構造となっている。The cylindrical member 12 is provided with low temperature helium supply systems 13a and 13b for supplying and discharging low temperature helium as a cooling source in the container, and the cooling surface 11 is supplied with the low temperature helium. It is cooled to a temperature at which liquid hydrogen can be precipitated as solid hydrogen. In addition, the surfaces other than the cooling surface 11 are formed by a heat insulating structure using a heat insulating material or a vacuum heat insulating structure so that solid hydrogen is not deposited.

Radially provided at the tip of the cutting blade, the cutting portion 21a at the tip of the cutting blade is formed so as to rotate in a plane parallel to the cooling surface 11. In this example, four cutting blades 21 are provided, but the number of cutting blades can be arbitrarily selected from one or more according to the required capacity, and the shape is also arbitrary. On the other hand, it is also possible to provide a receding angle with respect to the rotation direction without arranging radially in the radial direction.

きる。Further, the clearance between the cooling surface 11 and the cutting portion 21a needs to be made as small as possible in order to improve efficiency, and it is desirable to adjust it to about 0.1 mm. The clearance can be adjusted by first adjusting the orthogonality between the cooling surface 11 and the rotating shaft 22, and then adjusting the distance between the cooling surface 11 and the rotating shaft 22 by using a normal clearance gauge or a flat plate having a predetermined thickness. Adjustment of this orthogonality and adjustment of the interval are
Similar to general leveling adjustment and height adjustment, it is possible to perform extremely easily with a simple structure by using a screw or the like.

Since no processing precision is required, manufacturing is easy, and assembly work and maintenance work can be performed easily, so that the equipment cost and maintenance cost required for producing slush hydrogen can be significantly reduced.
Further, since large parts can be easily manufactured and easily adjusted, the size of the device can be easily increased, and a large amount of slush hydrogen can be efficiently manufactured at low cost.

Also, the cutting blade is
