Patent number: 8733552Abstract: An integrally-rotating cylindrical sieve 1 includes a hollow rotating shaft 2, which a driveshaft 21 is inserted into and fixed to, support members 3 radially extended from the rotating shaft 2, a cylindrical sieve body 4 made from a thin plate with a large number of apertures 5 formed therein, such as punching metal, and coupled with the support members 3, and sieve frames 6a and 6b attached to axial ends of the sieve body 4. The rotating shaft 2, the support members 3, the sieve body 4, the sieve frames 6a and 6b, and the driveshaft 21 are coaxially rotated together. The sieve body 4 is a cylindrical corrugated plate having wave crests and wave troughs arranged along its circumference and has a large number of apertures 5 formed in the corrugated plate. This arrangement improves the sieving efficiency of the granular material and effectively prevents potential destruction and cracking of the granular material, thus enhancing the commercial value of the sieved granular material.Type: GrantFiled: May 31, 2010Date of Patent: May 27, 2014Assignee: Tsukasa Co., Ltd.Inventor: Yasuhiro Ikeda

Patent number: 7534074Abstract: In order to prevent the contamination of particulates such as food material particulates, facilitate maintenance, and to enhance the process sealing accuracy, a flow path switchover device is presented. The device of the present invention has a tube assembly including first and second main tube members and a branch member. The first and second main tube members are interconnected via a first ring member. The first main tube member and the branch member are interconnected via a second ring member arranged at a preset angle with the first ring member. A metal changeover damper supported on a rotating shaft swings between the first and second ring members and accordingly blocks and seals either the connection between the first main tube member and the second main tube member or the connection between the first main tube member and the branch tube member, while allowing the other connection.Type: GrantFiled: July 27, 2007Date of Patent: May 19, 2009Assignee: Tsukasa Co., Ltd.Inventor: Fumio Kato
