[Prior art]
[Patent Document 1]
JP, 7-132239, A Conventionally, the rice milling machine provided with the milling part of the front-lowering arrangement which pressure-feeds and refines the brown rice which received from the input hopper to the supply mouth, the resistance board which secures the whitening pressure of the milling part, the de-airing blower, etc. Are known. In this rice milling machine, when the whitening process proceeds and the brown rice in the input hopper is exhausted, the pumping power of the milling section decreases, and the remaining part of the input rice is unavoidable due to the adsorption action of the demolding blower, etc. Residual rice was mixed into the next whitening treatment or stayed for a long time until the next whitening treatment, causing quality problems. In particular, the coin-type automatic rice milling machine has problems such as a sense of incongruity due to the mixing of residual rice by an antecedent whose brand grade is unknown, and a decrease in taste due to mixing of different brands of rice.
[0003]
For this problem, a rice milling machine disclosed in Patent Document 1 has been proposed. This rice milling machine has a low-tilt discharge outlet side of the milling section, and the rice detection sensor provided at the feeding port stops the dehuller blower after the brown rice in the hopper is exhausted, and the milling section is further opened with the resistance plate open. By continuing the operation, the above-mentioned problem is solved by controlling the operation so that the remaining rice is discharged to the end by the inclination of the milling portion without requiring a complicated configuration.
[0004]
[Problems to be solved by the invention]
However, since the rice milling machine having the above configuration continuously operates the milling unit and discharges the residual rice inside by the feeding action of the milling roll, it takes a lot of time to discharge all the residual rice. Since the finish of the whitening process is adversely affected by the pressure difference between the front and rear positions in the tilted spermatozoon, the tilt angle has to be kept small in terms of sperm quality. Therefore, the increase in the waiting time of the user until the end of the discharge and a decrease in the utilization rate due to the increase in the occupation time of the rice milling machine are caused.
[0005]
An object of the present invention is to provide a rice mill capable of promptly discharging cereals without remaining in the machine body after the milling process while ensuring milling quality with a simple configuration.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the invention according to claim 1, a pearling unit for milling process by pearling roll receives cereals from the feed opening, and an openable resistive plate giving the outlet resistance of the pearling portion In the rice milling machine, the milling unit is provided with a shutter that can close the inlet side of the supply port, and the blower is connected to the supply port of the milling unit via the supply port air passage and has no grains. a sensor for detecting provided, further, the detection signal of the sensor, closed chain of the shutter, and performs sending wind to the open- Contact and supply port air flow passage of the resistive plate.
[0007]
When the input of cereals is exhausted, the sensor detects this, opens the resistance plate, closes the shutter, and further controls the operation to send air to the supply port of the milling section through the supply port air passage, closing the supply port input side with the shutter Therefore, the air blown by the supply port air flow path flows out from the discharge port through the inside of the finer portion, and the cereal remaining in the finer portion is discharged together with this air flow.
[0008]

In this rice milling machine, when the rice is milled under the removal by the removal air ventilation means, the remaining grains are adsorbed by the removal pressure of the removal net or the like of the polishing portion by controlling the operation to stop the ventilation means. Without being exhausted, it is efficiently discharged from the outlet by the exhaust air .
[ 0009 ]
【The invention's effect】
The rice mill of the present invention has the following effects.
In the above rice milling machine, the cereals remaining in the milling unit are discharged together with the air flow from the supply port to the discharge port of the milling unit by a predetermined operation control, so that no special configuration change is required in the milling unit. , By simply adding air blowing means to the feeding port of the milling unit, the milling quality is ensured, the waiting time of the user is suppressed, and the rotation rate of the milling machine is reduced due to the increase in the occupied time of the rice milling machine. The grain remaining inside can be quickly discharged from the scouring part without incurring any other problem.
[ 0010 ]
When it is configured so that the air removal means is stopped in conjunction with it, the cereals remaining from the discharge port efficiently by the supply port air blowing without adsorbing the cereals remaining due to the ventilation pressure on the dewatering net etc. Therefore, it is possible to quickly discharge the cereals remaining from the milled portion while ensuring the function of removing the debris by the ventilation means.
[ 0011 ]
When the operation of controlling the residue discharge operation at the end of the whitening process based on the detection signal of the sensor, the residue is reliably discharged every time the whitening process is performed. Without causing an increase in waiting time and a decrease in utilization rate, it is possible to solve problems of discomfort and processing quality due to the mixing of the preceding processed products.
