Description

Technical Field

[0001] The present invention relates to the technical field of rice packaging devices, and in particular to a rice packaging device capable of reducing the temperature of rice. Background Art

[0002] Rice processing generally requires screening, husking, color sorting, polishing and other processes to produce polished rice. The polished rice is placed in a rice storage hopper, and then the polished rice in the rice storage hopper is placed in a rice packaging machine for packaging.

[0003] The existing rice packaging device that can lower the temperature of rice uses a stirring mechanism to stir the rice in the silo during use, and cooperates with an exhaust fan to discharge the heat in the silo to reduce the temperature of the rice. However, since the rice is in a stacked state, the heat cannot be dissipated quickly, which leads to poor cooling effect and affects the packaging effect. In addition, the existing rice packaging device that can lower the temperature of rice cannot detect the temperature of the cooled rice during use, which makes it impossible for the staff to know whether the rice has been cooled enough. It is also inconvenient to control the power of the heat dissipation mechanism according to the cooling effect, resulting in low performance. Therefore, a rice packaging device that can lower the temperature of rice is urgently needed to solve the existing problems. Summary of the Invention

[0004] The object of the present invention is to provide a rice packaging device capable of reducing the temperature of rice in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A rice packaging device capable of lowering the temperature of rice comprises a silo, an inclined feed pipe is provided at the bottom end of the silo, an inner cylinder is installed in the feed pipe, a through hole is provided on the outer wall of the inner cylinder, a rotating shaft with a hollow structure is installed in the inner cylinder, air holes are provided on the outer wall of the rotating shaft, and spiral blades are also fixed on the outer wall of the rotating shaft, a driving motor is installed at one end of the feed pipe, a universal joint is provided at the other end of the rotating shaft, an air guide pipe is connected to one end of the universal joint, an air pump is provided at the other end of the air guide pipe, an exhaust fan is installed on one side of the upper end of the feed pipe, and an exhaust pipe is installed on the air suction port of the exhaust fan.

[0007] Furthermore, a connection port is reserved on one side wall of the feed pipe, and the bottom of the silo is connected to the connection port via a flange.

[0015] Furthermore, the air guide tube is fixedly connected to the universal joint and the output port of the air pump.

[0016] By adopting the above technical solution, during the rice transportation process, the high-pressure gas generated by the air pump passes through the air guide pipe, the universal joint, and the inside of the rotating shaft and is discharged through the air holes, acting in the gaps between the rice, thereby taking away the heat on the surface of the rice and discharging it through the through holes.

[0017] Furthermore, one end of the air extraction pipe is connected to the air extraction port of the air extractor, and the other end of the air extraction pipe is connected to the feed pipe.

After the injection is completed, close the cover through the pneumatic rod. During the rice packaging process, place the packaging bag under the discharge pipe. At this time, the drive motor drives the rotating shaft to rotate, thereby causing the spiral blades to transport the rice. During the rice transportation process, the high-pressure gas generated by the air pump passes through the air guide pipe, the universal joint, and the inside of the rotating shaft and is discharged through the air hole, acting in the gap between the rice, thereby taking away the heat from the surface of the rice and discharging it through the through hole.

When the detection result is greater than the set value, it means that the cooling is not up to standard, and the indicator light is controlled to display red to remind the staff. When the detection result is up to standard, the indicator light is controlled to display green. At this time, the staff can control the output power of the air pump, the vacuum pump and the drive motor according to the color of the indicator light, thereby achieving better cooling of the rice and high performance.
