basic information
This is an introduction to the "Vacuum Mixing Dryer" with a jacketed cylindrical or groove shape (U-shaped) and equipped with a single-axis agitator such as ribbon blades or paddle blades. 【Features】 - Since drying occurs under vacuum, it is possible to maintain a large temperature difference between the heat transfer surface and the material being processed. - The processed material comes into direct contact with the heat transfer surface while being mixed and crushed, resulting in high efficiency and uniform drying products. - By selecting the type of shaft seal, high vacuum (low temperature) operation is possible, making it ideal for drying materials that are prone to air oxidation and high-temperature degradation. - It can also be used for evaporated vapors that are harmful or for solvents. - Compared to hot air drying methods, there is less powder scattering. - Hot water, steam, or thermal oil can be used as heat sources. - When handling materials that are prone to sticking and forming dough-like or lump-like shapes, adding balls or round bars can promote drying speed and reduce rotational resistance. *For other functions and details, please download the catalog or contact us.
