Abstract: The invention relates to a fluidised bed system (1) comprising a plurality of granulation units (2), arranged so as to be functionally parallel, for producing pharmaceutical granules, each granulation unit (2) comprising: a fluidised bed container (3), an inlet (4) and an outlet (5) on said fluidised bed container (3), a fluid supply (6) and a fluid discharge (7) on said fluidised bed container (3), and at least one injection nozzle (8) for injecting a processing substance into the fluidised bed container (3), as well as a control unit for adjusting processing conditions within each granulation unit (2).

Abstract: The invention reveals a process and an apparatus for treating flue gas from sintering plants, in which dry additive consisting at least of adsorbent and recirculated material is added by the entrained-flow process to the flue gas from a sintering plant in a flue gas duct, and the additive is then separated out of the flue gas by fabric filters and at least partially recirculated. In this context, it is provided that additive is introduced at least one location in the opposite direction to the direction of flow of the flue gas.

Abstract: Free-flowing solid particles are dried in a moving bed dryer by passing the particles adjacent to a heat exchanger plate containing a heated fluid while passing a dehumidified gas into the solid particles from a gas flow manifold in the heat exchanger plate.

Abstract: A method for treating a descending process flow and a spherical-shaped semiconductor integrated circuit manufacturing system incorporating the same. The manufacturing system includes a first processing station, a second processing station and first and second intermediate stations positioned between the first and second processing stations. The first processing station produces, at an output thereof, a first process flow comprised of a first process fluid and spherical-shaped semiconductors. The output of the first processing station is coupled to a first downwardly descending tube which forms an input tube of the first intermediate station. The first process flow enters a porous tube positioned inside an evacuation chamber.

Abstract: A spray dryer apparatus and method suitable for the production of detergents, cleaners and components thereof wherein the inner wall of the drying chamber is provided with an air-permeable textile material lining at a distance from the inner wall, and at least one outlet for compressed gas is provided between the inner wall and the textile material lining whereby adherence of sticky deposits on the inner wall of the drying chamber is avoided or reduced.

Abstract: The present invention is an apparatus and process for cooling and de-steaming hot calcined stucco used in the production of gypsum boards or bagged plaster. The apparatus is a fluid bed stucco cooler and comprises a cooler housing having a plenum with two chambers, a first chamber having a stucco inlet and a second chamber having a stucco outlet. The stucco cooler includes cooling coils that are located within the plenum and a fluidization pad positioned through the fluidization pad help to mix the air and the stucco powder to insure fluidization, prevent channeling, and prevent the stucco powder from building up on the cooling coils. The air also forces steam from the hot calcined stucco out through an air outlet located at the top of the stucco cooler, thereby de-steaming the stucco. The stucco flows through the plenum and passes over the cooling coils, thereby cooling the stucco as it reaches the stucco outlet.

Abstract: In fluidized spray drying of a feedstock to produce an agglomerate product by means of at least one spraying device (7) arranged in the upper part (2) of a vertically disposed drying chamber (1), in a lower part of which a fluid-bed is accommodated, a drying gas introduced into a processing zone (16) of the chamber (1) is exhausted through an integrated arrangement of filter elements (11) in the upper chamber part (2) to retain and allow agglomeration of the particles carried by the flow of drying gas on the filter elements (11).By intermittent supply of reverse flow gas pulses to the filter elements (11) the retained particles are released and returned to agglomeration zones (16, 17).The drying gas is introduced at a rate producing at the filter walls (13) a flow rate amounting to at least 150 cubic meters per hour per square meter of filter wall surface.

Abstract: The spray dryer comprises a rectangular upper body(1), a middle body(2) having a pair of side walls inclining inward and approaching mutually along larger side walls of the upper body, a rectangular bottom body(3), a ceiling board(4), a bottom plate(5), a vertical partition wall(6) for separating the upper body into a larger chamber(7) and a smaller chamber(8), and a gas stream dispersing perforated plate(14) disposed in a middle portion of the bottom body. The larger chamber(7) works as a spray drying zone and the upper half portion(17) of the bottom body works as a fluidized drying zone. Raw material fluid and hot gas are introduced downward into the larger chamber, and sprayed smaller size fluid particles are dried completely in the spray drying zone to have a low density, and enter to the lower bottom part of the smaller chamber with exhausted hot gas and turn upward to be discharged from outlet(13) disposed in an upper portion of the smaller chamber.

Abstract: In a spray drying and agglomerating process carried out in a spray drying chamber (1) having a conical lower section (3), in which chamber the liquid to be spray dried is atomized into a downward central stream of drying gas and the spent drying gas is withdrawn from non-central locations (5, 11) in the upper part of the drying chamber together with entrained fine particles, m the fine particles are recycled to the drying chamber by pneumatic injection thereof from a location in the lower part of the drying chamber and in one or more directions forming an angle of 0.degree.-90.degree. to the upward center axis of the chamber. An apparatus suitable for carrying out the process has the capability of performing the separation and recycling of the fine particles as specified.
