  • Patent number: 9027759
    Abstract: A sorting apparatus is described, and which includes a conveyor which transports a produce stream for inspection. A product separation surface is mounted near the distal end of the conveyor, and the produce stream passes over the product separation surface, and is slowed to a speed such that the produce stream falls substantially immediately vertically downwardly. An inspection zone is located downstream relative to the product separation surface. An imaging device is provided, and which images the produce stream passing through the inspection zone; an illumination device is provided for illuminating the produce stream passing through the inspection zone, and an ejector assembly is located downstream of the inspection zone and which removes unwanted solid material in the produce stream having undesirable characteristics.

  • Patent number: 8406919
    Abstract: A quality regulating apparatus and method is disclosed which operates on a product stream having an incoming product stream quality level so that an outgoing product stream quality level provided by the apparatus follows a target quality level so that it is better than the target quality level providing a maximum yield. The apparatus includes a conveying device, a product stream imager, an inspection engine, a routing engine, and an object diverting station. In operation, the inspection engine and routing engine cooperate in a manner so that objects classified as defective are intentionally passed to the output product stream when their inclusion maintains the quality level of the first output product stream at a level that is better than or equal to the target quality level.

  • Patent number: 7874081
    Abstract: A method of filling a drying system 24 with product comprises providing a washing unit 22, and a drier or driers 26a, 26b arranged such that one at a time the driers 26a, 26b receive product 48 discharged from the output of the washing unit 22. The washing unit 22 is configured to receive product 48 which is continuously weighed 104 as it is delivered to the washing unit. The product is washed in the washing unit 22 by being passed through the washing unit at a substantially constant speed, allowing the arrival time at the drier 26a, 26b to be predicted. The weight of product loaded into the drier is regulated by controlling the flow of product into the drier.
