Common pre-drying machines in China have common spray dryers, air dryers, fluidized bed dryer flash dryers, fluidized bed dryers, such as spray granulators. Flash Dryer Spray Drying Spray drying is one of the most advanced equipment in drying equipment. Three kinds of atomization of traditional methods: rotary atomization, pressure atomization and gas atomization. Rotary atomizing characteristics A large spray drying capacity (up to 200 tons/hour) will be responsible for the ease of control, operational flexibility, and wider application. Pressure atomized spray drying is characterized by coarse particles that can be created for future maintenance. Since the nozzle hole is small, it is easy to clog and the liquid must be strictly filtered. The nozzle hole is easy to wear and the use of wear-resistant materials. There is also a new structure of nozzle pressure called pressure-flow nozzles. It is characterized by nozzle pressure, ambient air gap nozzles. The atomization is divided into two stages: the first to form the liquid film pressure nozzle, and the film is the second air atomization, thereby making more small droplets. The advantages of this type of nozzle: (1) Adjust the pressure of the compressed air, can adjust the diameter of the droplet, and the operation is simple; (2) Produce a highly viscous liquid, which can atomize the droplet fine; 3 If you disable compression Air, original pressure nozzles can be used. The atomized air flow of the laboratory and its main plant in the Middle East consumes electricity from it. The first two liquids that cannot atomize the nozzle use air-atomizable nozzles. High-viscosity paste, paste and filter cake materials can be used for atomization of three-fluid nozzles. Dryer air drying technology matures if the operating data can be designed directly.
At present, there are a large number of dryer equipment manufacturers that can provide this type of equipment.
Fluidized Bed Dryer Fluidized Bed Dryer Spray Dryer. The feeding setup was divided into a partial fluidized bed dryer stirrer and a heat transfer fluidized bed dryer. When the unity is easy to use for the fluidized bed drying, or more water gathered by the feed of the powdered material will flow into the above-mentioned difficult phenomenon, this time the feed mixer is set up to eliminate the bunching problem to achieve normal flow. The latter is a combination of heat transfer and convection heat transfer, when the normal flow of hot air used is far from sufficient in the country to meet the required heat drying set using the heat exchanger, which supplies part or most of the heat, which types of Operation can greatly save energy. Take various forms of heat exchangers. Fluidized bed drying is also often used in combination with dry secondary education and higher education. The implementation of ordinary vibration fluidized bed said that the vibration fluidized bed. A vibrating vibration source can be divided into two types: one is driven by a vibration motor, and the other is an ordinary motor that generates vibration through a vibrating box to make a spring. When vibrating, the bed size is better. In the process of fluidized bed spray granulator dryer, fluidization technology, atomization technology and dry organic combination are three. It is the seed that will atomize the spray liquid into the fluidized bed, so the seed continues to grow and dry to reach the desired size, time out of the catapult. The device's small and large production capacity can create large particles. The industrial application of this device has been increasing.
