Dryhaul

A truck-borne drying unit that turns orchards' rejected fruit into stock

Rural

TL;DR Dryhaul is a food-drying line built into a container, and it moves by truck from one fruit belt to the next as the harvests change. It buys or processes the fruit that sorting throws out, dries it into slices or powder and sells it in bulk to food makers. FPOs supply the fruit and ingredient buyers pay.

The problem

A lot of the fruit sorted out on the farm simply gets lost. The national post-harvest loss study found sorting and grading at the farm among the biggest loss steps - 4.58% for guava, 2.74% for mango and 3.1% for tomato[1]. Total fruit losses ran from 6.02% to 15.05% depending on the crop[1].

Processing near the farm would save some of it, but the numbers are awkward. A small dryer beside one orchard runs for a few weeks a year. A big plant in town is too far away for cheap rejects to travel to. The same study asked for more farm-level dryers and dehydration units[1], so everyone knows about the gap and nobody has filled it.

The idea

What it does, in regulatory terms: food processing that needs FSSAI registration or a licence. The operator holds it, not the farmer, and answers for hygiene, testing and labels[4]. FSSAI's published licence types don't obviously cover a factory that moves every month, so settle the route with your state's food safety office before you build anything.

The unit is a shipping container fitted with a washer, slicer, blancher and a hybrid dryer that runs on solar heat with electric backup. It parks at an FPO's collection centre for two to six weeks and processes culls and surplus on site, and then it moves on to the next crop - mango in summer, guava in winter, tomato or onion in between. Dried slices and powders go out in bulk bags to food makers.

I reframed the seed, which pitched processing units rented out to farmers. Food sold to buyers needs a licensed operator, quality control and an offtake contract, and very few smallholders can carry all three. So Dryhaul runs the unit itself. It either buys the fruit outright or charges the FPO a per-kg processing fee.

Who pays

The main payer is the ingredient buyer. Think makers of snacks, ready meals, bakery fillings and spice mixes who buy dried fruit and vegetable powders. One farm-processing startup supplies food companies including large caterers and IRCTC, which tells you the demand is real[2]. The second payer is the FPO, which either sells culls to Dryhaul or pays a toll fee per kg and sells the output itself. What do culls and toll fees go for? Nobody publishes it, so test it.

Why now

The 2022 loss study put total post-harvest losses at ₹1,52,790.42 crore and called for farm-level dryers[1]. Solar and hybrid dryers are now sold commercially in India, from phase-change cooling firms among others[3]. And most fruit belts now have FPOs. SFAC alone listed 3,711 under the 10,000 FPO scheme in February 2025[5], so there's someone to sign with at every stop.

Market signal

I couldn't find a verifiable public figure for India's dried fruit and vegetable ingredient market. The closest signal is that farm-processing startup, which reports 1,100+ customers and 12,000 grower farmers for farm-processed ingredients[2], and those are company claims. Adjacent - fruit makes up 19.34% of the ₹1,52,790.42 crore post-harvest loss[1], which is context and not your market.

Who's already doing this

That startup buys through village collection centres and processes in fixed micro-units run by women entrepreneurs[2]. A phase-change cooling firm sells solar dryers and solar cold rooms as equipment[3], and a solar cold-room maker sells rooms that keep produce fresh rather than processing it[6]. All of them stay put. Nobody I found moves a licensed drying line between crop belts to keep it busy all year.

How hard is it?

Difficulty Hard (54/100)
Starting capital ₹1.28–2.44 Cr
Time to launch 9–12 months

You're building food-grade hardware, running a licensed food business and doing logistics, all at the same time. The line has to hit the same moisture and microbial specs at every stop even though the water and power change. Every move costs time and money, so each stop needs enough fruit to justify the trip, and buyers will want steady grades before they sign volume contracts.

Licences and approvals

Yes. This is a food business, so you need food safety approval before you sell a single bag.

  • FSSAI registration or licence, based on turnover and type of business, before you sell any output[4]. Ask the state food safety office in writing how a unit that keeps changing location should register, before you build.
  • FSSAI packaging, labelling and contaminant standards for dried products, before the first sale. Test every batch.
  • Vehicle registration and road rules with the RTO, before fabrication, since a container on a truck has size and weight limits.
  • Company registration, GST and DPDP Act compliance before launch, because you'll hold grower names, phone numbers and payments[7].

Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.

How AI can power this business

  • Route planning. Combine harvest calendars, FPO supply estimates and buyer orders to pick the next stop and how long to stay.
  • Dryer control. Use sensor readings to adjust drying time as solar heat changes through the day, so each batch hits the target moisture with less backup power.
  • Grading culls. A camera on the intake belt can sort incoming fruit by ripeness and damage, which helps you price culls fairly with the FPO.
  • Batch records. Pull moisture, temperature and lab results into one batch file for each buyer and inspector.

Don't let AI sign off on food safety. Moisture and microbial results have to come from proper tests, and a person releases each batch.

Biggest risks

  • Licensing grey area. A food unit that changes address every few weeks may not fit the standard licence, and a delay leaves the truck idle.
  • Thin margins on culls. Rejected fruit is cheap but uneven, and grading, drying and packing could cost more than buyers will pay.
  • Utilisation gaps. If harvests in neighbouring belts overlap or fail then the unit sits around doing nothing.

Our take

This is a good fit for a founder with food-processing and plant experience who doesn't mind trucks and paperwork. It is not for someone hoping to rent out machines and collect fees. Before you build anything mobile, rent a fixed dryer at one FPO and prove a buyer will take the output at a price that covers culls, energy and labour.

Questions founders ask

Plan for roughly ₹1.28–2.44 Cr for the container line, dryer, truck and licensing. Renting a fixed dryer at one FPO first is a much cheaper test.

Do I need a licence to start a fruit drying business in India?

Yes. You need FSSAI registration or a licence, and you must meet its packaging and labelling rules. A unit that moves needs written guidance from the state food safety office.

Can I start a mobile food processing unit in another country?

Yes, wherever fruit belts lose culls and harvests come at different times. Food safety approval for a moving unit will be the first thing to check with your local regulator.
