AI Technical Summary
In existing low-temperature freezers, the design of the baskets is not convenient for placing large objects during storage, and manual handling can easily cause frostbite, making operation inconvenient and dangerous.
The system uses a drive assembly to rotate the lead screw, which in turn raises and lowers the basket by means of the lead screw principle. Combined with the volume changes of the piston head and the liquid storage tube, the liquid nitrogen level is controlled to decrease, thus improving operational safety and convenience.
This system enables stable raising and lowering of the basket, reducing the risk of frostbite to workers from liquid nitrogen and improving the safety and convenience of the storage process.
