Flash dryer is an air-flow drying equipment system which integrates the technologies of concentration, swirl, spouting, crushing and classification, and is also called swirl dryer or rotary quick dryer. The following is a detailed introduction to the flash dryer:

First, the working principle

Flash dryer uses air to dry materials, heats the materials above the air temperature, and exchanges heat with flowing air in the dryer to evaporate the water in the materials. At the same time, the material descends under the action of gravity, and the processes of heating, drying and cooling are repeated, and finally the dried material is obtained. The whole drying process usually takes only a few seconds.

Second, the equipment characteristics

High drying efficiency: the flash dryer adopts airflow drying mode, which makes the materials undergo strong heat exchange in a short time, thus quickly removing water.

Simple operation: reasonable equipment design, simple and convenient operation and easy maintenance.

Strong adaptability: Flash dryer is suitable for drying a variety of materials, such as pharmaceuticals, chemicals, pesticides, mining, electronics, dyes, food, pigments and other fields.

Energy saving and environmental protection: the equipment can make full use of heat energy during drying, reduce energy consumption and reduce environmental pollution at the same time.

Third, the scope of application

Flash dryer is widely used in all kinds of material fields that need rapid drying, such as pharmacy, chemical industry, pesticide, mining, electronics, dyes, food, pigments and so on. In pharmaceutical industry, flash dryer is often used to prepare granules, capsules, tablets, etc. In the chemical industry, it is often used to prepare catalysts, pigments, dyes and so on.

Fourth, the method of use

When using the flash dryer, the following steps should be followed:

Turn on the power switch and start the dryer.

Add the materials to be dried into the dryer and distribute them evenly among the layers.

Close the dryer door, start the fan, and draw indoor air into the heating chamber to raise its temperature.

When the temperature of the heating chamber reaches the set value, the drying operation is started.

After the material is dried, close the relevant valves and power supply, open the exhaust valve and discharge the dried material.

Clean the material in the trap and shut down the equipment.

V. Matters needing attention

Before operation, read the instruction manual carefully to understand the equipment structure, working principle and operation method.

Check the running status of the equipment regularly. If any abnormality is found, stop the machine in time for inspection and troubleshooting.

In the process of use, attention should be paid to keep the equipment clean and hygienic to avoid material pollution and blockage.

Operators should have certain professional knowledge and operating skills to ensure the normal operation and safe production of equipment.

To sum up, flash dryer is an efficient, energy-saving and environment-friendly drying equipment, which has a wide application prospect and development potential.
