[0029] The intelligent ball roll polishing machine comprises two polishing chambers 1 arranged in an up-down manner. One end of the polishing chamber 1 is provided with an inlet 11, and the other end of the polishing chamber 1 is provided with an outlet 12. A pushing roller 13 and a polishing roller 14 are arranged in the polishing chamber 1. The pushing roller 13 is arranged on the side close to the inlet 11, and is used to push the rice from the inlet 11 to the right to the polishing roller 14 and then discharge from the outlet 12.

[0030] In the embodiment, the two polishing chambers 1 are arranged in a reverse manner, and the outlet 12 of the upper polishing chamber 1 is matched with the inlet 11 of the lower polishing chamber 1. Specifically, a feeding hopper 2 is arranged at the inlet 11 of the upper polishing chamber 1, and an upper discharge nozzle 3 is arranged at the outlet 12 of the upper polishing chamber 1. A receiving hopper 4 is arranged at the inlet 11 of the lower polishing chamber 1, and the receiving hopper 4 is arranged below the upper discharge nozzle 3. A lower discharge nozzle 5 is arranged at the outlet 12 of the lower polishing chamber 1.

[0031] The bottom of the lower polishing chamber 1 is further provided with a bran collecting hopper 6 for collecting bran generated during polishing.

[0032] The polishing roller 14 is provided with roller ribs 141 arranged in multiple rows on the surface of the polishing roller 14. The front side of the roller rib 141 in the rotating direction is provided with a polishing surface 144, and the polishing surface 144 is a quarter spherical surface. The polishing surface 144 can polish the rice through the spherical surface, so as to reduce the polishing pressure, greatly reduce the occurrence of broken rice during polishing, and make the polishing effect better.

[0033] The roller ribs 141 of adjacent two rows are arranged alternately, and each row of roller ribs 141 comprises a spiral segment 142 and a straight segment 143. The roller ribs 141 in the spiral segment 142 are arranged along a spiral line, and the arrangement direction of the roller ribs 141 in the straight segment 143 is parallel to the axial direction of the polishing roller 14. The spiral segment 142 is arranged at one end close to the inlet 11, and the straight segment 143 is arranged at one end close to the outlet 12.

[0034] The spiral section 142 is used to apply forward moving thrust to the rice, ensuring that the rice moves from one end of the polishing roller 14 to the other end, but the polishing effect of the spiral section 142 on the rice is weak. The straight section 143 has a better polishing effect on the rice. Therefore, in the upper and lower polishing chambers 1, the rice is first polished by the straight section 143 after being applied with sufficient thrust by the spiral section 142, ensuring the polishing effect on the rice.

[0035] In the embodiment, the roller ribs 141 of the upper and lower polishing rollers 14 have different spiral directions, and the same motor is used to drive the two polishing rollers 14 to rotate in the same direction, so that the same motor can drive the two polishing rollers 14 to push the rice in opposite directions. The upper and lower polishing chambers 1 are used to polish the rice respectively in the embodiment, which can increase the polishing stroke and improve the polishing effect and the single-machine output of the polishing machine.

[0036] In addition, the polishing roller 14 is provided with spray holes 145, which correspond to the roller ribs 141 one by one, and the spray holes 145 are arranged at the rear side of the corresponding roller ribs 141 along the rotating direction. The spray holes 145 are used to spray clean water or nutrient liquid to the rice, which can blow away the bran powder generated during polishing, attach nutrients or spices to the surface of the rice, increase the water content on the surface of the rice, and improve the polishing effect.

[0037] The spray holes 145 communicate the inside and outside of the polishing roller 14, the inside of the polishing roller 14 is also connected to the water source 8 through the water pump 7, and the polishing roller 14 is also provided with a heating pipe 146 for heating liquid.

[0038] The polishing chamber 1 is provided with a humidity sensor 15 and a temperature sensor 16. The humidity sensor 15 is signal connected to the water pump 7, which is used to control the rotating speed of the water pump 7 according to the humidity in the polishing chamber 1. The temperature sensor 16 is signal connected to the heating pipe 146, which is used to control the opening and closing of the heating pipe 146 according to the temperature in the polishing chamber 1.

[0039] Specifically, when the humidity sensor 15 detects that the humidity is higher than the preset maximum value, the rotating speed of the water pump 7 is reduced to reduce the water supply, and when the humidity sensor 15 detects that the humidity is lower than the preset minimum value, the rotating speed of the water pump 7 is increased to increase the water supply, so that the water content on the surface of the rice can be maintained within a suitable range, ensuring the polishing effect.

[0040] In addition, when the temperature sensor 16 detects that the temperature is higher than the preset maximum value, the heating pipe 146 is turned off to reduce the water temperature, and when the temperature sensor 16 detects that the humidity is lower than the preset minimum value, the heating pipe 146 is turned on to increase the water temperature, so that the temperature of the rice can be maintained within a suitable range, avoiding the rice from being broken due to high temperature, thereby reducing the broken rice rate.

[0041] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
