  • Patent number: 10126050
    Abstract: A system for drying moist, particulate material includes a steam dryer having a container containing superheated steam. Upper and lower heat exchangers, with a channel extending through them, are located in the container. An impeller generates a flow of steam upward in the container outside the heat exchangers and downward through the channel. Guide plates around the heat exchangers guide the moist, particulate material from an inlet in the lower part of the container around the heat exchangers, subjecting the material to the flow of the steam, thereby drying the material. A steam conduit supplies a primary steam flow to the lower heat exchanger, which condenses the primary steam flow into a flow of hot water that is directed to a flow generator that generates a fluid flow from the hot water flow. A fluid conduit leads the fluid flow to the upper heat exchanger.

  • Patent number: 6829840
    Abstract: A two-deck apparatus, one deck above the other, is provided for enabling drying of approximately twice as much material with very little increase in heat used to dry the material, when compared to a single deck dryer. The fan usually provided with dryers of this type requires only a small incremental size increase over prior art. The second or upper deck, in operation, experiences a greater pressure below that deck than the pressure above the deck. Solid material flows into the top of the apparatus from above, and then from the upper deck to the lower deck through what is essentially a one-way valve, with air flow moving from below the lower deck through the upper deck, without impeding the material flow downwardly in the apparatus. The same apparatus, but with the use of cold air to cool the product, rather than hot air to heat and dry a product, is also within the teachings of the present invention.

  • Patent number: 6270584
    Abstract: Method and apparatus for cleaning and/or drying objects that may have been wetted or contaminated in a manufacturing process. The objects are submerged in a rinse liquid in an enclosed chamber, and aerosol particles from a selected liquid are introduced into the chamber above the rinse liquid surface, forming a thin film on this surface. As the rinse liquid is slowly drained, some aerosol particles settle onto the exposed surfaces of the objects, and displace and remove rinse liquid residues from the exposed surfaces by a “chemical squeegeeing” effect. Surface contaminants are also removed by this process. Chamber pressure is maintained at or near the external environment pressure as the rinse liquid is drained from the chamber. Inert gas flow is employed to provide aerosol particles of smaller size and/or with greater dispersion within the chamber. Continuous filtering and shunt filtering are employed to remove most contaminants from the selected liquid.

  • Patent number: 5537757
    Abstract: Seed cotton on a wire mesh belt is dryed and cleaned by a downflow of heated air. The natural separation and falling of trash from the belt is increased by shaking the mass of seed cotton upon the wire mesh belt. The belt is flexed to shake the seed cotton upon it. The belt is flexed by running the belt over "V" shaped intermittent supports. The belt is also shaken by being bumped by gussets on rollers beneath the belt. The air is exhausted from beneath the belt by ducts extending across the chamber. The tops of the ducts are inclined planes so that the trash slides from the top of the duct and does not accumulate on the top.

  • Patent number: 5524356
    Abstract: The present invention provides apparatus for low-cost extraction of oil residues from oil filters. The apparatus of the invention has a mounting structure or plate to which a number of oil filters can be strapped. Over 95% of the oil in each filter can be drained therefrom under the influence of gravitational forces. Oil draining from the oil filters is allowed to gather in a pan, bucket, container or well located below the mounting plate. Connected to the mounting structure is a mechanical or electrical oscillator for imparting a vibratory oscillation to the mounting structure and, hence, to the mounted oil filters. The weak surface tension and molecular forces between the residual oil molecules and the paper filter materials will be overcome by the vibration, and the residual oil will run off.

  • Patent number: 5392529
    Abstract: A bulk material processor includes a tray assembly with a panel subassembly having an upper panel section and a lower panel section. The upper panel section is adapted to receive bulk material and pass it to the lower panel section for discharge. A heater panel is mounted over the tray assembly for radiantly heating the bulk material passing thereunder. A vibrator is coupled to the tray assembly for vibrating the bulk material whereby it advances along the tray assembly. A control system is provided for controlling the operation of the vibrator and for controlling the output of the heater panel. A method of bulk material processing includes cascading the bulk material from an upper panel section to a lower panel section by vibration and subjecting it to infrared radiation.

  • Patent number: 5341580
    Abstract: A method for drying wood strands and the like is shown and described. In a preferred embodiment, the strands are fed onto a conveyor which then moves the strands as a bed through a dryer housing. The housing may be partitioned into various zones and levels, depending on the desired configuration. A volume of drying air is heated and then passed through the bed of strands to reduce the moisture content of the strands. In a preferred embodiment, the strands are agitated to promote the even exposure of the strands to the drying heat. The strands are then conveyed through a conditioning zone before being discharged from the dryer housing.

  • Patent number: 5316076
    Abstract: A method and arrangement for enforced heat transmission between a solid or liquid alimentary body and an ambient gas takes place in connection with cooling/freezing or when cooking, frying or drying the entire part or parts of the alimentary body. This method and arrangement uses a low-frequency standing sound wave. The apparatus uses a low-frequency sound generator having a pulsator part and a resonator part. The resonator part is acoustically virtually closed and is designed so that the alimentary body, which is to be exposed to enforced heat transmission, is located within a zone inside the resonator part where the standing sound wave has a particle velocity anti-node.
