Spray dryer

The so-called centrifugationSpray dryerIt is one of the widely used drying machines in industrial production, which uses centrifugal atomizers to dry certain liquid materials. Spray drying is widely used in liquid forming and drying industries. It is suitable for generating powdery and granular products in solution, lotion, suspension and pumpable lake liquid raw materials. Therefore, when the particle size distribution, residual moisture content, bulk density and particle shape meet the precise standards, spray drying is a very ideal process.

1、 Working principle:

After filtering and heating, the air enters 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 (rotating) spray into fine mist like liquid beads, which can be dried into finished products in a very short time in parallel 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 discharged by the fan.

2、 Characteristics:

1. The drying speed is fast, the surface area of the material liquid is greatly increased after atomization, and 95% -98% of the moisture can be evaporated instantly in the hot air flow. It only takes 5-15 seconds to complete the drying process and has the characteristic of instantaneous drying.

2. The special air distribution device reduces equipment resistance and effectively provides a processing air outlet for the dryer.

3. The production process is simplified and suitable for continuous control of production. For liquids with a moisture content of 40-90%, they can be dried into powder in one go, reducing crushing, screening and other processes to improve product purity.

4. The material completes the drying process in a short period of time, which is suitable for drying heat sensitive materials and can maintain the color, aroma, and taste of the material.

5. The product has good dispersibility, fluidity, and solubility. The particle size, looseness, and moisture content of the product can be adjusted within a certain range.

3、 Scope of application

1. Food industry: dense milk powder, collagen, cocoa milk powder, lotion substitute, pig blood powder, egg white (yellow), etc.

2. Food and plants: oats, chicken juice, coffee, instant tea, spice meat, protein, soybean, peanut protein, hydrolysate, etc.

3. Carbohydrates: corn syrup, corn starch, glucose, pectin, maltose, potassium sorbate, etc.

4. Plastic resin: AB, ABS lotion, urea formaldehyde resin, phenolic resin, sealant (urea) formaldehyde resin, polyethylene, polyfluoroethylene, etc.

5. Chemical industry: Sodium fluoride (potassium), alkaline dyes and pigments, dye intermediates, compound fertilizers, formaldehyde silicate, catalysts, sulfuric acid agents, amino acids, white carbon black, etc 6 Ceramics: Aluminum oxide, ceramic tile materials, magnesium oxide, etc.

4、 Several Common CentrifugationsSpray dryer:

The DIS series high-speed centrifugation is suitable for industries such as chemical, light industry, food, medicine, building materials, and environmental protection. The organic and inorganic substances in the above solutions, emulsions and pastes are transformed into powdery products of fine and medium particles after passing through the spray drying equipment for a few seconds. Its heat sensitive products can maintain color, fragrance and taste, have good solubility and high purity, shorten processing procedures, improve production efficiency, have no environmental pollution, save energy, and implement automatic continuous production.

LPG high-speed centrifugal drying equipment is suitable for drying liquids such as emulsions, suspensions, pastes, and solutions. In polymers and resins; Fuel and pigments; Ceramics, glass, rust removers, insecticides; Carbohydrates and dairy products; Detergents and surfactants; Fertilizers; Organic and inorganic compound materials perform particularly well in drying.

LGZ series high-speed centrifugation can dry solutions, lotion, suspensions, pasty materials and spray into dry powder with high speed, high efficiency and few processes. It can maintain the color, taste, and aroma of materials, with good dry powder solubility, high purity, and good operating environment. It can be widely used in chemical, petrochemical, metallurgical, food, pharmaceutical, construction, ceramics, forestry and chemical industries through basic automation operations.
