Description

Technical Field

[0002] Rice refers to the rice grains that have not been husked. Botanically, it belongs to the subspecies of Oryza sativa in the subgenus Oryza of the genus Oryza in the family Gramineae. Humans have identified a total of 22 types of rice, but the only one used in bulk trade is the common type of rice.

[0003] Before rice is stored, in order to prevent it from getting moldy due to storage in a closed space, it must generally be husked and dried. Traditional husking and drying is generally done by exposing it directly to the sun, but this not only requires a large open space, but also requires manual or machine-assisted lifting and turning of the material during the drying process. Although existing drying boxes and other equipment can achieve indoor drying, such machinery needs to continuously transport the rice during use, and the entire process requires continuous manual control.
