[0004]

Therefore, according to the present invention, a tapered conical surface 32 whose upper end is substantially the same as the inner diameter of the polishing cylinder 6 and which becomes larger toward the upper part is provided at the upper part of the vertical polishing cylinder 6. A resistance metal fitting 33 is fixed, and an upper end 15 of the vertical rotation shaft 1 provided at the center of the whitening cylinder 6 is provided so as to protrude above the resistance metal fitting 33. 34 is inserted so as to be slidable up and down slidably and resiliently down a fixed width, and the outer periphery of the lower edge of the resistor 34 is a corner 38 having a substantially right-angle cross section, and the corner 38 is formed of the conical surface 32. This is a load adjusting device for an ascending rice mill having an abutment portion 36 formed so as to abut the entire circumference at an intermediate position in the width direction.

Next, the operation will be described. When brown rice is supplied into the supply hopper 18 and supplied from the lower end opening 19 to the supply port 7 via the insertion hopper 9, the inside of the grain feeding cylinder 5 is raised by the upward feeding grain feeding spiral 3, and Is stirred by the whitening roll 4, but in the present application, the upper end of the whitening cylinder 6 has a tapered conical surface 32 whose lower end is substantially the same as the inner diameter of the whitening cylinder 6, but whose inner diameter increases toward the top.

According to the above-mentioned known apparatus, since the outlet is formed on the side, a biased pressure is given to the refining chamber,
There was a problem that whiteness adjustment could not be performed smoothly. However, according to the present invention, a resistance metal fitting 33 having a tapered conical surface 32 whose lower end is substantially the same as the inner diameter of the fine polishing cylinder 6 and becomes larger toward the upper part is fixed to the upper part of the vertical polishing cylinder 6, The upper end 15 of the vertical rotation shaft 1 provided at the center of the cylinder 6 is provided so as to protrude above the resistance fitting 33, and the upper end 1 of the vertical rotation shaft 1 is provided.

Is a load adjusting device of a lift-type rice milling device provided with a contact portion 36 formed so as to abut on the entire circumference at an intermediate position of the conical surface 32 in the width direction. When the polished rice moves upward on the tapered conical surface 32 whose inner diameter increases toward the upper part, the resistance is given by the resistor 34 inserted through the vertical rotation shaft 1, so that the resistance is given without unevenness around the entire circumference. The effect is that rice is reliably and evenly polished.
It is to be noted that the cross-sectional shape of the outer periphery of the lower edge of the resistor 34 is a substantially right-angled corner 3
When the diameter of 8 is larger than the conical surface 32 as shown in FIG. 3, the grain is sandwiched between the corner 38 and the conical surface 32, and the resistor 34 is not completely tightened.
