Overview of high-speed centrifugal spray drying machine

Spray dryer, spray drying tower is the most widely used technology in liquid forming process and drying industry. It is most suitable for producing powdery and granular solid products from suspended emulsion, solution, emulsion and paste liquid raw material. Therefore, the spray dryer is an ideal drying process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product meet precise standards.


1, hot air and droplet contact: a sufficient amount of hot gas flow into the spray drying chamber, you must consider the direction and angle of the heat flow, whether it is a flow, countercurrent or mixed flow, to ensure full contact with the droplet, in order to carry out adequate heat exchange.

2, atomization: Spray dryer atomization System must ensure that the droplet size distribution evenly, this is crucial. Because of this can ensure the quality of products qualified rate.

3, the pipe angle and the cone angle design: We have obtained some experience data from the production of nearly thousand sets of spray drying unit, can share with everybody.


1, spray dryer speed, material liquid after atomization, surface area greatly increased, in contact with hot air, an instant can evaporate 95%-98% of the water, drying time only a few seconds, especially for the drying of heat-sensitive materials.

2, the product has a good uniformity, fluidity and solubility, the higher the product purity, good quality.

3. The production process of spray drier is simplified and the operation control is convenient. For wet content (special materials up to 90%) of the liquid can be dried into a powder product, after drying do not need to crush and screening, reduce production processes, improve product purity. The product size, pine density, moisture, in a certain range can be changed operating conditions to adjust, control and management are very convenient.

Working principle

The dryer is open cycle, and flow type, centrifugal atomization. Drying medium air through the initial, medium-effect air filter After filtering according to the operation instructions from the blower suction and then through the heater heating through the high-efficiency filter hot air distributor into the spray drying main tower. Liquid material according to the operating instructions through the peristaltic pump, into the high-speed rotating centrifugal nozzle, under the action of centrifugal force is dispersed into small droplets. In the spray drying main tower, small droplets and hot air in full contact, along its specific path after the heat exchange is dried into a product, and then separated by a cyclone, solid materials are collected, the gas medium is filtered and discharged. The whole spray system is easy to clean, without dead angle, and conforms to GMP requirements.

Application scope

Chemical Products: poly aluminum chloride, disperse dyes, reactive dyes, organic catalysts, white carbon black, washing powder, zinc sulfate, silica, sodium silicate, potassium fluoride, calcium carbonate, potassium sulfate, inorganic catalysts, all kinds of waste liquid.

Food: amino acid, vitamin, egg powder, bone meal, seasoning, protein, milk powder, pig blood powder, soy sauce powder, coffee, tea, glucose, Sls acid potassium, pectin, flavor and fragrance, vegetable juice, yeast, starch, etc.
