An apparatus for drying a material is provided. The apparatus comprises a housing, a superheated steam generator, inlet and outlet ports disposed relative to the housing and an extraction unit for extracting volatile substances from the atmosphere within the housing.

An inerted plate dryer for drying solvent based coating is disclosed. The dryer uses two tiers of substantially parallel heating plates that are located not more than 10 cm apart. A moving web with solvent based coating is passed through the dryer, and runs closer to one of the heating plates. The method of using such inerted plate dryer is also disclosed.

Exhaust air from a coater drier is sent to a desorption zone of a VOC concentration rotor. Air which comes out of the desorption zone is sent to a heat exchanger and cooled, the cooled air which comes out of the heat exchanger is sent to a cooling coil which carries out VOC concentration recovery. Air which comes out of the cooling coil is sent to an absorption zone of the VOC concentration rotor. Air which comes out of the absorption zone is sent to the heat exchanger and heated. The heated air which comes out of the heat exchanger is sent to a heating coil to be used as supply air for a coater drier. A heat pump can be used for the cooling coil which carries out cooling condensation of the organic solvent and the heating coil which heats purified air as air supply for the coater drier.

The invention relates to an apparatus for the treatment of spent material said treatment including the desolventisation and toasting of said spent material (DT) to yield desolventized spent material and/or the drying and cooling of said desolventized spent material (DC) to yield meal and/or their combination (DTDC), said apparatus being made of stacked trays supporting said spend material said apparatus being equipped with means to provide at least one fluid phase going through said spent material, wherein at least a portion of the said at least one fluid phase is pulsed through said spent material.

According to a first embodiment, a dryer for removing hydrocarbons and/or moisture from metal chips is provided. The dryer includes a top portion and a base portion. The top portion comprises an elongated tubular chamber containing a scrap conveyor. The base portion comprises a burner, a heat exchanger, a high temperature VOC elimination chamber and a vent for returning reduced VOC gasses to the top portion. The top portion is configured to receive the metal chips at an inlet and transport the metal chips to an outlet while receiving heated air from the base portion.

A multi-functional slurry processing system (VARCOR) and associated methods is disclosed. The present examples provide a multi-functional slurry processing system incorporating systems and methods for separating liquid and solid components in slurries. In particular the systems and methods described herein produce clean water, dried solids, and potential concentration of desirable constituents with a boiling point lower than water. At least one example of the multi-functional slurry processing system provides a self-contained processing facility configured to efficiently convert high water-content slurries into its constituent solid and liquid fractions and subsequently generating and collecting clean water and concentrating desirable constituents with a boiling point lower than water. The multi-functional slurry processing system advantageously applies thermodynamic principles in a system which may include various combinations of a preheater, a degassing unit, a dryer, a steam filter, a compressor, a concentrating tower, and a condensation unit.

A purifying device for purifying a process fluid that flows in a dehumidifying plant for dehumidifying plastics includes a first layer configured for filtering the process fluid, and a second layer configured for reducing, by adsorption, substances that are harmful for health, in particular COV/SOV, which are present in the process fluid.

An induction heater and materials processing apparatus and method using induction heating and rotary tumbling to heat or heat and dry materials such as drilling cuttings or waste material.

An improved desolventizer toaster. The invention includes a housing. Within the housing, a first set of trays and a second set of trays are mounted. The first trays and second trays are disposed such that they are generally vertically spaced from one another and in a generally parallel disposition with respect to each other. Means for mixing vapors are provided, and they are positioned in a vapor mixing zone which is intermediate the first set of trays and second set of trays.
