TECHNICAL FIELD
[0001] The utility model belongs to the technical field of freezing system, concretely relates to an integrated low-temperature quick freezing and storage device. BACKGROUND
[0002] The best preservation condition of biological samples (plasma) is frozen preservation. In blood station operation, when blood is separated into plasma and red blood cells, the plasma needs to be frozen within six hours. The national blood management standard requires that the central temperature of the plasma should reach -30 DEG C within one hour during freezing. After blood is separated from the body, the plasma is separated from the red blood cells, and the plasma is rapidly cooled to below -30 DEG C. The existing plasma flat quick freezer is not suitable for long-term storage of frozen objects. The frozen objects must be removed immediately after the set time and transferred to a storage refrigerator for frozen preservation. The frozen plasma must be removed immediately and cannot be used as a storage refrigerator.
[0003] Chinese patent application No. 202223453279.8 discloses a quick freezing device and a quick freezing and ultra-low temperature preservation freezing system, which comprises a mounting frame and a plurality of cold storage units arranged on the mounting frame. The cold storage unit comprises an upper cold storage plate, a freezing clamp plate and a lower cold storage plate. The space between the upper cold storage plate and the lower cold storage plate is a clamp space. The freezing clamp plate is located in the clamp space and can move along the clamp space. The inside of the upper cold storage plate and the lower cold storage plate is a cooling zone. The cooling capacity of the cooling zone is provided by a water chiller. The utility model provides a quick freezing device and a quick freezing and ultra-low temperature preservation freezing system, which solves the problem of high energy consumption of the existing quick freezing refrigerator and the need to transfer the quick frozen samples to a storage refrigerator, which is inconvenient to operate.
[0004] In the above-mentioned disclosed patent, 1. It belongs to a split type. The ultra-low temperature quick freezing water chiller and the quick freezing device are two independent units, which have requirements for on-site installation conditions, occupy a large space, and are not flexible in installation space. 2. The water chiller has large power and needs to provide 380V power. Most of the on-site uses 220V power supply, which cannot drive the device to operate normally. 3. After the quick freezing time is over, the quick freezing space is occupied, and the quick frozen samples need to be transferred to other low-temperature storage equipment for storage, so that the quick freezing of the next batch of plasma can be carried out.
