Lab scale spray dryer for R&D

Description of Spray Dryer:

Spray drying is a method of producing dry powder from liquid or slurry materials by rapidly drying with a hot gas. This is the preferred method of drying of many thermally-sensitive materials such as foods, chemicals, feed additives, health products and so on.
Liquid material is pumped into the top installed centrifugal disc atomizer by mono pump and atomized into fine droplets inside the drying chamber. Meanwhile, clean hot air is blown into the air distributor at the same time. The evenly and swirly distributed hot air completely contacts with droplets for heat transfer. The droplets are dried into powder in several seconds and sucked out into the cyclone for discharging via exhaust fan.
LPG-5 lab scale Spray dryer is widely used for R&D  in R&D center and small production in food factory, pharmaceutical factory and chemical factory.

Features of spray dryer:

• The drying speed is high when the material liquid is atomized, the surface area of the material will increase greatly. In the hot-air flow, 95~98% of water can be evaporated at a moment. The time of completing the drying is only several seconds. This is especially suitable for drying the heat sensitive materials.
• Its final products own the good uniformity, flow ability & solubility. And the final products are high in purity and good in quality.
• The production procedures are simple and the operation and control are easy. The liquid with moisture contents of 40~60% (for special materials, the contents might be up to 90%) can be dried into the powder or particle products once a time. After the drying process, there is no need for smashing and sorting, so as to reduce the operation procedures in the production and to enhance the product purity. The product particle diameters, looseness and water contents can be adjusted through changing the operation condition within a certain range.
