Product Description

1. Introduction and application:
High speed centrifugal spray dryer is widely applied in liquid technique shaping and drying industry.
Suitable for producing powder, granules or blocked solid products from emulsion, suspension, solution, paste liquid and so on.
When the distribution of granule size, final moisture content, stacking density, and shape of granule of finished product must conform to accurate standard, centrifugal spray dryer is an ideal process.
Particularly for liquid spray and drying shows excellent advantages in drying polymer and resin, dyestuff and pigment, ceramic, glass, pesticide and fertilizer, carbohydrate, dairy products, detergent and surfactant, organic and inorganic compound etc.

2. Working Principle:
After being filtrated and heated, the hot air enters the air distributor uniformly on the top of the drying room. The hot air is in spiral form.
Liquid material will be sprayed into extremely fine liquid beads like fog through the spraying nozzle on top of the drying tower.
After contacting the heated air, in very short time, the moisture vaporizes rapidly; the liquid material is fully dried into final products.
The final products will be discharged continuously from the bottom of the cyclone separator. And the waste gas will be discharged from blower.

3. Features:
(1) Quick drying speed, the surface area of liquid material after atomizing is increased greatly. In the flow of hot air, 95~98% moisture in liquid material can be evaporated at the very moment. The time of drying is only in several seconds. Especially fit for drying heat sensitive materials.
(2) Final product has good uniformity, fluidity, flowability, solubility, high purity, and good quality.
(3) Easy to control and operate.
(4) Liquid material with moisture of 0~60% (special material may reach 90%) can be dried to powder or granule only once.
(5) No need to crush or separate the final products after drying. So it reduces productive procedure and raises the purity of final products.
(6) The particle size, stacking density and moisture content of final product can be adjusted within certain scope through exchanging operation condition.

Product Description

INTRODUCTION
Spray drying is a most widely used craft in liquid molding process and drying industry. It is ideal for producing powdery and granular solid product from the solution, emulsions, soliquoid and pumpable paste states. Thus, when the particle size distribution, residual moisture content, bulk density and particle shape must meet a precision standard, the spray drying is an ideal choice.

WORKING PRINCIPLE
Filtered and heated air goes into air distributor on the top of the dryer, and spirals into drying room uniformly. Going through the high-speed centrifugal atomizer on the top of tower, the liquid (rotates) sprays into extremely fine mist liquid beads, and can be dried completely in a short time in co-current contact with hot air. Finished products exhaust continuously from the bottom of the drying tower and cyclone separator, while waste gases are vented by the fan. 

FEATURES
1. Fast drying speed; greatly increasing the surface area of the material after the liquid is atomized; it can instantly evaporate 95% -98% of water in the stream of hot air; it takes only a few seconds to complete drying, which is especially suitable for drying heat sensitive materials. 
2. Our products have a good uniformity, mobility and solubility, high purity and good quality.
3. Simplified production process, easy to operate and control. Liquid of 40-60% moisture content (up to 90% for special materials) can be dried into powder products at a time, without crushing and screening after drying, which reduces production process and improve product purity. The size, bulk density, moisture can be adjusted within a certain range by changing operation conditions. It is convenient to do control and management. 

APPLICATION
Chemical industry: sodium fluoride (potassium), alkaline dyestuff and pigment, dyestuff intermediate, compound fertilizer, formaldehyde silicic acid, catalyst, sulphuric acid agent, amino acid, white carbon black, etc.
Plastic resin: AB, ABS latex, urea resin, phenolic resin, dense glue (urea) formaldehyde resins, polyethylene, polyvinyl chloride, etc.
Food industry: fat-rich milk powder, lancet protein, cocoa milk powder, babymeal, hunting blood meal, egg white (yellow), etc.
Food and plants: oats, chicken juice, coffee, instant tea, seasoning meat, protein, soybean, peanut protein, hydrolyzate and so on.
