1. Rotation speed of double cone rotary vacuum dryer In general, the rotation speed of the cylinder of a double cone rotary vacuum dryer is proportional to the drying speed. But in the late drying period, with the decrease of the wet content of the material, the drying speed is also reduced, at this time the speed increase is unprofitable.
In addition, in the early stage of drying, the faster rotation speed, easy to cause wet vaporization too fast and material bonding into a group phenomenon.
2. Heating and cooling of double cone rotary vacuum dryer Double cone rotary vacuum dryer jacket Domestic demand convection heat transfer and provide heat and cold quantity respectively, so the jacket will have the experience of two days of water and fire.
