Inside on the ends of the outer drum 3 on the shaft 2 is rigidly mounted two discs 7 connecting blades 8, made of box-shape with the ribs 9. Discs 7 have openings 10, and the blades of the partition 8 is formed by three rotating cavity 11, which are interconnected by holes (perforation) 12, made in the blade walls 8. The working surface 13 of each blade-partitions 8 in cross section has the shape of a curve of the second order. The rotation of the cavities 11 formed by blades-partitions 8, rigidly connected with the shaft 2, is carried out by means of the actuator 14.

Loading and unloading of the semi-finished product, the fill and drain process solutions and washing water is carried out through the hatch 15.

Installation works as arr is of opsta-partitions 8, facilitate periodic lowering of leather prefabricated in technological solutions and processing occurs.

The working surface 13 of the blade wall 8 when the rotation helps smooth lowering and lifting of the semi-finished product, which excludes its clumping and twisting. Through the holes 10 in the discs 7 and holes (perforation) 12 in blades walls 8 are circulation and discharge of process solutions.

After the end of the loop the drum 3 by means of the actuator 6 and the gear pair 5 and 4 is rotated 180aboutLuke 15 down and is draining technological solutions. At the same time to prevent loss of prefabricated manhole is closed one of the blades partitions. Then the drum 3 is rotated 180aboutLuke 15 up and served water and cleaning materials.

The cycle repeats till complete processing of the semifinished product in various technological solutions.

INSTALLATION FOR LIQUID PROCESSING of RAW hides AND SEMI-finished, containing an outer drum mounted on bearings for rotation on the shaft, placed inside a second drum mounted for rotation and image of the project for a semi-finished product, and dividing the volume of the cavity, mounted on the shaft to provide rotation with a given number of revolutions, and the United disk, characterized in that each blade is made of box-shape with the ribs, and its working surface has the shape of a curve of second order, while the disks mounted on the shaft firmly.
