Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a residual rice cleaning device for a rice milling machine that blows and cleans rice grains remaining in a milling chamber.

Conventional technology and its problems In general rice milling equipment, some white rice remains in the milling chamber after milling is finished, and the remaining rice mixes with the next milled rice, resulting in mixed rice of different types such as non-glutinous rice, glutinous rice, and immature grains. This often leads to deterioration in the quality or taste of polished rice.

In particular, with coin-operated rice milling equipment, each user brings in a variety of rice grains of different varieties, production areas, etc. and mills them individually.
The above-mentioned generation of mixed rice has the problem of causing dissatisfaction among users, and there has been a long-awaited demand for improvement of the device.

Purpose of the Invention In view of the above-mentioned points, the present invention provides a blast hole connected to an air compressor in the milling chamber so that the remaining rice grains are blown away after milling is completed to clean the interior of the milling chamber. The present invention provides a residual grain rice cleaning device for rice milling equipment that eliminates the disadvantages of conventional equipment that generate mixed rice of different types as mentioned above, and that easily and reliably cleans the inside of the milling chamber and ensures high quality polished rice for each type of milled rice grain. The purpose is to provide.

Structure of the Invention The residual grain rice cleaning device of the rice milling apparatus of the present invention comprises a milling chamber formed by pivoting a milling trochanter in a porous wall milling cylinder for removing bran, and a resistance lid provided on one side of the milling chamber. In a rice milling device that is provided with a rice grain discharge port on the other side and a rice grain supply port on the other side, a cleaning blowhole for blowing away residual rice grains is provided on the inner wall surface of the polishing chamber, and the blowhole is It has a configuration characterized in that it is connected to an air compression device.

Description of examples The configuration of the present invention will be explained based on the drawings.

A fuselage wall 2 is installed inside the horizontal machine cylinder 1 to create a whitening chamber 3 and an air chamber 4.
A porous wall polishing cylinder 5 for removing rice bran is mounted on the outer periphery of the polishing chamber 3, a rice bran removing chamber 6 is formed outside of the polishing cylinder 5, and a resistance lid 7 is provided on one side of the polishing cylinder 4. A rice grain discharge port 8 and a rice grain supply port 9 are provided on the other side, and a main pipe shaft 13 equipped with a polishing trochanter 11 and a spiral trochanter 12 equipped with a blast groove 10 is fitted inside the polishing chamber 3. In addition, each through hole 14 provided in the rear half shaft portion of the main pipe shaft 12 is communicated with the air chamber 4,
A rotating pulley 15 is attached to the shaft end so that the rotating pulley 15 rotates, and a cleaning blow hole 16 for blowing away remaining rice grains is provided at the bottom of the side wall 2 of the milling room 3. The hole 16 and the air compressor 17 are connected by a feed pipe 20 equipped with a solenoid valve 18, an air pressure regulating valve 19, etc., 21 is a blower connected to the air chamber 4, and 22 is a rice bran discharge port. Further, the rice grain supply port 9 is provided with a rice grain detection device W23 consisting of a sensor that detects the presence or absence of rice grains, and when the detection device 23 detects that there are no rice grains inside the rice grain supply port 9, a detection signal is sent. starts a timer (not shown), followed by l! at a predetermined time. After 1 (several seconds), the valve opening/closing device 24 consisting of a solenoid is operated to open the resistance lid 7, and the solenoid valve 18 provided on the air compressor 17 side is operated to supply compressed air to the blowhole 16. Furthermore, when the cleaning action is completed within a predetermined period of time (several minutes), the resistance lid 7 and the air compressor 17 are configured to automatically return to their old state.

The operation of the above configuration will be explained.

When raw brown rice is put into a rice grain tank (not shown) provided in the rice grain supply port 9 and the device is started, the brown rice flows into the milling chamber 3 and is fed by the rotation of the spiral rotor 12. The rice grains are agitated by the rotation of the polishing trochanter 11 and polished by grain-by-grain friction, and the bran layer on the surface of the rice grains is peeled off by the blast action from the blast groove 10 and flows out of the polishing cylinder 5, and the rice bran powder is removed. The rice grains are discharged from the machine through the rice bran chamber 6 through the rice grain discharge port 22, and the polished white rice is taken out of the machine from the rice grain discharge port 8. At the end of milling, some white rice will remain in the milling room 3, but Hon 1i! II! 1, a rice grain detection device 23 installed in the rice grain supply port 9 detects the absence of rice grains in the supply port 9, and operates the valve opening/closing device 24 in a timely manner based on the detection signal to close the resistor lid 7. At the same time, the solenoid valve 18 is operated to open the air compressor W mentioned above.
Since compressed air is supplied to the blast hole 16 from the blast hole 117, rice grains remaining in the milling chamber 3 are swept away by the blast action from the blast hole 16 and are completely discharged from the opened rice grain outlet 8. The whitening room 3 will be cleaned. Further, at the time when the cleaning operation in the whitening chamber 3 is finished, the resistance lid 7 and the air compressor 17 stop operating at a proper time and return to a state where the whitening operation can be continued.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, as described in detail, a blast hole connected to an air compressor is provided in the milling chamber, so that rice grains remaining after milling are blown away to clean the inside of the milling chamber. Therefore, it is possible to completely eliminate the above-mentioned disadvantages of the conventional equipment that generate mixed rice of different types, and to easily and reliably clean the inside of the milling chamber and ensure high-quality milled rice for each type of milled rice grain, improving its quality and taste. It has the effect of being able to maintain good properties.
