With a smooth internal finish, complete discharge and elimination of cross batch contamination are realized. Our cone tumble dryers can be designed for up to 500º F jacket temperatures and high vacuum. For superior drying, mixing and ease of cleaning the Orbis Machinery cone tumble dryer is the dryer of choice.
Tumble drying of materials is accomplished by heating the walls of a jacketed, slow rotating double cone shaped vessel while applying vacuum. By applying vacuum, the boiling point of the liquid component(s) is lowered, while constant particle contact with the vessel walls provides uniform drying action. Revolving dryers rotate at low speeds (3 to 12 RPM, depending on the capacity of the dryer).
The heating jackets can be supplied for operation at 100° to 500° F. As a standard, all our hot oil or steam jackets include high temperature insulation covered by a watertight insulation shroud. Heating of the jacket is commonly accomplished using hot oil, but other heating sources such as steam or electric blankets, may also be used. Using oil as the heating medium, allows for faster cooling of the product after the material has been dried, for faster and safer unloading and handling.
Two cones are welded to a cylindrical center section providing a gentle, low shear, tumble action of the product. Our cone tumble dryer design results in a high degree of particle mobility without the use of internal baffles (45° and 60° cones are available). Cone tumble dryers have been proven in a wide variety of industries, offering greater overall volume and high efficiency.
