NOZZLE TOWER™ spray dryer is uniquely designed to produce a chemical powder that is free flowing, dustless and consists of hard, big, single particles. As the name of this spray dryer indicates, the atomization is done by nozzles typically mounted in the air disperser at the top of the spray drying chamber.

The conventional spray dryer is referred to as a one-stage spray dryer as the powder has its final moisture content when discharged from the plant. It is available with a rotary atomizer in a co-current air flow as well as with high pressure nozzles in both co-current and counter-current air flow. It can also be delivered with one point product discharge with the exhaust air from the cyclones or bag filter collector or two point product discharge from the drying chamber base and cyclone or via apneumatic conveying/cooling system.

Pressofiltro Filter Dryer is used for the manufacture of sterile parenterals, i.e. substances which are intended for injection, infusion or implantation into the human or animal body, the issue of sterilization of process equipment is of high priority. The design of steam sterilisable Pressofiltro agitated nutsche filters and filter dryers ensures complete sterility throughout the whole process, from inerting to feeding with suspension, filtration, washing and drying to the discharge of the dry product. In compliance with cGMP and FDA guidelines, the vessel interior and all associated piping is designed to prevent product adherence and to facilitate cleanability. The aseptic design (of flanges, seals, valves, etc.) provides a complete drainage of CIP liquid and condensate during the heating process.

Fluid Bed Dryer which is used in pharma industries is provided with single piece construction without flange joints. It is a complete dryer having stainless steel construction with mirror polished product contact surfaces. The edges of all the parts of Fluid Bed Dryer are rounded off and only butt welding is carried out. It is provided with filter bag sealing arrangement by means of inflatable tube and further it has interlocking between filter bag sealing tube, blower motor and exhaust butterfly valve.

Lab Tray Dryer are used for drying of pharmaceutical powders, granules, Pigments, Chemical and Plastic etc in an effective and economical way by hot air re-circulation. Tray dryer is an enclosed insulated chamber in which trays are placed on top of each other. Heat transfer is done by circulation of hot air by electric heaters or any other heating media. Blower fans are installed inside to ensure proper circulation and transfer of heat. Further it is provided with digital temperature and timer control.

Fluid Bed Dryer involves fast drying, cooling and agglomeration of particulate materials. It is ideal for heat sensitive and non heat sensitive products in Pharmaceuticals, Chemicals and Biochemical, Food and Dairy Industries. The Fluid Bed Dryer have a bed of solid particles which are fluidized by passing a stream of air upward through a specially designed perforated sheet. The upward velocity of air is so maintained so as to slightly lift the solid particles and set them in motion. This motion can be utilized to bring about mixing as well as forward movement of the solids particles. The air is heated and the process hot air evaporates the fluid and dries the solids.

Rotary Vacuum Dryers.

Fluid Bed Dryers are ideal for air fluidization for drying granules, crystalline, coarse or similar materials in pharmaceuticals, fine chemicals, dyes, food & allied industries. The structure of fluidization bed is of round so as to avoid dead corner. Inside the hopper there is a stirring device in order to avoid agglomeration of raw material and forming canal of flow. The granule is discharged through the method of turning over. It is very convenient and full. The discharged system can be designed as request too. It is operated at conditions of negative pressure and seal. The air is filtered. Therefore it is simple in operation and convenient for cleaning. It is an ideal equipment that is in conformity with the requirements of GMP. The drying speed is fast and the temperature is uniform. The drying time is 20-30 minutes normally.

Conical Blender Dryer are designed for drying and blending, in one operation, aggressive or metal-sensitive substances, also suitable for impregnating and concentrating, for pharmaceutical products, synthetic resins and other plastics, dye-stuff and pigments, metal soaps and catalyzers. As the unit revolves, the top layers of the product roll down, constantly exposing new surface areas for faster drying. The gentle tumbling action intensifies the drying process while handling the product carefully, assuring an intimate mixture. The double cone shape balances the forces caused by the rotating product, prevent a substantial transfer of the gravity centre, protecting the aggregate from periodic impact stresses. Operation under vacuum increase the drying speed respectively enables lower temperatures, which furthermore preserve the product.

Continuator Indirect Drying System is a jacketed ribbon blender-type device best suited for additional post-thermal treatment, and batch operations for long reacting or thermal drying cycles. Batch or continuous operations ideal for pre-blending, reacting, volatile removal, and 2nd-stage material heating. It is provided with different rotor configurations, such as paddles or ribbons, available for ideal agitation and handling of material phase changes. The liquid and gas injection points can be incorporated throughout the body for even distribution of additives. Its simple design provides a lower-cost option for thermal treatment.
