XSG Series Rotating Flash Dryer (Spin Flash Dryer)

1. The collection rate of finished product is very high.
To adopt cyclone separator with high efficiency and low resistance (the collection rate can be above 98%), together with air chamber type of pulse cloth bag deduster(the collection rate can be above 98%).
2. To control final water content and fine of finished product efficiently.
To control final water content and fine of finished product through adjusting screener and inlet air speed.
3. No materials stick on the wall
Continuous high-speed air flow washes out the materials stayed on the wall strongly in order to clear the phenomenon that materials stay on the wall.
4. This machine is good at processing thermal sensitive materials.
The bottom of main machine belongs to high temperature area. The air speed in this area is very high, and the material can hardly contact heat surface directly, so there is no worry about burning and color changing.
5. QUANPIN Spin Flash dryers are designed for continuous drying of cohesive and non-cohesive pastes and filter cakes, as well as high-viscosity liquids. The main components in an QUANPIN Spin Flash plant are a feed system, the patented drying chamber and a bag filter. Widely acclaimed by customers in a variety of industries all over the world, this patented process provides a faster and more energy-efficient alternative to spray drying. With more than 150 QUANPIN Spin Flash dryer installations world-wide QUANPIN DRYING combines experience and cutting-edge technology into added-value solutions for our customers. Elevated drying temperatures can be used with many products since the flashing off of surface moisture instantly cools the drying gas without appreciably increasing the product temperature which may damage its quality.
6. Wet material is dispersed into a stream of heated air (or gas) which conveys it through a drying duct. Using the heat from the airstream, the material dries as it is conveyed. Product is separated using cyclones, and/or bag filters. Typically, cyclones are followed by scrubbers or bag filters for final cleaning of the exhaust gases to meet current emission requirements.
7. The feed system consists of a feed vat where a discontinuous flow of product is buffered and fragmented by an agitator prior to continuous drying. A variable speed feed screw (or pump in the case of fluid feed) forwards the product to the drying chamber.
8. The rotor at the conical base of the drying chamber fluidizes product particles in a drying-efficient hot air flow pattern in which any wet lumps are rapidly disintegrated. Hot air is supplied by a temperature-controlled air heater and speed-controlled fan, entering the drying chamber at a tangent in order to establish a turbulent, whirling air flow.
9. Airborne, fine particles pass through a classifier at the top of the drying chamber, while larger particles remain in the air flow for further drying and powdering.
10. The drying chamber is rigidly designed to withstand pressure shock in the event of explosive combustion of flammable particles. All bearings are effectively protected against dust and heat.
