-stage thawing method for ultra-low temperature tuna include: .

[0122] B1: Quickly weigh the ultra-low temperature tuna to be thawed and put it into the thawing device.

[0123] B2: Enter the product quality as 0.50kg through the key input module, and set the ambient temperature in the high-temperature thawing stage as 10°C. The liquid crystal display shows that the thawing time in the high temperature stage is 1 hour and 55 minutes, and the high temperature thawing stage starts. The temperature monitoring module starts to keep the temperature stable.

[0124] B3: When the remaining time displayed on the LCD screen is 0, there will be a prompt sound. The temperature monitoring module controls the ambient temperature to drop to 4°C, and the liquid crystal display shows that the low-temperature thawing stage time is 14 hours and 30 minutes. The temperature control module monitors the ambient temperature, and if it exceeds the set range, t...

Embodiment 2

[0136] The specific steps of the two-stage thawing method for high-grade steaks include:

[0137] C1: Quickly weigh the high-grade steak to be thawed and put it into the thawing device.

[0138] C2: Enter the product quality as 0.25kg through the key input module, and set the ambient temperature in the high-temperature thawing stage to 20°C. The thawing time of the liquid crystal display output high temperature stage is 1 hour and 20 minutes, and the high temperature thawing stage starts. The temperature monitoring module starts to keep the temperature stable.

[0139] C3: When the remaining time displayed on the LCD screen is 0, there will be a prompt sound. The temperature monitoring module controls the ambient temperature to drop to 4°C, and the liquid crystal display shows that the low-temperature thawing stage time is 8 hours and 35 minutes. The temperature control module monitors the ambient temperature, and if it exceeds the set range, the sound and light alarm modul...

Abstract

The invention relates to a frozen meat product thawing method and device. The method includes the steps: acquiring the quality of a frozen meat product to be thawed, a first preset environmental temperature and a second preset environmental temperature; respectively determining first time needed by a first thawing stage and second time needed by a second thawing stage through a preset meat product thawing model according to the quality of the frozen meat product to be thawed, the first preset environmental temperature and the second preset environmental temperature; controlling the thawing device to thaw the frozen meat product to be thawed in a two-stage mode according to the first preset environmental temperature, the first time, the second preset environmental temperature and the second time. The requirement of a user for automatic thawing of ultralow-temperature frozen meat products can be met, thawing time can be shortened by the high-temperature thawing stage and the low-temperature thawing stage, the problem of poor food sanitation caused by excessive thawing of product surfaces is avoided, and eating safety of the products can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of thawing frozen meat products, in particular to a method and device for thawing frozen meat products. Background technique [0002] Some meat products (such as tuna, etc.) are limited by their own physical and chemical characteristics, such as high content of unsaturated fatty acids, protein variability, etc., and their nutritional and / or sensory qualities are prone to rapid deterioration under ordinary freezing conditions, so ultra-low temperature freezing is usually used for storage. In addition, in order to adapt to the high-end consumer market and maintain the excellent quality of meat products, some enterprises also adopt ultra-low temperature freezing storage. Under the condition of ultra-low temperature freezing, the physical and chemical reactions of meat food are almost stagnant, so it can maintain its original good quality for a long time. [0003] Frozen meat products need to be thawed before e...
