Abstract: A double blade peeling device for vegetable and fruit comprises a handle attached to a vegetable and fruit retaining member and a body of screw, the handle can drive internal gears to rotate, so as to make the retaining member and the body of screw to rotate as well. The body of screw, which is provided with two screw threads, drives upper and lower blade carriers to move upward and downward oppositely, such that the blades mounted on the upper and lower blade carriers move downward and upward respectively, contact the rotating food frictionally, and peel vegetable or fruit from upside and underside simultaneously. When two blade carriers move to the intermediate position to complete the peeling action, the two blade carriers open through wedge in blade carrier devices, two blades leave the surface of food, the lower blade carrier devices disengage with the body of screw. The body of screw drives upper blade carrier device to press the lower blade carrier device to move downward unceasingly.

A first large-diameter pulley and a second small-diameter pulley are attached to a second roll shaft. This configuration makes it possible to switch between a first driving state in which a rice hulling operation is performed by passing and driving a belt between the first small-diameter pulley on the first roll shaft and the first large-diameter pulley on the second roll shaft and a second driving state in which a rice hulling operation is performed by passing and driving a belt between the second large-diameter pulley on the first roll shaft and the second small-diameter pulley on the second roll shaft.

Abstract: A husking apparatus supplies cereal grains between a pair of rotating rubber rolls through a guiding chute, rubs and husks them. A roll diameter marker for indicating an abrasion degree of the diameter of one of the rubber rolls is provided near the minimum gap between the rubber rolls. An incline angle changing marker previously marked with a changing degree of a position or an angle of incline of the guiding chute in correspondence to the roll diameter marker is provided near the lower end of the guiding chute. An operator can readily detect the diameter of the rubber roll by means of the roll diameter marker and accurately set the position or the angle of incline of the guiding chute in accordance with the incline angle changing marker.

Abstract: A husking apparatus for cereals comprises a pair of rolls provided parallel to each other with a clearance therebetween, and an inclined guide chute situated above the rolls. The guide chute slides down cereal grains between the rolls, and the rolls rotate in opposite directions, respectively, to nip and shell the cereal grains therebetween. The guide chute and the rolls are located so that a guide surface of the guide chute is substantially perpendicular to a line connecting the centers of rotational shafts, and that an extension line from the guide surface passes within a range of .+-.10 mm on both sides of a middle point of the clearance between the first and second rolls. The guide surface of the guide chute has such an inclination that the cereal grains spread all over a width of the guide surface in the substantially single layer of a band-like shape and are accelerated up to a speed less than peripheral speeds of the rolls while they slide down along the guide surface.

Abstract: Two counter rotating rollers are provided having elastomeric exterior coatings into which ribs and grooves are formed for intermeshing to blanch nuts at a pinch point therebetween. Grooves in the lower roller hold nuts as ribs on the upper roller pass across the nuts to break skins on the nuts. The elastomeric exterior coatings have surface hardness values which measure around 30 durometer. The squeeze at the pinch point between the two rollers can be repeatably adjusted for running different sizes of nuts.

Abstract: Peeling rollers for vegetables, particularly root crops each comprising an hourglass-shaped core roller having a recessed portion defined and an outer cylindrical elastomer member concentrically surrounding the core roller, thereby constituting a space enclosed by the recessed portion and the elastomer member, the elastomer member being attached with abrasive pieces, the space being a hollow.

Abstract: A roller assembly for grain shellers, the assembly including a metal sleeve having first and second apertures therein, a sleeve of flexible material bonded to the exterior of the metal sleeve with portions of the flexible material sleeve extending into the metal sleeve first apertures, the metal sleeve being adapted for connection to a mounting hub, and pin means extending from the mounting hub and into the second apertures of the metal sleeve.

Abstract: A method for making a roller sleeve assembly comprising providing a metal sleeve, forming apertures extending radially through the sleeve, bonding a flexible sleeve to the exterior of the metal sleeve and permitting the flexible sleeve material to fill certain of the apertures. The invention further contemplates a method for making a roller assembly comprising sliding the above-described sleeve assembly onto a hub comprising a circular wall with ribs extending normally therefrom, and providing locking plates and cooperative pins for locking the sleeve assembly onto the hub, with the pins disposed partly in the locking plates and partly in other of the sleeve assembly apertures.

Abstract: A device for removing coatings from granular materials such as hull-encased meats of grains. The device includes a housing within which is journaled a rotatably disposed drum. A wall is also mounted within the housing, the wall angling downwardly and being spaced at a distance from an outer surface of the drum to define a processing space therebetween. Typically, the processing space narrows downwardly within the housing. The drum is disposed for rotation so that any material fed into the housing through a hopper mounted on the top thereof will be drawn along the drum surface into the processing space. The processing space narrows sufficiently so that an abrasion is effected upon the material as it is deposited within the processing space because of the relative movement of the outer surface of the drum and the downwardly extending wall.
