  • Patent number: 5824356
    Abstract: There is disclosed method and apparatus for cleaning roots, tubers, bulbs, and the like, for example, sugar beets, chicory, Jerusalem artichokes, dahlia, potato, and onions (hereinafter "articles"). In the apparatus, spaced horizontal rollers have helices on their cylindrical surfaces which scroll the articles laterally to the ends of the rollers where they are deposited on a slide that removes them from the cleaner, or, optionally, returns the articles to the cleaner at strategically located lower positions for stalk removal and/or leaf stripping, or for other desired cleaning. The first sets of rollers are designed to separate small chips, small stones and loose soil from the articles. The next sets of rollers are designed to remove adhering soil and/or mud, weeds, and larger stones. Strategic placement sizing, rotational speed, and direction of rotation of the helices on the rollers are instrumental in removing leaves, stalks, weeds, breaking up dirt clods and mud balls, and cleaning of the articles.

  • Patent number: 5778771
    Abstract: A vegetable topper is disclosed. In one embodiment, the topper includes a plurality of spaced rollers which are mounted on a pair of laterally spaced roller chain loops such that the rollers are able to freely spin relative to the roller chains. The rollers define a bed on which vegetables may be positioned and the flow of vegetables along the bed is generally perpendicular to the rotational axes of the rollers. A pair of laterally spaced traction members engage the lower surface of the rollers on the "upper" portion of the roller chain loops which define the bed such that the rollers of the bed are spun by relative movement between the roller chain loops and these belts. At least two cutter blades are disposed below the bed and cut vegetable tops which extend below a pair of adjacent rollers to provide a self-cleaning feature. A paddle wheel is disposed between these two cutter blades.

  • Patent number: 5750171
    Abstract: A finish topper for bulb crops having a plurality of longitudinal, parallel, generally horizontal, spaced-apart moving belts for conveying bulbs through the apparatus. Adjacent belts are driven at different linear speeds. In a preferred embodiment, alternate belts are replaced by stationary rails to maximize the speed differential. Below and adjustably close to the belts is a driven rotating blade for cutting the bulb stems and also exerting a downwards draft of air through the belts. Onions introduced onto the belts are conveyed through the apparatus by the belts, and the differential in speed between the moving belts and stationary rails causes the bulbs to rotate and gyrate randomly as they are being conveyed. Because the belts are spaced apart, the bulbs assume momentarily an attitude to permit the uncut stems of bulbs to extend downwardly between the belts. The bulbs are retained on their shoulders on the belts in inverted posture.

  • Patent number: 5203259
    Abstract: A fruit destemmer leaving an endless conveyor belt made up of a plurality of counter-rotating metal rollers rotatably supported at each end by endless chains. The fruit destemmer has an inclined bed with a driven shaft at each end. Each driven shaft has a wheel at one end and a sprocket at the other with the positioning of the wheel and sprocket being reversed on the other drive shaft. The continuous chains are driven by spaced sprockets mounted on a shaft positioned below the inclined bed. A rotatably mounted shaft, having a wheel mounted on each end, presses each continuous chain into close contact with the driving sprockets. Any foreign matter which enters between an endless chain and a sprocket causes the endless chain to slip on the associated wheel thereby maintaining chain alignment. The rollers used to form the endless fruit conveying belt are made of hard anodized aluminum which has a surface pattern to reduce fruit skinning.

  • Patent number: 4784057
    Abstract: A cluster seprator for engaging and separating clusters of pod vegetables joined together by stem sections from a large quantity of individual pod vegetables, includes two tandem substantially horizontally spaced drums which each have a cylindrical surface such that the two drums form a restricted zone between the cylindrical surfaces. The drums are rottable in opposite directions so that the cylindrical surfaces move in the same direction at the restricted zone. On each drum are hooked rods which extend generally radially outwardly from the cylindrical surface so that a hook portion of each rod faces generally upwardly within the restricted zone. The hooked rods on each drum form an array of rods of selected density. The hooked rods pass juxtaposedly through the restricted zone at the combined densities of the arrays of both drums to optimize engagement of the clusters of pod vegetables falling through the restricted zone while permitting individual pod vegetables to fall freely between the rods.

A plurality of axially spaced stiffener partitions are disposed in an inclined cylindrical drum constructed of connected cylindrical segments in a conventional manner. Each partition has a central passage through which pod vegetables pass which is defined by a plurality of substantially straight primary edges. Notches are defined between each adjacent pair of primary edges by the extended end of one primary edge and a retaining edge extending therefrom in trailing relation to the point of termination of the leading end of the adjacent primary edge. The adjacent primary edges are spaced sufficiently to permit the stem sections of the vegetable clusters to be received within the notches for engagement by the retaining edges when the drum and baffles are rotated to remove the clusters from the mass.
