Product Description
Spray dryer is a kind of continuous atmospheric pressure dryer, which sprays liquid materials into mist with equipment to dry them in contact with hot air. It is used to dry some heat sensitive liquids, suspensions and viscous liquids, such as milk, eggs, tannins and drugs. It is also used for drying fuels, intermediates, soap powder, and inorganic salts.
operational principle
The air is filtered and heated before entering the top air distributor of the dryer, and the hot air enters the drying chamber uniformly in a spiral shape. The feed liquid passes through the high-speed centrifugal atomizer at the top of the tower body, and the (rotating) spray becomes a very fine mist like liquid bead, which can be dried into finished products in a very short time in parallel with the hot air. The finished products are continuously output from the bottom of the drying tower and the cyclone separator, and the waste gas is discharged by the induced draft fan and connected to the water film dedusting.
Basic classification
Centrifugal spray dryer
Product Introduction
High speed centrifugal spray drying is widely used in liquid forming and drying industries.
It is suitable for generating powder and granular solid products from solution, lotion, suspension and paste liquid raw materials. Therefore, spray drying is an ideal process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet accurate standards.
Performance characteristics
The drying speed is fast, and the surface area of the material liquid greatly increases after atomization. In the hot air flow, most of the water can be evaporated instantly, and the drying time is only a few seconds. It is especially suitable for drying thermosensitive materials.
The product has good uniformity, fluidity, and solubility, high purity, and good quality.
The production process is simplified and the operation and control are convenient. For liquids with a moisture content of 40-60% (up to 90% for special materials), they can be dried into powder products in one go, making control and management very convenient.
Adapt to materials
Chemical industry: sodium fluoride (potassium), alkaline dye pigments, dye intermediates, composite fertilizers, formaldehyde silicic acid, catalysts, sulfuric acid agents, amino acids, white carbon black, etc.
Plastic resin: AB, ABS lotion, urea formaldehyde resin, phenolic resin, sealant (urea) formaldehyde resin, polyethylene, PVC, etc.
Food industry: Rich fat milk powder, gluten, cocoa milk powder, milk substitute powder, blood hunting powder, egg white (yolk), etc.
Food and plants: oats, chicken juice, coffee, instant tea, spice meat, protein, soybean, peanut protein, hydrolysate, etc.
Carbohydrates: corn syrup, corn starch, glucose, pectin, maltose, potassium sorbate, etc.
Ceramics: alumina, ceramic tile materials, magnesium oxide, talc powder, etc.
