Problems solved by technology

[0004] At present, ice temperature storage is mostly transformed from the original cold storage by adding circulating fans and cold storage plates. The uniformity of the flow field in the storage is poor, and there are dead angles in temperature and wind speed, which makes it difficult to meet the requirements of ice temper

Embodiment Construction

[0024] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0025] The schematic diagram of the ice temperature storage warehouse of the present invention is as follows figure 1 with figure 2 As shown, it includes a refrigeration system and a library body, and a library door 9 is provided on the library body. The library body includes a bottom insulation layer 8, an outer insulation storage body 1 connected with the bottom insulation layer 8, and an inner non-insulation storage body 4. There is an air interlayer 2 as the return air passage between the inner non-insulation storage body 4 and the outer insulation storage body 1. In the refrigeration system, multiple parallel cooling fans 3 that work alternately or defrost are installed in the outer storage. In the air interlayer on the top of the body, a top air supply orifice 6 is arranged inside the inner storage body, and a porous cotton is arranged on the top air su...

Abstract

The present invention discloses an ice-temperature vault. The aim of the invention is to provide an ice-temperature vault which has the advantages of high-precision control, uniform wind speed field in the vault, uniform temperature field in the vault, and satisfaction to the requirement of ice-temperature storage. The vault body comprises a base layer heat insulation layer, an outer heat insulation vault body and an inner non-heat-insulation vault body which are connected with the base layer heat insulation layer. An air interlayer is provided between the inner non-heat-insulation vault body and the outer heat insulation vault body. A plurality of air coolers which are connected in parallel for alternately operating or defrosting are installed in the air interlayer at the top part of outer vault body. A top air supply aperture plate is provided in the inner vault body. A static pressure box layer is formed between the top air supply aperture plate and the inner non-heat-insulation vault body. The periphery at the base part of inner non-heat-insulation vault body is provided with a plurality of return air grilles. A temperature sensor is respectively installed at the lower part of static pressure box layer and at the return air grilles. The temperature in the ice-temperature vault is stable. The speed field and temperature field are extraordinarily uniform. The defrosting does not affect the temperature in the vault. The ice-temperature vault has high control precision. The temperature fluctuation of hollow vault does not exceed +/- 0.3 DEG C.

Description

Technical field [0001] The invention relates to an ice temperature storage warehouse. Background technique [0002] Hyo-on storage is the storage of food in the range below 0°C to the respective freezing point. It is non-freeze storage and is the third generation of fresh-keeping technology after refrigeration and CA storage. Long-term applications have shown that it is impossible to achieve long-term storage of food due to the rapid ripening and corruption of food during cold storage; although freezing can store food for a long time, due to the death of food cells, juice loss occurs during thawing, and the original food cannot be maintained. There is a flavor. Ice temperature storage can effectively maintain the inherent flavor and freshness of ripe fruits and vegetables for a long time, so it can increase the value of commodities. Ice temperature technology is widely used in the fields of agriculture, storage, animal husbandry, aquatic products storage and transportation, and m...
