Table de tri à rouleaux trieurs pour l'élimination des corps étrangers restant mêlés aux produits de la récolte de petits fruits, caractérisée en ce qu'elle comporte un système trieur constitué par une succession de rouleaux rotatifs de forme cylindrique (2) disposés parallèlement de sorte à former un plan de tri mobile, et des moyens moteurs (19, 20) permettant l'entraînement en rotation desdits rouleaux (2) dans le même sens, de sorte à permettre un déplacement de la vendange déversée sur la partie amont (3) de ce plan de tri, dans une direction perpendiculaire à l'axe desdits rouleaux rotatifs cylindriques (2) et sur toute la longueur dudit plan de tri, et en ce que lesdits rouleaux rotatifs cylindriques (2) sont agencés de sorte à permettre, le passage et la chute des petits fruits à trier seulement, les corps étrangers de taille supérieure à celle de ces derniers restant à la surface du plan de tri mobile et étant évacués à l'extrémité aval de celui-ci.

Provided is a supply device for supplying articles, especially "bean sprouts-like articles", in a loosened state and that can exhibit a sufficient dispersing function even for fine and light weight bean sprouts-like articles liable to be entangled with each other, such as alfalfa sprouts. The loosening supply device comprises at least one pair of transfer conveying devices (1,10;30,40) which respectively have a plurality of needle members (6,16;36,46) arranged to protrude from their outer surfaces and which are adapted to move at velocities different from each other. The transfer conveying devices (1,10;30,40) of the pair are arranged such that they have moving paths opposed to each other at at least one portion so that the moving directions are the same at the at least one portion and that the needle members (6,16;36,46) protruding from the transfer conveying devices (1,10;30,40) at least partly mesh with each other at the at least one portion. The articles like sprouts to be supplied by the supply device are supplied into the running paths from above and encounter the needle members of the two transfer conveying devices running at velocities different from each other and intersecting with each other. On each time of the needle members intersecting with each other, the sprouts are separated upward and downward and dispersed.

A water-saving type fruit and vegetable washing and disinfecting method and device, the washing process of which utilizes a middle water level spray wash combined with a water flow tumbling and swirling ozone wash. The wash trough bottom section has disposed a return flow water discharge port, a water discharge valve drain pipe, and numerous spray ports. Its bottom section also has disposed at the center a multi-orifice spray spindle; its lateral wall has disposed numerous spray ports. Disposed near the side wall of the bottom section is a return flow water input port. The device also consists of a return flow water pump, its water input port connected to the return flow water discharge port and its water output port connected to the return flow water input port; a return flow spray pump, its water input port connected to the return flow water discharge port and its water output port connected to numerous spray ports, lateral wall spray ports, and the multi-orifice spray spindle. When washing, the return flow water pump is started, the basket rotates in the direction of the water flow, the centered multi-orifice spray spindle and the wash trough spray ports emanate water flow and ozone bubbles to wash the fruits and vegetables, a water level controller utilized to set different water levels. The method also includes water input, drying, water drainage, and foreign matter elimination. As such, the present invention achieves water-saving washing that is an improvement over manual washing inadequacies.

A peeling apparatus (20) comprises a frame (30) and first and second peeling chambers (26a, 26b) carried by said frame (30) in side-by-side relation. The first peeling chamber (26a) comprises a first set of abrasive rollers (32a) and a first auger (33a) adjacent thereto. The second peeling chamber (26b) comprises a second set of abrasive rollers (32b) and a second auger (33b) adjacent thereto. The first and second augers (33a, 33b) comprise respective helical flights oriented in opposite helical directions and a drive for driving the first and second augers (33a, 33b) in opposite rotational directions.

Device for cutting the calyx and the stem of hortofruit culture products, comprising a device (1) mounted on a conveyor belt (2), on which the fruits are conveyed, incorporated in the sides (3) of the conveyor belt, configured by a tubular portion (4), related with another extreme coaxial portion (5), through the use of a bearing (6), the external portion (5) being associated through springs (7) with another upper portion (8), capable of effecting an axial displacement and through which is moved the tubular rotary part (4) which is provided at its perimetral extremity with a toothing (9), and an internal inclined blade (10), the toothing (9) being intended to remove the calyx of the fruit, while the blades (10) remove the stem.

The device comprises a compartment for receiving fruit (1), an area for suction of fruit (10) and an area for suction of liquid (11) which comprises a first orifice (3) and a narrowing (7) which flows into a channel (12), with a water flow (14) between the narrowing (7) and the channel (12), with the channel (12) forming part of a pipe (8) which carries the impelled liquid inside the channel (12). The method comprises the steps for supplying a mixture of fruits in bunches and liquid, moving the mixture to a fruit suction area (10) through a suction entrance (6), aspirating and injecting liquid at high speed through the channel (12) generating a depression which drags the mixture towards a narrowing (7), generating turbulence which separates the stalks from the fruit and extracts the separated fruit.
