Microwave thawing device for frozen foods

Abstract

The invention provides a microwave thawing device for frozen foods comprising a defrosting chamber for placing frozen foods to be thawed, a magnetron provided outside the defrosting chamber, a waveguide connected to the magnetron and extended into the defrosting chamber as well as a bell mouth at the end of the waveguide and located in the defrosting chamber, wherein the bell mouth is opposite to the frozen food required to be thawed. The microwave thawing device for the frozen food emits microwaves through the magnetron; and then, the microwaves are guided by the waveguide and sent by the bell mouth, so that the heated food can be heated uniformly and thawed in a short term, with the thawing efficiency improved greatly.

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...
