Abstract:
A large scale, industrial system and method for dehydrating fruits, nuts or other produce. The system includes two long air tunnels which are placed end-to-end. Each air tunnel has a conveyor which is used to transport the produce through the air tunnel. As the produce exits one air tunnel, it is dropped from one conveyor onto the other, thus permitting the produce to be turned over before it enters the second air tunnel. Each air tunnel is divided into a number of separate air chambers in which the heated, circulating air is confined so as to reduce heat loss, thus increasing the energy efficiency of the system, and also providing for separate control of the air temperature and humidity levels in each air chamber. Countercirculation of air between adjacent air chambers aids in confining the air through the separate air chambers, as well as the use of resilient flaps which are used to enclose the ends of each air chamber through which the conveyor enters and exits. A high volume rate of air flow is directed generally parallel to the direction in which the produce is transported through the air chamber, thereby enhancing the dehydration process.

The invention concerns a system to fill the cases in a uniform manner with fruit and vegetables, that is to say a mechanical device, which sees to the levelled filling of cases by means of, for instance, apples, citrus fruits, artichokes and other similar products in the course of the working of same in the fruit and vegetable factories; the system consists of an entrance conveyor (5) of the cases (2) co-ordinated with the rotating platform (1) of the filling station and with the exit conveyor (8) arranged on frames based on the floor; of a feeding conveyor (11') equipped with a belt (13) with a diaphragm angularly movable (25) in order to have the product (12) flow into the circuit (C) involving the belt itself and the near parallel one (13), when the feeding has to be interrupted: the feeding conveyor (11') is mounted on a frame (14) with an elevated level and in perpendicular direction compared with that of the entrance and exit conveyors (5, 8) in correspondence of the rotating platform (1); above the latter at the end of the feeding belt (1') and in correspondence with it the distributing machine (27) is installed in a vertically movable and guided manner, equipped with a vertical belt (30), from which project the rubber blades (29), inclined towards the top in the descending part in order to receive the product (12) from the feeding belt (13) and to transfer it to the distributing belt (41), inclined towards the front and towards the bottom, followed by a chute (45); in the plan the distributing machine (27) appears to be shifted compared with the axis (A) of rotation of the platform (11) and is equipped with an excentric rotating brush (33) in order to have the product, which would tend to form a ring-shaped rise like a bun, roll towards said axis.
Abstract:
A rotary feeder mechanism capable of attachment to and synchronized operation with a variety of different types of fruit juice extracting apparatus, in which a fruit receiving hopper is rotatable about a generally vertical or tilted axis of rotation, the received fruit being moved under centrifugal force to the hopper periphery area containing entrance openings to depending magazines in which the fruits are stored in stacked relation. The lower ends of the magazines are respectively arranged with a pair of spaced-apart gating fingers which are controlled by separate cam tracks to successively release the lowermost fruit in the magazine, while opposing release of the other fruits in the magazine, at a predetermined point of the hopper rotation. The cam tracks are adjustable to advance and retard the fruit release point, and provision is also made for the selective interchange of gating fingers having greater and lesser spacing in order to accommodate the average size of fruits to be handled in a particular locality. The cam tracks are further arranged for mounting as a unit at relatively raised and lowered positions along the axis of rotation of the hopper.
Abstract:
A fruit collector for hillside orchards, which includes a channel spaced chute formed of inflated tubes, the two sides of the chute being joined by a cross web having a series of fruit receiving openings approximately the spacing between rows of trees, the chute being laid downhill between sloping rows of trees. In a first embodiment, the openings are formed by U-shaped slits to receive fruit, and retarding flaps extend into the chute to retard movement of the fruit. In a second embodiment, the cross web is tubular, but non-inflated, and receives a series of longitudinally extensible and retractable ribbons protruding from the upper margins of the openings and extending into the chute between the openings; the strips serve to retard movement of the fruit and may be in axially overlapping relation, and adjustable to change their retarding effect thereby to compensate for different degrees of slope. In a third embodiment, which may be incorporated with the first or second embodiments, selected inflated tubes may vary between a small area and a large area to retard the fruit by creating lateral movement of the fruit. A further embodiment having a cross section similar to any of the other embodiments, is arranged in a zig-zag pattern causing the fruit to move laterally in alternate directions so as to restrict the rate of movement of the fruit, thereby permitting use on a steeper slope.
Abstract:
The machine calibrates round, oblong or spherical objects and in particular fruit and vegetables. It comprises a series of spaced-apart rollers which define cavities for receiving the objects. In these cavities, the objects rotate and place their equatorial plane in a vertical position. Calibrating rollers, oriented in a longitudinal direction or slightly inclined relative to the axis of the conveyor and at heights from the latter which decrease in the direction of conveyance of the conveyor, discharge the objects and cause them to drop through a minimum height onto a discharging conveyor placed thereunder.
Abstract:
Husked ears of corn are fed individually between the flights of a forwardly moving flight conveyor and are supported by a rearwardly moving conveyor belt which spins the ears about their axes causing them to move in the direction of their axes until the smaller ends of the ears have moved close to or engage one of the side walls of the conveyor, depending upon which direction the ears are pointing. This forms two lanes of preoriented ears. At the delivery end of the preorienting conveyor, the ears are dropped with their axes generally parallel and horizontal and the ears of each lane fall against one side of a V shaped butt deflector which defects the following butts of the ears from each lane from vertical free fall but allows the smaller ends to continue to fall freely until they encounter the deflector. The ears now slide down a chute with their smaller ends forward and the side walls of the chute converge so as to singulate the ears from both lanes into a row of ears pointed small end first which row is picked up by a rearwardly moving cutter feeder conveyor.The conveyor conducts the row of ears, which are now axially aligned pointed small end first, into a rotary corn cutter of a type well known in the art. In order to stabilize the ears and maintain their axes generally parallel until they fall against the butt deflector, light frictional engagement is made with the ears of each row, by a curtain of flexible chains hanging down at the delivery end of the preorienting conveyor.
Abstract:
An apparatus for gently transferring delicate produce from a supply conveyor into a dry storage bin. The discharge head of the apparatus has a reversible delivery board which directs and uniformly stacks the produce within the bin without bruising the produce. The transfer apparatus utilizes a series of opposed brushes on a parallel conveyor arrangement to gently support and transfer the produce to the bin. The discharge head and the bin move relative to each other in both the horizontal and vertical planes to provide uniform layers of produce and to adjust for the increasing layers in the bin.
Abstract:
In a system for classifying objects, particularly fruits, which pass successively through an inspection station for evaluation according to respective grades and for generating evaluation signals corresponding to such grades. The inspected fruits are then delivered to a distribution apparatus by means of a sorting conveyor having a single row of traveling holders for the individual fruits. The sorting conveyor has a plurality of discharge stations corresponding to the different evaluation grades and, when a holder carrying a fruit reaches a discharge station that corresponds to the evaluation grade for that particular fruit, the generated evaluation signal for that particular fruit causes the holder to discharge the fruit.
Abstract:
The present apparatus relates to cleaning means for a roller conveyor employed in a fruit and vegetable peeling operation, for example, in the peeling of white potatoes employing a lye treatment followed by the application of infrared radiant heat. The rollers which carry and turn the potatoes under the infrared rays become coated with a paste-like substance as the infrared rays take effect in conditioning the activating lye and conditioning the skin for removal, and these rolls are subjected to a cleaning operation by blade means.
