It has a taper angle (θ) of about 20° to expand the diameter of the lateral roots. The nozzle hole diameter (d) is set to 6φ, 8φ, 10φ, etc. Under these conditions, a string-like intermediate product (7) with a constant cross-sectional shape was obtained from the nozzle hole [81°, and then this intermediate product (7) was cooled to room temperature and solidified, and then a Fura-Lido sword-shaped product was obtained. A cylindrical product with a thickness of 1 to 20% is crushed using a crusher (not shown). In this case, the following results were obtained.

Since it is a method of thinning, it is possible to easily stabilize the grains by determining the length of the shredder, and also to eliminate the need for material D. By using cooling assimilation and shredding, continuous production can be carried out and productivity can be greatly improved.Furthermore, since it is a kneading method, it is possible to use This method has the advantage that it can sufficiently permeate the material, increase the strength of the material, and improve the uniformity of the material compared to conventional methods.
