Abstract: Machine for milling cereals, in particular rice, in an annular space (11) which has a vertical axis and is bounded on the outside by an outer casing (4), containing through-passages, and on the inside by a rotor (8), coaxial with respect to the same, and to which the milling material is fed by means of a positively driven conveyor (21). In order to increase the machine capacity along with the material being treated more gently, the outer casing (4) and the rotor (8) are frustoconical, the material is fed at the top, narrower end of the annular space (11), and the bottom end of the latter is provided with a compliant closure element (32).

Abstract: A husking machine for cereals, with a husking roller mounted in fixed bearings and with a husking roller which is adjustable along an approximately horizontal path and the bearings of which are arranged on a support displaceable on guide members. The support is equipped with linear horizontal guide members, so that the geometric relationships of the roller gap always remain constant. The husking rollers are driven via belt pulleys arranged on their shafts. In the region of the adjustable husking roller, the belt drive is guided in the form of a Z over a fixed belt pulley, then, parallel to the direction of the guide members, to one of the two belt pulleys arranged on the support, from this to the other belt pulley arranged on the support, and finally, parallel to the direction of the guide members, to a belt pulley arranged fixedly. As a result, the belt tension becomes independent of the readjustment of the husking rollers.

Abstract: Machine for peeling cereal grains, especially rice, by means of rubber rolls. Above the rolls (1,3) there is a bin (7) for the supply of material. An arrangement (13-18) is present, which cuts off the supply of material and/or separates the rubber peeling rolls, when a minimum loading (10) in the bin has been passed in the downward direction. The bin is mounted on springs (9) so as to be movable up and down, so that its position in the vertical direction is dependent on the degree of loading. The bin cooperates with a control (15) which is arranged fixed on the frame and which is changed over when the container reaches a high level because of its minimum loading, for separating the rolls (1,3) or for turning off the material supply. The control is again changed over when the bin has moved downwards again because of attaining a higher loading (11).

Abstract: The invention relates to a rice polishing machine including a housing with a shaft which is mounted essentially horizontally therein and which carries a drive coupling member on one end thereof and a polishing rotor with a polishing surface on the opposite end thereof, and also carries a conveyor screw connected coaxially and fixedly to the polishing rotor. The housing is provided with a rice feed orifice at the conveyor screw, and with a rice discharge orifice at the end remote from the conveyor screw. In addition, a screen housing is provided, surrounding the rotor at a short distance therefrom, and a funnel member is provided underneath the screen housing for collecting and discharging the polishing powder. The present invention contemplates an uncomplicated and easily understandable construction which can easily be dismantled and is easily maintained.
