  • Patent number: 6206175
    Abstract: A conveyor cleaning and residue control system for use with a conveyor includes an air knife and a deflector. The air knife impinges an air stream against the conveyor to blast residue from the conveyor, and the deflector redirects the air stream and the residue loosened by the air stream toward a chute. The flow of the air stream toward the chute causes at least a portion of the air-borne residue in the vicinity of the conveyor to flow toward the chute with the air stream such that the residue becomes supersaturated and forms macro-particles that precipitate out of air suspension. The air knife and deflector thus recycle the residue carried by the conveyor instead of requiring it to be evacuated. In the first embodiment, the deflector includes a pair of non-coplanar blades that are attached to one another. The deflector is both rotationally and translationally adjustable with respect to the conveyor. A second embodiment is disclosed wherein the deflector is curved.

  • Patent number: 6058556
    Abstract: A movable-head cloth-cutter bristle block cleaner for cleaning a conveyor-type bristle bed trained between the rotatable end units of a cloth cutter. The cleaner has a movable head attached to a cable cylinder which is coupled to the frame of the cloth cutter. The head moves substantially the entire width of the bristle bed. In one embodiment, nozzles are placed in several rows on the head and are positioned so that they extend into the bristles of the bristle bed. The movable head is coupled to a supply of compressed air. When the bristle bed moves, high volume, high pressure air is delivered to the head and then shoots out of the nozzles. The jetting action of the gas leaving the nozzles effects removal of debris contained within the bed. Because the cleaning head moves across the entire width of the bristle bed, fewer nozzles are needed to clean the bristle bed. This allows the air pressure coming out of the nozzles to be delivered at a high level.

  • Patent number: 5613594
    Abstract: The present invention relates to an apparatus and a method for treating a conveyor belt with a treatment fluid while minimizing the amount of over spray of the treatment fluid into the air and onto the surrounding equipment and materials. For example, a pervious conveyor belt used in the cooking or other processing of food may be washed, scrubbed, or rinsed with water or a mixture of soap and water without causing overspray of the cleaning or rinsing fluid. Also, the apparatus and method may be used to spray a high quality non-stick coating onto the pervious conveyor belt without over spray of the non-stick coating onto surrounding plant equipment and materials. Overspray is minimized by the placement of treatment fluid flow diverters at the conveyor belt entrance and exit to divert the flow of treatment fluid away from the entrance and exit.

  • Patent number: 5564555
    Abstract: A hollow shaft of a screw conveyor for transporting powder material receives pressurized air in its interior. A plurality of openings through the wall of the hollow shall permits the pressurized air to exit energetically to prevent build-up of the powder material on the inside wall of the casing of the screw conveyor. In one embodiment, the openings are slits angled with respect to the axis of the screw conveyor at about the same angle as the helical blade. This produces a swirling flow of air which, in addition to preventing build-up of materials, enhances the advance of the powder material and, when the powder material is a mixture of different materials, helps prevent separation of the materials during transport.
