1. Introduction of laboratory centrifugal spray granulation dryer:
The laboratory centrifugal spray granulation drying unit is a multi-purpose unit based on domestic and foreign advanced technology and developed through many experiments. It is widely used in the spray granulation drying process of chemical, light industry, food, laboratory research and other industries. The unit has the advantages of short heating time, high thermal efficiency, and complete dust removal system.
The core device of the unit is a granulation atomizer. In this way, the liquid is atomized into micron-sized droplets and then quickly dried by hot air, the dried particles are recovered through the bottom receiving bottle, and the powder is recovered through the cyclone separator. The maximum designed air inlet temperature is 250°C, and the outlet air temperature is about 145°C.
The material of the drying tower body and accessories is selected by the customer. The heat source required for drying hot air, the electric heating power is about 25KW. The arrangement of equipment can be arranged according to the actual needs of users.
The centrifugal spray granulation dryer is a set of small, small batch production medium and mass production granulation spray dryer independently developed by Shanghai Qiaofeng. QFN-ZL series granulation spray dryer (manufactured by Qiao Feng) has a special dual gas liquid feeding granulation nozzle, a major domestic innovation, which directly transforms uniform spherical droplets into particles through uniform heat. It can be used in experiments and small-scale production, with good particle ball precision and uniform particles. Because the device is small, it can be installed in an ordinary laboratory. The core accessories are all imported equipment, and other accessories are produced by well-known domestic manufacturers to ensure product stability and safety.
2. Features of laboratory centrifugal spray granulation dryer:
Atomizing head, Qiao Feng dual gas liquid feeding nozzle
Atomization method: from bottom to top, increase the time that the droplets stay in the air
The particle size ranges from 5 microns to 250 microns, and the granulation size is adjustable
The airflow adjustment of the inner ring and outer ring can achieve satisfactory particle size requirements.
The cap design inside the tower can more effectively intercept the target particles.
3. Laboratory centrifugal spray granulation dryer structure:
The high-speed centrifugal spray granulation dryer is composed of primary air filter, blower, high-efficiency air filter, steam heater, electric heater, air distributor, nozzle (high-speed centrifugal atomizer), drying tower, air hammer, cyclone It is composed of separator, induced draft fan, dust collector and other components.
