Wheat in at one end, bagged flour out at the other.
Flour milling is the largest food-machinery export line India has, and the range is unusually wide: a single-machine atta chakki for a village market, or a five-floor roller flour mill producing 300 tonnes of maida, sooji, atta and bran every day. We quote both from the same engineering desk.

Scope
Overview
Two entirely different machines called by one name
An atta chakki grinds whole wheat in a single pass and sells on simplicity and low power. A roller flour mill separates the grain into endosperm, semolina and bran across dozens of passages and sells on extraction rate and flour specification. Choosing wrongly is the most expensive mistake a new miller makes.
Atta chakki plants use emery-stone or steel-disc grinding at 900–1,500 rpm, with an aspiration channel to keep flour temperature down and a rotary or vibro sifter to grade the output. They run at roughly 0.06–0.09 kWh per kilogram of flour, need one or two semi-skilled operators, and are the correct choice for wholemeal atta markets in Africa, South Asia and the Middle East where the consumer expects the bran to stay in the flour.
Roller flour mills break the wheat progressively between chilled cast-iron rolls — corrugated break rolls followed by smooth reduction rolls — with purifiers and plansifters between passages. Milling is preceded by a full cleaning house and by conditioning: wheat is dampened to 15.5–16.5% moisture and rested 8–24 hours in tempering bins so the bran peels cleanly. This is what makes 72–78% maida extraction with 0.45–0.55% ash possible.
Cleaning is where most flour quality is won. A standard cleaning house runs a drum or vibro pre-cleaner, a magnetic separator to protect the rolls, an aspiration channel, a gravity destoner, an indented cylinder or disc separator for barley and oats, a scourer or peeler, and increasingly an optical sorter for ergot and dark impurities. We size each unit at 1.5–2× the mill's nominal throughput so cleaning never becomes the bottleneck.
Product handling is quoted to suit your building. Small plants use bucket elevators and gravity spouting; from about 30 TPD upwards we specify low-pressure pneumatic conveying, which costs more in power but keeps the mill dust-controlled and reduces the number of floors required. Bagging can be manual with a scale and stitcher, semi-automatic with a net weigher, or fully automatic with a packing machine at 300–600 bags per hour.

How we work
We source from India's established brands — we do not manufacture
Akarta Exports is a sourcing and export house. We do not own factories and we do not claim to. Our value is that we know which well-known Indian brands and manufacturers make what, to what standard, and at what price — and we buy from them to the exact specification you give us.
01 — Your specification, written down
We start from your specification, not from a catalogue. Grade, dimension, tolerance, finish, test standard, pack, artwork and labelling are put in writing and confirmed with you before a single enquiry goes out.
02 — Matched to the right Indian brand
We place that specification with established, well-known Indian brands and manufacturers in the cluster that genuinely makes the product — Morbi for tiles, Rajkot and Ludhiana for machinery, Meerut and Jalandhar for sports goods, Kerala and Gujarat for spices.
03 — Offers compared on merit
Because we own no plant and owe no factory a minimum offtake, we compare offers openly on quality, consistency, capacity and price — and tell you where a lower price will not hold up in your market.
04 — Inspected, consolidated, shipped
Our own inspectors clear the goods at the brand's plant and again before loading. Multiple brands and multiple divisions consolidate into one container, one invoice and one document set.
Brand names are disclosed to you on the offer and named on the inspection report, so you always know whose production you are buying. Where a buyer already has a preferred Indian brand, we are happy to source that brand and handle only the inspection, consolidation, documentation and shipping.

Technical data
Flour mill plant specifications by capacity
Indicative engineering envelopes. Extraction rate assumes sound milling wheat at 11–13% protein; softer or damaged wheat reduces both extraction and throughput.

Quality assurance
Nothing leaves India until our own inspectors clear it
Akarta runs an in-house quality department with inspectors assigned to each division. Goods are checked at the factory during production and again before loading, against the written specification agreed on your purchase order — not against the factory's own grading.
- Pre-production sample approved by the buyer before bulk manufacture begins
- In-line checks during production for shade, calibration, dimension and moisture
- Pre-shipment inspection with photographic report before container sealing
- Third-party inspection (SGS, Bureau Veritas, Intertek) arranged where required

Buyer questions
What importers usually ask us first
Should we buy an atta chakki plant or a roller flour mill?
It depends entirely on the flour you sell. If your market wants wholemeal atta, a chakki plant costs a fraction as much, uses less power per tonne and needs less skill to run. If you need white maida, sooji or bakery-specification flour with controlled ash, only a roller mill will produce it — the separation simply cannot be done by single-pass grinding.
How much wheat do we need in store to run the mill?
Plan on a minimum of ten to fifteen days of milling capacity in silos or godown, plus tempering bins for 8–24 hours of conditioned wheat. A 100 TPD mill therefore needs roughly 1,000–1,500 tonnes of raw wheat storage and about 60–100 tonnes of tempering capacity.
Can the mill handle maize, millet or pulses as well as wheat?
Yes, with configuration changes. Maize needs a degerminator ahead of milling and a different roll fluting; pulses and besan are usually better served by a dedicated disc mill or pulveriser. Tell us the full product list at enquiry stage and we design the flow for the switch-over rather than retrofitting later.
What is the realistic power consumption?
A well-set roller flour mill consumes about 0.055–0.075 kWh per kilogram of flour including cleaning and conveying. An atta chakki plant runs a little higher per kilogram at 0.06–0.09 kWh, but on a much smaller connected load. We give the connected load and the estimated running load on every quotation so you can size your transformer and generator.
How long does installation take at site?
A mini atta plant is running within a week of the crates opening. A 30–50 TPD roller mill takes three to five weeks of erection followed by one week of trial milling and adjustment; a 200–300 TPD plant takes eight to twelve weeks. Civil work and building readiness, not machinery, is usually the critical path.
