Container for multi-phase processing

A system for processing solid material with a liquid, the system comprising:

• a tank;
• a container for holding solid material that is to be processed with the liquid, the container comprising a generally cylindrical body rotatable about a longitudinal axis;
• a plurality of slots formed in the body, each slot extending generally in a circumferential direction with respect to the longitudinal axis, each slot having a leading edge and a trailing edge;
• each slot having a component of its shape substantially aligned with the circumferential direction;
• the leading edge being tapered toward the trailing edge, the leading edge being configured to direct the liquid to the trailing edge;
• and
• the trailing edge being configured to direct the liquid from an exterior of the body to an interior of the body through the respective slot,
• wherein each slot is curved with respect to an axial direction of the cylindrical portion when the respective slot is viewed in a radial direction.

A container for holding solid material that is to be processed with a liquid, the container comprising:

• a cylindrical portion having a cylindrical wall, the cylindrical wall having an outer surface and an inner surface;
• a plurality of circumferentially spaced apart slots defined in the cylindrical wall and extending from the outer surface of the cylindrical wall to the inner surface of the cylindrical wall;
• and
• each slot of the plurality of circumferentially spaced apart slots being defined by a first edge portion forming a first edge of the slot and a second edge portion forming a second edge of the slot,
• the first edge portion extending at a first angle with respect to a first radial line from a center of the cylindrical portion to an outer edge of the first edge portion, and the second edge portion extending at a second angle with respect to a second radial line from the center of the cylindrical portion to an outer edge of the second edge portion, the first angle being greater than the second angle.
