Manganese Sulfate Spin flash dryer

Descriptions

The YIBU  Flash Dryer is a pneumatic system primarily used to dry products requiring the removal of free moisture. Drying takes place in a matter of seconds. 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.

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.

For even greater thermal efficiency and where inertisation is required, recycling of exhaust gases can be used. This can be implemented on all our airstream drying systems and retrofitted on customer's existing drying operations.

Many of the largest dryers in the world are flash dryers - some exceeding 20 tons of water evaporation per hour in a single system. Inlet air temperature ranges from 200- 1400°F (100oC -650oC) while airflows can exceed 120,000 cfm (200,000 m3/hr).

Flash dryers have been used to dry products in many industries including food, chemical, mineral and polymer. A broad range of feed materials including powders, cakes, granules, flakes, pastes, gels, and slurries can be processed. For slurries, pastes, or sticky materials, backmixing of the wet feed with a portion of dry product to produce a suitable conditioned material is required.

This technology can also be used for cooling applications.

Principle

The hot air enters into the bottom of the dryer in tangent direction. Under the driving of the stirrer, a powerful rotating wind area is formed. The paste state materials enter into the dryer through the screw charger. Under the powerful effect of stirring at high-speed rotation, the materials are distributed under the function of strike, friction and shearing force. 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 hot-air flow. The grading rings will stop and keep the big particles. Small particles will be discharged out of the dryer from the ring center and will be collected in the cyclone separator and dust collector. The not-fully-dried or big piece materials will be sent to the wall of the equipment by centrifugal force and be smashed again after they fall down to the bottom.

Features

1.This machine combines the whirl technology with the fluidity, ejection and smashing step technologies.
2.The equipment is compact and small in size, high in production efficiency and continuous in the production. It has                            realized that  small equipment can perform the large production.
3.The drying capacity for this machine is big but its energy consumption is low. Its heat efficiency is high.
4.The material stay time is very short. The quality of the final products is very good. The machine can be used for drying the heat sensitive materials.
5. 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.
