Problems solved by technology

Among them, natural thawing and refrigerated thawing are aimed at thawing frozen food, especially for large pieces of meat. The thawing time is longer and there is serious juice loss, which affects the taste and nutritional content of food.
Soaking and thawing is mainly aimed at thawing meat, which can relatively shorten the thawing time, but there is also the problem of juice loss, serious discoloration, and easy to breed bacteria
Microwave oven thawing has a significant effect on raising the temperature of frozen food in a short period of time. There are various types of microwave ovens used for thawing. Setting, artificially setting the thawing power and thawing time will result in incomplete thawing or setting the thawing time too long will cause discoloration of the meat after thawing, affecting the taste and nutritional content of food

Abstract

The invention belongs to the technical field of radio frequency unfreezing, and discloses a radio frequency unfreezing device. The radio frequency unfreezing device comprises an unfreezing cavity, a housing, a radio frequency source, a radio frequency power amplifier and a radio frequency antenna, wherein the radio frequency source and the radio frequency power amplifier are arranged between the unfreezing cavity and the housing; the radio frequency source is connected with the radio frequency power amplifier, and is used for amplifying the radio frequency power produced by the radio frequencysource to a set power; the radio frequency antenna is arranged on the inner wall of the unfreezing cavity; and the radio frequency antenna is connected with the radio frequency power amplifier, and is used for radiating the radio frequency produced by the radio frequency source to the unfreezing cavity. Through the adoption of the radio frequency unfreezing device provided by the embodiment of the invention, the inner side and the outer side of the food to be unfrozen are smoothly heated, the heating of the food to be unfrozen is guaranteed to be uniform, and the unfreezing effect is improved.

Description

technical field [0001] The invention relates to the technical field of radio frequency thawing, in particular to a radio frequency thawing device. Background technique [0002] The thawing methods for food thawing mainly include: natural thawing, immersion thawing, refrigeration thawing and microwave thawing. Among them, natural thawing and refrigerated thawing are aimed at thawing frozen food, especially for large pieces of meat, the thawing time is long, and there is a serious loss of juice, which affects the taste and nutritional content of the food. Soaking and thawing is mainly aimed at thawing meat, which can relatively shorten the thawing time, but there is also the problem of juice loss, serious discoloration, and easy to breed bacteria. Microwave thawing has an obvious effect on the temperature rise of frozen food in a short time. There are various types of microwave ovens used for thawing. When determining the thawing power and thawing time, the weight of the thaw...
