DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described with reference to the accompanying drawings. A pair of horizontal rolls each having a rubber ring having an elastic hardness of 40 to 50 degrees fitted on a stainless steel roll supported on a machine frame are described. The opposing elastic rolls 1 and 1 are rotated in contact with each other while being pressed against each other, and their surface speeds are controlled so as to generate a slight speed difference of about 1 to 5 m per minute to constitute a peeling roll 2. I have.

The peeling rolls 2 are vertically connected in one or more stages, and an air pipe 3 is installed at the lower part of the center between the pair of elastic rolls 1.1 of each peeling roll 2 and peeled off. It is formed so as to scatter the skin to the side.

Below the pair of elastic rolls 1.1 of the lowermost peeling roll 2, a pair of brush rolls 4 rotating inward each other are installed facing each other. A mountain-shaped separation guide plate 5 is provided at the lower portion between the four, and the beans and the skin are reliably separated by the rotating action of the brush rolls 4 and the sliding action of the separation guide plate 5. Have been.

Below the pair of brush rolls 4 and the separation guide plate 5, an inclined cylinder 6 having an arc-shaped cross section and a rotatable slightly helical rubber or synthetic resin or the like provided in the inclined cylinder 6 are provided. A skin separating device including the sliding blades 7 is provided, and the skin attached to the beans that have fallen into the inclined cylinder 6 or the skin that has not yet been separated is reliably separated and transported by the sliding sliding action of the sliding blades 7. It is configured to be guided and dropped into a water tank 8 installed below.

In the surface layer of the water tank 8, there is provided a skin removing device comprising a water injection pipe 9 provided on one side, a scraping blade 10 provided on the other side, and a discharge gutter 11 provided on the water tank. A bean carry-out conveyor 12 is provided below the water tank 9 for carrying the settled beans out of the tank.

In the figure, reference numeral 13 denotes a hopper provided above the uppermost peeling roll 2, wherein the degree of pressure contact, the number of rotations and the speed difference of the elastic rolls 1.1 are adjustable, and the type of beans , Size, degree of water immersion, etc. can be appropriately adjusted.

Since the embodiment of the present invention is configured as described above, the beans such as soybeans immersed in the water supplied from the hopper 13 are used for the peeling roll 2 composed of a pair of elastic rollers 1.1.
