Microwave oven with high-voltage electrostatic preservation thawing device

Abstract

The invention relates a microwave oven with a high-voltage electrostatic preservation thawing device. The microwave oven comprises a microwave oven body, a control panel and a high-voltage electrostatic preservation thawing device composed of a high-voltage electrostatic generator, a discharger and a metal plate. The front surface of the microwave oven body is provided with a door. The control panel is arranged beside the door. An electrostatic controller is connected to a microwave oven power supply and the control panel. The discharger and the metal plate are connected to the electrostatic controller, are respectively arranged on or inserted into left and right surfaces or upper and lower surfaces in the microwave oven body and are insulative to the microwave oven body. The microwave oven can realize preservation and thawing of frozen foods, uniform distribution of temperatures of unfrozen foods and a small loss of a juice and prevent food oil acidification. The high voltage electrostatic field can inhibit and kill microorganisms, is conducive to food quality keeping, greatly prolongs preservation time after thawing and solves the problem that the existing microwave oven cannot realize uniform thawing and preservation through heating unfreezing.

Description

technical field [0001] The invention specifically relates to a microwave oven with a high-voltage electrostatic fresh-keeping and thawing device. Background technique [0002] Household microwave ovens have brought us a lot of convenience, among which microwave thawing has the advantages of fast thawing speed and good product quality after thawing. However, microwave heating and thawing is also strong on the surface and weak on the inside, especially the heating of the corners and protrusions, which will cause thermal denaturation. In addition, due to the uneven meat tissue, the calorific value of water is obviously greater than that of ice, so there will be a large temperature imbalance. At the same time, the meat products after microwave thawing should not be stored for too long, otherwise they will spoil soon. [0003] High-voltage electrostatic fresh-keeping and thawing is a technology that thaws both inside and outside at the same time. This method is to place the fr...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problem of inconsistent thawing effects on the surface and inside of the existing microwave heating and thawing meat products. In addition, due to the uneven meat tissue, the calorific value of water is obviously greater than that of ice, so there will be a large temperature imbalance , usually cooked on the outside, with ice in the center of the food

There will also be problems of precipitation of a large amount of blood and surface denaturation when heated, which will seriously affect the quality of food

At the same time, meat products have the problem of being perishable and deteriorating after thawing and cannot be kept fresh.
