摘要： An apparatus and method for providing a simpler and more robust mechanism for transporting materials to be dried through a vacuum microwave chamber in rotating containers. The apparatus (20) has a vacuum chamber (22), an input end (26) to introduce a container (24) into the chamber, and a discharge end (28) to remove the container. The container has spur gear teeth (60) extending along its outer circumferential surface. The apparatus has a single roller (42) having spur gear teeth (46) extending along its outer circumferential surface. The spur gear teeth of the roller mesh with the spur gear teeth of the container such that rotation of the roller about its longitudinal axis rotates the container. The apparatus also includes means for holding the container on the roller, means for moving the container through the chamber, a microwave generator 76 arranged for transmission of microwave radiation from the generator into the chamber, and means for reducing pressure inside the chamber.

摘要： The dryer comprises a dryer receptacle having an inner space for receiving herbaceous material and a driving device for rotating the dryer receptacle about a rotation axis of the dryer receptacle. Vanes for engaging herbaceous material received in the inner space of the dryer receptacle extend from an inner surface of the dryer receptacle into the inner space of the dryer receptacle. In a cross-section with a sectional plane perpendicular to the rotation axis, the vanes are inclined with respect to the radial direction. Vane heating elements are incorporated into the vanes.

摘要： A tumbler may be used as defluidizer, dryer, coater, classifier, or dynamic filter. The tumbler includes a rotatable drum that receives a solid/fluid slurry through an inlet chute. As the slurry travels through the drum, fluid exits the drum through a plurality of apertures in screens attached to the sides of the drum, while the solids continue along the drum's length until they reach one or more openings and exit the drum into an outlet chute. The outlet chute includes ridges that wrap around rings extending from the openings of the drum to prevent solids from escaping the outlet chute. To further dry the solids before they exit the drum, an air tube at least partially disposed within the drum is configured to introduce a flow of air into the drum.

摘要： A seed drying system for positioning a manifold in a seed treater includes a seed treater that contains a plurality of seeds that have been coated with a liquid treatment. A manifold is positioned within the seed treater and a fan is provided to selectively urge air. The fan is fluidly coupled to the manifold to direct the air over the seeds thereby facilitating the liquid treatment to dry on the seeds. A mounting unit is provided and the manifold is coupled to the mounting unit such that the mounting unit retains the manifold in a horizontal orientation. The mounting unit is releasably coupled to the housing such that the manifold is retained in the drum. Moreover, the mounting unit centrally positions the manifold in the aperture.
