Working Principle of Spray Drying Machine
After filtering and heating, the air is blown into air distributor that is on the top of drying machine. The hot air in spiral form equably enters the drying chamber. At the same time, liquid raw materials pass through the high-speed centrifugal sprayer on the top of machine, moreover they are rotated and sprayed into the extreme slim mist liquid beads. So the evenly and swirly distributed hot air completely contact with raw materials. In several seconds, the materials will be dried into powder and discharged continuously from bottom of the drying tower.

Spotlight of Fruit Powder Dryer Machine

1. Drying speed is fast: due to enlarged surface of the material, 95%-98% of water can be evaporated instantly in several seconds. It is more suitable for drying thermal sensitive materials to maintain color, smell and taste of raw materials.
2. High quality final products: finished products featured with high-purity, good uniformity, good flow capability and solubility advantages.
3. Simple and stable operation, convenient to control and debug, easy to achieve automatic operation.
4. It is easy to replace main parts and adjust material staying time. Besides fruit powder, it is suitable for chemical industry, plastic resins, food industry, ceramics and so on.
5. Suitable for large scale food powder drying production. For small scale food drying, you’d better choose small hot air circulation drying oven.

Main Parts of Powder Drying Machine
1.Feeding system
♦ Feeding pump is to keep feeding smoothly
♦ Atomizer is driven by motor directly with variable frequency control and imported bearings. Atomizer can make slurry vaporific continuously and evenly, and enlarges the superficial area for heat exchange with hot air.
♦ Induced draft fan can help remove water steam out.
2.Air processing system
It adopts primary filter and medium efficiency filter to ensure that the air used for drying is the clean and filtered air.
3. Drying system
Drying chamber consists of hot air volute, hot air distributor, air disperser, inner tower body, outer tower body, tower frame, discharge pipe, thermal insulation material, observing and clean door, lamp hole and etc..
4. Material collecting system
The first cyclone separator can collect 80% powder and the other 19.8% can be collected by the second cyclone separator. The total collecting rate can be up to 99%.
5.Electric controller: start the motor stably

Note: If you need small sized spray dryer for laboratory, we can supply you too. Here is the Video of small spray dryer.
