1, the food in the drying process, where contact with the product of the area, sterilization must be easy to clean;
2, should take measures to prevent coke powder, to prevent hot air vortex with countercurrent, meet the technical requirements;
3. The increase in impurities in the product should pay particular attention to ensure that hot air clean. Since the efficiency of the air filter
If the bad, the wind pipe and heater center of rust and leaks in insulation materials caused;
4, in order to facilitate the inspection of production operation, you should configure the temperature, pressure indicator recorder, light hole
And so on;
5, having a high recovery of dust recovery;
6, in order to increase the solubility of the product, instant sex, the dried product should be quickly removed from the drying chamber
Cooling (continuous flour);
7, drying chamber temperature and exhaust air temperature must not exceed 100 ℃, it is not only to ensure the quality,
And security issues (because the powder gas concentration reaches a certain value, the temperature is higher than 160 ℃, In case of a flash fire, explosion);
8, to improve the thermal efficiency of the drying chamber, when the concentration of the material must be in uniform contact with the spray droplets and hot air,
Secondly, heaters, drying room, air duct should be insulated. 9, for viscous materials should minimize the sticky wall phenomenon.
