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.
