5. Product collecting type: Two degrees cyclone separator (Collecting level>*8%)
6. Atomizing type: Centrifugal type atomizing
7. Control system: Touch screen & PLC
8. Air filter system: Pre, middle and sub-high efficient filter (**0,**0 degree)
9. Discharging system: Cool air (dehumidifying) cooling collecting

2. General description of LPG Centrifugal Dryer:

Spray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas. This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals. A consistent particle size distribution is a reason for spray drying some industrial products such as catalysts. Air is the heated drying medium; however, if the liquid is a flammable solvent such as ethanol or the product is oxygen-sensitive then nitrogen is used

All spray dryers use some type of atomizer or spray nozzle to disperse the liquid or slurry into a controlled drop size spray. The most common of these are rotary disks and single-fluid high pressure swirl nozzles. Alternatively, for some applications two-fluid or ultrasonic nozzles are used. Depending on the process needs, drop sizes from *0 to **0 µm can be achieved with the appropriate choices. The most common applications are in the **0 to **0 µm diameter range. The dry powder is often free-flowing

Spray Drying is still the most economical method of evaporation to reduce a liquid feed to solid powder particles. Powder remaining one of the most versatile methods of preservation and cost effective in both storage and transportation of finished goods.

  3. Features of LPG Centrifugal Spray Dryer:

1. Quick drying speed, the surface area of material liquid through atomizing is increased greatly. In hot air stream, *5%~*8% of moisture can be evaporated at moment. Particularly suitable to finish drying thermal sensitive material.
2. The product made by the machine has good uniformity, fluidity, solubility, high purity, and high quality.
3. The productive process is simple and the operation control is very convenient. For liquid containing is *0%~*0% (for special material, may be *0%), it can be dried to powder product through drying one time. After dried, it is not necessary to crush and sieve. So it reduces productive procedure and raises the purity of product. For the size, bulk density and moisture of product can be adjusted within certain scope through changing operation condition. The control and management are very convenient.
