Ceramic-cutting rice milling machine
Ceramic cutting rice milling technology is a processing technology that uses cutting blades made of ceramic to peel off the surfaces of brown rice. Existing friction-type rice milling technology damages rice grains due to high processing pressure, but ceramic- cutting rice technology has less damage and lower processing temperature than friction-type rice technology, thereby reducing power by more than 30%.

Cutting-type dry rice washing machine
Cutting dry rice semi-technology is innovative technology that can reduce the turbidity of rice to less than 40 ppm, and is more efficient than the conventional friction technology. Dry semi-technology is a technology that prevents water pollution by water washed off rice, and rice steel collected is used for feed and fertilizer. This is expected to be effective in preventing environmental pollution with eco-friendly virtuous cycle materials.
The CEO of the company remarked, “We believe that creative thinking is the best service. We will always create the best products to become a reliable company that is always by your side,” adding, “We will become a growing global company that cares for our customers and we welcome your support and interest.”
