SZG series double-cone rotary vacuum dryer is a double-cone rotary tank. In the vacuum state, steam or hot water is heated into the jacket, and the heat is in contact with the wet material through the inner wall of the tank. The vapor evaporates after the wet material absorbs heat and is pumped away through the vacuum pump through the vacuum exhaust pipe. Because the tank is in a vacuum state, and the rotation of the tank makes the material constantly up and down, inside and outside, it speeds up the drying speed of the material, improves the drying efficiency, and achieves the purpose of uniform drying.
