Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a residual rice discharge device in an ascending vertical rice mill.

(Prior art) The specification and drawings of Japanese Patent Application No. 61-29366 (see Japanese Unexamined Patent Application Publication No. 62-201655), which is an earlier application to the present application, show a vertical rotation shaft provided in a box-shaped case and a An upward feeding grain spiral provided at a lower position of the shaft, a milling roll provided at an upper position of the vertical rotation shaft, and a lower end surrounding the outer periphery of the upward feeding grain spiral as an inverted conical saucer bottom. a grain cylinder, a polishing cylinder surrounding the outer periphery of the polishing roll, and a supply hopper provided on the side of the grain feeding cylinder, the bottom of which is lower toward the grain feeding cylinder, and the bottom of which is connected to the bottom of the inverted conical saucer. residual rice in an ascending vertical rice polishing machine comprising: a supply port opened in a grain feeding tube between the bottom of the inverted conical saucer and the supply hopper; and a residual rice removal port opened in the bottom of the inverted conical saucer. The ejection device is described.

(Problems to be Solved by the Invention) In the prior invention, the lower end opening of the supply hopper, whose bottom is lower toward the grain feeding tube, extends to the bottom of the inverted conical saucer at the lower end of the grain feeding tube. connected so that Therefore, even if the upward grain feeding spiral is rotating, the structure is such that the rice flowing on the bottom surface of the supply hopper immediately flows directly into the bottom of the inverted conical saucer. However, since the residual rice outlet is opened in a part of the bottom of the inverted conical saucer, if the residual rice outlet is not closed when polishing rice, the supplied rice will spill from the residual rice outlet. In other words, there is a problem that if the remaining rice outlet is forgotten to be closed, the supplied rice will spill out.

This invention prevents the supplied rice from spilling even if the user forgets to close the residual rice outlet.

(Means for Solving the Problem) Therefore, the present application includes a vertical rotating shaft 1 provided in a box-shaped case 17, an upward feeding grain spiral 3 provided at a lower position of the vertical rotating shaft 1, and the above-mentioned A milling roll 4 provided at an upper position of the vertical rotation shaft 1, a horizontal bottom 35 provided at the lower end of the upward feeding grain spiral 3, and a horizontal bottom 35 surrounding the outer periphery of the upward feeding grain feeding spiral 3.

Note that it is possible to use only one of the upper drive shaft 22 and the lower drive shaft 23 and to attach the blower 24 and the suction blower 27 coaxially.

(effect) Next, we will discuss the effect.

The brown rice in the supply hopper 18 is
When grains are fed from the supply port 7 through the hopper 9 to the supply port 7, the grains try to fall from the supply port 7 toward the horizontal bottom 35, but since the upward feeding spiral 3 is rotating, the grains The polishing tube 6 is raised by
Inside, the rice is stirred and polished by the polishing rolls 4 and taken out from the discharge port 11 of the upper case 10.

During this time, the wind blown from the blower 24 fixed to the lower drive shaft 23 of the motor 21 flows into the upper end 15 of the rice milling roll 4 through the blower pipe 16, and passes through the upper end 15 to the milling roll 4. blowhole 32
The rice bran polished by the polishing roll 4 is blown away by the wind blown from the blowhole 32, and is ejected into the rice bran chamber 29 through the holes of the polishing tube 6.

During the rice milling operation, brown rice is constantly supplied from the supply port 7, and the brown rice tries to fall inside the grain feeding tube 5, but the falling brown rice touches the rotating upward feeding grain feeding spiral 3 and immediately It is raised and does not fall to the residual rice removal port 8. Therefore, even if you forget to close the residual rice outlet 8 and it is not covered, the rice will not spill out.

Removal of the remaining rice from the outlet 8 can be performed by reversing the upward grain feeding spiral 3.

(Effect) In the above-described prior invention, the lower end opening of the supply hopper, whose bottom is lower toward the grain feeding tube, is connected to extend to the bottom of the inverted conical saucer at the lower end of the grain feeding tube. ing. Therefore, even though the upward feed spiral is rotating, the rice flowing over the bottom of the feed hopper is
The structure is such that the sputum flows directly into the bottom of the inverted conical saucer. However, since the residual rice outlet is opened in a part of the bottom of the inverted conical saucer, if the residual rice outlet is not closed when polishing the rice, the supplied rice will spill from the residual rice outlet. In other words, if you forget to close the residual rice outlet, there is a problem that the supplied rice will spill out.

However, the present application has a vertical rotating shaft 1 provided in a box-shaped case 17, an upward feeding grain feeding spiral 3 provided at a lower position of the vertical rotating shaft 1, and a vertical rotating shaft 1 provided at an upper position of the vertical rotating shaft 1. A whitening roll 4, a horizontal bottom 35 provided at the lower end of the upward feeding grain spiral 3, and a grain feeding cylinder 5 surrounding the outer periphery of the upward feeding grain spiral 3 and rising above the horizontal bottom 35; A polishing cylinder 6 surrounding the outer periphery of the polishing roll 4, a supply hopper 18 provided on the side of the grain feeding cylinder 5, a supply port 7 opened at an intermediate position between the upper and lower sides of the grain feeding cylinder 5, and the grain feeding cylinder 5. Since this is a residual rice discharge device for an ascending vertical rice mill consisting of a residual rice take-out port 8 that opens at the lower end of the cylinder 5 at a position below the supply port 7, the grain feeding chamber has a horizontal bottom 35. There is a grain feeding tube 5 that rises above the horizontal bottom 35, and such a grain feeding tube 5
The supply port 7 is opened at an intermediate position between the upper and lower sides of the
Since the residual rice outlet 8 is opened at a position lower than the supply opening 7, the residual rice will not be discharged even if the residual rice outlet 8 is open as long as the upward feeding grain spiral 3 is rotated in the normal direction. This prevents grains from scattering due to forgetting to close the lid.
