Spray drying is a wide applied process in liquid process shaping and drying industry.
Description:
The spray drier is widely used in the liquid shaping technology and in the drying industry. Particularly it is suitable for producing powder, granule or block solid product from solution, emulsion, suspending liquid and pumped paste liquid.
Features:
1. Quick drying speed. In the hot air stream, 95% to 98% of moisture can be evaporated immediately.
2. It is especially suitable for drying thermal sensitive material.
3. The product made by the machine has good uniformity, fluidity and high quality.
3. The productive process is simple and the operation control is very convenient.
4. For liquid containing 40-60% of damp (for special material, may be 90%), 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.
Application:
1. Chemical Industry:
white carbon,amino acid,catalyst,dyestuff intermediate,sodium fluoride,compund fertilizer,etc.
2. Plastics and resin:
AB,ABS emulsion, uric acid resin,phenolic aldehyde resin,urea-formaldehyde resin,polythene,etc.
3. Food Industry:
oats,chicken juice,coffee,instant dissoluble tea,protein,soybean,peanut protein,hydrolysate,etc.
4. Sugar:
corn syrup,corn starch,glucose,pectin,malt sugar,sorbic acid potassium,etc.
5. Ceramic:
aluminium oxide,ceramic tile material,magnesium oxide,talcum,etc.
