Embodiment Construction
[0018] Below in conjunction with accompanying drawing, the present invention will be further described:
[0019] Such as figure 1 As shown, a refrigerator with electromagnetic field-assisted fresh-keeping performance is composed of a refrigeration system and a magnetic field processing system. The refrigeration system includes a compressor, an oil separator, a condenser, a liquid storage tank, a dry filter, a sight glass, a solenoid valve, a first capillary, a second capillary, a first evaporator, a second evaporator, a check valve, Pressure reducing valve and gas-liquid separator; magnetic field processing system is composed of Helmholtz coil, adjustable and stable voltage power supply, refrigerator and freezer. The refrigeration system is based on the heat pump principle and uses double evaporators to meet the different temperature requirements of the refrigerator and freezer.
[0020] The refrigeration system adopts the capillary throttling mode, and the refrigerant is di...

Abstract
The invention discloses a refrigerator with electromagnetic field-assisted fresh-keeping performance, which is composed of a refrigeration system and a magnetic field processing system. The refrigeration system includes a compressor, an oil separator, a condenser, a liquid storage tank, a dry filter, a sight glass, and an electromagnetic valve , the first capillary, the second capillary, the first evaporator, the second evaporator, a check valve, a pressure reducing valve and a gas-liquid separator; the magnetic field processing system consists of a Helmholtz coil, an adjustable power supply, a refrigerator and The freezer is composed of the first evaporator in the freezer, the second evaporator in the freezer, the central area of the Helmholtz coil can generate a magnetic field, and the adjustable regulated power supply is used to adjust the frequency of the magnetic field, the time of electromagnetic treatment and the strength of the magnetic field size. The refrigerator of the invention can not only meet the temperature and humidity control of the food storage environment, but also can regulate the magnetic field strength in the storage room to produce sterilization, facilitate quick freezing, eliminate biological electromagnetic effects such as free radicals, and improve the quality of food preservation.
Description
technical field [0001] The invention belongs to the fields of low-temperature refrigeration, freezing and refrigeration, and food preservation, and more specifically relates to a refrigerator with electromagnetic field-assisted fresh-keeping performance suitable for short-time pretreatment physical preservation of harvested fruits and vegetables and fresh meat. Background technique [0002] According to statistics from the Food and Agriculture Organization of the United Nations (FAO), in 2013 the global output of vegetables and fruits reached 950 million tons and 790 million tons respectively. Due to the strong seasonality, regionality and high moisture content of fruits and vegetables, they are very easy to rot and deteriorate, causing huge direct economic losses. In order to solve the development problems of the fruit and vegetable industry, advanced fruit and vegetable preservation technology and diversified food cold chain systems have become the focus of research in the...
