Publication number: 20160131426Abstract: A drying device 1 is an airflow continuous drying device, and includes a granulated substance introduction portion 11, a dry process portion 12, and a product ejection portion 13. The granulated substance introduction portion 11 is a stainless steel pipe 21, including a granulated substance inlet 22, into which granulated substances are put, and a hot air inlet 23, into which high-pressure hot air is supplied. The dry process unit 12 includes a loop pipe 25, which is made by winding a stainless steel pipe. The loop pipe 25 is arranged laterally in the horizontal direction, and is able to dry granulated substances in a highly efficient manner without turning the substances into powder. The product ejection portion 13 includes a cyclone collector 26, where the granulated substances are collected after being dried through the loop pipe 25.Type: ApplicationFiled: June 25, 2014Publication date: May 12, 2016Inventors: Yasutoyo FUSEJIMA, Hirotsune YASUMI, Shigemi ISOBE, Norikazu SAITOU, Takashi TERADA, Naoko MIZUNO

Patent number: 8807065Abstract: In a pan coating apparatus including a rotary drum which rotates about a horizontal rotation axis, an air supply chamber having a larger sectional area than that of an opening portion is arranged on a front stage with respect to the front-surface opening portion of the rotary drum. The air supply chamber is formed in a chamber door attached to a front of a casing, and has one end side communicating to the opening portion and another end side connected to an air supply duct via an air supply hole. The air flowing into the air supply chamber from the air supply duct is reduced in flow rate in the air supply chamber and supplied from the opening portion into the rotary drum with the air flow thereof in a stable state.Type: GrantFiled: October 9, 2009Date of Patent: August 19, 2014Assignee: Freund CorporationInventors: Yasutoyo Fusejima, Takuya Nakamura, Takashi Terada, Shigemi Isobe

Publication number: 20140000510Abstract: A spray gun (31) is attached to a multi-function unit (32) movable in a horizontal direction and a perpendicular direction. The spray gun (31) is mounted to a support holder (33), and the support holder (33) is connected to a support arm (35) of the multi-function unit (32). The support arm (35) is attached to a unit cover (36) which is openable/closable with respect to a casing (2). The support holder (33) and the support arm (35) can hide and house a liquid hose and an air hose therein so that the hoses and the like are arranged in an apparatus in such a state as to be completely free from being exposed. An installation position of the spray gun (31) can be finely adjusted by the multi-function unit (32) during a coating process, thereby enabling a control for keeping constant distances between tablet surfaces and the spray gun (31).Type: ApplicationFiled: September 6, 2013Publication date: January 2, 2014Applicant: FREUND CORPORATIONInventors: Yasutoyo FUSEJIMA, Takuya NAKAMURA, Takashi TERADA, Shigemi ISOBE

Patent number: 5531826Abstract: The rotary drum has a cylindrical portion (tubular body portion) formed therein with vent holes. An annular duct is disposed at the outside of the cylindrical portion of the rotary drum in a manner to surround the cylindrical portion. This annular duct is provided with a gas supply duct and an exhaust duct. In the annular duct, partition walls define a vent path, in which the drying gas which has been supplied from the gas supply duct flows through an accumulated layer, and thereafter, flows to the exhaust duct. The direction of flow of the drying gas in the vent path is changed over by gas supply-exhaust changeover dampers.Type: GrantFiled: October 7, 1994Date of Patent: July 2, 1996Assignee: Freund Industrial Co., Ltd.Inventors: Yasutoyo Fusejima, Tsugutoshi Yamada, Shuri Yamada, Narimichi Takei
