Description

Technical Field

[0001] The utility model belongs to the technical field of rice dryers, and particularly relates to an organic rice dryer with a screening function. Background Art

[0002] Organic rice is a kind of rice grown entirely by natural farming methods. It is a food made from paddy rice through processes such as cleaning, hulling, milling, and finished product sorting. Compared with ordinary rice on the market, organic rice contains more trace elements such as iron, magnesium, calcium, and vitamin C, while the content of heavy metals and carcinogenic nitrates is relatively low.

[0003] During the processing of organic rice, it is necessary to clean the rice to remove surface impurities. After cleaning, the organic rice needs to be dried by a dryer to facilitate subsequent storage of the rice.

[0004] During the drying process, too high drying temperature will cause nutrient loss of organic rice and make the organic rice brittle, resulting in an increase in the broken rice rate. At the same time, the rice rolls inside the drying device, and the friction between the rice grains and between the rice grains and the equipment will also cause broken rice to be produced. Moreover, broken rice will also be produced during processes such as milling. Currently, rice dryers generally use single-duct hot air blowers, and the drying effect on rice is not good. The above problems will seriously affect the quality of organic rice. Summary of the Utility Model
