The invention discloses a production technology of
whole wheat flour by using a stone mill. The production technology is characterized in that wheat grains are fed by a feeding hopper, and are conveyed to an air separator through an oblique shaftless
screw conveyor and impurities like shells and
straw are removed, then the wheat grains enter a cylinder cleaning
sieve for cleaning, the cleaned wheat grains are mixed with water uniformly through a dampening
auger, and then a mixture is conveyed a stock bin for wheat
wetting temporary storage; and the wetted wheat grains are conveyed to a wheat brushing
machine for wheat brushing treatment, then the wheat grains after the wheat brushing treatment are conveyed to a steel flour mill for precrushing treatment twice, then the wheat grains after the precrushing treatment are conveyed into a
cyclone unloader and are unloaded to a first minor sifter for classification sifting, a part of front extraction
powder is obtained, the rest material is conveyed to the stone mill to be further milled, the material milled by the stone mill is unloaded to a second minor sifter through the
cyclone unloader for sifting, and finished
whole wheat flour is obtained. The production technology has the advantages that the advantages of a large flour milling technology and the existing stone mill milling technology are integrated, the material is conveyed by pneumatic conveying and the oblique shaftless
screw conveyor throughout, the production technology is flexible, the structure is simple, and the design is reasonable.
