LPG series high-speed centrifugal spray dryer

product description
 Spray drying is a widely used process in liquid process shaping and drying industry. It is especially suitable for generating powdery and granular solid products from solutions, emulsions, suspensions and pasty liquid materials. Therefore, when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet high standards, spray drying is a better process.
working principle
  After filtering and heating, the air enters the air distributor on the top of the dryer, and the hot air enters the drying chamber evenly in a spiral shape. The material liquid passes through the high-speed centrifugal atomizer on the top of the tower body, and (rotating) sprays into very fine misty liquid beads, which can be dried into finished products in a very short time in cocurrent contact with hot air. The finished product is continuously output from the bottom of the drying tower and the cyclone separator, and the exhaust gas is evacuated by the fan.
Performance characteristics
◎Simplified production process and convenient operation and control. For liquids with a moisture content of 40-60% (up to 90% for special materials), the liquid can be dried into powder products at one time, without crushing and screening after drying, reducing production procedures and improving product purity. The product particle size, bulk density and water content can be adjusted by changing the operating conditions within a certain range, and the control and management are very convenient.
Adapt to materials
Chemical industry: sodium fluoride (potassium), basic dyes and pigments, dye intermediates, compound fertilizers, formaldehyde silicic acid, catalysts, sulfuric acid, amino acids, white carbon black, etc.
Plastic resin: AB, ABS emulsion, urinary formaldehyde resin, phenolic resin, dense rubber (urea) formaldehyde resin, polyethylene, polyvinyl chloride, etc.
Food industry: fat-rich milk powder, gluten, cocoa milk powder, milk substitute powder, blood hunting powder, egg white (yellow), etc.
Food and plants: oats, chicken juice, coffee, instant tea, flavored meat, protein, soybean, peanut protein, hydrolysate, etc.
Sugars: corn syrup, corn starch, glucose, pectin, maltose, potassium sorbate, etc.
Ceramics: alumina, ceramic tile materials, magnesium oxide, talcum powder, etc.

Technical specifications

Note: The amount of water evaporation is related to the characteristics of the material and the temperature of the hot inlet and outlet. When the outlet temperature is 90oC, the water evaporation curve is shown in the figure above (for reference for selection). As the product is continuously updated, the relevant parameters are changed without prior notice.
