(Cl. 83-29) This invention relates to a method of remov- -machine through which thgrain is passed is ing in a continuous operation the husk from cethe magnetic separator and sorter R. From the real grains of all kinds, which is valueless for latter the grain passes first into a washing and the digestion. There have been a great number wetting machine I of suitableconstruction where I of attempts to realize this object. it is treated in a drum revolving in water, where g Apart from the known husking, brushing and it remains sufilciently long for the husks of the scrubbing processes it has been proposedto move grain to become loosened and softened. Thethe cereal grains in the moistened state relagrain is at the same time washed during this optively to one another under the application of eration, the adhering dirt, sand, dust and the in pressure and heat, "with the object, when the like being loosened from the grainand washed grains strike against resistances or striking surway. In this machine the husks are $19111 left faces, of loosening the husk on the cereal grains adhering to the grains. The duration of the or of removing it from th treatment and the suitable temperature of the According to the invention the husk is 1005- washing water ar a ain d y xp n ened far more effectively by causing the moisand depend to a certain extent on the place of 7 tened cereal grains to rub against one another origin and quality of the grain.

For causing the grains which rub against one another under the action of gravity'to travel through the drum 0 a shaft d is mounted in the latter, which is provided with rake-like stirring arms I and h. On these arms a brush or stripper i is mounted. the function of which is gently to detach the grains adhering to the wall of the casing a'and ior the rest to convey the grains on the bottom plate 8 of the drum 0 to the outflow c. The stirring device which is driven by bevel wheels e or the like rotates quite slowly. It is of importance that the stirring device shall have no sharp corners and angles, so asto avoid any mechanical damage to the grainsby the stirring device.
