A horizontal rotating drum for mixing and drying treated seed with multiple functional zones separated by one or more dams that are attached to and rotate with the drum. The dam regulates the flow of seed through the drum's functional zones. The dam has one or more cleanout passages and an overflow passage centrally disposed within the dam to selectively regulate seed flow.

This invention relates to a rotary dryer with multi-drying chambers which is developed and improved for drying materials such as cassava chip, paddy, corn, various crops, longan, fertilizer, biomass and mining industry with better drying efficiency. The rotary dryer with multi-drying chambers according to this invention comprises a base frame, a drive assembly installed on the base frame, in which the drive assembly comprises a motor and a plurality of rollers, a drying chamber assembly having a moist material inlet part at one end and a dried material outlet part at the other end, in which the moist material inlet part and the dried material outlet part are installed on the rollers of the drive assembly, a moist material inlet assembly capped to the moist material inlet part and installed on the base frame, a dried material outlet assembly capped to the dried material outlet part and installed on the base frame and a housing encompassed the drying chamber assembly and installed on the base frame, characterized in that the drying chamber assembly comprises a plurality of drying chambers formed from an axial core, a plurality of drying chamber partition walls installed around the axial core and a plurality of drying chamber enclosure walls fixed to the plurality of drying chamber partition walls, in which a plurality of material flow control assemblies is provided in each of the plurality of drying chambers.

Provided is an indirectly heating rotary dryer which has achieved enhanced energy-saving performance by reducing heating tubes non-contacting with material to be dried and reducing power required for rotation even when a hold up ratio is increased. Specifically provided is an indirectly heating rotary dryer having four partition walls 16 extended respectively along an shaft center C in an inner space of a rotating shell 10 at angle intervals of 90 degrees in the vertical and horizontal directions. The four partition walls 16 partition the inner space of the rotating shell 10 at a lateral section of the rotating shell 10 into four approximately-sector-shaped small spaces K respectively extended along the shaft center C. Heating tubes 11 are aligned in the rotating shell 10 in three lines extended respectively in parallel to the shaft center C of the rotating shell 10. The heat tubes 11 heat and dry the material H to be dried by supplying heated steam to the heating tubes 11 and performing heat exchange with the material H to be dried in the rotating shell 10.

A drying device for a mixture of a liquid and one or more solids, having a receiving container for the mixture, a rotor that is situated with one section of its circumference in the receiving container, and a drive device for rotatively driving the rotor, the rotor having a plurality of flat entrainment elements, characterized in that the entrainment elements have a radial orientation with respect to a rotational axis of the rotor, wherein at least some of the entrainment elements have a configuration in which relatively narrow entrainment elements alternate with relatively wide entrainment elements in the circumferential direction of the rotor, and/or at least some of the entrainment elements are provided with a plurality of through openings.

A multi-functional slurry processing system (VARCOR) and associated methods is disclosed. The present examples provide a multi-functional slurry processing system incorporating systems and methods for separating liquid and solid components in slurries. In particular the systems and methods described herein produce clean water, dried solids, and potential concentration of desirable constituents with a boiling point lower than water. At least one example of the multi-functional slurry processing system provides a self-contained processing facility configured to efficiently convert high water-content slurries into its constituent solid and liquid fractions and subsequently generating and collecting clean water and concentrating desirable constituents with a boiling point lower than water. The multi-functional slurry processing system advantageously applies thermodynamic principles in a system which may include various combinations of a preheater, a degassing unit, a dryer, a steam filter, a compressor, a concentrating tower, and a condensation unit.

The invention relates to a tubular reactor with a rotating reactor chamber (9) for thermal treatment of biomass. It is characterized by the reactor chamber (9) being subdivided into zones by ring-shaped plates (10). These zones cause the particles to be retained in a particular area and thoroughly mixed there, i.e., the particles being treated are homogenized and the retention time also becomes more homogenous.
