Industrial Food Dryers and Complete Drying Lines, Built Around Your Product
From a single machine to a full line: we design and supply five industrial food drying machines and 24 complete drying lines – chili, onion, garlic, mango, banana, mixed vegetables, mushrooms, fish, jerky, cassava, tomato, dates, coffee and cocoa, herbs and spices – each with washing, cutting, drying, milling and packing matched to the throughput of the dryer.
An industrial food dryer is chosen from three numbers: the water to remove per hour, the highest temperature your product tolerates, and your local energy price. Tonde Machinery builds five machine families to cover that range – a continuous mesh belt dryer for 500-3,000+ kg/h lines, a batch heat pump drying room that cuts electricity use 60-75% while protecting colour and aroma, a hot air circulation tray oven for affordable batch drying from 48 trays, a vacuum freeze dryer for premium products, and a microwave tunnel that dries and pasteurises in minutes. If you need more than a machine, 24 complete line designs pair that dryer with washing, peeling, cutting, blanching, dewatering, milling and packing sized to the same throughput. Send us your material and target capacity and you receive a machine configuration, layout drawing and cycle-time estimate within one working day.
24 Drying Lines, Each Engineered Around One Material
A dryer is only one machine in a line. Every line below specifies the washing, cutting, blanching and dewatering ahead of the dryer, the drying curve itself, and the cooling, milling or packing that follows – with throughput tiers, utility consumption, floor space, labour per shift, investment range and payback worked out for that material.

Buying the dryer from one supplier and the rest of the line from three others is where projects slip: mismatched throughput, three commissioning visits and no single party answerable for output. We build all three sections and balance them to one number – see how the lines are put together →
Pre-Treatment
Bubble and vortex washing, brush washer-peelers for roots, cutting and dicing, blanching, then centrifugal or air dewatering. Mechanical dewatering alone removes 10-20% of the water the dryer would otherwise pay to evaporate.
Drying
The core section: continuous mesh belt, batch heat pump room or hot air tray oven, sized from a drying test on your own material so cycle time, colour and energy use are quoted as numbers, not estimates.
Post-Treatment
Cooling, moisture conditioning, grading, hammer milling to 20-100 mesh powder, metal detection and barrier packing with nitrogen option. Milling alone lifts order value 30-50% on the same material.
One supplier, one contract, one commissioning team and one spares catalogue that covers every machine in the line. Wear parts are listed in the handover pack so your maintenance team orders against a single reference list.

Vegetables, Fruit, Spices, Roots, Mushrooms, Fish, Meat and Herbs
A dryer only performs if it matches the material. These are the product groups we size machines for most often, with typical temperature and moisture targets – click through for the full line.
Vegetables
Onion, carrot, cabbage, pepper, green beans – 55-80℃ to 6-10% moisture.
Fruit
Mango, banana, apple, papaya, pineapple – 45-65℃ to 15-20% moisture.
Chili & spices
Whole pods and flakes – staged recipes that keep the red colour.
Roots & tubers
Cassava, sweet potato, potato chips for flour and snacks.
Mushrooms
Whole and sliced mushrooms – 50-65℃, aroma retained.
Fish & seafood
Salted fish, shrimp, squid – 45-60℃, monsoon-proof production.

Four Reasons Buyers Stay With Tonde Machinery
Custom-built to your material
Chamber size, belt layers, airflow and heating source are configured to your raw material, initial moisture and target capacity – not sold off a shelf.
Energy cost you can calculate
We quote kWh per kg of water removed and expected cycle times, so you compare machines on real operating cost instead of brochure percentages.
Test drying before you commit
Send 2-5 kg of your material. You get back the drying curve, colour photos, shrinkage and moisture data, and a machine sized from those numbers.
Delivered and commissioned worldwide
Machines ship in standard containers with manuals, wiring diagrams and remote video commissioning by the engineers who built them.

What Buyers Say After Commissioning
Feedback from processors running our dryers on fish, chili, fruit, herbs, vegetables and snacks.
“We replaced open sun drying with a heat pump room and now dry salted fish through the rainy season. Output is consistent at 11% moisture and the colour no longer varies from batch to batch. Energy bills came in roughly two thirds lower than our old electric oven.”
Lagos, Nigeria
“The continuous belt line runs chili at about 1.2 t per hour and the red colour is graded A consistently. What convinced us was the test drying: they ran our own pods first and sent the drying curve before we paid anything.”
Kochi, India
“Two heat pump rooms were delivered on schedule and commissioned over video call. Our team had no prior experience with this type of dryer, but the manuals and the remote session were enough to start production in the same week.”
Surabaya, Indonesia
“We bought a hot air circulation oven as our first industrial dryer. Two years on it still runs every day. When we expanded, the same engineers sized the belt line to match the oven’s output, so both machines now feed one packing line.”
Bogotá, Colombia
“Honeysuckle and chamomile are delicate – too much heat and the petals brown. Their engineers set a 45℃ profile and the dried flowers keep their pale colour, which is exactly what our European buyers ask for.”
Cairo, Egypt
“The microwave tunnel cut our drying time from hours to minutes and pasteurises in the same pass. Microbiological counts dropped and we stopped losing product to mould during humid weeks.”
Hanoi, Vietnam

Frequently Asked Questions
What is the smallest machine you supply?
For industrial production, the hot air circulation tray oven with 48 trays is the standard entry point – it suits pilot runs, small factories and high-value products. Continuous belt lines start around 500 kg per hour.
Do you supply only the dryer, or a complete drying line?
Both. Many buyers start with a single dryer and add equipment later. If you want the whole line, we supply pre-treatment (washing, peeling, cutting, blanching, dewatering), the drying section and post-treatment (cooling, conditioning, milling, metal detection, packing) under one contract, and the wet end is matched to the dryer’s actual throughput.
How much does a complete drying line cost?
Equipment alone typically runs USD 4,000-25,000 for a single entry-level machine, USD 40,000-200,000 for a continuous line, and USD 150,000-350,000 for a full dehydration plant handling 2-5 t of fresh material per day. What most budgets miss: machinery is usually only part of a landed project – the rest is freight, customs clearance, civil works, utilities, installation, commissioning and training. We quote both figures separately so you can plan cash flow.
How do I know which drying technology fits my product?
It comes down to three things: how much water has to be removed per hour, how sensitive the product is to heat, and what energy costs locally. Heat pumps win on running cost and colour, tray ovens on purchase price, belt dryers on throughput, and microwave or freeze drying on premium quality.
Can you dry my material before I buy a machine?
Yes. Send 2-5 kg of product and we run a drying test, then return the drying curve, colour photographs, shrinkage and moisture figures together with a machine sized from those results.
Which heating source should I choose?
Steam where a boiler already exists, gas where it is cheap, electricity where simplicity matters, and an air-source heat pump where electricity powers the line and running cost is the deciding factor. We quote all options against your local energy prices.
Can I add washing or packing equipment to a dryer I already own?
Yes, and it is often the cheapest upgrade available. We size the washing, cutting, dewatering or packing section to the throughput of your existing dryer, so the line balances without replacing the machine you have already paid for.
Do you ship and install overseas?
Yes. Machines are built to ship in standard containers, and every shipment includes installation manuals, wiring diagrams, a spares kit and remote video commissioning with our engineers.
What warranty and after-sales support do you provide?
A 12-month warranty on major components, a consumable spares kit with every machine, and lifetime remote technical support from the engineers who built your dryer.
