  • Patent number: 4352249
    Abstract: A fruit dryer comprising a roller conveyor passing through an elongate drying chamber is disclosed. An air plenum having a plurality of transverse nozzle openings is disposed above the conveyor and directs a series of curtain-like air streams on the fruit below. The major portion of the air within the dryer is recycled by a fan while a smaller portion of said air is exhausted by a second fan. A heater heats both the recycled air and fresh air introduced as make-up for the exhausted air. A means is provided to rotate the individual rollers of the roller conveyor as the conveyor is advanced in order to expose all sides of the fruit to the air streams.

  • Patent number: 4254877
    Abstract: A sorting apparatus classifies and discharges articles, such as items of agricultural produce, in accordance with their individual weights. A multichannel conveyor cooperates with a front end singulator which receives the produce from a source of supply and which provides the items in single file to a continuous line of spaced carrying cups moved by the conveyor along each channel. The cups are disposed for movement between an upright article carrying position and a depending discharge position, and they are supported by a rail in each channel. The rail has openings therein at each of a plurality of discharge stations spaced therealong. The cups each pass over a weighing scale aligned with the supporting rail near the front end of each conveyor channel which scale comprises a pivotally mounted bar upon which the cups ride.
