概述 Descriptions
濕物料從干燥機(jī)一端投入后,在內(nèi)筒均布的抄板器翻動(dòng)下，物料在干燥器內(nèi)均勻分布與分散，并與并流(逆流)的熱空氣充分接觸，加快了干燥傳熱，傳至推動(dòng)力。在干燥過(guò)程中，物料在帶有傾斜度的抄板和熱氣流的作用下，可調(diào)控地運(yùn)動(dòng)至干燥機(jī)另段星形卸料閥排出成品。
After wet materials are put in from one end of the dryer, the materials are evenly distributed and dispersed in the dryer under the turning of the paper-making machines evenly distributed in the inner cylinder, and are fully contacted with the hot air flowing in parallel (countercurrent), thus accelerating the drying heat transfer and transmitting to the driving force. In the drying process, the material can move to the other star-shaped discharge valve of the dryer to discharge the finished product under the action of the inclined papermaking plate and hot air flow.
