Abstract: A method and apparatus for drying grain which includes a method and apparatus for unloading the grain from a grain dryer of a type including spaced apart first and second walls for defining a passageway or grain column for directing grain flowing downwardly by gravity between the first and second walls. A substantially horizontal shelf is disposed below the outlet port of the grain confinement walls for receiving grain thereon from the grain column. A channel is disposed below the shelf for receiving grain which is pushed off of the shelf. A discharge port is disposed in the channel. A strip of material is disposed for moving along above the shelf for metering grain from the shelf to the channel as the strip moves along the shelf. A paddle is disposed for movement in the channel for pushing grain from the channel into the discharge port. The dryer also has a central air passage from top to bottom, which lends itself to being used for three mode drying, if desired.

Top belts at each of the cleaning tanks above the bottom belt to secure the produce as it passes through the first cleaning tank and through the second cleaning tank. The lower belt, and the upper belts are controlled by a single speed control system resulting in less damage to the produce. Additionally, the angle of the belts conveying the produce through the two cleaning tanks is chosen for optimum performance.

Abstract: A process and apparatus for recovering and treating hazardous and non-hazardous components from process streams generated from a continuous system for selectively separating organic and inorganic constituents from contaminated material. The contaminated material is heated in a dryer to a first temperature sufficient to volatilize water and lower boiling point constituents contained in the material, thereby producing a dried solid material and a first gas containing water vapor and volatilized lower boiling point constituents. The first gas is separated from the dried solid material. The lower boiling point constituents are recovered from the first gas. The dried solid material is heated in a desorber to a second temperature sufficient to volatilize higher boiling point constituents contained in the dried material, thereby producing a substantially decontaminated solid material and a second gas containing volatilized higher boiling point constituents.

Abstract: Method for one of drying and cooling a web in which a web is passed over an arcuate circumference of a blow device, a gas is directed from an interior of the blow device at the web through first openings formed in a mantle of the device to form a support zone between the mantle and the web, and moistened exhaust gas is drawn from the support zone into the interior of the blow device through second openings formed in the mantle. A revolving edge support is arranged at each end of the blow device to support the web during the passage of the web over the circumference of the blow device, the edge supports being separate from the blow device, and the edge supports include one of interior circumferential and friction surfaces to seal the support zone.

Abstract: Equipment provides more rapid drying of heating parts comprising hygroscopic, electric insulation made of cellulose and/or plastics. At least two condensers are present, one being used when heating the parts and the other in the distillation stage. As a result removal by distillation is possible any time during heating and during the time intervals when heating is interrupted and the pressure-dropping procedure is carried out in the vacuum vessel. Due to the second condenser (with a second, associated vacuum pump), the heating medium can be cleansed or distilled during the pressure-dropping procedure and simultaneously the suction or drying procedure can be carried out in the vacuum vessel. This feature leads to drying the electrical parts more rapidly than heretofore because the steps of drying the electrical parts and regenerating the heating medium no longer require being consecutive, but instead regeneration can be implemented simultaneously with the evacuation of the vicinity around the electrical parts.

Abstract: A device cures an adhesive by means of UV radiation in an inert-gas atmosphere. The adhesive is interposed as an adhesive layer between two superposed layers of a disc-shaped information carrier. The device includes a UV source, a supplier for an inert gas, and a holder for holding the information carrier in a centered position with respect to a centering axis. The inert-gas supplier has discharge openings for inert gas, situated in a circular zone around the centering axis, at a distance from the centering axis which substantially corresponds to the radius of the peripheral edge of the information carrier, so as to cause inert gas to flow past the peripheral edge during curing, as a result of which locally present oxygen which would interfere with curing is expelled.

Abstract: The present invention relates to a method and apparatus for use in continuously loading material to be treated into a rotary vacuum retort and continuously unloading one or more vapors or similar volatile substances and treated material out of the rotary vacuum retort during high temperature and high vacuum processing. The loading and unloading are performed in a manner that minimizes the introduction of low boiling point gases. The apparatus employs, in one preferred embodiment, elastomeric pinch valve airlocks to isolate the entire system between the airlocks and a vacuum generator. Furthermore, the material being treated may be dried in a dryer prior to introduction into the retort. Moreover, the processed material can be cooled through a heat exchanger to permit the use of a low temperature pinch valve airlock on the discharge end of the process.
