Microwave unfreezing apparatus for frozen foods

Abstract

The invention provides a microwave unfreezing apparatus for frozen foods. The microwave unfreezing apparatus comprises a unfreezing room used for placing to-be-unfrozen frozen foods, magnetic control tubes arranged outside the unfreezing room, waveguide tubes which are connected with the corresponding magnetic control tubes and extend into the unfreezing room, and horn mouths which are positioned at the tail ends of the corresponding waveguide tubes and positioned in the unfreezing room, wherein the horn mouths are opposite to the to-be-unfrozen frozen foods; a supporting plate used for placing the to-be-unfrozen frozen foods is arranged in the middle part of the unfreezing room; the supporting plate horizontally supports the middle part of the unfreezing room, and a supporting rod is arranged at the bottom end of the supporting plate in a supporting manner; and the bottom end of the supporting rod extends out of the outer side of the unfreezing room, and is connected with a motor which is used for driving the supporting rod to drive the supporting plate to rotate along a horizontal surface. According to the microwave unfreezing apparatus for the frozen foods, microwave is generated through the magnetic control tubes; then the microwave is guided by the waveguide tubes and to be given out through the horn mouths, so that the heated food can be heated uniformly; and in addition, the food can be unfrozen and heated within a short time, thereby improving the unfreezing efficiency.

Description

technical field [0001] The invention relates to the technical field of thawing, in particular to a microwave thawing device for frozen food. Background technique [0002] Some frozen items such as quick-frozen food are generally stored in an environment below -18°C, and need to be thawed before production. The current common thawing methods mainly include the following: [0003] 1. Ordinary water bath thawing is also called natural thawing. It is to thaw frozen products directly in room temperature water or cold water. It usually takes several hours to ten hours or even a few days to achieve thawing. If the time is too long, it will damage the food. frozen product quality; [0004] 2. Or there is another commonly used low-temperature thawing method, which is to thaw frozen items in a fresh-keeping freezer at 0°C to 4°C. Although this method keeps fresh, it takes longer; [0005] The above-mentioned thawing equipment mainly has the disadvantages of slow thawing speed and lo...
