​Drying equipment common sense
- Feb 13, 2017 -

Drying equipment common sense: common pre-drying machine in China are common spray dryer, air dryer, fluidized bed dryer flash dryer, fluidized bed dryer spray granulation. Flash dryer spray drying spray drying is the drying equipment of one of the most advanced equipment. Traditional methods of three kinds of atomized: rotary atomizer, pressure atomization and air spray. Rotary atomization characteristics of spray-drying capacity of a large (spray volume up to 200 t/h), would be responsible for will be easier to control, operational flexibility, as well as more widely. Pressure atomizer spray drying is characterized by coarse particles can be created, so that future maintenance. As the nozzle hole is very small, very easy to plug, must be strictly filtered liquid. The nozzle hole easy wear, wear-resistant materials used. There is a nozzle pressure of the new structure, called the pressure-flow nozzle. It is characterized by the nozzle pressure, ambient air gap nozzle. Atomization is divided into two stages: first the formation fluid pressure nozzle, the film was the second air atomization, thereby increasing the number of water droplets. The advantages of this type of nozzle:
(1) adjust the pressure of the compressed air, you can adjust the droplet diameter, easy operation;
(2) production, high viscosity liquid, it can be atomized droplet fine; 3 If you disable the compressed air, the original pressure nozzle can be used. Laboratories and in the middle of the main plant of atomized air, its power consumption. First two not atomizing nozzle the liquid, use air atomizing nozzles. High viscosity paste, paste and material of filter cake can be used for c fluid nozzle atomization. Drier air flow drying technology is mature, if the operation of the data will be designed. At present, there are many drying equipment manufacturers are able to provide this type of equipment. Fluidized bed dryer fluidized bed dryer spray dryer. Feeding set is divided into part of the fluidized bed dryer mixers and heat flow fluidized bed dryer. When unity is the easy to use fluidized bed drying, powder feed or gather difficult even more water will flow to the same phenomena, fodder mixer set up at this time above, the eradication of cluster issues, in order to achieve normal flow. The latter is a combination of conduction and convection heat transfer, when using the normal flow of hot air is far from enough countries to meet the required thermal drying of heat exchanger using the settings, some or most of the heat supply, what kinds of operations can result in significant energy savings. Heat exchanger take many forms. Fluidized bed drying is often used for drying of secondary education and higher education. Introduction of normal vibration fluidized bed said vibration fluidized bed. A mobile vibration vibration source can be divided into two classes: one for motor-driven, the other for normal motor vibration generated by the vibration box, spring. Vibration, bed size, the latter better. Process of fluidized-bed spray granulation drying machine in the Fluidization technologies, atomization and dry combination of the three. It is by spraying the atomized liquid enters the fluidized bed of seeds, so continued growth and dried seed, to reach the desired size, time catapults. The device small and large capacity, can create large particles. The industrial application of equipment has increased.
