Product introduction
Pressure Spray Dryer combines drying and granulating two functions together. According to requirements of producing techniques, pressure flow, spray hole size and pump of liquid material's nozzle can be adjusted, granule balls with specific size and ratio are produced.
Working Principle
Liquid raw material is input through high-pressure pump, atomized to slim water drops and sprayed, then it integrates with hot air and fall down. Majority of powder granule are collected from outlet of discharge at the bottom of equipment. The wasted air and fine powder are separated through cyclone, wasted air is exhaust from draught fan, and fine powder is collected at the bottom of cyclone. At the outlet, there is an equipped diode duster; therefore, finished powder granule collection ratio keeps at high level between 96% to 98%.
Characteristics
*Drying speed is high. When liquid raw material is atomized, the surface of the material will be enlarged greatly. In the hot air flow, 95% - 98% of water can be evaporated instantly. The time of completing the drying just only several seconds. This is especially suit for drying heating sensitive material.
*Finished products are granuled ball with uniform size; ¬humidity and solubility are good, high quality and high purity.
*Wide range of applications, strong adoptability to raw materials, depend on the characteristics of raw material, It can apply hot air or cooling air to dry and granulate.
*Simple and stable operation, brief and convenient control, easy to achieve automatic operation.
Material to be dried
*Chemical industry: organic catalyst, resin, synthetic washing power , oils, thiamin, intermediate of dyestuff, white carbon, black graphite, ammonium phosphate.
*Foodstuff: amino acid and similar substances, flavoring, protein, starch, dairy products, extractive from coffee, fish powder ,extractive from meat etc.
*Pharmaceutical: Chinese traditional medicines, pesticide, antibiotic, medical drinking.
*Ceramics: Magnesium oxide, kaolin, all kind of metallic oxide, dolomite.
*Spray Granule: All kind of fertilizer, aluminum oxide, ceramics powder, pharmaceutical, heavy metallic super hardness steel, fertilizer, washing powder, Chinese traditional medicines.
*Spray cooling granulation: Amino fatty acid, paraffin, glycerate, tallows; in the fields of atomizing crystal, spray concentrating, and spray reaction are also applied often.
