Abstract: A hulling apparatus having a main frame, a moveable support frame, a rotatable drum fixed in position relative to the main frame, a housing supported by the moveable support frame and a hulling chamber formed by the placement of the drum inside the housing. A contact element having one or more brush assemblies is attached to the drum such that the bristles project into the hulling chamber to engage walnuts, pecans or other food products and remove the outer hull therefrom. The walls of the housing are formed from one or more screened panels having openings therein to pass the removed hull material and spiral members thereon to help guide the food products through the apparatus. The housing moves up and down to increase or decrease the size of the hulling chamber. The apparatus speeds the process of hulling walnuts and pecans and more effectively utilizes the brush assemblies.

Abstract: A beansprouts roots, husks, cleaning machine is disclosed. The machine has an internal spiral (7) and external spiral (6) in opposite directions mounted on the perforated cylinder (3) with integrated grouts bearings (8) driven by a motor rotating inside a casing cylinder (1). When the unclean sprouts are loaded by the given direction into the rotating perforated cylinder (3); causing by the rotating cycle, the roots are broken and the husks separated which then gets through the holes (4) into the gap (5) between the rotating cylinder (3) and casing (1), pushing out in one direction by the external spiral (6) as by-product. The clean sprouts are being pushed out by the internal spiral (7) in another direction as products. The machine can be used as a single or double, even multicylinders to clean the roots and husks and in different quantities of product in demand.

Abstract: The apparatus comprises a cage (rotatable in one direction) formed by roller brushes (rotatable in the opposite direction) radially arranged about a axis to define a sloped chamber. A fender is located along one side of each roller brush. A stationary tube, closed at both ends and having a motor-driven rotatable auger therein, extends through the chamber. The tube has four openings (proceeding from the high to the low end of the chamber): a top (supply) opening; a bottom (feed) opening; a top (recovery) opening; and a bottom (discharge) opening. Unhulled nuts from the supply opening are fed through the feed opening by the auger and form a single layer against the chamber wall and advance through the sloped chamber. During cage and roller rotation, each nut is trapped between a fender and the bristles in the outgoing quadrant of the adjacent roller brush and the hull is removed.

Abstract: A peeling apparatus for fruit and vegetable articles, the skin of which has been treated to facilitate peeling. The apparatus comprises adjacent elongate rolls which are spaced from one another by a distance less than the diameter of the article to be peeled. One of the rolls has, extending therefrom, a plurality of studs of substantial length and the other has, extending therefrom, studs of relatively short length. The rolls are rotated as articles to be peeled are supported on and moved longitudinally of the rolls and, thus, the treated skin is abraded off by the studs. Because the studs are of different lengths, different amounts of force are applied to the skin and the relatively long studs reach otherwise inaccessible portions of the skin.
