product description:
Spray drying is a widely used process in the liquid process forming and drying industry. Zui is suitable for the production of powdered, granulated or lumpy solid products from solutions, emulsions, suspensions and plastic paste liquid materials. Therefore, when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet the exact standards. Spray drying is an ideal process.
working principle:
The air is filtered and heated into the air distributor at the top of the dryer, and the hot air enters the drying chamber in a spiral shape evenly. The liquid is sprayed into a very fine misty liquid droplet through a high-speed centrifugal atomizer at the top of the tower body, and it can be dried into a finished product in a short time by cocurrent contact with hot air. The finished product is continuously outputted from the bottom of the drying tower of the LPG series high-speed centrifugal spray dryer and the cyclone, and the exhaust gas is exhausted by the fan.
Features:
The drying speed is fast, the surface area of ​​the liquid is greatly increased after atomization, and in the hot air flow, 95%-98% of the water can be evaporated instantaneously, and the drying time is only a few seconds, which is especially suitable for the drying of heat sensitive materials.
LPG series high-speed centrifugal spray dryer products have good uniformity, fluidity and solubility, high purity and good quality.
The production process is simplified and the operation control is convenient. For liquids with a moisture content of 40-60% (up to 90% of special materials), it can be dried into a powder product at one time. After drying, no pulverization and screening are required, which reduces the production process and improves the purity of the product. The particle size, bulk density and moisture of the product can be adjusted within a certain range by changing the operating conditions, and the control and management are very convenient.
Application range:
* Chemical industry: sodium fluoride (potassium), basic dyes, dye intermediates, compound fertilizers, formaldehyde silicic acid, catalysts, sulfuric acid agents, amino acids, white carbon black, etc.
* Plastic resin: AB, ABS emulsion, urine aldehyde resin, phenolic resin, dense (urea) formaldehyde resin, polyethylene, polyvinyl chloride and so on.
* Food industry: rich fat milk powder, scorpion, cocoa milk powder, milk replacer powder, blood test powder, egg please (yellow) and so on.
* Food and plants: oatmeal, chicken juice, coffee, instant tea, flavored meat, protein, soy, peanut protein, hydrolysate, etc.
* Sugar: corn syrup, corn starch, glucose, pectin, maltose, potassium sorbate, etc.
* Ceramics: alumina, ceramic tile, magnesia, talcum powder, etc.
