Embodiment 1

[0033] A liquid-cooled flash-freezing method and device for keeping meat products fresh according to the present invention. The operation process for freezing a whole pig of relatively large meat products is as follows:

[0034] The freezing liquid is prepared according to the following mass percentages: 15% sodium chloride, 20% ethanol, 8% dextran, and the rest are distilled water; the flash freezing liquid can rapidly cool down in 5 minutes to -35℃, and can keep the whole head of pork frozen at low temperature. Put the whole frozen pork product into the flash freezing pool and put it in the flash freezing pool, pour the low-temperature flash freezing liquid into the pre-cooling pool, and turn on the machine to cool the refrigeration unit in the pre-cooling pool. When the low-temperature flash freezing liquid reaches the ideal temperature, the circulating pump pipe between the pre-cooling pool and the flash freezing pool is turned on, and the flow of the low-temperature flash...

Embodiment 2

[0036] A liquid-cooled flash-freezing method and device for keeping meat products fresh according to the present invention. The operation process for freezing small-sized meat products leg of lamb is as follows: prepare the freezing liquid according to the following mass percentages: 20% sodium chloride, 15% ethanol, 10% dextran, and the rest is distilled water; the flash freezing liquid can quickly cool down to -30°C in 5 minutes under the refrigeration condition of -40°C, and can maintain low temperature to freeze lamb leg products. Put the frozen leg of lamb into the flash freezing pool and pour the low-temperature flash freezing liquid into the pre-cooling pool, and turn on the machine to cool the refrigeration unit in the pre-cooling pool. When the low-temperature flash freezing liquid reaches the ideal temperature, the circulating pump pipe between the pre-cooling pool and the flash freezing pool is turned on, and the flow of the low-temperature flash freezing liquid is o...

Embodiment 3

[0038] A liquid-cooled flash-freezing method and device for keeping meat products fresh according to the present invention. The operation process for freezing beef shanks of small-sized meat products is as follows: the freezing liquid is prepared according to the following mass percentages: 18% sodium chloride, 17% ethanol, 5% dextran, and the rest is distilled water; the flash freezing liquid can quickly cool down to -30°C in 10 minutes under the refrigeration condition of -40°C, and can keep the low temperature of -30°C to freeze beef legs. Put the frozen beef leg into the flash freezing pool and put it in place, pour the low-temperature flash freezing liquid into the pre-cooling pool, and turn on the machine to cool the refrigeration unit in the pre-cooling pool. When the low-temperature flash freezing liquid reaches the ideal temperature, the circulating pump pipe between the pre-cooling pool and the flash freezing pool is opened, and the flow of the low-temperature quick-f...

Abstract

The invention discloses a liquid cooling flash-freezing device and method for fresh keeping of meat products. The liquid cooling flash-freezing device comprises a low-temperature flash-freezing liquid circulating pond, a microwave-assisted freezing device, a controller and low-temperature flash freezing liquid circulated in the low-temperature flash freezing liquid circulating pond, wherein the low-temperature flash freezing liquid circulating pool comprises a precooling pond and a flash freezing pond, the precooling pond and the flash freezing pond are connected through circulating pump pipes to form a circulating system; the microwave-assisted freezing device is provided with magnetrons and a microwave resonance cavity, wherein the magnetrons are mounted on a mounting plate and connected with the controller; the microwave resonance cavity is connected with the magnetrons; the low-temperature flash freezing liquid mainly consists of the following substances in percentage by mass: 15-20% of sodium chloride, 15-20% of ethanol, 5-10% of glucan, and the balance of distilled water. According to the low-temperature flash freezing device for the meat products, the flash freezing liquid and the flash freezing device are in cooperating operation, so that the condition that nutrients of frozen meat products run off under the condition that the frozen meat products are stored for a long term can be reduced, and the suitable targets comprise the meat products including common pork, beef, mutton and the like.

Description

technical field [0001] The invention relates to a liquid-cooled flash-freezing method and device, in particular to a meat product designed to solve the problem of uneven freezing and low freezing efficiency in the low-temperature freezing process of meat products resulting in damage and inactivation of animal cells after freezing. A liquid cooling and flash freezing method and device for product freshness preservation. Background technique [0002] Meat products (pigs, cattle, sheep, etc.) are foods with high edible value, which can provide protein, fat, inorganic salts and vitamins needed by the human body, and are one of the important foods for human beings. However, the animal enzymes in animal cells and the nutrient environment inside the cells that are suitable for the growth and reproduction of microorganisms make meat products prone to spoilage, which restricts the long-term preservation of meat products. [0003] Low-temperature freezing technology is a common way t...
