The working principle of the **double cone rotary vacuum dryer** is based on a unique combination of vacuum conditions and mechanical rotation to achieve efficient and uniform drying. The **SZG double-cone rotary vacuum dryer** features a double-conical tank that rotates slowly around its axis. This tank operates under vacuum, which significantly lowers the boiling point of moisture, allowing for gentle and energy-efficient drying. A heating medium such as steam or hot water circulates through the jacket surrounding the tank, transferring heat to the inner walls. As the wet material comes into contact with these heated surfaces, it absorbs the thermal energy, causing the moisture to evaporate.
The evaporated moisture is then removed from the system via a vacuum pump through an exhaust pipe, ensuring a continuous and controlled drying process. The rotating motion of the tank causes the material to tumble and mix constantly, promoting even heat distribution and preventing localized overheating. This tumbling action also enhances the drying rate by exposing all parts of the material to the heat source and vacuum environment. As a result, the **double cone rotary vacuum dryer** not only speeds up the drying process but also ensures consistent quality and uniformity in the final product.
This type of dryer is widely used in various industries, including pharmaceuticals, food processing, and chemical manufacturing. It is particularly suitable for handling powders, granules, and other particulate materials that require careful drying conditions. The **double-cone rotary vacuum dryer** is ideal for materials that are sensitive to heat, prone to oxidation, or contain volatile solvents and toxic gases. It is also well-suited for applications where solvent recovery is necessary, or where maintaining a specific crystal structure is crucial. Additionally, it can be used for mixing and drying in a single unit, making it a versatile and efficient choice for many industrial processes.
