Abstract: A cooking appliance for commercial kitchens has a fat collection device with at least one fat collection container, at least one fat extraction line, at least one suction pump and at least one fat discharge line. The fat extraction line extends from the fat collection container to the suction pump. The suction pump conveys a fat-water mixture via the fat extraction line into the fat discharge line. A cleaning device is provided which conveys water at least via the fat extraction line and the fat collection container into a cooking chamber outlet of the cooking appliance.

Abstract: A hot wire device and method for depositing semiconductor material onto a substrate in a deposition chamber in which the ends of at least two filaments are clamped into a filament holder and heated by supplying current, wherein a voltage for generating an electrical current is applied in temporal succession to filaments made of differing materials so that a number of differing semiconductors corresponding to the number of consecutively heated filament materials can be consecutively deposited onto the substrate without opening the chamber.
