Description

Technical Field

[0001] The utility model belongs to the technical field of food preservation equipment, and in particular relates to a fresh-keeping electric field generator and a cold storage thereof. Background Art

[0002] Due to the underdeveloped food preservation technology, huge losses occur during the transportation and storage of food. In particular, fruits, vegetables, meats, and seafood often need to be transported and stored over long distances due to the uneven distribution of their origins. In this process, low-temperature methods such as refrigeration and freezing are usually used for transportation and storage. For example, in the prior art, a Chinese patent with publication number CN203646419U discloses a vacuum low-temperature preservation device, which also mentions that low-temperature preservation is achieved by refrigeration. However, low temperature can only slow down the bacterial growth and oxidation and degradation of food, so low temperature can only be used for preservation in a relatively short period of time.

[0003] As my country's living standards improve, consumers have higher and higher requirements for food quality, and pay more attention to the freshness and safety of food. However, the existing preservation technology is mainly achieved by controlling temperature, and the preservation effect is not good; research has found that the metabolism of fruits and vegetables and other foods will slow down under the influence of high-voltage electric fields, which can extend the shelf life of food; however, the current preservation technology combined with high-voltage electric fields still has some disadvantages:

[0004] 1) The output current is large, which may cause hidden dangers to electrical safety;

[0005] 2) Equipment that generates high-voltage electric fields is susceptible to external electromagnetic interference, resulting in increased electromagnetic noise in the output current;
