Patent number: 11414638Abstract: A portable bioreactor is provided for driving displacement of at least one stirring sleeve relative to at least one tube cassette in a first direction and includes a machine frame unit and a first elevator. The first elevator includes a first linear movement module, a first transmission module, and a first turning module. The first linear movement module includes a first slider which is slidable on the first guide rail in the first direction between a first top position and a first bottom position. The first turning module is coupled to the first slider through the first transmission module so as to permit turning of the first turning module to be translated by the first transmission module into linear sliding movement of the first slider at a varying speed.Type: GrantFiled: February 27, 2020Date of Patent: August 16, 2022Assignee: GENEREACH BIOTECHNOLOGY CORPORATIONInventors: Wen-Shan Yang, Ching-Ko Lin, Fu-Chun Li, Pin-Hsing Chou, Yun-Lung Tsai, Pei-Yu Lee, Hsiao-Fen Chang

Patent number: 9907117Abstract: The present disclosure relates to a heating device and a biochemical reactor having the heating device. The heating device includes an upper plate, a lower plate, a middle plate, and an electric heating element. The upper plate has an upper heating hole, an upper receiving hole, and an upper conductive layer. The lower plate has a lower heating hole, a lower receiving hole, and a first lower conductive layer. The middle plate is disposed between the upper and lower plates and has a middle heating hole and a middle receiving hole. The upper, middle and lower receiving holes are connected together to form a receiving through hole. The electric heating element is disposed in the receiving through hole and has two terminals connected to the upper conductive layer and the lower conductive layer, respectively.Type: GrantFiled: June 5, 2015Date of Patent: February 27, 2018Assignee: Genereach Biotechnology Corp.Inventors: Chen Su, Hsiao-Fen Chang, Pei-Yu Li, Yun-Lung Tsai, Ching-Ko Lin, Wen-Hao Cheng, Pin-Hsing Chou
