Working Principle of FANQUN Vibrating Fluidized Bed Dryer
The vibrating fluidized bed dryer superimposes mechanical vibration on the fluidized bed, allowing the material to complete fluidization, movement and heat exchange during its forward movement at the same time.
The equipment evenly feeds heated air into the bed layer to make the solid particles enter a fluidized state of continuous churning and mutual collision. Meanwhile, its mechanical vibration further helps you handle materials with poor fluidity, prone to caking or high moisture content, avoiding the formation of hot spots, scorched edges or local wet and cold areas. The equipment usually adopts a multi-section structure, enabling operations such as drying, cooling or homogenization to be continuously completed within the same device to increase your overall.
Fluidization: Hot air passes upward from the bottom of the bed through the material layer, causing the particles to suspend and loosen to form a uniform fluidized state.
Vibration: Bed vibration enhances the gas-solid contact area and propels the material forward at the same time. This shortens the drying time and improves the processing stability of difficult-to-fluidize materials.
Drying: As the material advances in the vibrating fluidized bed, hot air removes moisture or solvents from the surface of the particles to achieve a stable and controllable drying effect.
Advantages of FANQUN Vibrating Fluidized Bed Dryer
High-efficiency Heat Transfer
The fluidized bed structure provides a larger contact interface between the material and the air, enabling more thorough heat and moisture exchange. The addition of vibration improves the looseness and renewal speed of the bed layer to offer you higher drying efficiency.
Dry evenly
The combined effect of vibration and airflow makes the material present a stable rolling fluidization state. It can reduce flow deviation or dead corners and help you achieve more stable moisture uniformity and particle quality.
Adjustable
You can flexibly control the material residence time and adjust the vibration frequency, full amplitude, material layer thickness and the height of the circulating weir. The flexible adjustment meets your production requirements for different formulas, particle sizes or target moisture contents.
Small Product Loss
The equipment adopts low-frequency and low-amplitude vibration. Materials move forward gently inside the machine, which causes almost no breakage. It is highly suitable for dealing with fragile particles, modified materials or high-value-added products.
Energy Conservation
Vibration assistance requires lower the fluidization speed for the system, thus resulting in less overall energy consumption. For factories that run continuously for a long time, it can significantly reduce their operating costs.
Easy To Clean
The equipment can take a fully enclosed structure, which effectively decreases dust leakage and cross-contamination. In addition,its simple internal structure, visual Windows and quick-release components enable it to be more convenient for you to carry out daily maintenance and wire replacement cleaning.
Widely Applied
The vibrating fluidized bed dryer is widely used in continuous drying processes such as food ingredients, chemical powders, pharmaceutical intermediates, mineral powders, and new energy materials.
Safer Production
The vibrating fluidized bed’s operating temperature is relatively low, and it avoids the static accumulation of materials on the bed layer. Those lower the risks of coking, caking and combustion, and the overall safety is better.
Auxiliary Function
You can simultaneously implement the drying section and the cooling section within a single device through multi-stage design, which can shorten your process and reduce the floor space.
Types of Vibrating Fluidized Bed Dryer
Horizontal Vibrating Fluidized Bed Dryer
The horizontal vibrating fluidized bed adopts a horizontally arranged bed body, directional vibration and uniform fluidization structure to achieve continuous processing of materials from feeding, drying to discharging. This equipment can handle 50-5000kg/h, meeting the demands from pilot-scale to large-scale continuous production.
Its continuous feeding and discharging design can be directly integrated into your existing production line. The continuous discharging avoids material retention and improves your overall production efficiency.
Vertical Vibrating Fluidized Bed Dryer
The vertical vibrating fluidized bed dryer enables the material to be fluidized and dried layer by layer from top to bottom through a multi-layer or tower structure. Compared to the horizontal one, It saves more than 50% of the floor space and is very suitable for factory layouts with limited space.
Its hot air is utilized in sections from top to bottom, with a thermal efficiency 15% higher than that of the horizontal type and lower energy consumption. Moreover, there is no long-distance transportation so that the material path is shorter, which reduces the wear points and transportation distance, and thus maintenance is more convenient for you.
Continuous Vibrating Fluidized Bed Dryer
The continuous vibrating fluidized bed dryer operates continuously for 24 hours by pairing a closed-loop feeding and discharging system and PLC automatic control. It is particularly suitable for high-output applications.
Its equipment utilization rate exceeds 90% which can satisfy the stability requirements of large-scale continuous production factories. Meanwhile, the control system can keep the fluctuations of key parameters within ±1%, such as temperature, air volume, vibration intensity, and so on.The precise controlling effectively reduces batch differences, and makes the scrap rate as low as below 0.3%.
Intermittent Vibrating Fluidized Bed Dryer
The intermittent vibrating fluidized bed dryer is suitable for you to handle multiple varieties, small batches or high value-added materials. It adopts a batch-type feeding, drying, discharging process, which is flexible for production change and will not affect the next batch.
This machine can be quickly cleaned within 30 minutes after a single batch is completed, suitable for frequent production changes in daily life. In addition, it also has a lower cost. And one person can independently complete the operation, which is very friendly to laboratories, formula development and small-scale trial lines.
Parts of Vibrating Fluidized Bed Dryer
Conveying System
The conveying system is responsible for the full-process conveying of materials from feeding, movement within the bed layer to discharging. Due to its adjustable conveying speed, you can precisely set the residence time of materials in the equipment to ensure thorough and consistent drying, avoiding local over-drying or under-drying.
Vibration System
This system combines an adjustable motor with a vibration mechanism. And it continuously loosens and uniformly fluidizes materials through vibration while simultaneously propelling them forward for stable conveyance.The vibration system can achieve a CV of less than 3% for the fluidization uniformity of the bed material. This effectively avoids caking and bridging, and enhances the capacity to handle materials with moderate viscosity or poor fluidity.
Fluidization System
It is composed of a gas distribution plate and a fluidization regulation component.
Gas distribution plate: It can evenly distribute the hot air flow to the bed layer to keep the material forming a stable fluidized state. Its pore size is usually 50 μm to 5 mm, and the material can be selected as 304/316 stainless steel to provide corrosion resistance and long service life for you.
Pressure regulating valve: The valve maintains a slight positive pressure inside the bed layer. It can prevent outside air from entering, reduce the oxidation risk, and also minimize heat loss at the same time.
Heating System
The heater heats the air or inert gas to the target temperature to offer the drying of the material heat. Its heating range is generally between 40 and 200℃, and thePID temperature control accuracy can reach ±1℃. Supports section temperature control and can match the temperature of different sections according to the characteristics of your materials.
Hot Air System
The hot air distributor is responsible for evenly delivering the heated hot air flow into the bed layer to conduct heat and mass transfer with the fluidized material, while also carrying away the vaporized moisture. It can keep the fluidized bed’s internal temperature stable at all times. The temperature uniformity within the bed layer can be controlled within ±1° C. The optimized hot air path can significantly enhance thermal efficiency and reduce energy consumption.
Separation System
The separator recovers fine powder materials from the exhaust gas and purifies it. This decreases your material waste and also enables the exhaust gas to be discharged up to standard. Common types include cyclone separators, bag filters, solvent recovery devices, and tail gas recovery devices. For high-value powders, the separation efficiency can reach over 99%.
Control system
The control system coordinates the operation of all components to achieve precise control over temperature, wind speed, vibration parameters and conveying speed, with parameter fluctuations controllable within ±1%. This helps you to minimize human errors in actual production, enhance product consistency and traceability.
