Spray Dryer
Big Spray Dryer


        This spray dryer has an evaporation capacity of 150kg/h, it is a complete spray drying unit with all the necessary accessories and controls, which is for industrial production.


  The spray drying process in liquid process shaping and drying industry the most widely used, the most suitable for the solution, emulsion, suspending liquid and pumpable paste liquid producing powder, granule or block solid products. Therefore, when the product particle size distribution, residual moisture content, density and shape of the particles must meet the precision standard, the spray drying is an ideal process.

Work principle
  Air through the heater into the hot air enters the air distributor equipment in the room at the top of the stem and evenly into the drying chamber, and spiral rotation, centrifugal atomizer and the liquid will be sent to the device in a drying room at the top, the liquid will be sprayed into tiny droplets, the liquid and the heat air flow contact. Rapid evaporation of water, in a very short time and drying. Finished product output continuously from the bottom of the drying tower and the cyclone separator, gas will be discharged by the air blower.


  Quick drying speed, liquid surface area increased significantly after the spraying, in the hot air, the moisture content of the material can be 40%-90% in the flash evaporation of water can be 95%98%, complete the drying time is only a few seconds, especially suitable for drying heat sensitive materials.
        The production process is simplified, convenient operation and control. The moisture content 40%60% (special materials up to 90%) of the liquid to a dry powder grain products, dried and crushed without screening, reduce the production processes, improve product purity. The product particle size, bulk density and moisture within a certain range can be adjusted by changing the operating conditions, control.

Technical parameters

Note: the
moisture amount to be evaporated is greatly concerned with the characteristics of raw materials, the solid content as well as the inlet/out temperature of the hot air. The user can choose the heating mode according to the local energy situations and also select the way of dust collection and dust removing as per the characteristics of raw materials.
