Working Principle and Characteristics of Pressure Spray Granulation Dryer

The working principle of this machine is that the air enters the heater through the filter, exchanges into the hot air, and goes into the hot air distributor at the top of the drying room, so that the air uniformly enters the drying room in the form of rotating or parallel axis. The material to be sifted by the high-pressure pump to the nozzle located in the top centre of the drying room, the material will be uniformly atomized, so that the surface area of the liquid droplets greatly increased, and hot air meets the contact, so that water evaporates rapidly, in a very short period of time to dry into particles of the product, the majority of the product by the bottom of the tower at the discharge port to collect the waste gas and small particles of powder by the cyclone separator separation, the finished product by the cyclone collector at the lower end of the collection of cylinder collection, exhaust gas Exhaust gas is discharged by extractor fan.



This machine is the use of parallel pressure form to achieve drying and granulation, so the user Section according to their own needs the size of the product particles, to adjust the amount of liquid spray and nozzle aperture and the concentration of liquid or additives added to the appropriate process, so that it reaches their desired particle size requirements.



The characteristics of this machine is due to the nozzle will material liquid uniform atomisation, so that the material liquid to form a very fine droplets, so that a total of atomised area greatly increased, the entire drying process is completed in an instant. Therefore, the drying time is short and the original characteristics of the material can be guaranteed. Another unit of the cylinder body, the cylinder road and the contact material parts are made of 1CR18NI9TI stainless steel material, so the product is not affected by the production of materials that cause pollution, the production of unqualified products.



This machine can usually be used for solid content of 40 ~ 60% of the material for spraying, liquid can be adapted to some of the solid content of large or small special materials for spray drying, a one-time into a granular product. Most of the materials collected after spray drying finished product, no longer need to crush and screening, both simplify the production process, but also reduce the production process.
