Wheat cleaning process section(1) In the raw wheat cleaning process, the destoner adopts density
classification stone removal machine.The material on the sieve can
be processed separately depending on the quality and flow rate. If
it contains a large number of whole wheat ears, shriveled wheat,
insect-eaten wheat,imperfect grains and other inferior wheat, it
will go to a powerful wheat scouter machine alone for beating,then
air selected.The lower layer material of destoner is heavy wheat
which can be directly put into the scouter machine for slight
beating. (2) According to the quality of raw wheat,we can decide to
use the selection machine or not, and to select all or part. (3)
Add water twice before moistening the wheat,first wash the wheat,
then use computer to automatically control the water machine,which
can assure the water landing precision is high and uniform. (4)
Magnetic separators are installed before wheat scouter machine and
before the pure wheat entering the milling machine to ensure the
striking effect and protect equipment. (5) There are wheat blenders
under both raw wheat silo and wet wheat silo, which can be used to
match different varieties of wheat with crude wheat or pure wheat.
(6) The automation degree is high, and the production process is
monitored by general control room. (7) The wheat cleaning section
is equipped with brushing and air suction treatment before entering
the wheat cleaning cabinet, and the light and small impurities such
as wheat wool and bark are greatly reduced to ensure the purity of
milled wheat. (8) With spraying water process,it can effectively
adjust the moisture of wheat epidermis before grinding and enhance
the toughness of the wheat epidermis. (9) According to the moisture
and impurities of wheat, the wheat washing machine can be adopted
to use or only use the automatic watering machine. (10) The
de-stones are all with separate air nets, which can effectively
ensure the stone removal effect,which facilitate the operation.
(11) Both raw wheat and clean wheat cleaning sections are all with
separate dust removing air nets, which can effectively ensure that
each machine works under negative pressure to prevent dust from
flying.
Wheat milling process section
(1)This project is grade flour production line,which system is
relatively perfect with several grading, which is suitable for
processing soft and hard wheat. (2)The skin grinding system is
equipped with more grading machines to get more wheat core and
wheat residues, and the big bran flakes after 3B will be beat,
which reduces the load of 4B mill machine; Bran and fine bran are
brushed to ensure that the bran is clean. (3)With 5 passes of
powder cleaning system,re-cleaning the wheat core extracted by the
slag mill system,the materials entering the former core mill is
with high purity. (4)In addition to the skin grinding system,all
other systems use smooth roller grinding to ensure light grinding
and grading, reduce the breakage of fine bran flakes as much as
possible, and reduce the content of bran in the flour.The core
grinding system has many passes and graders with slight grinding
which can effectively avoid high temperature to affect the quality
of flour. (5)Due to adopting many sets of bran beating and brushing
machines, the bran flour is with high quality and big quantity,it
can be processed by a whole flat screen bin to improve the flour
yield. If it is mixed with other materials for screening, the
screening efficiency will be low. (6)Regarding the air suction
powder,due to its complex composition, fine particle size, high
viscosity and poor fluidity, it is difficult to sieve if processed
by a whole flat screen bin but the fluidity can be improved if
mixed with other materials which makes sieving easier. (7)The core
grinding system adopts the method of sieving first,then
grading,which makes the material has good fluidity and greatly
improves the efficiency. The process design is more reasonable, the
actual production output is basically stable at about 106t-110t,
and the power consumption per ton of powder in the entire workshop
is about 67 kWh.
