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.
