Drying Principles
SZG series double cone rotary dryer: The body is a double cone rotary tank, and the inner liner is made of. The jacket is filled with steam or hot water, which heats the inner liner and conducts heat to the material through the inner liner wall, vaporizing the water in the material. The water vapor is continuously extracted through the steam extraction pipe, and the tank is in a vacuum state, accelerating the drying speed of the material. The tank rotates at low speed, with materials constantly turning inside and outside, up and down, replacing the heating surface, and ultimately achieving uniform drying.
Rotation Speed
However the faster the rotation speed of the double cone rotary vacuum dryer cylinder, the higher the drying speed,. However, in the early stage of drying, if the rotation speed is fast, it is easy for the material to bond and form clusters. Therefore, in the early stage of drying, a lower rotation speed is used to increase the rotation speed of the cylinder when the material surface is relatively dry. In the later stage of drying, as the moisture content of the material decreases, the rotation speed should also be appropriately reduced. At this time, increasing the rotation speed is not beneficial for improving the drying speed. Therefore, during the drying process, workers should adjust and control the material according to its condition at any time. In short, the rotational speed is not fixed and should be adjusted promptly according to the actual situation.
