Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice mixing device for mixing processed rice (fortified rice) coated with vitamin supplements, flavor, taste improvers, etc. into polished rice in a quantitative ratio.

Conventional rice mixing devices measure and feed each grain of rice to be mixed into a vertically divided tank, and mix the rice by adjusting the flow rate by opening and closing a shutter. The commonly used method is to have a screw conveyor erected in the center of a vertical cylindrical tank, and a predetermined ratio of polished rice and processed rice are put into the tank and stirred and mixed to obtain mixed rice. In the former, the opening/closing operation of the shutter has a slight effect, which tends to result in incomplete rice mixing, while in the latter, processing capacity is improved, but grains are mixed under pressure, which has the disadvantage of causing broken rice. be.

In order to solve the above-mentioned drawbacks, the present invention provides a mixed rice tank with an outlet for processed rice mounted inside the cylindrical body of the mixing hopper in which a rice grain dispersion device is housed. A rice milling tank and a processed rice tank are installed, each connected to a multi-blade measuring rotor with a unique structure, and the rotor discharge port on the rice milling tank side is connected to the grain feeding port of the mixed rice tank. At the same time, by connecting the rotor outlet on the processed rice tank side to the processed rice outlet of the mixed rice tank, the rotational speed of each weighing rotor can be adjusted appropriately to separate the polished rice and processed rice. While adjusting the discharge amount to a predetermined mixing ratio, both rice grains are mixed by flowing down into the rice mixing tank, and then dispersed by the rice grain dispersion device in the mixing tank and flowing down into equal parts and mixed. The purpose of the present invention is to develop and provide a high-performance device for mass-producing high-quality fortified polished rice in which any processed rice is mixed in a predetermined mixing ratio without producing broken rice.

The present invention will be explained with reference to embodiment figures. Number 1 in the figure is a funnel-shaped mixing hopper, and the hopper 1 houses a rice grain dispersion device 3 consisting of a dispersion impeller 2 that rotates or rotates, and a fitting opening is provided at the top of the cylinder. 4, a discharge port 5 is provided at the bottom of the cylinder, and a grain feeding port 6 is separately provided at the top, a grain discharging port 7 is provided at the bottom, and an outlet for processed rice is provided inside the cylinder. A tank 9 for mixed rice equipped with a hopper 8 is provided, and the cylindrical body of the tank 9 is fitted into the fitting opening 4 of the hopper 1 to be integrally installed. A tank 10 and a tank 11 for processed rice are respectively arranged as appropriate, and a relatively large multi-blade wheel body 13 is rotatably mounted on a rotating shaft 14 via a cart in a cylindrical body discharge part 12 of the rice polishing tank 10. A shaft-mounted multi-blade measuring rotor 15 is connected, and its discharge port 16 is connected to the grain feeding port 6 of the mixed rice tank 9 through a flow pipe 17, and the processed rice tank 11 is connected to a cylinder. A multi-blade measuring rotor 21 in which a relatively small multi-blade wheel body 19 is rotatably attached to a rotating shaft 20 via a truck is connected to the discharge section 18, and its discharge port 22 is connected to the multi-blade weighing rotor 21, which has a relatively small multi-blade ring body 19 rotatably attached to a rotating shaft 20 via a truck. It is connected to the processed rice outlet 8 in the tank 9 by a flow tube 23.

Since the above configuration is adopted, polished rice is stored in the rice polishing tank 10, and any processed rice is stored in the processed rice tank 11.
When the device is started, the multi-blade wheel body 13 or 19 of each multi-blade measuring rotor 15 or 21 rotates to remove polished rice from the rice milling tank 10 and from the processed rice tank 11, respectively. However, when processed rice such as vitamin-fortified rice, amylase, cyclodexitron, and surfactant-coated rice is mixed into polished rice, the mixing ratio is usually in the range of 0.1 to 1.0% (weight ratio). , and each of the metering rotors 15 or 21 is connected to each of the multi-blade wheels 13 or 1 in advance.
If each empty volume between the blades of 9 and the volumetric weight of processed rice and polished rice are measured, each wheel 13 or 19
By increasing or decreasing the rotational speed of each metering rotor 15 or 21, the flow rate of each metering rotor 15 or 21 can be set to a predetermined mixing ratio. Therefore,
From each measuring rotor 15 or 21 whose rotational speed is adjusted respectively, polished rice and processed rice are discharged at respective flow rates at a predetermined mixing ratio, and each rice grain flows down each flow tube 17 or 23. The mixed rice is mixed in the mixed rice tank 9, and flows down from the grain discharge port 7 of the tank 9 onto the impeller 2 of the rice grain dispersion device 3 provided in the mixing hopper 1. Due to the rotation, the mixed rice is dispersed in the cylinder and falls in equal parts, mixed sufficiently and accumulated at the bottom of the cylinder, and the mixed rice is discharged from the discharge port 5 of the mixing hopper 1 and conveyed. Then, it is left to the next process (such as a weighing and bagging device).

Claim 2 provides that each of the multi-blade measuring rotors 15 or 21 is fixed by fitting a multi-blade wheel body 13 or 19 made of a soft material to the outer peripheral surface of the rotating cart 24 or 24A. Therefore, when ejecting rice grains by rotating the wheel,
Since the end portion of the blade moves while being in flexible contact with the inner circumferential surface of the cylinder, it is possible to completely prevent rice grains from being caught between the inner circumferential surface of the cylinder and the wing piece, and to break the rice into broken rice. This has the effect of making body replacement work simple and easy.

According to the third aspect of the present invention, the mixing hopper 1 has a horizontal screw conveyor 25 connected to its discharge port 5, so that the conveying action caused by the rotation of the screw causes the gutter to be removed. The rice grains flowing inside can be further mixed in an agitated manner to increase the mixing precision, and the discharge port 26 is directly connected to the next process, such as a weighing and bagging device, to form a continuous flow process, which improves the work efficiency. This has the effect of significantly improving

In this way, the rice mixing device of the present invention operates by adjusting the rotational speed of each multi-blade measuring rotor with a unique structure connected to the rice milling tank and the processed rice tank, thereby obtaining a predetermined mixing ratio from each tank. Each grain of rice is discharged by the flow rate and mixed into the rice mixing tank, and the mixed rice is dispersed in flight by the mixing hopper and falls evenly to mix thoroughly. The rice is sufficiently mixed using a highly accurate mixing ratio, and the mass production of high quality fortified mixed rice without broken rice can be reliably, smoothly and quickly achieved.
