Description

is a kind of continuous atmospheric pressure dryer. By pneumatic or electric atomizing device, the liquid material is sprayed into mist liquid beads at high speed, which is instantly dried by contacting with hot air in the drying chamber. Widely used in electronics, ceramics, magnetic materials, battery materials, food, medicine, chemical and other industries. Spray drying is more widely used in the liquid technology shaping and drying industry process. Especially suitable for the solution, emulsion, suspending liquid and paste liquid raw materials generated in the powder or granular solid products. Therefore, when the particle size distribution of the final products, their residual water content, bulk density and particle shape shall conform to the standard, the spray drying is one of the ideal process.
WORKING PRINCIPLE: After filtering and heating, air into the dryer at the top of the hot air distributor, hot air spiraling evenly into the drying chamber. Material liquid after drying chamber at the top of the high-speed centrifugal atomizer, centrifugal spray (rotating) into tiny fog droplet, contact with the hot air flow, dry in a very short time for the finished product and whereabouts. Finished products continuously by drying the bottom and the output of the cyclone separator, exhaust dust catcher by induced draft fan emptying.
FEATURES: 1. Spray dryer is used to disperse the material into mist by using high speed centrifugal atomizer, and the drying device of powder finished product is formed when it is fully exposed to hot air.
2. Equipment installation of refrigeration dehumidification device can be in the process of material drying, can make the material in the primary cyclone discharge was immediately after cooling, won't make the material after drying in the condition of remaining agglomerate harden, after cooling of the material collected in cyclone separator, tail gas by cooling tower circulation fan back.
3. The equipment installed HEPA filter, so that the air into the air purification of 100,000.
4. The inlet air temperature is controlled automatically, which ensures the color, aroma and taste of the material will not be damaged.
5. In the tower body, the pipe is equipped with quick cleaning holes and blow-down holes, so that the cleaning is convenient and conforms to the GMP operation specification.
6. Due to poor material fluidity, the equipment is in the main tower cone and cyclone cone equipped with air hammer, so that the dry powder will not adsorb on the wall.
7. The receiving system adopts two stage cyclone separation to improve the yield of materials.
8. Unique inlet screw distributor, is the company's patent, to ensure that the tower in the circumference, the air volume is absolutely uniform down, to minimize the material sticky wall.
9. The spray tower is large, it can adjust to the drying of various kinds of materials, the inlet air temperature and the temperature setting of the wind can be controlled by manual, automatic transformation, and the scope of work is wide.
