High-humidity radio frequency unfreezing and refrigerating system

Abstract

The invention discloses a high-humidity radio frequency unfreezing and refrigerating system and aims at providing a system capable of achieving both the food freezing function and the sterilizing andquick unfreezing functions. The high-humidity radio frequency unfreezing and refrigerating system comprises a freezing and refrigerating circulating system, a high-humidity radio frequency unfreezingsystem and an auxiliary humidifying system. The high-humidity radio frequency unfreezing system comprises a radio frequency power module, an unfreezing tank with an upper cover, a positive plate, a negative plate and a carrying platform, and the positive plate, the negative plate and the carrying platform are located in the unfreezing tank. An evaporator is arranged on the upper portion of the interior of the unfreezing tank. The positive plate and the negative plate are arranged on the two sides of the carrying platform in parallel and are connected with a positive pole and a negative pole ofthe radio frequency power module correspondingly to form a radio frequency heating unit. The auxiliary humidifying system comprises a water tank, a gas-liquid separator, a liquid atomization nozzle and a gas nozzle. A condenser is arranged in the water tank. The high-humidity radio frequency unfreezing and refrigerating system provided by the invention has the freezing and quick unfreezing functions, and the problem that food is dried during the radio frequency unfreezing process due to overheating of sharp corners is solved. Moreover, the high-humidity radio frequency unfreezing and refrigerating system is high in heating rate and can protect the food against deterioration due to long-time heating.

Description

Technical field [0001] The invention relates to the technical field of food storage, and more specifically, to a high-humidity radio frequency thawing refrigeration system. Background technique [0002] With the emergence of swine fever and its impact on my country’s meat production, the mode of meat products will change from "unification of production and sales" to "separation of production and sales". This means that fresh meat will decrease, frozen meat will increase, and meat production will increase. The thawing technology needs great development. [0003] At present, in the research on meat thawing, the patent document with the patent number 201821234781.0 and the invention titled "A kind of frozen meat preservation thawing warehouse" discloses a thawing equipment, including the thawing warehouse body, air heater, and thawing warehouse. There are shelves in the body, mainly for hot air thawing, because the hot air thawing process often causes heat to be concentrated in a cert...

Problems solved by technology

[0003] At present, in the research on meat thawing, a patent document with the patent number 201821234781.0 and the invention name "A Frozen Meat Fresh-keeping and Thawing Storage" discloses a thawing equipment, including the thawing storage body, the air heater, the thawing storage There are shelves in the body, mainly for hot air thawing, because the hot air thawing process often causes heat to concentrate on a certain part, affecting the quality of thawed meat

Other thawing technologies also have problems such as large amount of pyrolyzed liquid, large quality loss, uneven heating, and poor quality of thawed meat.
