Cereal grain is pretreated before milling, by selectively removing a first fraction of husk components of the cereal, wherein the first fraction includes the outer husk components of the dampened cereal, and wherein 0.2 to 2% by weight of the cereal is removed, then dampening and conditioning the cereal, then selectively removing a second fraction of husk components of the cereal, wherein the second fraction substantially contains dietary fibers of the dampened cereal. The method makes it possible to efficiently obtain contamination-free total dietary fibers. An apparatus for carrying out the method, and advantageous uses of the total dietary fibers are also described.

A system and method for flaking. The system includes a stationary roller, and moveable roller, and an adjustable fixator applying tension between the stationary and moveable rollers. The fixator includes a pressure transducer and a linear indicator. The transducer and indicator allow the fixator to read pressures and make fine adjustments to the fixator to obtain a desired gap between the two rollers.

Methods and systems for producing improved hemp seed products, such as proteins and oils are provided.

An abrading apparatus (1) including a drum (2), a movable abrasive surface (4) about at least part of the circumferential surface of the drum (2) and a plurality of treatment chambers (5) mounted about the drum (2). Each treatment chamber (5) has upstream and downstream faces (53, 54), which describe an open side facing the drum (2), such that the abrasive surface (4) forms a wall of the chamber (5). The downstream face (53) of each chamber (5) is substantially aligned with a radial plane (R) of the drum (2).

A surface-worked granular product is produced by supplying raw granular material to a cylindrical retainer having apertures and retaining sites, floating the granular material by suctioning air from the cylindrical retainer, rotating a rotary working device installed in the cylindrical retainer, and contacting working protrusion protruding from the working device with the granular material to remove foreign substances and to perform surface-working of the granular material so as to form a rough surface without causing degeneration, denaturation or substantial removal of useful ingredients, wherein the surface-worked granular product has surface characteristics different from raw granular material.
