FIELD: engines and pumps.

SUBSTANCE: proposed device comprises drying chambery communicating with pneumatic system and consisting of top and bottom sections arranged on the frame. Aforesaid sections have their open parts arranged in opposition. Heaters are arranged between housings of every section. Movable cover is arranged between sections for them to be sealed. Vessels intended for cyclic dynamic feed of compressed air into detachable pneumodynamic chambers are arranged on the cover to move from one section to another. Aforesaid pneumodynamic chambers are rigidly fitted onto sleeves arranged on the surface of every vessel. There are fans to uniformly circulate hot air inside every section that can be turned off after opening the sections. Aforesaid chambers represent petal-type nozzles consisting of tip outer threaded rings 16 with carving, outer 17 and inner 18 rings. Ring 21 with fasteners for lugs 22 and plates 23 are fastened, with the help of screws 19 and washers 20, onto every outer 17 or inner 18 ring of the nozzle, and on top outer ring 16. Four vertical plates 23 are arranged between ring pairs. Note here that plate 23 can move in ring 21 in every upper of ring pairs and in top outer threaded ring 16 of plate 23. Every lower ring 21 with fasteners lugs and plates is rigidly fixed with the help of pins 24. Four lugs 22 are arranged to move in ring pairs 21 via push-rods 28. Pneumodynamic chamber base accommodates platform 29 supporting aforesaid chamber to rule out sliding of treated fur skin 31. Collar 34 is tightened by the screw 35. Note that half nut 36 is attached to foresaid platform 29 for pneumodynamic chamber to be fastened to the device. Rubber gasket 39 is arranged between aforesaid half nut and platform. Rubber seal 40 is fitted into half nut 36 for tightness purposes. Bellow 41 is arranged inside afore described chamber for compressed air to be fed therein in cycles. Threaded plug 42 is fitted on one end of aforesaid bellows 41 for it to be jointed to top outer ring 16. Other end of bellows is arranged on nozzle of platform 29.

EFFECT: higher efficiency.
