Product Introduction

Coffee drying equipment mainly includes spray dryer. Spray dryer is widely used equipment in drying industry and liquid composite molding. Particularly, it is suitable for producing powder, granule or block solid products from solution, emulsion, suspending liquid pump past liquid. Therefore, when the require granule size, left moisture content, stacking density and granule shape must be controlled precisely, spray drying is a very ideal technology.
Working principle: 
After being filtered and heated, the fresh air enters into air distributor which is on the top of the dryer. The hot air in spiral enters into the drying room. When liquid raw materials passed through the high speed centrifugal sprayer on the top of the tower, it will rotate and sprayed into the extreme slim mist liquid beads. Raw materials can be dried to required products instantly while they contact with hot air. Finished products are discharged continuously from the bottom of the drying tower and cyclones segregator. Wasted air is discharged from blower.
Application: 
Food industry: Milk powder, skimmed milk powder, cocoa milk powder, milk substitute, egg white (yolk), etc. armpit prion, Oats, chicken juice, instant tea, seasoning meat, protein, soybean, peanut protein, protein thydrolyzate, corn syrup, corn starch, glucose, pectin, maltose, potassium sorbate, pumpkin powder, instant coffee, and non-dairy creamer and etc.
Pharmaceutical products: Chinese traditional medicine extract (herb extract), medicine colloid, yeast, vitamins, antibiotics, amylase, lipase, etc.
Plastics resin: AB, ABS emulsion, urea-formaldehyde resin, phenolic resin, dense plastic (urea) formaldehyde resin, polyethylene, polyvinyl chloride and etc.


Advantages

Ø Drying speed is rapid. When liquid materials are atomized, the surface of the materials will be enlarged greatly. 95% to 98% moisture content can be evaporated instantly. It takes only several seconds to complete the whole drying process. This machine can be particularly applied to drying sensitve materials.
Ø Finished products hold many advantages such as high quality, good uniformity, good flow capability and good solubility.
Ø Simple and stable automatic operation; convenient to control and debug;
Ø Simple process; it can be applied to liquid materials whose moisture contents are 40% to 90%.
Ø Can process raw materials to powder once. Procedure of smash and sieve is simple. Superior, clean and healthy process environment
Ø No pollution to envrionment beacause of any flying powder.
