It
is made up of concrete, steel and cement. A pit is dig
in the soil below the ground level about 2 to 2.5 mtrs.
depth. It is covered with a net of 10 mm round steel
duly welded with 5 mm round at a particular distance.We
can put about 50 bags of 100 Kg. weight in this pit at
a time.
There is a controlled mechanical system for opening the
gate of Intake Hopper to Ist Elevator. Ist single Bucket
Elevator lifts the material vertically and feeds it in
Drum Sieve machine. It is a rotary drum type sieving machine
which can separate out the fine dust by aspiration system
developed by -ve pressure and thrash, jute sutli, lumps
etc. will be separated out by sieving.
After sieving through the Drum Sieve, the material will
feed in vibro type Seed Cleaner by gravity. The impurities
which are bigger or smaller than the size of seed, will
be separated out by sieving with the help of different
size sieves and the light impurities will be separated
out by Aspiration System. These light impurities will
be collected in the Dust Cyclone.
After sieving the material from Seed Cleaner, the material
will go into the 2nd single Bucket Elevator by gravity.
This Elevator will lift the material vertically and feed
it in the Worm Conveyor which is fitted on the top of
Ist & 2nd Concrete Bins. The cleaned material will
go into Ist & 2nd Bins. These bins are designed for
multiple hopper from the bottom side. The output flow
of the material can be controlled with variable pocket
feeder and the material can be put in the Worm Conveyor.
The Worm Conveyor takes the material from Ist & 2nd
Bins to feed it to Elevator No. 3 by gravity.
Elevator No. 3 lifts
the material vertically and feeds it to the Gravity Separator
Cum De-stoning machine. In this machine we can separate
out heavy metals, stones, glass pieces and also the light
impurities from the seed. Thereafter, the wheat will go
to scouring machine by gravity. In the scouring machine
dust is removed from the upper layer of wheat by friction.
Dust and some part of bran is separated out from the wheat
by sieving. Aspiration channel is also provided with Scouring
machine for further cleaning of the wheat by -ve pressure
of air stream. From the Scourer Aspiration channel the
wheat goes to Intensive Dampner through Bucket Dampner
by gravity system with the help of Bucket Dampner where
measured quantity of water will be added in the wheat.
Water will be mixed immediately with the help of Intensive
Dampner. From Intensive Dampner wheat will go to single
Bucket Elevator No. E1-4 by gravity.
Elevator No. 4 lifts the material vertically
and feeds it into Worm conveyor No. W3 and feeds the wheat
in Bin No. III, IV, V & VI for conditioning. The wheat
is kept in the conditioning for 16-24 hours depending
upon the variety of wheat and atmospheric temperature.
After conditioning, the wheat is taken out from the multiple
hopper. This wheat is feeded in the Elevator No. E1-5
through Worm Conveyor W4.
Elevator E1-5 lifts the material vertically
and puts it in the second Intensive Dampner through Bucket
Dampner. Desired moisture is added here and the material
is put in Bin No. VII & VIII for about 4 to 6 hours.
Material is taken out from the Bin No. VII & VIII
through the conveyor and is feeded into the Elevator E1-6
by gravity.
Elevator
E1-6 lifts the material vertically and
feeds it into the Scouring/Brush Machine, so that the
bran could be removed from the upper layer of wheat. This
bran is separated by sieving and aspiration channel. Then
this material goes to final Seed cleaner by gravity. The
Seed Cleaner finally performs the cleaning of the seed
and keeps the material in Worm conveyor and then it goes
to Elevator E1-7.
Bucket Elevator E1-7 lifts
the material vertically and feeds it into Milling Bin.
From Milling Bin it goes to Ist break of Roller Mill.
In Roller Mill material is grinded with the help of Chilled
Cast Iron Rolls. After grinding, the material is lifted
vertically by pneumatic conveying system and feeded into
the Plan Sifter through Pneumatic cyclone and air Lock.
In the Plan Sifter we can sieve the material into many
segments. The final product goes to Worm conveyor and
then packing. Intermediate product goes to Purifier machine
for further purification. Desired quantity of Sujji is
taken out for packing and the remaining material goes
to Roller Mill for further grinding and sieving. Coares
material is also goes to further grinding and sieving.
This process is continued in sequence upto desired product.
In the whole process we grind the wheat in grooved rolls
softly, so that purest form of Bran can be obtained. In
this process by separating the bran we can get Samolina,
Sujji in the purest form. In the intermediate product
where we can not separate out the bran from Semoline,
the Semoline obtained at this stage is called Atta.
