Description

Cold storage

Technical Field

The application relates to the technical field of refrigeration houses, in particular to a refrigeration house.

Background

At present, some frozen objects need to be manually transferred to a refrigeration house with higher temperature for storage after being frozen in the refrigeration house with lower temperature. In the transferring process, the frozen object can be exposed to the room temperature environment, the risk of temperature return exists, manual operation is performed in the transferring process, the working efficiency is low, and the risk of frostbite exists.

Taking frozen matter as plasma for example, according to the quick freezing requirement of the technical operating procedure of blood station, the central temperature of the freshly prepared plasma should be reduced to below-30 ℃ within 60 minutes.

Plasma quick-freezing mainly comprises air-cooled quick-freezing, contact quick-freezing, mixed quick-freezing combining air cooling and contact, and the like according to freezing modes; according to the structure of the carriage body, the carriage body is divided into a horizontal carriage body, a vertical platform type and the like. Different quick-freezing modes and different equipment manufacturing costs, the time required by freezing and the quality of the frozen blood plasma are different.

The blood station and hospital in China basically adopt an air-cooled blood plasma instant freezer. The forced air cooling quick freezing is to achieve the purpose of quick freezing in a quick freezing cavity in a low-temperature air forced convection blowing mode. In addition, freezing plasma with a low temperature refrigerator can also be regarded as air-cooled quick freezing with a heat transfer form of natural convection heat transfer.

The contact type plasma instant freezer is also called a flat plate instant freezer, plasma is frozen by directly contacting a plasma bag with a cold plate, the contact type plasma instant freezer has good heat transfer effect, low noise and flat plasma bag after quick freezing, and is superior to an air-cooled plasma instant freezer on the whole, and the wide market of the plasma instant freezer is the current development trend.

Because the air-cooled plasma instant freezer and the contact type plasma instant freezer have small freezing capacity (30-50 bags/time) and cannot meet the blood station requirement (particularly under the condition of concentrated blood collection, hundreds of bags of blood are often frozen), part of blood stations carry out plasma quick freezing through the quick-frozen cold storage, the temperature in the quick-frozen cold storage is reduced to-50 ℃, the aim of quick freezing is fulfilled in a low-temperature air forced convection blowing mode, and the plasma is transferred to a common cold storage at-30 ℃ after being frozen.

After being frozen, the plasma quick-freezing refrigeration house needs to be moved to a plasma warehouse at the temperature of minus 30 ℃, the transfer process is manually operated, the working efficiency is low, and the risk of frostbite exists; moreover, the plasma is exposed to a room temperature environment (around 25 ℃) during the transfer process, which causes the risk of rewarming the plasma.
