The Double Cone Vacuum Dryer is a batchwise dryer which handles powder product. As the dryer works in low temperature and high vacuum, it can yield high quality product. It is very suitable for heat-sensitive product.

Double Cone Rotary Vacuum Dryer is suitable for drying of materials which cannot resist high temperature, material which are easily oxidized, volatile materials which should be retrieved, materials which are strong irritants and poisonous in nature.

Double Cone Rotary Vacuum Dryer is completely jacketed, and heat transfer fluid (either hot water or oil, steam or vapor) is circulated throughout the jacket. The unique conical shape assures direct contact between the material and the heated surface so that heat is transferred rapidly by conduction.
As the dryer rotates, the rapid and thorough intermixing of the entire batch brings every particle in contact, time and again, with the heated surface for more rapid heat conduction. This permits high speed drying without raising the drying temperature to the danger-point of the material being processed.
The most important effect of this thorough blending and is maintaining uniform temperature throughout the batch. This prevents re-condensation because there are no cold spots, and it contributes to the speed of drying and elimination of caking.
Finally, a high vacuum is maintained to draw off the moisture under these ideal conditions of material in motion.
Easy to keep clean - the interior of the dryer consists only of the smooth side walls through which the heat is transferred to the product. The thorough mixing and blending action is obtained by the unique shape of the drying compartment. Intersections of cylinders and truncated cones are obtuse angles, so no material is trapped. There are no internal scrapers, ploughs, scoops or vanes to trap and hold material while it cakes or prevents uniform warming and drying. The dryer may be easily cleaned for minimum process delay during change of products or of colors.
