Descriptions

The spray drying is the technology widest used in the liquid technology shaping and in the drying industry. The drying technology is most suitable for producing the powder, particle or block solid products from the materials, such as: solution, emulsion,soliquoid and pumpable paste states. For this reason, when the particle size and distribution of the final products, their residual water contents, the stacking density and the particle shape must meet the precision standard, the spray drying is one of the most desired technologies. 

Principle

After fresh air is filtered and heated, it enters into the air distributor which on the top of the drier. The hot air in spiral form equably enters into the drying room. When liquid raw material are  passed through the high-speed centrifugal sprayer on the top of the tower, it will be rotated and sprayed into the extreme slim mist liquid beads. Raw material can be dried to the final products instantly while it contact with the heated air. Finished products are discharged continuously from bottom of the drying tower and cyclones segregator. Wasted air is discharged from blower.

 

Applications 

â—ŽChemical Industry

Sodium fluoride(potassium), alkaline dyestuff and pigment, dyestuff intermediate, compound fertilizer, formic silicic acid,catalyst, sulphuric acid agent, amino acid, white carbon and so on.

â—ŽPlastics and resin

AB, ABS emulsion, uric acid resin, phenolic aldehyde resin, urea-formaldehyde resin, formaldehyde resin, polythene,polychloroprene and etc.

â—ŽFood Industry

Fatty milk powder, protein, cocoa milk powder, substitute milk powder, egg white(yolk), food and plant, oats, chicken juice, coffee,

instant dissoluble tea, seasoning meat, protein, soybean, peanut protein, hydrolysate and so forth. 

Features

â—ŽFast drying speed, the surface area of material liquid through atomizing is increased greatly. In hot air stream, *5%**8%of moisture can be evaporated at the moment. Particularly suitable to finish drying thermal sensitive material.

â—ŽThe product made by the machine has good uniformity, fluidity, solubility, high pure and high quality.

â—ŽThe productive is simple and the operation control is very convenient. For liquid containing *0%**0% of damp ( for special material, may be *0%), it can be dried to powder product through drying one time. After dried it is not necessary to crush and sieve. So it reduces productive procedure and raises the purity of product. For the size, bulk density and moisture of product can be adjusted within certain scrope through changing operation condition. The control and management are very convenient.
