LPG Centrifugal Spray Dryer
General Descriptions
LPG series high speed centrifuge atomizing dryer is a special equipment and is suitable for drying emulsion suspending liquid, liquor and so on. Particularly it has unique advantage for drying polymers and resins; dyestuff and pigment; ceramics, glass; derust agent; pesticide; carbohydrate, diary products; detergent and surfactant; fertilizer, organic compound, inorganic compound and so on.
Features
The dry speed is very quick. When raw material is atomized, the surface area increases greatly. 65~98% of moisture can be vaporized in hot air stream momentary. The dry time to be used is only 5~15 seconds. Especially, it is suitable for drying thermal sensitive raw materials.
The size of finished product is uniform and the flow and solubility are good. The purity and quality of product are good too.
The operation is stable and simple. The regulation and control is very convenient. It is easy to realize automatic operation.
The operation process is simplified and the operation environment is superior and can avoid powder dust during the period of operation.
Working Principle
After being 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 uniformly . Passing through the high-speed centrifugal atomizer on the top of the tower,the material liquid will rotate and be sprayed into the extremely misty liquid beads.Throug the very short time of contacting with the hot air, the material can be dried into the dry products. The dried products will be discharged continuously from the bottom of the drying tower and from the cyclones. The waste gas will be discharged from blower .
