The difference in the working mode of the finned tube according to the characteristics of the material

   The principle of work in dry environment for the hot air heating material, water will be in circulation along with it, in the drying process, because of the higher temperature has been close to the saturated state, so if the finned tube at high temperature and high humidity environment air has been unable to lose water, so when the water began to stop will be volatile, if you still continue to influence various unfavorable work will be, will work to optimize this approach.


If you use it, the material of the water more, one of the consequences is in a short period of the hot air outside into the saturated state, at this time will be a new wind drying process, after means in finned tube heat, the hot air temperature in the dryer in the same time, will be excluded from the opposite side of the port in the oven in the tunnel, contrary to the hot air flow and material flow.


There is also a case of hot air circulation drying, because the material moisture content is not high, so it is not easy to in a relatively short period of time of the hot air causes saturation, but if you need to keep dry condition and evaporation temperature, certain at this time, by removing part of hot air, add fresh air, energy saving consumption, reduce production costs. The supplement of the new wind is generally 20-30%, which depends on the requirements of the process.
