Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rice extraction, in particular to an extraction device for reducing the moisture content of rice. Background Art
[0002] Rice easily absorbs moisture during storage, especially in high-temperature environments, which can cause it to heat up and become moldy. Exhaust equipment can remove the hot and humid air from the grain pile, reducing the temperature and humidity, and keeping the rice dry and fresh.
[0003] When using existing exhaust equipment, the exhaust pipe is usually inserted directly into the rice. However, the length of the exhaust pipe is relatively fixed and cannot be extended when inserted into the rice. Therefore, when exhausting thicker rice, it cannot be inserted into the interior, that is, a good exhaust effect cannot be achieved. In addition, when the current exhaust equipment discharges air, it discharges the air directly on the exhaust equipment, which may cause the hot and humid air to be blown to the surface of the rice, thereby affecting the quality of the surface rice.
