LPG Series High-Speed Centrifugal Spray Dryer

Description: The spray drying is the technology widest used in the liquid technology shaping and in the drying industry. This equipment is especially suitable for producing powder or particle solid products from materials such as solution, emulsion, suspension and pasty states. For this reason, the particle size and distribution of the final products, the residual water contents, the stacking density and the particle shape must meet the precision standard. Features: 1. At a high speed of drying, the superficial of the feed liquid will be increased greatly after the spraying. In the hot-air flow, 95%-98% of wather can be evaporated at a moment. The time of completing the drying needs only several seconds. 2. This is especially suitable for drying the heat sensitive materials. Its final products are high in purity and good in quality. And they have good uniformity, mobility, dissolving capacity. The production procedures are simple, the operation and control are easy. 3. The liquid with the moisture contents 40%-60% (for special materials, the contents may reach 90%) can be dried into powder or particle products at one time. After the drying, there is no need for smashing and sorting, so it reduce the operation procedures in the production and enhance the product purity. The product particle diameters, looseness and water contents can be adjusted through changing the operation condition in a certain scope. It is very convenient to control and manage. Principle: After the filtering and heating, the air enters into the air distributor on the top of the dryer. The hot air enters into the drying room in the spiral form and uniformly. By passing through the high-speed centrifugal spray on the top of the tower, the liquid material will rotate and be sprayed into the extremely fine mist liquid beads. Through the very short time of contacting the hot air, the materials can be dried into the final products. The final products will be discharged continuously from the bottom of the drying tower and from the cyclone separator. The waste gas will be discharged from blower. Applications: 1. Chemical: sodium fluoride(potassium), alkaline dyestuff and pigment, dyestuff intermediate, compound fertilizer, formic silicic acid, catalyst, sulphuric acid agent, amino acid, white carbon and so on. 2. Plastics and resin: AB, ABS emulsion, uric acid resin, phenolic aldehyde resin, urea-formaldehyde resin, formaldehyde resin, polythene, poly-chloroprene and so on. 3.
