Product introduction
  Spray drying is the technology most widely used in the liquid technology s haping and in the drying industry.The drying technology is most suitable for producing solid powder or particle products from liquid materials,such as:solution, emulsion, suspension and pumpable paste states,For this reason,when the particle s ize and distribution of the nal products,residual water contents, mass density and the particle shape must meet the precise standard, spray drying is one of the most desired technologies.
Working Principle

  After been ltered and heated the air enters into the air distrbutor on the top of the dryer.The hot air enters into the drying room in the spiral form and uniformly . Passing through the high-speed centrifugal sprayer on the top of the tower,the material liquid will rotate and be sprayed into the extremely ne mist liquid beads.Throug the very short time of contacting the heat a ir,the materials can be dried into the nal products.The nal products will be discharged continuously from the bottom of the drying tower and from the cyclones. The waste gas will be discharged from blower .
Characteristics

◎ The drying speed is high when the material liquid is atomized,the surface area of the material will increase greatly.In the hot-air ow,95%-98% of water can be evaporated at a moment.The time of completing the drying is only several seconds. This is especially suitable for drying the heat sensitive materials.
◎The product particle diameters,looseness and water contents can be adjusted through changing the operation condition within a certain range. It is very convenient to carry out control and managment.
◎Its nal products own the good uniformity, ow ability & solubility. And the nal products are high in purity and good in quality .The producition procedures are simple and the operation and control are easy .The liquid with moisture contents of 40-60%(for special materials,the contents might be up to 90%).can be dried into the powder or particle products once a time. After the drying process, there is no need for smashing and sorting,so as to reduce the operation procedures in the production and to enhance the product purity.

Note:The evaporated amount of water its related te characteristics of raw materials and the temperature of air in and air out.When the temperature of air out is 90oC,the evaporated curve of moisture is listed in above Fig(for reference when choose the Model).With renew procucts unceasingly,the related parameters will be exchanged,it does not announce in advance,pardon!


Attention to order
◎Liquid name and property: Solid contents(or water contents), viscosity , surface tension and PH value.
◎Dry powder density residual water contents allowed, particle size, and maximun temperature allowed.
◎Output: shift time daily .
◎Energy that can be supplied: steam pressure, electricity properly , fuel of coal, oil and natural gas .
◎Control requirement: whether or not the inlet and outlet temperatures should be controlled.
◎Powder collection requirement: whether it’s necessary to use cloth bag lter and the requirement of the environment of the exhausted gas .
◎Other special requirements.
