この考案は循環式精米機の改良に関するもので
ある。[Detailed description of the invention] This invention relates to an improvement of a circulating rice mill.
循環式精米機の垂直循環回路には、突起抵抗装
置を設け、該垂直循環回路の内圧を変化せしめて
いる。 A protruding resistance device is provided in the vertical circulation circuit of the circulating rice mill to change the internal pressure of the vertical circulation circuit.
従来の突起抵抗装置１は、第４図に示すよう
に、垂直循環回路２のＲ状外壁３側に設けられて
いる。そして、ハンドル４を回転させてねじ５を
回動させることにより突起抵抗体６を垂直循環回
路２内に出し入れしている。 The conventional protrusion resistance device 1 is provided on the R-shaped outer wall 3 side of the vertical circulation circuit 2, as shown in FIG. By rotating the handle 4 and rotating the screw 5, the protruding resistor 6 is moved in and out of the vertical circulation circuit 2.
しかし、この装置１はハンドル４の部分が前記
回路２の外壁３から外側に長さｌだけ突出してい

に触れてハンドル４が不用意に回転し、精白度に
むらを生じる恐れがある。 However, in this device 1, the handle 4 protrudes outward by a length l from the outer wall 3 of the circuit 2, so when the operator lifts the brown rice in the container and puts it into the circulation tank, or When putting the white rice discharged from the white rice outlet into a container and carrying it out, a part of the worker's body is likely to come into contact with the protruding part of the handle 4, which is dangerous. This may cause uneven polishing.

低下するために内壁寄りの部分を上昇する玄米の
流速v12aとの速度差δvが低下して、この間で行わ

て精白能力をそれ程増加できない。 When the vertical circulation circuit 2 in which the outer wall surface 3 is formed in an arc shape and the milling room side wall surface is formed in a vertical shape is connected to the outlet of the milling room, brown rice from the outer wall surface is removed due to the nature of the shape of that part. Normally, the rising speed v 12 b is greater than the speed v 12 a from the side wall of the milling room, but if the resistor 6 protrudes from the outer wall 3 side in the vertical circulation circuit, the unpolished rice in this area Even though the pressure between them increases, the velocity difference δv between the flow velocity v 12 a of brown rice rising on the part closer to the inner wall decreases because the flow velocity v 12 b of brown rice rising on the outer wall part decreases, and during this period The whitening effect due to the friction being carried out is reduced, and the whitening ability as a whole cannot be increased that much.
