gz The invention relates to the fur industry of light industry. A device for drying tubular-shaped fur skins is known. It contains vertical partition walls located in the drying chamber, an air distributor, holders for sandpaper templates, each of which is mounted with the ability to move into the loading zone, fans and air ducts, and vertical partitions divide the case into separate chambers , each of which has one template for the skin, and the heaters and air ducts have U-shaped guides mounted above and below the chambers ij. This structure does not provide uniform drying-straightening of the fur skin, since the templates for the skin contain electric heating elements that do not evenly provide heating temperatures along their entire surface. . Drying and straightening of the fur are made by contact, i.e. the moisture contained in the leather is removed through the fabric itself and thick hair. Thus, the device does not provide the proper quality and leads to an increase in the time of the technological process of drying the delivery of Fur skins. The purpose of the invention is to increase the productivity and quality of the skins. The goal is achieved by the fact that, in a device for drying fur skins of tubular form, containing vertical partitions located in the drying chamber, an air distributor, holders of templates for sandpaper, each of which is mounted so that it can be moved into the loading zone, fans and air ducts opposite to the walls of the drying chamber are rotatable, the template holders are mounted on opposite sides of each wall, while the air distributor consists of two guide plates with L E connected to the ducting and E placed in a drying chamber with counterfield GOVERNMENTAL sides of vertical partitions each template mounted with the possibility of positioning one of its ends on the corresponding slot of one of the guide plates, and the other end is positioned above another slot of the guide plate. Each template has a fitting mounted on one of its ends, and each template holder has a skin lock. FIG. 1 shows the device and the drying of fur skins of a tubular form. The general appearance {in FIG. 2 shows section A-A in FIG. 1 / in FIG. 3 shows a section BB in FIG. 2, A device for drying tubular-shaped fur skins contains a drying heat-insulated chamber 1, air ducts 2. And 3 for passing heated air, located along the inner perimeter of the drying chamber 1 and bounded by vertical partitions 4 and 5 having holes 6 and 7 for air intake, and a guide plate 8, designed so that slots 9 and 10 are formed for air outlet, rotors 11 and 12 of centrifugal fans mounted on opposite sides in ducts 2 and 3, drives 13 and 14 of rotors 11, 12 ,. guide wall 15 with slots 16. Opposite walls 17 and 18 of the drying chamber 1 are pivoted. On opposite sides of each wall 17 and 18 mounted holders 19 templates 20, each holder 19 has a latch 21 and. clip 22 for the pelt. Each template 20 is a hollow frame rule, the contour of which (the outer part) fully corresponds to the contour of the control patterns of the manufacturer. The templates 20 have a nozzle 23 for the entry of warm air into the internal cavity formed between the skeleton of the template and the leather surface of the fur skin 24, dressed on the template 20. The air is removed from the hole 25, which is formed only when the skin 20 is dressed on the template 20. Swiveling walls 17 and 1B have individual drives 26 and 27. The air exchange in the drying chamber 1 is carried out by means of air vents 28 and 29 with the flaps 30 and 31 installed in them. The device operates as follows. Before drying the fur skins 24, the drying chamber 1 is heated. It uses the principle of converting electric energy into heat rotating in a closed heat-insulated air volume by a rotor of a centrifugal fan of certain calculated sizes. In this construction, the fans 11 and 12 are used, performing the heaters function and receiving rotation from the drives 13 and 14. The pre-moistened fur skins 24 are put on the hollow frame patterns 20. For this, the & torus alternately pushes the hollow patterns 20, releasing the holders 19 clamps 21. Then the hollow patterns 20 are returned to their original position.

the holders 19 are fixed by retainers 21, and the skins 24 by clips 22. When the actuators 26 to 21 are turned on, the swing walls 17 and 18 are turned 180 and the hollow patterns 20 with the skins 24 put on them go into the drying chamber 1, and the free patterns 20 mounted on opposite sides of the walls 17 and 18, come out of it.

 in the process of drying the fur skins 24, the heated air passes inside the hollow patterns 20, removing moisture from the skin surface of the skins.

Having blown warm air through the poluy part is achieved due to the orientation of the hollow patterns 20 with skins 24 on them in the direction of the main air flow (shown by arrows), which, the output from the slots 9 and 10 of air ducts 2 and 3, enters the internal cavity of the patterns 20 through inlet 23, passes through it and removes moisture from the skin surface of the skin. Moisture-saturated warm air escapes from the opening 25 of the narrow part of the template and enters the slot 16 of the guide partition 15. The partition separates the pressure part of the drying chamber 1 from the intake: the partition 15 is the discharge, the area below the partition 15 is the intake. The exhaust air is fed back to the air ducts 2 and 3 through the openings 6 and 7 of the vertical partitions 4 and 5. The air exchange in the drying chamber 1 is necessary. Airflows 30 and 31 through the vents 28 and 29 are required.

After the end of drying of one set of: fur skins 24, the swing walls 17 and 18 are again turned 180 and the templates 20 with dried skins are removed from the drying

5 chambers 1, and a new batch of fur skins 24, worn on the patterns 20, is fed to the drying chamber 1 for drying. The dried skins 24 are removed from the patterns 20 after cooling.

0 The proposed device provides for combining the dressing operations of the collars on the templates in one device using the convective method of drying by supplying heated air to the leather of the sandpaper, which improves the quality of the skin and labor productivity.
