Based on our 20-year experience in the drying industry of tobacco, fruits and vegetables, medicinal materials, food, and aquatic products, and in combination with the three-dimensional flow aerodynamic design technology of aviation engines, we have developed a series of pressurized axial flow fans for drying, featuring large fan flow, high dynamic and static pressure, stronger penetration, longer conveying capacity, uniform temperature, high efficiency, and low noise. It can greatly improve the airflow effect and effectively solve problems such as uneven wind conditions before and after materials, blind areas in the middle of ventilation, and slow drying speed. In terms of structure, performance, and installation design, the high-efficiency pressurized axial flow fan highlights the following characteristics:
The booster fan optimizes the perfect match between the rectifying stationary blades and the operating moving blades on the basis of a general-purpose fan.
2. The pressurized stationary blade converts a portion of the kinetic energy consumed by the rotating blade into static pressure through channel expansion.
3. The rotating air flow generated by the work of the moving blades is converted into an advection air flow, which enhances the dynamic pressure delivery capacity and extends it further (the relationship between the air volume delivery distance and the dynamic pressure Pd= ρ* V ²/ 2)。
4. Due to the change in the airflow direction of the booster fan, the airflow directly passes through the middle of each layer of material, with a uniform flow rate that is not easily blocked, and a small kinetic energy loss.
5. The motor adopts a dedicated fan motor, with the power cord led out at the rear end to reduce airflow resistance and increase flow; Driven by high flow rate, high dynamic pressure, and static pressure, it has stronger penetration, longer air supply distance, more uniform temperature, high efficiency, and low noise.
6. Installation method of this type of fan: pipe type, square type, fixed type, simple and practical structure.
7. The fan design is perfectly matched by a dedicated motor, air collector, rectifying stationary blades, and moving impeller. It has a beautiful appearance, short axial dimensions of the fan, and is convenient for user installation and maintenance. Compared with general-purpose fans, this type of fan reduces noise by 3% and improves static pressure efficiency by more than 30%. According to the drying requirements of different materials, industries, and environments, three series of fans have been designed: ZYF crop drying series, BKF all stainless steel series, and CBF explosion-proof series for customers to choose from.

Application:

This series of fans are widely used in the drying equipment supporting industries such as economic crops, tobacco, medicinal materials, and wood, providing heat source transmission for batch drying and drying materials, making the temperature in the drying room more uniform, drying time shorter, and saving energy consumption, achieving synchronous drying of materials in the drying room, and improving the quality of drying materials.

This high-efficiency pressurized axial flow fan for drying is suitable for any working condition in the drying industry, avoiding the selection dilemma for users. Beautiful appearance, short axial size of air duct, making installation and maintenance more convenient and applicable for users.
