Abstract: A pressing arrangement for treatment of articles by hot pressing includes a pressure vessel including a furnace chamber and a furnace to hold the articles. A fan circulates a pressure medium within the furnace chamber, and enhances an inner convection loop at a load compartment. The inner convection loop pressure medium has an upward flow through the load compartment, and a downward flow along a peripheral portion of the furnace chamber. A flow generator generates a flow of pressure medium into the load compartment downstream the fan to enhance the inner convection loop. The flow is generated by transporting the pressure medium upwards from a space below a bottom insulating portion and above a bottom end portion, and by injecting the pressure medium into the load compartment downstream the fan to enhance the inner convection loop.
Abstract: Provided are a novel vacuum-pressure spray-drying method and a novel vacuum-pressure spray-drying apparatus suitable for drying and powdering a liquid raw material containing a substance susceptible to heat denaturation, such as a food raw material and a medicine raw material.
Abstract: The device for evaporating a treatment liquid comprises a cylindrical enclosure having an outlet orifice opening out into the top end of the enclosure, the enclosure being placed vertically and having a heated inside wall, and liquid nozzles associated with a blow pipe for blowing air under pressure so as to form a jet comprising a mixture of air and of pulverized treatment liquid in a direction that is tangential to the inside wall of the enclosure, each liquid nozzle and the associated blow pipe being arranged so that the jet of mixture is formed in an upper portion of the enclosure and is downwardly inclined.
Abstract: A device for treating a liquid comprising a solvent and a solute, and separating the solvent and solute, the device comprising a continuous flow treatment chamber including: (a) one or more drying zones; (b) one or more return zones to circulate heating fluid continuously through drying zone(s) and return zone(s) sequentially; (c) a heating fluid inlet(s) in at least one of the return zones for the introduction of the heating fluid; (d) a circulating fan to circulate the heating fluid; (e) a liquid inlet(s) in the drying zone(s) including nozzles though which liquid to be treated is introduced in misted form into the zones; (f) a solute collector(s) located in the drying zone(s) downstream of the liquid inlet(s); wherein the introduced liquid is heated by the heating fluid and the solute is separated from the liquid in the solute collector(s).

Abstract: A relatively simple portable evaporator for quickly evaporating large volumes of water includes a stand with adjustable legs, a frame carrying a tubular housing and a motor rotatably mounted on the stand for rotation around a vertical axis, a fan in the housing driven by the motor, a nozzle rotatably mounted on one end of the housing for directing air from the fan upwardly and outwardly from the housing, and a manifold carrying a plurality of jets for receiving water from a tailings pond or other source and spraying the water into a stream of air exiting the nozzle for expediting evaporation.
