Grasim Industries (Century Rayon)Food manufacturers, seasoning companies, QSR chains and exporters all buy dehydrated onion, and an onion dehydration plant consultant helps you decide how to supply them. The plant turns white onions into flakes, kibbled pieces, granules and powder, and some units add onion paste lines. Entrepreneurs choose it because India has surplus onion seasons and steady demand from processed food makers. NPCS prepares the project report, technology comparison and approvals roadmap so you can plan with clear numbers.

Market Demand for Onion Dehydration in India
Dehydrated onion sells where food is made at scale, and demand follows processed food growth, export orders and the surplus seasons when fresh onion is cheap. Mahuva in Gujarat is the main dehydration hub, with Nashik and Madhya Pradesh also active. Export potential is high, though buyers set their own specifications.
- Snack seasoning and spice blend makers
- Ready meal and soup manufacturers
- QSR chains buying consistent flakes and powder
- Exporters serving overseas food companies
Dehydrated Onion Products You Can Make
Most new units start with flakes, chopped and minced grades, then add granules and powder as buyers ask for them. Fried onion and onion paste suit a different customer, usually ready meal and QSR kitchens, and they follow their own tax entries in the project financials.
- Dehydrated onion flakes, chopped, minced, granules, powder
- Fried onion
- Onion paste
Onion Dehydration Plant Process
The onion dehydration plant process moves fresh onions through grading, peeling, washing and slicing before staged drying on belts. Drying is where most of your energy cost and colour quality is decided. Multi-stage belt dryers suit steady volume, tray dryers suit smaller starts, and heat-pump drying helps retain colour. After drying, the product is milled, sieved and sorted by colour and metal. Quality checks cover moisture, colour, pungency, microbial load and foreign matter, measured against each buyer's or export specification.
- Receiving and grading
- Peeling and topping
- Washing
- Slicing
- Belt drying in stages
- Milling and sieving
- Sorting (colour, metal)
- Packing
Raw Materials and Machinery for an Onion Dehydration Plant
White onion varieties suited to dehydration are the main input, along with laminated bags and cartons for packing. Sourcing usually centres on Mahuva and Bhavnagar in Gujarat, Nashik in Maharashtra, Madhya Pradesh and Karnataka. The machines that matter most are the multi-stage belt dryer, its burners or heat exchangers, the colour sorter and the metal detector.
- Peeler
- Washer
- Slicer
- Multi-stage belt dryer
- Burners or heat exchangers
- Mill
- Sifter
- Colour sorter
- Metal detector
- Packing
Onion Dehydration Plant Licence and Approvals
Start with business registration, then apply for consent to establish from the State Pollution Control Board before construction. Food processing is Green below 10 KLD wastewater without a boiler, and Orange with a boiler or at 10 KLD and above. After that, plan these before commercial production:
- FSSAI licence
- Factory licence
- APEDA RCMC for exports
- Legal Metrology for retail packs
- Consent to operate
| Pollution category | Food processing: Green below 10 KLD wastewater without boiler (CPCB S.No. 56.2); Orange with boiler or 10 KLD+ (56.1) |
|---|---|
| HSN code | 0712 20 (dried onions) |
| GST | 5% on dried onions not otherwise prepared; paste and fried onion follow their own entries, applied in the project financials |
| BIS / quality control order | No QCO |
| FSSAI | FSSAI licence |
| Other licences | APEDA RCMC; factory licence; Legal Metrology for retail packs |
Choosing the Right Onion Dehydration Technology
Multi-stage belt dryers suit plants that run at higher volumes, since they dry continuously and keep product quality even. Tray dryers cost less to start with and fit smaller capacities, but they need more handling and labour. Heat-pump drying is worth considering if colour retention matters to your buyers. Because drying energy is a major running cost, NPCS compares the options against your capacity, fuel availability and target customers before you commit to machinery.
Managing Seasonality and Working Capital
The main onion harvest runs from February to May, so stocking is part of the plan. You'll need enough working capital to buy fresh onions in season and keep the plant running afterwards. The investment range excludes seasonal working capital, so it must be budgeted separately. In practice, onion price swings make a clear buying and stocking plan as important as the machinery you choose.
Government Schemes and Project Finance for Onion Dehydration
Schemes relevant to this project include Operation Greens, where onion is a TOP crop, along with PMKSY, PMFME and the Agriculture Infrastructure Fund. Eligibility depends on your unit and the lender. NPCS reports are used for bank loans and government programmes, subject to each lender's requirements, and a bankable onion dehydration plant project report gives the lender clear costs and projections.
What Decides Success in an Onion Dehydration Plant
Good operators choose onion varieties with high solids, control drying energy cost and hold the certifications export buyers ask for. The risks are just as clear.
- Onion price volatility
- Rising energy cost
- Export restrictions in shortage years
- Selling peels and tops as compost or feed to recover value

Onion Dehydration Plant: Frequently Asked Questions
How much does it cost to set up an onion dehydration plant?
An indicative investment is about ₹3–25 crore for 10–100 TPD of fresh onion. This excludes land and seasonal working capital. Your onion dehydration plant setup cost in India depends on capacity, dryer type and location, which the project report works out.
Which pollution category applies to an onion dehydration plant?
Food processing is Green below 10 KLD wastewater without a boiler (CPCB S.No. 56.2). It is Orange with a boiler or at 10 KLD and above (56.1). Your drying fuel and wastewater volume decide the category.
How much land and power does an onion dehydration plant need?
A plant typically needs about 1–5 acres and a power load of about 200 kW–1 MW, depending on capacity. Water requirement is moderate. These are indicative figures, and your layout and chosen dryer will refine them.
How do I start an onion dehydration plant?
Fix your capacity and target buyers, then choose the drying technology and location near onion supply. Register the business and obtain consent to establish and the FSSAI licence. A detailed project report ties these steps to costs and finance.
