Description

As a professional fluidized bed dryer manufacturer, Yutong provides vertical fluidizing dryer and high efficiency boiling dryer for your selection. The heated and filtered air is guided into by the draught fan and passed through the screen plate of the hopper. In the working room, the air forms to fluidization state through mixing and negative effect. The moisture will be quickly evaporated and removed, and the materials can be rapidly dried.

Brief Description:

In the fluidized bed drying process, the bulk material is placed on the orifice plate, and the gas is transported from the lower part thereof, causing the material particles to move on the gas distribution plate, and is suspended in the gas flow, thereby generating a mixed bottom layer of the material particles and the gas, as if The liquid boils like. In the fluidized bed dryer, the material particles are in full contact with the gas in the mixed bottom layer to conduct heat transfer and moisture transfer between the material and the gas.

Principle:

If the gas passes through a bed of particles, the bed will assume a different state as the velocity of the gas changes. At lower flow rates, the gas flow only flows through the gaps of the stationary particles, which is called a fixed bed. When the airflow velocity increases to a certain value, all the particles are suspended by the rising airflow. At this time, the force of the gas against the particles is balanced with the gravity of the particles, and the bed reaches the initial fluidization. For minimum fluidization speed. When the velocity of the gas exceeds this value and exceeds the terminal velocity (maximum fluidization velocity) of the particle, the interface on the bed disappears and entrainment occurs, and the solid particles are carried out with the fluid from the bed. This is the pneumatic transport of solids. Particle phenomenon, or a fluidized bed of dispersed phase.

Application

Fluidized bed drying has high heat transfer and mass transfer rate, high drying rate, high thermal efficiency, compact structure, low basic investment and maintenance cost, and easy operation. Therefore, fluidized bed dryers are widely used in the chemical, food, ceramics, pharmaceutical, polymer and other industries.

 

In order to ensure our quality requirements are maintained, we implement the ISO9001 quality management system, purchase our raw materials from reliable suppliers, continue to introduce advanced equipment, and employ highly skilled staff. The quality of our equipment is repeatedly checked during each stage of production.

In addition, all machines must undergo a trial run in the workshop, and only those qualified products are allowed to leave our factory. Due to their consistent quality, Yutong drying machines, mixing machines and grinding machines have been awarded many honors, including Recommendation for High-quality Products by IQAC and Recommended Products for International Trade by the U.S. Asia Economic Trade Cooperation Committee.
