Spray dryer for Chinese herbal extractsworking principle

The air passes through the filter and heater, enters the air distributor at the top of the dryer, and the hot air enters the dryer uniformly in a spiral shape. The material liquid is pumped from the material liquid tank to the centrifugal atomizer at the top of the dryer through a filter, causing the material liquid to spray into extremely small mist droplets. The material liquid and hot air come into contact in parallel, and the moisture evaporates rapidly, drying into finished products in a very short time. The finished products are discharged from the bottom of the drying tower and the cyclone separator, and the exhaust gas is discharged by the fan.
Users can choose the heating method, dust collection method, and dust removal method according to their actual situation.

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 on the top of the tower body, and (rotating) spray into extremely 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.
Spray dryer for Chinese herbal extractsfeature
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 the processing air for the dryer.
3. The production process is simplified and suitable for continuous control of production. Liquids with a moisture content of 40-90% can be dried into powder in one go, reducing the need for 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, and the particle size, looseness, and moisture content of the product can be adjusted within a certain range.

Several common onesCentrifugal spray dryer:
① DIS series high-speedCentrifugal spray dryer
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.
② LPG series high-speedCentrifugal spray dryer
LPG high-speed centrifugal spray dryer is a kind of drying equipment suitable for emulsion, suspension, paste, solution and other liquids. 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.
③ LGZ series high-speed
LGZ series high speed can dry solutions, lotion, suspensions, paste 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.
