Description:
A spray dryer is a device used to produce a dry powder from a liquid or slurry by rapidly drying with a hot gas. The basic principle involves atomizing the liquid feed into fine droplets using a nozzle or rotary atomizer. These droplets are then introduced into a drying chamber, where they come into contact with a hot gas, usually air. The hot gas quickly evaporates the moisture from the droplets, resulting in the formation of dry particles. The dry particles are separated from the drying gas in a cyclone or a bag filter and collected at the bottom of the chamber. The final product is a free-flowing powder. Spray drying is widely used in various industries, including food, pharmaceuticals, and chemicals, due to its ability to produce uniform and fine particles, retain product quality, and
achieve efficient drying.

Advantages of Spray Dryers:
1.Fast Drying: The large surface area of the fine droplets allows for rapid moisture evaporation.
2.High-Quality Product: Maintains the color, flavor, aroma, and nutritional content of the material, suitable for heat-sensitive materials.
3.Flexible Operation: Parameters such as feed rate and hot air temperature can be adjusted to control the moisture content and particle size of the product.
4.Continuous Production: Suitable for large-scale continuous production with a high degree of automation.
5.PLC control system, make your research more easier and efficient.
6.Narrow size distribution, more than 95% of the dry powders are in the same range of particles.
7.In the hot-air flow, 95%~98% of water can be evaporated at a moment. You can finish material drying only in several seconds.
8.Self-priming peristaltic pump, avoid secondary pollution, make sure whole process conducted steady & smoothly.
9.Stainless steel material, arc corner design and polyester powder coated shell, prevents corrosion of acidity and alkaline air effectively.
Applications:
Food Industry: Such as milk powder, egg powder, juice powder, etc.
Pharmaceutical Industry: Such as antibiotics, vitamins, herbal extracts, etc.
Chemical Industry: Such as dyes, pigments, catalysts, etc.
