The Rotary Vacuum Dryer is a highly efficient solvent recovery / drying solution that uses a vacuum to remove moisture / solvent from materials. It is ideal for processing heat-sensitive and highly viscous materials, producing a uniform final product without any product degradation. Our Rotary Vacuum Dryers are available in a range of sizes and configurations to suit various applications and can be customized to meet your specific needs.
The Rotary Vacuum Dryer, also referred to as Rotary Vacuum Paddle Dryer, is an ideal solution for chemical plants seeking efficient wet cake drying and solvent recovery of temperature-sensitive products. At Tech Mech Engineers, we offer a robust and rigid design that maximizes heat transfer and agitation to ensure optimal performance and trouble-free operation.
Our self-cleaning dust collector system improves solvent recovery efficiency and reduces costs by enabling reuse of solvents. We use TME customized Sealing to ensure a high level of vacuum, and the recovered material is suitable for manual handling, bagging, and dispatching. And we offer various unit and drive configurations tailored to your specific requirements, and the operation can be controlled by DCS/PLC to reduce manual intervention.
At Tech-Mech Engineers, we have manufactured Rotary Vacuum Dryers in a range of sizes, from 50 litres to 12 kilolitres, all functioning at optimum efficiency. We understand that every customer has unique requirements, which is why we offer customized solutions to meet your specific needs. Contact us to learn more about how we can tailor the Rotary Vacuum Dryer to your specific requirements.
In addition to Rotary Vacuum Dryers, we also manufacture evaporative systems and heaters of various capacities and sizes.
The Rotary Vacuum Dryer operates under vacuum, which allows for lower operating temperatures and reduces the risk of product degradation. The dryer consists of a horizontally mounted, cylindrical vessel with a rotating paddle shaft running through the length of the cylinder. The paddle shaft is designed with overlapping blades suitable for heating, that sweep the product over the heated surface of the cylinder, providing maximum exposure to the heat transfer surface.
The vacuum system is attached to the dryer, creating a vacuum inside the cylinder, which facilitates the removal of moisture and solvent from the product. As the product rotates in the dryer, the vacuum system draws off the moisture and solvent vapors from the surface of the product. The vapors are then condensed and collected in a condenser, and the solvent is recovered for reuse.
The dryer uses a central rotor to provide agitation and ensure uniform mixing and drying of the product. Any dust formation is arrested within a dust collector system. The solvent vapors are collected, cooled and stored in a receiver, while the dry product powder is discharged through a bottom valve.
By optimizing the heat transfer area, the overall turnaround time of the operation is reduced.
Note: The technical specifications can vary depending on the specific requirements of the customer.
