Centrifugal spray dryer principle

The liquid material (filtered liquid material) is sent to the high-speed rotating centrifugal atomizing disk, and the liquid material is stretched into a film on the rotating surface by the centrifugal force of the rotating disk and continuously moves to the edge, and is atomized when leaving the edge. The atomized droplets (large surface area) are exchanged with hot air for rapid drying in 10-30 seconds.

 

Suitable materials for centrifugal spray dryer

Chemical industry: Resins, organic catalysts, oils, ammonium sulfate, dyes, synthetic detergents, white carbon black, graphite, dye intermediates, ammonium phosphate, etc.

Food industry: seasonings, amino acids and analogues dairy products, coffee extracts, protein, starch, fish meal, meat, etc.

Pharmaceutical industry: antibiotics, proprietary Chinese medicines, pesticides, pharmaceutical granules, etc.

Ceramic industry: Porcelain clay, various metal oxides, magnesium oxide, dolomite, etc.

Spray granulation: various fertilizer bodies, alumina, ceramic powder, pharmaceutical, heavy metal super-hard steel, fertilizer, granular detergent, Chinese patent medicine, etc.

Spray cooling granulation: spray cooling granulation: amino fatty acid, paraffin, glycerate, tallow, and the like.

Others: Centrifugal spray dryers are also often used in spray crystallization, spray concentration, spray reactions, and the like.
