SXG Spin Flash Drying Machine

Principle

SXG Spin Flash Drying Machine: The hot air enters into the bottom of the drier in tangent direction. Under the driving of the stirrer, a powerful rotating wind field is formed. The paste state materials enter into the drier through the screw charger. The block state materials will soon be smashed and contact the hot air fully and the materials are heated and dried. The dried materials after the de-watering will go up with the heat-air flow. The step rings will stop and keep the big particles. Small particles will be discharged out of the drier from the of the equipment by centrifugal force function and be smashed again after they fall down to the bottom.

SXG Spin Flash Drier Description:

This SXG Spin Flash Drying Machinery combines the whirl technology with the fluidity. Ejection and smashing step technologies. The equipment is compact and small in size, high in production efficiency and continuous in the production. It has realized that a small equipment can perform the large production. The drying capacity for this machine is big but its energy consumption is low. Its hear efficiency can go up to more than 70%. The material star time is very short. The quality of the final products is very good, The machine can be used for drying the heat sensitive materials. For the negative pressure or the micro-negative pressure operation, the machine is good for its tightness and high in the efficiency so as to eliminate the environmental Pollution.

Feature
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 duster(the collection rate can be above 99.9%)
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. 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.
6. 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.
7. 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.
8. 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.
9. 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.
