Apparatus for washing and drying rice

The present invention relates to a device for washing rice so that rice can be cooked without washing by removing the fine rice bran or fine foreign matters attached to the surface of the rice cleanly. The present invention relates to a rice washing and drying apparatus capable of preventing water and at the same time reducing water consumption.

Since rice is packaged and processed through a processing process such as rice milling or tailing process, the fine rice bran and fine foreign substances generated during this processing are packaged as attached to the surface of white rice. It was necessary to wash clean.

In order to improve this point, there is a known method and apparatus for washing rice before packing so that it is not necessary to wash the rice before the rice is cooked. However, the conventional rice washing technique uses a separate dehydration and drying process after washing rice in water. Due to the long contact time with water, there is a problem that there is a great risk of loss of nutrition and quality deterioration.

In addition, according to the conventional rice washing technology, there is a problem that the amount of sewage to be treated increases at the same time the amount of water used for washing increases.

The present invention is designed to solve the problems as described above, an object of the present invention, to clean the rice to cook without removing the fine rice bran or fine foreign matter attached to the surface of the rice during the processing process to clean It is to provide a device for drying after.

Another object of the present invention is to provide a rice washing and drying apparatus that can reduce the amount of water and at the same time reduce the amount of water used to reduce the time the rice is in contact with water in washing the rice. .
