Latest Patents
Among his latest patents is a capacitive high-frequency drying apparatus. This innovative system is designed for drying moisture-containing materials by utilizing hot air passed through a high-frequency oven. To improve energy utilization, the air is preheated using waste heat from the high-frequency generator. After passing through the oven, the air is then conducted through a heat exchanger to heat water for utility or industrial purposes. Another significant patent is for a drying apparatus specifically for dyeing bobbins in the textile industry. This automatic system allows for the bobbins, which are slipped onto a perforated tube, to be predried with compressed air. The process includes an intermediate drying operation using infrared heaters, followed by final drying capacitively in a high-frequency oven. The tube with the bobbins is transported through the apparatus as a unit by a transporting device.
