1. Product Overview:
The granulation spray dryer is a set of granulation spray dryer independently developed by Shanghai Qiaofeng. QFN-ZL series granulation spray dryer (exclusive to Qiao Feng) is a special dual air liquid granulation nozzle, which is a major innovation in China. It directly converts uniform spherical droplets into particles through uniform heat. Suitable for experimental and small-scale production use, with good particle ball accuracy and uniform particles. Because the device is small in size, it can be installed in a regular laboratory. The core accessories are all imported equipment, and other accessories are produced by well-known domestic manufacturers to ensure the stability and safety of the product. 2. Product features:

1. Atomizing head, Qiao Feng dual gas liquid delivery granulation nozzle
2. Atomization method: From bottom to top, increase the time for droplets to stay in the air
3. The particle size range is 5 microns to 250 microns, and the granulation particle size can be adjusted
4. The airflow regulation of the inner and outer rings can achieve satisfactory particle size requirements.
5. The tower cap design effectively intercepts target particles.
