"Shuangfu" series of complete sets of equipment adoptexcellent clearing equipment and the flour processing technology of "grinding and sieving according to different grades,loosening by way of bump,highly efficient quadrate sieve and air current refining".Characteristics of the equipment are as follows:
I. The whole equipmentis laid in plane. The equipment is economical in investment,compact in structure,simple in opoeration,easy in maintenance and more improved in stability.
II.The equipment has high-quality energy-saving electric motor,and its power consumption is lower than that of any other similar product in the country. 
III.The efficient new type quadrate sieve increases the in-sieve swing and promotes the material flow.
IV.Air current refining fastens the material transmitting,thus the temperature of the flour is kept low and the flour quality is guaranteed.
