FIELD: power engineering. ^ SUBSTANCE: multi-level chamber of infrared drying of vegetable products comprises a body with air ducts under a distribution grid, where filters, fans and heaters are serially installed, and a gate valve in the form of a window, at the same time height of each level formed by parallel mounted detachable trays, having a perforated bottom, is 2.3-2.5 times higher than the distance from the level tray to the row of evenly distributed infrared radiators arranged in the form of quartz tubes with a ceramic functional shell, the central spiral of which is connected to a source of power supply. The novelty is the fact that between infrared radiators in each row closed by reflectors at the ends there are de-energised quartz tubes installed with ceramic shells, which are arranged in the range of radiation with wavelength from 1.5 to 3.0 mcm, besides, the ratio of the infrared radiator installation height above the level tray to the pitch of their distribution in a row is set in the range of 1.1-1.2. ^ EFFECT: invention shall provide for automatic levelling in volume of heat energy levels, at the same time consumed power is reduced. ^ 2 dwg |
