The rice-powder paid to attention in Japan, because the various food made by rice-powder. But, conventional method of manufacturing rice-powder generates heat when crushing of rice. One the other hand, the pressure vessel of oval structure for manufactured rice-powder using underwater shock wave has been developed in Okinawa National College of Technology. The merits of this system manufacture rice-powder without heating.

But, the efficiency of this system is low. Therefore, in this paper, we propose new design of pressure vessel for the highly effective rice-powder manufacturing. To design a new pressure vessel, it is clear that the performance of the oval structure pressure vessel. And, we design and manufacturing new pressure vessel for the highly effective rice-powder manufacturing.
