Vibrating Fluid Bed Dryer

In modern industrial production, drying is an indispensable key link in many industries, from chemical, food, medicine to agriculture, etc., there are extremely high requirements for the efficiency, quality and energy consumption of material drying. As a high-efficiency and energy-saving drying equipment, vibrating fluid bed dryer dryer occupies an important position in the field of industrial drying with its unique working principle and significant performance advantages.

The vibrating fluid bed dryer dryer is a new type of drying equipment that combines mechanical vibration and fluidization technology. Its working principle is based on the fluidization phenomenon. When the gas passes through the particle bed at a certain speed, the particles will be suspended in the airflow and present a fluid-like state, which is called fluidization. In the vibrating fluid bed dryer dryer, after the material enters the equipment, the hot air under the distribution plate passes upward through the distribution plate at a suitable speed, so that the material particles are fluidized under the action of the hot air.

At the same time, the vibration motor at the bottom of the equipment generates an exciting force, which makes the whole equipment vibrate in a certain direction. This vibration makes the material jump forward in a specific direction in the dryer on the basis of fluidization. The hot air is in full contact with the material, and a strong heat and mass transfer process is carried out. The moisture in the material is continuously evaporated and taken away by the hot air, thereby achieving the drying of the material. The introduction of vibration not only helps the uniform mixing and conveying of the material, but also effectively reduces the agglomeration of the material during the drying process, and improves the drying efficiency and drying quality.

The synergistic effect of vibration and fluidization makes the residence time of materials in the equipment more uniform and controllable, avoiding the problems of local overheating or insufficient drying, and can meet the drying process requirements of different materials.

Main body

The main body is the main structure of the vibrating fluid bed dryer dryer, usually made of high-quality metal materials with good strength and corrosion resistance. A distribution plate is set inside the main body. The function of the distribution plate is to evenly distribute the hot air so that the material can be evenly fluidized. There are many regularly arranged small holes on the distribution plate, and the aperture size and distribution density are designed according to different material characteristics and drying processes. The shape and size of the main body are customized according to actual production needs to ensure that the material has enough drying space and a reasonable movement path in the equipment.

Vibration system

The vibration system is the power core of the equipment and consists of a vibration motor and a transmission mechanism. The vibration motor generates an exciting force through the high-speed rotation of the eccentric block to drive the material to move in the dryer. Its vibration frequency and amplitude can be flexibly adjusted according to the drying needs: when processing high-humidity materials, increasing the frequency and amplitude can speed up the material advancement speed and enhance the contact efficiency with the hot air; when processing heat-sensitive materials, the parameters need to be reduced to avoid material damage. The advanced vibration system is also equipped with an intelligent adjustment device that can automatically optimize the parameters according to the material state to achieve intelligent drying.

Shock absorption system

The shock absorption system is an important guarantee for the stable operation of the equipment. It is mainly composed of spring shock absorbers and dampers, and is installed between the main body and the foundation. The spring shock absorber buffers the impact of the exciting force on the foundation through elastic deformation, effectively reducing the equipment operation noise and vibration transmission; the damper further consumes vibration energy, suppresses resonance, and maintains the stability of the main body. A good shock absorption system can not only extend the service life of the equipment, reduce mechanical wear and failure risks, but also improve the working environment and reduce the impact on surrounding equipment and buildings.

(I) High drying efficiency

The vibrating fluid bed dryer dryer combines vibration and fluidization technology to make the material fully contact with hot air, greatly improving the efficiency of heat and mass transfer. The material jumps forward in the bed, the movement state is more active, it can quickly absorb heat, and the water evaporates quickly, thus shortening the drying time and improving production efficiency.

(II) Good drying quality

Since the material can be evenly fluidized and mixed in the vibrating fluid bed dryer dryer, the contact between hot air and the material is more uniform, avoiding the problem of local overheating or insufficient drying of the material, and ensuring the uniformity of material drying. At the same time, the effect of vibration reduces the agglomeration of the material, so that the dried material has good looseness and particle size distribution, and the product quality is significantly improved.

(III) Significant energy-saving effect

The energy-saving characteristics of the vibrating fluid bed dryer dryer are mainly reflected in two aspects. On the one hand, due to its efficient heat and mass transfer performance, it can achieve rapid drying of materials at a lower temperature, reducing energy consumption. On the other hand, the reasonable design of the vibration system makes the equipment consume less energy during operation, the power of the vibration motor is relatively small, and the spring shock absorber can effectively reduce energy loss.

(IV) Convenient operation and maintenance

The structure of the vibrating fluid bed dryer dryer is relatively simple, the operation interface is intuitive, and the operator can master the operation method of the equipment after simple training. In terms of maintenance, the various components of the equipment are easy to disassemble and install, and are convenient for cleaning and maintenance. The vibration motor, spring shock absorber and other wearing parts are easy to replace, and the maintenance cost is low.

(V) Strong adaptability

The vibrating fluid bed dryer dryer is suitable for drying various types of materials, including materials in different forms such as granular, powdery, and flake. By adjusting the structural parameters and process parameters of the equipment, such as the aperture of the distribution plate, vibration frequency, amplitude, hot air temperature and flow rate, the drying process requirements of different materials can be met. Whether it is low-temperature drying of heat-sensitive materials or rapid drying of high-humidity materials, the vibrating fluid bed dryer dryer can show good adaptability.

(I) Chemical industry

In the chemical industry, vibrating fluid bed dryer dryers are widely used for drying various chemical raw materials and products. Chemical materials often have different chemical properties and drying requirements. With its good adaptability and drying effect, vibrating fluid bed dryer dryers can meet the diverse drying needs of the chemical industry and ensure the stability of product quality.

The food industry has extremely high hygiene standards and quality requirements for material drying. Vibrating fluid bed dryer dryers can effectively retain the nutrients, color and flavor in food, meeting the strict requirements of the food industry for product quality. At the same time, the equipment is made of food-grade materials, meets hygiene standards, and is easy to clean and disinfect, which can effectively prevent food from being contaminated during the drying process and ensure food safety.

(III) Pharmaceutical industry

The pharmaceutical industry has extremely strict requirements on the quality and safety of material drying. The precise temperature control and uniform drying effect of the vibrating fluid bed dryer dryer can ensure that the drugs do not undergo chemical changes and quality variations during the drying process, thereby ensuring the efficacy and safety of the drugs. In addition, the equipment has good sealing performance, which can prevent the material from being contaminated by the outside world during the drying process, and meets the requirements of Good Manufacturing Practice (GMP) for pharmaceutical production.
