Patent number: 11964446Abstract: A continuous production system continuously produces a product from a raw material powder. The system includes a first processor that performs a first process on the raw material powder, a second processor that performs a second process on the powder on which the first process has been performed by the first processor, and a test chamber through which the powder being sent from the first processor to the second processor passes. A cleaner blows gas from an inlet side opening formed in the inner face of a channel connected to the test chamber from the first processor on the downstream side of an inlet side gate valve for opening and closing the channel toward a direction to form a swirling flow along the inner face of the channel.Type: GrantFiled: December 19, 2019Date of Patent: April 23, 2024Assignee: MITSUBISHI CHEMICAL ENGINEERING CORPORATIONInventors: Akihiro Matsuki, Nobuhiro Tanaka, Katsuhiro Murata, Hironobu Takeda

Patent number: 11944590Abstract: A continuous manufacturing system continuously manufactures a product from a powder of a raw material. The system includes a first processing device that performs first processing on the powder of the raw material; a second processing device that performs second processing on the powder on which the first processing device has performed the first processing; and an inspection and sorting device including an inspection chamber into which powder sent from the first processing device flows. When a prescribed amount of the powder has accumulated in the inspection chamber, the inspection and sorting device inspects the powder inside the inspection chamber after blocking a path connecting the first processing device to the inspection chamber. When the inspection ends, the inspection and sorting device removes the blocking after discharging the powder from inside the inspection chamber.Type: GrantFiled: February 22, 2018Date of Patent: April 2, 2024Assignee: MITSUBISHI CHEMICAL ENGINEERING CORPORATIONInventors: Akihiro Matsuki, Nobuhiro Tanaka, Katsuhiro Murata, Hironobu Takeda

Patent number: 11675343Abstract: A production system for producing products from raw materials by a production process with several steps has a number of production facilities that perform the steps and a control device. The control device determines a control target value by referring to information about group combinations specified in accordance with the relative merits of the manufacturing condition routes followed by respective lots during the production process. The routes are respectively set for a number of groups that are classified on the basis of raw material properties formed of a combination of property items of one or more types of raw materials. The relative merits of the routes are determined on the basis of quality items of the lots, classified for inter-step combinations of groups, which are classified on the basis of manufacturing conditions at the steps.Type: GrantFiled: March 19, 2019Date of Patent: June 13, 2023Assignee: Mitsubishi Chemical Engineering CorporationInventors: Kouji Kawano, Akihiro Matsuki
