[0002] The production of broken rice is inevitable during rice processing. Broken rice refers to the damaged portion of rice caused by mechanical forces during processes such as hulling and grinding. Broken rice has a direct impact on the overall quality of rice. For example, broken rice may cook faster than whole rice kernels during cooking, resulting in an inconsistent taste when mixed with other ingredients. From a nutritional perspective, broken rice does not differ significantly from whole rice kernels. However, during storage, the increased surface area of ​​broken rice may make it more susceptible to oxidation or microbial contamination, affecting its nutritional content.

[0023] Example

[0024] A broken rice separation and dust removal device comprises a feed pipe 1 and a separation and dust removal mechanism 2. A fan is installed at the starting end of the feed pipe 1 and is connected to a granary. A valve is installed on the granary. By controlling the opening size of the valve and the output power of the fan, the airflow and rice grain mixture entering the feed pipe 1 are moved at a specified rate and finally discharged from the end of the feed pipe 1. The separation and dust removal mechanism 2 is arranged below the end of the feed pipe 1. The airflow and rice grain mixture discharged from the end of the feed pipe 1 will fall into the separation and dust removal mechanism 2 in a parabolic motion due to gravity. According to the difference in weight, the whole rice grains and the broken rice will fall into the 0021 in turn for further classification and dust removal.

[0025] The separation and dust removal mechanism 2 includes a carrying plate 21 , a top cover 22 , a shielding plate 23 , a discharge port 24 , a guide plate 25 and a discharge pipe 26 .

[0026] The center of the supporting plate 21 and the ground can rotate relative to each other. The lower end of the supporting plate 21 is fixedly connected to the discharge pipe 26. The discharge pipe 26 is rotatably connected to the base 27. The base 27 is arranged on the ground and is equipped with a motor. The motor drives the discharge pipe 26 and the supporting plate 21 to rotate synchronously through the transmission structure.

[0027] Preferably, the transmission structure is a gear set, including a gear 1 and a gear 2 that mesh with each other, the output shaft of the motor and the gear 1 are fixedly connected, and the discharge pipe 26 and the gear 2 are coaxially fixedly connected.

[0028] Preferably, the transmission structure is a transmission belt structure, including two pulleys and a wheel belt, and the two pulleys are fixedly connected to the output shaft of the motor and the discharge pipe 26 respectively.

[0029] The top cover 22 is arranged above the carrier plate 21 and retains a clearance port for the end of the feeding pipe 1 to discharge the mixture. A transparent shell is arranged at the clearance port, which serves the purpose of isolating dust on the one hand and ensuring visibility on the other.

[0030] The top cover 22 and the feed pipe 1 are detachably fixed to each other. The top cover 22 is placed on the carrier plate 21 and is rotatable with the carrier plate 21. The top cover 22 is externally connected to a pipe 1, and the pipe 1 is connected to another fan, which is used to extract the dust that falls into the space of the top cover 22 under the suction action of the fan.

[0031] The arc-shaped baffle 23 is fixed on the base 27, and the discharge port 24 is opened through the bottom of the carrier plate 21. The baffle 23 fits the outer side of the discharge port 24, and the baffle 23 does not completely cover the outer side of the discharge port 24. Guide plates 25 are arranged at intervals in the exposed part of the discharge port 24. When rice grains or broken rice pass through the discharge port 24 and enter the guide plate 25, the inclined guide plate 25 can use gravity to guide the guide plate 25 to the place where rice grains are collected. The guide plate 25 and the base 27 are fixed.

[0032] Furthermore, groove 1 211 and groove 2 212 are opened in the supporting plate 21, groove 1 211 is located on the inner side of groove 2 212, and according to the running trajectory of the parabola and actual factors, groove 1 211 is used to receive whole rice grains, and groove 2 212 is used to receive broken rice.

[0033] The discharge port 24 is provided at the bottom surface of the second trough 212 for recovering broken rice.

[0034] The discharge pipe 26 is used to communicate with the trough 1 211 for recovering complete rice grains.

[0035] In summary, the present application designs a rotatable carrier plate 21 and allows the carrier plate 21 to fully contact the rice grains and broken rice, thereby extending the residence time of the rice grains and broken rice on the carrier plate 21 to improve the dust removal efficiency during the broken rice separation process.
