Stevia Extract 100℃ Air Out Pilot Scale Spray Dryer

Stevia Extract Spray Drying Technology with water cooling jacket

Descriptions

Chinese herbal medicine extract is refined from root, stem and leaves of plants, and contains high sugar which is easy melted at high temperature. Normal centrifugal spraying cannot meet these drying requirements, so we organized a group of technicians to develop such a dryer which specialize in Chinese herbal medicine extract through repeated calculations and many tests basis on our experience to make spraying dryer and collect advantages of same line of dryers from domestic and abroad.

Working principle

Original liquid would be feed by Peristaltic Pump from vessel, and become spray under High Speed Atomizer, the atomizer would be driven by Compressed Air, Atomizing Disc diameter can reach 25000rpm at most. Peristaltic Pump Flow can be adjusted and stable, which can ensure FEEDING STABLY and CONTROL TEMPERATURE EFFECTIVELY.

The new air would be filtered according to Pre-filter and Mid-filter, then start to heat by ELECTRICITY, until inlet air temp. reach 300~350C(depend on actual need). After this, the heated air would be enter the Spray Chamber uniformly, with the help of Spiral-type Hot-air Distributor on the cover. After hot air touch with Spray(materials), water can be evaporated very fast, fine and dry powder can be collected by Cyclone Separator. All adopt SS304.
