Instant Powder Spray Drying Equipment

Introduce:
 
Spray drying is the technology most widely used in the liquid technology shaping 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  paste-state liquid materials, For this reason,when the particle size and distribution of the final 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 filtered 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 fine mist liquid beads.Throug the very short time of contacting the heat air,the materials can be dried into the final products.The final products will be discharged continuously from the bottom of the drying tower and from the cyclones. The waste gas will be discharged from blower.
 

Functional features

High drying speed atomizes the material into liquid, which greatly increases the surface of the material, and evaporates 95-98% of the water in a few seconds in the hot air flow. It is especially suitable for the drying of thermal sensitive materials.

The final product has the characteristics of good homogeneity, good fluidity, good solubility, high purity and good quality.

The production process is simple, the operation is simple and easy to control. The material contains 40-60% water (special material can contain more than 90%). It can be dried into powder or granule at one time. After drying, there is no need to crush and separate. The production process is reduced and the purity of the product is improved. The particle size and water loss of the product can be adjusted by changing the operating conditions in a certain range. Content and water content, easy to control and manage.
