SUS304 or 316L high-speed centrifugal spray dryer, suitable for uniform and pure

Product Specification

Advanced Spray Drying Machine for Uniform and Pure Heat-Sensitive Products

PRODUCT DESCRIPTION:

Spray drying is a widely used process in the liquid process forming and drying industry. It is suitable for producing powdery and granular solid products from solutions, emulsions, suspensions and paste liquid raw materials. Therefore, spray drying is a better process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet certain standards.

working principle:

The air is filtered and heated and enters the air distributor at the top of the dryer. The hot air enters the drying chamber in a spiral shape evenly. The liquid material passes through the high-speed centrifugal atomizer at the top of the tower and is (rotated) sprayed into extremely fine mist-like droplets, which can be dried into finished products in a very short time when contacted with hot air in parallel flow. The finished product is continuously output from the bottom of the drying tower and the cyclone separator, and the waste gas is exhausted by the fan.

Performance characteristics:

The drying speed is fast. The surface area of the liquid material is greatly increased after atomization. In the hot air flow, 95%-98% of the water can be evaporated in an instant. It only takes a few seconds to complete the drying. It is especially suitable for drying heat-sensitive materials.
◎The product has good uniformity, fluidity and solubility, and the product has high purity and good quality.
◎The production process is simplified and the operation and control are convenient. Liquids with a moisture content of 40-60% (up to 90% for special materials) can be dried into powder products at one time. There is no need to crush and screen after drying, which reduces the production process and improves product purity. The product particle size, bulk density, and moisture content can be adjusted within a certain range by changing operating conditions, and 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 agents, amino acids, white carbon black, etc.
Plastic resin: AB, ABS emulsion, urea-formaldehyde resin, phenolic resin, sealant (urea) formaldehyde resin, polyethylene, polyvinyl chloride, etc.
Food industry: fat-rich milk powder, protein, cocoa milk powder, milk replacer powder, blood hunting powder, egg white (yellow), etc.
Food and plants: oats, chicken juice, coffee, instant tea, spiced meat, protein, soybeans, peanut protein, hydrolysates, etc.
Sugars: corn steep liquor, corn starch, glucose, pectin, maltose, potassium sorbate, etc.
Ceramics: alumina, ceramic tile materials, magnesium oxide, talcum powder, etc.

Technical specification:

Note: The amount of water evaporation is related to the characteristics of the material and the hot air inlet and outlet temperatures. When the outlet temperature is 90℃, the water evaporation curve is shown in the figure above (for model selection reference). As the product is constantly updated, the relevant parameters will change without prior notice.
