Publication number: 20200114365Abstract: A rice husker includes a pair of husking rolls. One of the pair of husking rolls is attached to a main shaft and the other of the pair of husking rolls is attached to an auxiliary shaft movable to be close to and away from the main shaft. The rice husker includes abnormality determination means. The abnormality determination means determines that the husking rolls fail to work normally when vibrations having a preset intensity larger than the preset intensity are successively detected by a vibration sensor until a certain time elapses. The certain time is from the start of a husking action to disappearance of distortion on a surface of the husking roll. The vibration sensor is provided on at least either of bearing units of the main shaft and the auxiliary shaft. The vibration sensor detects vibrations occurring due to the husking action by the pair of husking rolls.Type: ApplicationFiled: December 25, 2017Publication date: April 16, 2020Applicant: SATAKE CORPORATIONInventors: Takeshi FUKUMORI, Sumio TAGAWA, Minoru KOREDA

Patent number: 10578557Abstract: An object of the present invention is to improve the quality level discrimination accuracy of the grain G by a grain quality level discrimination device. The device includes an optical unit 3 that emits light to the grain G, receives reflected and/or transmitted light from the grain G by a photosensor, and obtains information for discrimination of the quality level of the grain G from the upper and lower surface side of the grain G, and a quality level discrimination unit 7 that discriminates the quality level of the grain G on the basis of the information. The information on the upper and lower surface sides can be acquired by one optical unit at the same time so that the divergence therebetween due to the displacement or variation of the attitude of the grain G can be avoided. The reference plate for the correction of the information is placed outside of the moving path of the grain G to prevent it from soiling or damaging. Thus the deterioration of information can be avoided.Type: GrantFiled: December 18, 2015Date of Patent: March 3, 2020Assignee: SATAKE CORPORATIONInventors: Hiroki Ishizuki, Akira Eto, Takahiro Doi, Hiroaki Takeuchi

Patent number: 10525508Abstract: The present invention has an object to provide a blowing apparatus wherein a piezoelectric element is unlikely to cause insulation deterioration leading to burnout during use of the blowing apparatus. The blowing apparatus of the present invention blows compressed gas supplied from a compressed gas supply unit through a nozzle hole of a nozzle unit by opening a piezoelectric valve. The blowing apparatus comprises a humidity sensor detecting a humidity of the compressed gas inside a flow path unit, and a humidity control unit comparing a detected value of the humidity detected by the humidity sensor with a set value. If the humidity of the compressed gas inside the flow path unit detected by the humidity sensor is equal to or greater than the set value, the humidity control unit replaces the compressed gas inside the flow path unit with the compressed gas whose humidity is less than the set value and which is supplied from the compressed gas supply unit, before starting to use the blowing apparatus.Type: GrantFiled: September 5, 2016Date of Patent: January 7, 2020Assignee: SATAKE CORPORATIONInventors: Takafumi Ito, Sze Keat Chee

Patent number: 10136665Abstract: Raw material rice (brown rice and partially-milled rice) is subjected to a preliminary pressurized steam-boiling process to form an alpharized layer on the surface of the raw material rice, and then a moisture adding process is performed. Since the surface of the raw material rice is alpharized to become stiff with the preliminary pressurized steam-boiling process, even rapid moisture addition does not cause a crack in the raw material rice. Therefore, water absorption can be quickly achieved to a target moisture content, thereby reducing a moisture adding time. Also, with no crack, quick-cooking rice with an excellent outer appearance of rice as a product and without a drain of nutrients in rice grains at the time of rice cooking.Type: GrantFiled: June 11, 2010Date of Patent: November 27, 2018Assignee: SATAKE CORPORATIONInventors: Takeshi Fukumori, Shigeharu Kanemoto, Keishi Wakabayashi
