The RTFC or known as the The Rice Terrace Farmers Cooperative processed samples of newly harvested rice and sent them to PhilRice for testing the prototype. The air screen machine was designed and built for the Cordillera Heirloom Rice Project. The machine has a fan, which will blow the last bits of chafe and bran dust off the rice and has different sized screens, which will screen off the broken grains. The process will replace the labor-intensive hand winnowing that the farmers have been doing after the dehulling and partial milling.
