Fluidized bed dryer - Short flash drying of powder bulk solids - FL-T

Product catalog summary

Overview: The document provides a detailed description of Allgaier dispersion dryers, which are designed for the rapid drying of powdery bulk materials. These dryers are suitable for materials that can be pneumatically conveyed when dry and are particularly effective for products with high moisture content.

Specifications: The dispersion dryer features a cylindrical housing divided by a perforated distribution plate. Drying air enters below this plate and moves spirally upwards. The moist product is introduced from above onto a rotating disc, dispersing it into the drying air. This design ensures efficient drying with a high evaporation rate and a compact footprint.

Design Variants: The dryers offer various design options, including heat recovery, cyclone or filter separators, pressure-resistant designs, and different heating methods (steam, gas, oil, electricity, or waste heat). They can be customized for specific needs, such as inert gas circuits, solvent recovery, and explosion suppression systems.

Applications: The dryers are applicable across multiple industries, including foodstuffs (e.g., starches, flours), chemicals (e.g., pigments, plastic powders), pharmaceuticals (e.g., active ingredients, additives), environmental engineering (e.g., filter cakes), and agriculture (e.g., gypsum, limestone powder).

Advantages: The dispersion dryers offer energy-optimized processes, ensuring uniform drying results. They are capable of handling adhesive products with special coatings and provide gentle, fast drying for various product types.

Testing and Custom Solutions: Allgaier offers testing facilities to evaluate dryer performance with specific products and assists in product development and sample production. Customized solutions are available for both single units and complete plant systems.

Efficient drying technology for powders, filter cakes and fibres Energy-optimized process technology Allgaier dispersion dryers are suitable for the treatment of all materials that can be pneumatically conveyed when dry. The dispersion dryer consists of an upright cylindrical housing that is divided into two parts by a perforated distribution plate. The dispersion principle differs from the fluidized bed principle in particular due to the velocity at which the drying or cooling air is passed through the product. The drying air enters the dryer via an inlet air intake below the distribution plate...
