Abstract
Description
Technical Field
[0001] The utility model relates to rice processing auxiliary equipment, in particular to a device for removing impurities and stones used in rice processing. Background Art
[0002] Rice, also known as rice, is the fruit of the plant of the genus Oryza in the family Gramineae. The finished product after the rice grains are shelled and ground into coarse skin is edible. Rice is one of the main foods for humans and one of the main foods for Asians. About half of the world's population eats rice. It is commonly used as a staple food in Asia and Chinatowns around the world. In addition, rice can also be used as a general term for a type of food, such as rice, millet, yellow rice, glutinous rice, black rice, coix seed, corn, etc. In order to ensure the quality of rice after production, impurities such as stones, sand and rice husks are generally removed through stone removal and impurity removal devices.
[0003] Patent No. CN219503201 U in the prior art discloses a device for removing impurities and stones for rice processing, which includes an externally arranged shell, a support leg arranged at the bottom end of the shell, a feed hopper arranged at the top end of the shell, a vibrating screen and an inclined plate installed on the shell at the bottom end of the vibrating screen are installed on the top of the inner side of the shell, and also includes a discharge port, a collecting hopper, a diversion assembly and a support column. The bottom of one side of the shell is provided with a discharge port, the shell on one side of the vibrating screen is provided with a sewage outlet, a bearing platform is fixed on the shell outside the sewage outlet, and a diversion assembly is provided between the feed hopper and the shell; the diversion assembly includes an oblique triangular tube, a vertical tube and an inclined partition plate, the top end of the oblique triangular tube is fixed on the feed hopper, the bottom end of the oblique triangular tube is fixed with a vertical tube, and a plurality of inclined partition plates are provided on the bottom inclined wall of the oblique triangular tube. The utility model has a novel structure and an ingenious conception, and can evenly add rice to the vibrating screen, thereby improving the efficiency and effect of the vibrating screen in removing impurities and stones from rice.
[0004] However, the patents under the existing technology have the following disadvantages:
[0005] (1) The impurity and stone removal device for rice processing of this utility model is only provided with a layer of vibrating screen, which can screen out the gravel and debris in the rice. However, the gravel and debris are also divided into different sizes. Fine sand and gravel are smaller in volume than rice, and the gravel blocks are larger in volume than rice. During screening, the vibrating screen needs to be replaced to completely screen out the large and small debris, which makes screening the debris more cumbersome.
[0006] (2) The vibration structure of the impurity removal and stone removal device for rice processing of this utility model does not have a buffering function. The lack of a buffering function may result in uncontrollable vibration intensity during the impurity removal process. On the one hand, some impurities cannot be effectively separated, affecting the quality of rice; on the other hand, excessively strong vibration may damage rice grains, affecting their taste and nutritional value.
