Rotary Vacuum Paddle Dryer. Also known as the RVPD, is an efficient batch drying systems where wet cakes can be dried at lower temperatures under high vacuum. The use to vacuum, lowers the boiling point of the solvents to be extracted and the indirect heat imparted to the wet cake results in flashing of the solvents into vapours.

Each material responds uniquely to drying. In general, however, those with a moisture content higher than 30% can be problematic, leading to sticking issues on the dryer's interior. Rotary dryers are still an option when this occurs, but some level of preconditioning may be required to bring the moisture content into a more suitable …

A mathematical model able to predict solid and drying gas temperature and moisture content axial profiles along a direct contact rotary dryer was developed. The study was focused on the drying ...

Rotary dryers consist of a large, rotating drum through which wet solids are passed. As the material moves through the dryer, heat and air are used to remove the desired amount of moisture, with the mode of heating dependent on whether the unit is of the direct or indirect configuration. Most dryers are of the direct design, in which the ...

Rotary dryers are known as the workhorse of industrial dryers. They are able to process a wide variety of materials, and can lend a hand in nearly any industry requiring industrial drying solutions. Some of the most common industries and materials in which FEECO rotary dryers are employed include: Aggregates. Agricultural By-Products.

DESCRIPTION: Chemiplant Rotary Vacuum Paddle Dryers are used to attain dry powders from wet cake or solutions. Mostly these dryers are operated under Vacuum & are a batch operation.
