Corn grist processing with modified mini jet-propelled rice mill

White waxy corn was used to study the corn grist production method using modified mini jet-propelled rice mill. Orthogonal design was used to determine the basic parameters of rice mill and its effects on the quality of corn grist. The optimal pretreatment of corn was performed to obtain the best grist rate, weight per kW.h, and homogeneity of particle size for meeting the processing need of corn grist in rice mill of countryside. The results showed that the basic parameters affecting the processing by equipment were rotational speed, weight of flying-wheel and distance between knife and rotor. The optimal basic parameters were as follows： 1296 rpm of rotational speed, 5 kg of flying-wheel weight, 5 mm distance between knife and rotor. It was found that the basic parameters affecting the processing of waxy corn were initial water content of corn, additional water suppling rate, water temperature and water regulation time. The optimal values recorded were as follows： 12% water content of dry corn, 4% of addtional water, 40℃ of water temperature and 3 rain of waterkeeping time.
