Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an attached wrinkle removing apparatus for removing wrinkles adhering to the surface of white rice that is discharged from a cereal chamber in a horizontal grinding type pulverizer.
[0002]
[Prior art]
Conventionally, in the horizontal grinding type pulverizer as described above, the cocoon produced by the sperm action in the cereal chamber leaks from the descreening screen together with the demolding wind, and is removed. It is well known that the koji is not sufficiently removed due to the heat generated by the whitening action in the cereal chamber, and is attached to the surface of the white rice and taken out.
[0003]
[Problems to be solved by the invention]
As described above, in the conventional horizontal grinding type pulverizer, there is a drawback that the surface of the white rice from which the discharge of the cereal chamber is taken out is attached to the surface of the rice and loses the gloss of the white rice, thereby impairing the commercial value.
[0004]
[Means for Solving the Problems]
Therefore, in order to eliminate this drawback, the present invention has a grinding chamber in which the grinding roll is surrounded by a descreening screen and formed between the grinding roll and the descreening screen. The supply of the room feeds brown rice from the waste and the white rice is taken out from the discharge. The cereal chamber discharge gutter is communicated with the white rice falling flow path, and the white rice discharge port is opened to the machine wall portion of the discharge gutter corresponding to the upper part of the grinding roll. By providing discharge ports at multiple locations on the wall of the discharge grinder across the axis of rotation of the grinding roll , the white rice drop path in the white rice drop flow path is lengthened, and the action of removing adhering soot due to the rising air flow is achieved. As the size of the rice grows, the temperature of the white rice is effectively reduced. Separation and removal of the attachment bran is to be effective by the rice layer is relatively thinner and updraft falling into the road.
[0005] The upper part of the white rice drop passage communicates with the evacuation chamber formed around the outside of the decontamination screen through which the suction exhaust air blows through the suction port that is opened higher than the white rice discharge port. As a result, the action of removing the attached soot is improved, and the cost becomes low as compared with the case where a device for raising an updraft that blows up the white rice falling channel is provided independently.
[0006] Further, if a blower outlet for blowing the removal wind from the inside of the grinding roll is opened at the end surface portion of the grinding roll that passes by the side of the white rice discharge outlet, The removal of the white rice taken out through the discharge port and the temperature reduction of the white rice are promoted.
[0007] In this case, by providing the discharge vane at the front of the discharge port, the discharge blade further facilitates the removal of the white rice, and the back of the discharge blade has a coarser white rice density and the discharge port. Blows the wind from the air well.
