Technical Field

The invention relates to the field of food cold chain and cold chain equipment, in particular to a flow state ice fresh-keeping refrigerator.

Background

The fruits and vegetables are stored in a low-temperature and high-humidity environment, the metabolism of the fruits and vegetables can be inhibited, the fruits and vegetables are in a living state, and the fresh-keeping effect of the fruits and vegetables is closer to that of fresh fruits and vegetables. The development of the low-temperature and high-humidity ice temperature technology in Japan is mature, and a large number of ice temperature devices are developed, such as an ice temperature container, an ice temperature transport vehicle, an ice temperature storage warehouse, an ice temperature showcase, an ice temperature refrigerator, an ice temperature vegetable basket for purchasing food, and the like. In China, as a terminal of a food cold chain, namely a household refrigerator, the preservation performance of the refrigerator is continuously improved, and various preservation technologies appear, such as: precise temperature control fresh-keeping, wide temperature zone fresh-keeping, zero-degree vacuum fresh-keeping, three-dimensional dynamic sterilization fresh-keeping, vc fresh-keeping, humidity regulation fresh-keeping, biological fresh-keeping and the like. The fresh-keeping technology of the tidying refrigerator can be divided into five types according to the technical characteristics: temperature control, humidity control, microbial control, gas control, and induction technology. Among them, the temperature control type refrigerator, the ice temperature fresh-keeping refrigerator has a wide development prospect. The manufacturing principle of a foreign ice temperature fresh-keeping refrigerator is as follows: the cold air flow firstly cools and freezes the freezing chamber and then distributes the cooled and frozen air flow to the ice-warming chamber and the refrigerating chamber. The refrigerator structure can achieve accurate ice temperature control and fresh keeping. However, this reduces the moisture content of fresh food such as fruits and vegetables during storage, resulting in a reduction in the quality of the food. The research department of the fruit products of the Japan agricultural and forestry aquatic products provinces develops a novel refrigeration device which can store the fruit products in a low-temperature and high-humidity environment and prolong the fresh-keeping period of the fruit products. This novel refrigeration plant adopts cold and hot radiation formula cold-stored, and the cold water circulation coil pipe is arranged to the wall, radiates the cooling between food and the cold wall, can make walk-in temperature and relative humidity maintain certain level through adjusting the device, forms high humidity, low temperature, windless food storage environment. In our country, the humidity control type fresh-keeping technology is gradually developed, and technologies such as silicon filter membrane moisturizing, moisture permeable fresh-keeping plates, moisturizing anti-freezing walls, humidity adjusting fresh keeping, anhydrous humidification, return air defrosting humidification and the like are developed. These humidification techniques can be divided into passive freshness preservation using a breathable moisturizing material and active freshness preservation using a water tank for humidification according to principles. In the humidification technologies, active humidification of a water tank is adopted, equipment such as the water tank, an atomization device and a fan need to be added, meanwhile, the added equipment can occupy a certain storage space, and passive humidification and fresh keeping of a breathable moisture-keeping material can cause surface condensation in the storage process, so that the fresh-keeping effect is reduced.

Fluid ice refers to an aqueous solution containing suspended ice crystal particles. Wherein the diameter of the ice crystal particles is 0.25-0.50 mm. The latent heat of the ice is 335kJ/kg, the specific heat capacity of the water is 4.2kJ/kg, and under the condition of the same temperature and flow, the cold-carrying energy of the flow ice with the ice content of 5-20 percent is 1.8-4.3 times that of the cooling water. At present, the fluid ice is widely applied to the fields of building air conditioners, production lines of cold and aquatic products for processes, quick precooling of picked fresh fruits and vegetables and the like.
