Pressure Granulating Spray Dryer

Introduction:

■ The set is an apparantus that can finish drying and granuliating at the same time, The needed ball granule with certain size and ratio can be got in accordance with requirements of process by adjusting pressure flow. and size of atomizing hole.

■ The working processs of the set is as follow: the liquid of raw material is pumped through high-pressure pump,the liquid of raw material atomizes to small drops, then it gathers with hot air and fall off. Most parts of powder material will be collected through the outlet of discharge at the bottom, The wasted air and fine powder will be separated through cyclone, The wastes air will be exhause through draught fan and powder will be collected at the bottom of cyclone, At the outlet it can also equipped with two grades of duster, It ratio of recove will be over 96%-98%.

■ The tower body, pipes, separator of the set where will contact with raw material made of SUS304. There is enough layer of heat preservation between inner and outer of tower body, The filled material is fine glass cotton, The tower body is also equipped with observation door, sight glass, lamp-house and control instruments that is controlled and displayed through electric control panel.

■ The heat source of the set may be steam or electric heater,Its feature are convenient in operation, quick in start,compact structure, clean of hot air and so on, Moreover being installed control and regulating device inside electric control cabinet, the inlet temperature can be controlled through stepless regulation. The steam, coal fule can be applied to the place where has not electricity. It can replace electric heating locally or fully, The factory can previde different heating method in accodance with the practical condition of customer..

Scope of application:

■ Granulating through atomizing dry:

Chemical indudtry: Organic catalyst,resin,synthetic washing powder, oils, thiamin, intermediate of dyestuff, white carbon black,graphite, ammonium phosphate and so on.

Foodstuff: Amino acid and similar subatances, flavoring, protein, starch, dairy products, extractiv. from coffee, fish powder, extractive from meat and o on.

Pharmaceutical: Chinese traditional medicines, pesticide, antibiotic, medical drinkinng and so on.

Ceramics:Magnesium oxide, kaoline, All kind of metallic oxide, dolomite and so on.

■ Granulating through atomizing:

All kinds of fertilizer, aluminium oxide, ceramics powder pharmaceut ical, heavy metal l ic super hardness steel, fertilizer, washing powder, Chinese tranditional medicines and so on.

■ Granulating though atomizing cooling:

Amino fatty acid, paraffin wax, glycerate, tallow and so on. The drier in the fields of aomizing crystal, concentrate, reaction is used often..

Feature of equipment:

■ The dry speed is fast , the surface area of raw material liquid after atomized will be increased greatly, 95%-98% of moisture can be evaporated at moment, the time of drying needs about ten seconds to several-tens seconds, it is suitable for drying material particulary .

■ The finished product is ball granule with uniform size,Its fluidity and solubility are good, the purity of product is high and its quality is good.

■ It applied scope is wide. According to the characteristics of raw material.it can use hot air to dry or use cool air to granulate, it has strong adoptability to raw materials.

■ Its opertion is simple and stable, control is simple and convenient, and easy to realize automatic operation.
