Brief introduction of flash drying equipment

The flash drying equipment is a vertical fluidized bed drying equipment with a rotating crushing device. Its main body is a cylindrical drying chamber, which is composed of a crushing fluidization section at the bottom, a middle drying section and a top classification section. Complete operations such as crushing, drying and grading of materials. In addition, there are heaters, feeders, mixing and crushing systems, classifiers, drying main pipes, cyclones, bag filters, fans and other components.

work principle 

The hot air enters the agitating and crushing drying chamber from the bottom of the dryer at an appropriate spraying speed from the inlet pipe diameter, and rises in a spiral shape. Strong shearing, floating, and rotating effects are produced, so the material is micro-materialized by centrifugation, shearing, collision, and friction, which enhances the mass and heat transfer. At the bottom of the dryer, the larger and wetter particles are mechanically broken under the action of the agitator, the moisture content is lower, and the particles with smaller particle size are entrained by the airflow to rise, and are transported to the separator for gas-solid separation, and the finished product is collected and packaged. , And the exhaust gas is emptied after being treated by the dust removal device.

Features

   1. The organic combination of swirling, fluidization, spouting and crushing classification technology.

   2. The equipment is compact, small in size, high in production efficiency, continuous production, realizing "small equipment, large production".

   3. High drying intensity, low energy consumption and high thermal efficiency.

   4. The material residence time is short, the finished product is of good quality, and it can be used for drying heat-sensitive materials.

   5. Negative pressure or micro-negative pressure operation, good airtightness, high efficiency, eliminating environmental pollution
