Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention will be further described:

[0019] like 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 divid...

Abstract

The invention discloses a refrigerator with an electromagnetic field assisted fresh keeping property. The refrigerator comprises a refrigeration system and a magnetic field treatment system, wherein the refrigeration system comprises a compressor, an oil separator, a condenser, a liquid storage tank, a dry filter, a liquid observation mirror, an electromagnetic valve, a first capillary tube, a second capillary tube, a first evaporator, a second evaporator, a check valve, a pressure reducing valve and a gas-liquid separator; the magnetic field treatment system comprises helmholtz coils, an adjustable stabilized voltage supply, a refrigeration chamber and a freezing chamber; the first evaporator is arranged inside the refrigeration chamber; the second evaporator is arranged inside the freezing chamber; the central zones of the helmholtz coils can generate magnetic fields; and the adjustable stabilized voltage supply is used for adjusting the magnetic field frequency, electromagnetic treatment time and magnetic field intensity. According to the refrigerator, the temperature and humidity control of a food storage environment can be achieved, the magnetic field intensity in a storage chamber can be regulated as well, a biological electromagnetic effect of sterilization, quick freezing facilitation and free radical removal is generated, and the effect of improving the food fresh keeping quality is improved.

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...
