Working principle

Under the entrainment of the hot gas flow, the wet material enters the double cyclone airflow dryer from the tangential direction, and forms a two-way helical motion along the inner wall, and the material is evenly distributed in the airflow. Due to the two-way rotation, the gas boundary layer around the material particles is in a highly turbulent state, which increases the relative velocity and heat transfer area between the gas and the particles, and strengthens the drying process for mass and heat exchange to achieve the purpose of drying.

Performance characteristics

1. The double cyclone air drying equipment has a large processing capacity. The water evaporation capacity is 200kg/h～1500kg/h, especially suitable for drying powder and granular materials with moisture content less than 40%.

2. The equipment occupies a small space. The unique design of the equipment is only one-half of the space occupied by ordinary airflow drying equipment.

3. Continuous operation. Since the drying is completed in a very short time and a few seconds, the material is not overheated, and it is more suitable for active and heat-sensitive materials. Good sealing, no dust leakage.

4. The heat source can be equipped with steam, electric heating, or fuel and coal-fired high-efficiency and energy-saving hot blast stoves.

Scope of application

The double cyclone air drying device is suitable for drying powder and granular materials in the food, chemical, pharmaceutical, building materials, mining and other industries. For example: flour, monosodium glutamate, glucose, soda, feed, bone meal, salt, sugar, slag, mineral salt, plastic resin, synthetic drugs, fertilizers, dyes, cryolite, various additives, etc.

Crafting process

The double cyclone air drying system is mainly composed of a heat source, a feeder, a drying host and a material catcher. The wet material enters the feeder and is sent to the drying chamber. Under the action of the hot gas heated by the heater, it is quickly dried into powder and then enters the trap for collection. The captured material is discharged from the discharge port, and the exhaust gas is discharged by the induced draft fan. outside.
