DOUBLE CHAMBER DRIER Russian patent published in 2008 - IPC F26B20/00 

FIELD: drying equipment.

SUBSTANCE: in double chamber drier, which contains two serially connected chambers, one of which is made as convective, the novelty is that as the other chamber conductive-convective chamber is used, at that convective chamber of rectangular section is installed vertically above conductive-convective chamber, inside convective chambers there are hingedly installed above each other inclined perforated trays with openings, which are made at the angle in direction of transverse blowing of product layer, which are alternately fixed to its opposite lateral walls and are made with the possibility of incline angle regulation, under every tray inertial mesh accumulator is installed, inside space of double-body casing of conductive-convective chamber spiral and rectangular partitions are installed that form heat exchange channels for coolant motion, and in top part of convective chamber nozzle is arranged for removal of spent coolant with mesh for trapping of powdered fractions of dried product, which is connected to heat exchange channels of conductive-convective chamber, on horizontal shaft of which two tape spirals are serially installed with different diameter and opposite coiling, also mixing device of frame type, which represents several oval-shaped flat plates, which are installed at the angle to casing axis and fixed in holders, and spiral screw, at that lower part of conductive-convective chamber casing in zone of spiral screw and mixing device of frame type location is made as perforated, and double-body casing of conductive-convective chamber in zone of tape spiral location is equipped with nozzle for removal of condensate.

EFFECT: provision of drying process intensification.
