Roto Cone Vacuum Dryer is suitable for drying the material which can not operate at low Temperature easily oxidized, poisonous in nature. It operates at low Temperature efficiently under vacuum. It is very economical by total solvent recovery.
The roto cone vacuum dryer is equipment used in drying of products that are damaged by high temperatures and materials having special characteristics such as easily oxidized, strong irritants, poisonous dust and volatile compounds. The machine is also designed to release a product that is completely powdered and lump free.
In operation, the rotocone vacuum dryer dries product through creation of a vacuum. This decreases the pressure around the product to below the vapor pressure of water and creates the effect of reducing product water boiling point which then evaporates and there is enhanced rate of drying of the product. The process is also done under low relative humidity for better drying.
To enhance the rate of drying, the rotocone vacuum dryer manufacturers may add lump breakers onto the cone for breaking the large clumps of material inside the rotating cone, increasing the drying surface area and achieves more efficient drying.
Double Cone Vacuum Dryer
The double cone vacuum dryer also utilizes the vacuum drying technology with greater drying efficiency. Wet product goes through an indirect heating process and agitation with tumbling action, all while inside a vacuum to achieve rapid drying. In this process, recovery of solvent is also possible through condensation processes. With constant innovation, the RVCD manufacturer has been able to deliver highly precise models that achieve thorough drying of product, uniformity of products, reduced drying time and an easy to clean and maintain machine. The roto cone vacuum dryer is mainly used in chemicals processing and pharmaceutical industries where air contamination can easily occur with other types of dryers.
