AUTONOMOUS DEVICE FOR DRYING OF VEGETATION RAW MATERIALS Russian patent published in 2012 - IPC F26B9/06 F26B20/00 

FIELD: power engineering.

SUBSTANCE: autonomous device for drying of vegetation raw materials comprises a furnace 1, an electronic control unit 5, a drying chamber 13 with a tray 14 arranged for it for raw materials, an air blower 9 with air ducts, a Stirling engine 2, comprising a shaft 7, hot and cold cavities. The hot cavity is connected with the furnace 1, and the shaft 7 is mechanically connected with the generator 6, electrically connected via the electronic control unit 5 with the electric motor 8 of the air blower 9 drive, which by air ducts 10 and 12 via air heating pipes 11 arranged in the furnace is connected with the drying chamber 13, the tray 14 of which is connected to a vibrator 15, joined electrically via the electronic control unit 5 with the generator 6. The drying chamber 13 and the furnace 1 are equipped with temperature sensors 16 and 17 joined with the electronic control unit 5, besides, between the furnace 1 and the hot cavity of the Stirling engine 2 there is a gate 3 with a drive 4, connected via the electronic control unit 5 with the generator 6. The generator 6 excitation system is connected with the electronic control unit 5.

EFFECT: simplification of design and improved quality of drying.
