4th, the first support shaft and first are supported by axis connection by clutch.
5th, it is passed through liquid nitrogen toward the quick-frozen interior of Liquid Nitrogen Cooling Room and aquatic products is freezed, in this process：
Across the sea due to hull floating, shaking can constantly be generated in wave effect pontoon；And during hull shakes,
Clump weight can swing back and forth around the first support shaft（Around the first support shaft clockwise oscillation or counter-clockwise swing）.
Since connecting bushing is rotatably arranged on by unilateral bearing in the first support shaft, with unilateral bearing around the first support
Axis can be freely rotated clockwise, and for locking in the counterclockwise direction：In clump weight around the first support shaft up time
When needle is swung, the first support shaft does not rotate；When clump weight is around the first support shaft counter-clockwise swing, clump weight will pass through company
Extension bar, connecting bushing and unilateral bearing drive the first support shaft to rotate counterclockwise, and then pass through driving gear and driven gear band
Dynamic net cylinder of placing is around the second horizontal shaft rotation；
In addition, due to driving gear outer diameter be much larger than driven gear outer diameter, in this way in clump weight around the first support shaft back and forth
During swing, placement net cylinder will be driven constantly to be rotated with certain speed around the second horizontal shaft；Placing net cylinder rotation
During turning, the aquatic products placed in net cylinder will constantly roll, and freeze uniformity to improve aquatic products, improve aquatic products
The whole freezing efficiency and freezing quality of product.
The automatic turning liquid nitrogen quick cooler of our embodiment directly applies on hull, can utilize floating across the sea
The characteristic that can shake of hull, place net cylinder rotation to drive, and then improve aquatic products and freeze uniformity.
On the other hand, the automatic turning liquid nitrogen quick cooler of our embodiment is not necessarily to additional power-equipment and the energy（Example
Such as motor and electric energy）Carry out electronic placement net cylinder rotation, can effectively reduce the energy consumption of automatic turning liquid nitrogen quick cooler, this is for ship
The energy is carried inherently for very limited situation, is meaningful.
In addition, in the 5th step, when one of spin refrigeration device freezes in liquid nitrogen frozen room, liquid nitrogen frozen
Another spin refrigeration device of outside can carry out the operation of second step, and aquatic products to be frozen are packed into and place net cylinder
It is interior, to improve whole refrigeration operation efficiency.
6th, after the completion of the aquatic products freezing on the spin refrigeration device in liquid nitrogen frozen room, liquid nitrogen frozen will be located at
Indoor spin refrigeration device is moved to the outside of Liquid Nitrogen Cooling Room；
Then, another spin refrigeration device is moved to by main guide rail in liquid nitrogen frozen room, aquatic products is freezed.
