[Conventional technology]

In the conventional vertical-axis type grain refiner, it is difficult to discharge the remaining grains at the end of milling. In other words, there is a problem that the grain supply device or the porous wall debranching whitening pipe and the like must be removed to scrape out the residual grain by hand, which is not only very troublesome but also cannot be completely discharged. .

[Problems to be solved by the invention]

An object of the present invention is to solve the above problems and provide a residual grain discharging device for a vertical axis type grain mill that can easily and quickly discharge the residual grains at the end of the polishing. And

[Means for solving problems]

In order to achieve this object, the present invention has the following configuration.

A spiral trochanter and a grain trochanter are axially inserted into a vertical shaft that is rotatably provided in an upright standing multi-walled bran-removing white barrel, and the perforated-wall bran-removing white barrel and the grain trochanter are the main parts. The lower part of the grain mill is connected to the grain supply part and the upper part is connected to the grain discharge part to form a vertical grain mill. Then, an arbitrary blast port is provided at the lower end of the spiral trochanter, and a residual grain discharge port having an opening / closing valve is provided on the lower side of the grain chamber to form a residual grain discharge device for a vertical type grain mill. To do.

[Work]

The grain supplied to the spiral trochanter from the grain supply unit of the vertical axis type grain refiner is lifted by the spiral trochanter, and is a fine grain mainly composed of the porous wall-excluding rice bran and the trochanter. She is licked in the room. The milled grain is discharged from the grain discharge section and sent to the next step. Then, when the opening and closing valve is opened, the grain remaining at the end of the milling is communicated with the grain chamber and the residual grain discharge port, and is sequentially discharged by the jet action from the jet port provided at the lower end of the spiral trochanter. .
