Description

Technical Field

[0001] The present invention belongs to the technical field of rice drying, and particularly relates to a rice drying and processing device for grain and oil production. Background Art

[0002] Rice, also known as paddy rice, is a food made from paddy after processes such as cleaning, hulling, milling, and finished product finishing. Rice is the main food for people in most parts of China. Rice contains about 75% carbohydrates, 7% - 8% protein, 1.3% - 1.8% fat, and is rich in B vitamins, etc. The carbohydrates in rice are mainly starch, and the protein contained is mainly oryzenin, followed by glutelin and globulin. The biological value of its protein and the composition ratio of amino acids are higher than those of cereal crops such as wheat, barley, millet, and corn, with a digestibility of 66.8% - 83.1%, which is also relatively high among cereal proteins.

[0003] Rice drying is an important process in the rice processing. Without drying, the water content of rice is relatively high, and it is prone to mildew after being stored for a long time. Mildewed rice is inedible. Therefore, rice needs to be dried before storage. At the same time, broken rice is easily produced during the rice processing. The admixture of broken rice in rice will reduce the economic value of rice, and broken rice needs to be screened. Existing rice dryers generally do not have an automatic screening function and can only dry rice. After drying, the rice still needs to be transferred to a screening machine for screening. Transferring rice back and forth not only easily causes wear of rice grains, increasing the number of broken rice, but also is time-consuming and laborious. Therefore, a rice drying and processing device for grain and oil production is proposed. Summary of the Invention
