I. Pigment Carbon Black Dryer--Overview of Equipment

Vacuum  dryer is a novel horizontal intermittent vacuum drying equipment with simple structure, convenient operation, long service life, stable and reliable performance, low energy consumption and strong applicable performance. It is especially suitable for high temperature resistance. A flammable, oxidizable paste material, and a material that must be recovered from steam or solvent that is removed during the drying process. Vacuum kneading dryers are widely used in the drying of semi-finished powder wet slag in the chemical, feed and food industries.

The drying cylinder of the vacuum sputum dryer device is provided with a jacket for indirect heating of the material by steam or heating oil, and the wet material is added by the feeding port and stirred under the rotation of the continuously rotating dent or ribbon, when the material is in contact with the casing wall, the surface Constantly updated, the dried material is indirectly heated, so that the moisture in the material is continuously vaporized, and the vaporized water vapor is pumped away by the vacuum pump in time. Due to the high degree of vacuum operation, it is beneficial to lower the vaporization temperature of the water and is dried. The water vapor pressure on the surface of the material is much larger than the water vapor pressure in the evaporation space in the dryer casing, which is beneficial to the discharge of internal moisture and surface moisture of the dried material, which is beneficial to the movement of water molecules of the dried material, thereby improving the efficiency and speeding up the drying speed. .
