Publication number: 20230076213Abstract: A continuous dryer heat exchanger device has a plurality of heat exchanger units. Waste air of an associated dryer section of the associated continuous dryer is guided through an individual heat exchanger unit and contaminants from the waste air are deposited in the heat exchanger unit. A cleaning device for cleaning the continuous flow heat exchanger device of the contaminants is thereby provided, which cleaning device has a plurality of cleaning units. An associated heat exchanger unit is to be cleaned by means of the individual cleaning unit. A switching device is provided, by means of which the cleaning units are to be switched in series one after the other.Type: ApplicationFiled: September 7, 2022Publication date: March 9, 2023Applicant: STELA Laxhuber GmbHInventors: Michael Stummer, Thomas Christian Laxhuber

Patent number: 10634429Abstract: A continuous-flow dryer for drying a material by hot air is provided with a first and a second section, through which the material flows successively in a transport direction. It includes a fresh air supply device, an exhaust air recirculation device for removing exhaust air and for recirculating exhaust air as supply air, and a heat exchanger, through which fresh air and exhaust air are led, for transferring waste heat of the exhaust air into the fresh air. With the exhaust air recirculation device a first part of the exhaust air is removed from the first section and recirculated directly into the first section. Furthermore, a second part of the exhaust air is removed from the first section, led through the heat exchanger, and recirculated as supply air into the first section. The fresh air supply device supplies fresh air as supply air into the second section.Type: GrantFiled: April 24, 2018Date of Patent: April 28, 2020Assignee: STELA Laxhuber GmbHInventors: Tobias Latein, Thomas Christian Laxhuber

Patent number: 10619923Abstract: A continuous-flow dryer for drying a material by hot air is provided with a first and a second section, through which the material is passed successively in a transport direction. It includes a fresh air supply device, an exhaust air recirculation device for removing exhaust air and recirculating it as supply air, and a heat exchanger, through which fresh air and exhaust air are led, for transferring waste heat of the exhaust air into the fresh air. With the exhaust air recirculation device a first part of the exhaust air is removed from the first section and recirculated as supply air directly into the first section. Furthermore, a second part of the exhaust air is removed from the first section, led through the heat exchanger, and recirculated as supply air into the first section. The fresh air supply device supplies fresh air as supply air into the second section.Type: GrantFiled: April 24, 2018Date of Patent: April 14, 2020Assignee: STELA Laxhuber GmbHInventors: Tobias Latein, Thomas Christian Laxhuber

Publication number: 20190041134Abstract: The invention relates to a continuous flow dryer (10) for drying a material (14) by means of hot air (24), comprising a first and a second section (20, 22), which in a transport direction (18) are successively passed through by the material (14), and which in terms of flow are separated to a great extent. The invention is characterized in that a fresh air supply device (28) for supplying fresh air (26) as first infeed air (32) into the first section (20) is provided, an exhaust air recirculation device (44) for removing exhaust air (40) from the second section (22) and for recirculating exhaust air (40) as second infeed air (42) back into the second section (22) is provided. Furthermore, a heat exchanger (58) is provided, through which the fresh air (26) on the one hand and the exhaust air (40) on the other hand are guided, for transferring waste heat (62) of the exhaust air (40) into the fresh air (26).Type: ApplicationFiled: February 1, 2017Publication date: February 7, 2019Applicant: STELA Laxhuber GmbHInventors: Thomas Christian Laxhuber, Tobias Latein
