To be incorporated in the production process of a rice whitener, the Low Heat-rise Rice Whitener(LIANGGONG) Model of CFN25F is used for bran removing and whitening of brown rice.

Brown rice entered into the machine from feed hopper .By a screw propeller into milling chamber and move forward spirally along the roll surface. The machine have high-blast pressure and multi-Air Volume blower “enhanced air jetting ” subjected to Inside the milling chamber across hole of hollow–spindles and emery roller,Under the combined function of the emery roll and steel brakes, accompanying the fast rotating emery roll rice come into vortex make rolling rice .bran layer is repeatedly scoured and abraded, ensuring bran removing and rice whitening.

Roller grinds the surface of rice for removing chaff In the process of milling rice. Rice Inside the milling chamber get friction and collision, emerge a group of heat. The surface temperature of rice was elevated. Because of the bad thermal conductibility of rice, Heat convey slow from the surface of rice inside .Rice forming the bigger grads of temperature (even if temperature difference). The bigger of temperature difference provoked heat effect and the heat effect lead to rice’s breaking or cracking because out of rice’s inherent strength. the Low Heat-rise Rice whitener Model of CFN25F’s Air Volume is two or three times of conventional whitener. It’s wind carries off thermal which the ground cut and massive friction produce, increases exhausting chaff, suppresses or reduces temperate of rice to elevate. This brings the “self-whitening” and/or “inter-whitening” actions between the rice grains into full play, resulting in excellent “rice abrading” and “bran brushing” effects, therefore, in clean and glossy rice product with little bran adhered and in low temperature.

The air uses the double re-adjustable counter-pressure device at the outlet, which causes whitening chamber pressure even. This aircraft is equipped with the inflow in the import to install and the air outlet is equipped with inflow cool rice trough .These enhanced the rice hulling machine to use wind efficiency ,thus realizes “dynamic cool rice” ,further reduces rice temperature. As stated above, reduced the rice whitening unit wind net power equipment with power consumption .So it is one kind of energy conservation low temperature rise rice whitener.
