A rice husker includes a pair of husking rolls. One of the pair of husking rolls is attached to a main shaft and the other of the pair of husking rolls is attached to an auxiliary shaft movable to be close to and away from the main shaft. The rice husker includes abnormality determination means. The abnormality determination means determines that the husking rolls fail to work normally when vibrations having a preset intensity larger than the preset intensity are successively detected by a vibration sensor until a certain time elapses. The certain time is from the start of a husking action to disappearance of distortion on a surface of the husking roll. The vibration sensor is provided on at least either of bearing units of the main shaft and the auxiliary shaft. The vibration sensor detects vibrations occurring due to the husking action by the pair of husking rolls.

A hulling machine configured to perform hulling through a husking roll, a hulled-rice discrimination machine capable of examining hulled rice discharged from the hulling machine, and a hulling control unit capable of controlling the hulling machine in accordance with a result of the examination of the hulled rice at the hulled-rice discrimination machine are provided, and the hulling control unit includes a rotational speed change means configured to change a rotational speed of the husking roll in the hulling machine in accordance with the result of the examination of the hulled rice.

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.

The group of inventions relates to the food industry, namely, to a method and device for processing brewer's spent grains. The invention makes it possible to obtain a gluten-free protein drink with a protein content of at least 10.0 wt. % dry weight. The principle of the invention is based on the technology of preparing brewer's spent grains for the extraction of nutrients and their extraction by mechanical processing on the proposed industrial line. The essence of the method lies in the fact that brewer's spent grains are loosened on a vibrating screen, crushed in a colloid mill, with the addition of water in a ratio of 0.5:1 to 1:1 with respect to the grains, to obtain a paste-like homogeneous mass, and then this mass is processed in a screw extractor for further grinding and separation into 2 fractions, namely: a suspension with a water content of 90-95%, which all nutrients remain in, including the proteins of the brewer's spent grains, and crushed husks of the brewer's spent grains with a water content of 60-75% suitable for further industrial use. Then, the suspension is subjected to removing suspended particles to obtain the final product—vegetable milk (protein drink), which is pumped into a storage tank.
