Tomato Powder Processing Plants

It differs from a tomato paste line, which stops at a thick concentrate, by adding a dryer, a powder-handling section and a moisture-proof packing area. The first decision is the route to powder: concentrate followed by spray drying, drum or vacuum drying of a puree, or drying prepared slices and milling them. That choice sets how fully skins and seeds are removed, the concentrate the dryer is fed, whether a carrier is added and how the line is cleaned between runs. The powder specification settles the rest: colour, particle size, residual moisture, flavour and pack format. Tomatoes also arrive in a short season, so a buyer should work out how many months the dryer will run and whether the evaporator should also make paste outside the powder campaign.

Tomatoes are washed, crushed and heated in a hot break so that enzymes do not thin the pulp, then passed through a pulper-finisher that holds back skins and seeds. The puree is concentrated in an evaporator before drying, because the first water costs less energy to remove there than in a dryer. Three dryer families turn the concentrate into powder. A spray dryer atomises it into hot air and runs continuously. A drum dryer spreads it as a film on a heated drum and scrapes off flakes that are then milled. A vacuum plate dryer works in batches at a lower temperature and is the simplest to operate. A fourth route skips the puree: sliced tomato is dried in hot air, then ground and sieved. The difficulty common to every route is composition. Tomato solids are mostly sugars and organic acids, which soften and turn sticky when warm and pull moisture from the air, so wall deposits, lumps and caking in storage are the usual faults. A carrier such as maltodextrin, gentle drying and a dehumidified packing room are the usual answers. The drying method also changes how much red pigment survives, so colour targets should be set before the dryer is chosen.

Typical Process Route

1

Receiving and Washing

Tomatoes are weighed, unloaded and washed to remove soil, leaves and field heat. Fruit left waiting in the sun or stacked deep in crates softens and loses colour, so the unloading rate and the buffer ahead of the crusher need planning.

2

Sorting

Rotten, green, mouldy and split fruit is taken off a sorting belt. A few bad tomatoes darken a whole batch, which shows later as dull, brownish powder.

3

Crushing and Hot Break

The fruit is crushed and heated quickly. This inactivates the enzymes that would otherwise thin the pulp and dull the colour, and it softens the skins for the next step.

4

Pulping and Refining

A pulper-finisher separates puree from skins and seeds through screens of a chosen mesh. A finer screen gives a smoother feed for an atomiser but leaves more fruit in the waste.

5

Concentration

An evaporator, usually under vacuum to protect colour and flavour, raises the solids so the dryer has much less water to remove. The solids it reaches must match what the dryer can handle, because a feed that is too thick will not atomise or spread evenly.

6

Drying

The concentrate is dried by spraying, on a heated drum or under vacuum. The key controls are product temperature, time in the dryer and the carrier, because overheated tomato browns and sticky tomato coats the dryer wall.

7

Milling and Sieving

Flakes from a drum or vacuum dryer are milled, and every powder is sieved to the particle size wanted. Oversize pieces return to the mill, and fines caught in the cyclone and filter are blended back.

8

Cooling and Packing

Powder is cooled before it is packed, because warm powder sweats inside the bag. Packing happens in a dehumidified room into moisture-barrier packs, since dry tomato powder takes up water from the air within minutes of exposure.

Plant Output

Tomato powderMilled drum-dried or vacuum-dried tomato flakes, where that route is chosenSkins and seeds for animal feed or compostFine powder recovered from the cyclone and filter

Applications

  • Instant tomato soup and sauce mixes
  • Seasoning blends for snacks, crisps and noodles
  • Tomato flavour and colour in bouillon and stock cubes
  • Dry cooking bases for stews and rice dishes
  • Pizza, pasta and ready-meal seasonings
  • Reconstituted paste for kitchens without cold storage
  • Natural red colour in dry food blends

Key Features

  • Concentrate Before Drying

    An evaporator ahead of the dryer removes the early water cheaply, so the dryer is smaller and uses less fuel for each kilogram of powder.

  • Dryer Matched to Sticky Solids

    Spray, drum and vacuum dryers cope with tomato sugars differently. The choice sets batch or continuous running, the carrier needed and how much deposit builds up.

  • Colour and Pigment Protection

    Short heat exposure, a quick run from fruit to dryer and a sound hot break keep the red colour. Set the colour target before choosing the drying route.

  • Moisture-Proof Finishing

    Cooling, a dehumidified packing room and barrier packaging keep the powder from picking up water and caking.

  • Dust and Fines Control

    Cyclones, bag filters and extraction at milling and packing points recover fine powder and keep airborne dust down, since dry organic powder can burn.

  • Front End Shared With Paste

    Washing, hot break, pulping and evaporation are the same as on a paste line, so one front end can often serve both products.

Frequently Asked Questions

What information is needed to size Tomato Powder Processing Plants?
Start with fresh tomato throughput per hour and the number of weeks the season runs, then the powder wanted: particle size, residual moisture, colour and pack format. These fix how much water the evaporator and dryer must remove, which is the largest item in the plant. Also say whether a carrier is acceptable on the ingredient list, which fuel the site has for heating the drying air, and whether the evaporator must also make paste outside the powder campaign.
What capacity range does Tomato Powder Processing Plants cover?
The indicative capacity range is 500–10,000 kg fresh tomato/hour. It is stated on a fresh tomato basis per hour, so restate your own volume on that basis and say how many hours a day the plant will run.
Spray, drum or vacuum plate: which dryer suits tomato?
A spray dryer runs continuously and gives a fine, even powder from concentrate, but it needs a carrier and careful wall-temperature control because of the sticky sugars. A drum dryer is simpler and copes with a thicker feed, though the product sees more heat and leaves as flakes that need milling. A vacuum plate dryer is easy to run and gentle on colour, but it works in batches. Volume, product value and operator skills decide. The continuous option is described under spray dryer.
Why does tomato powder cake or clump, and how is it prevented?
Tomato solids are mainly small sugars and organic acids. In the dry, amorphous state they soften at a fairly low temperature and absorb water from the air, so the powder turns sticky. Prevent it with a carrier at drying, a final moisture low enough for the pack, cooling before filling, a dehumidified packing room and vapour-proof packaging. A powder kept in a humid store in the wet season will cake whatever the dryer did.
Does the drying method change the colour of tomato powder?
Yes, because the method decides how much lycopene, the red pigment, survives. In comparisons of drying methods on tomato, freeze-dried samples kept the most, with sun-dried next. Freeze drying costs far more for each kilogram, so most plants use spray, drum or vacuum drying and protect colour with short heat exposure, a quick run from fruit to dryer and a sound hot break. Agree the colour target with your buyer before choosing the dryer.
Is a carrier such as maltodextrin needed?
Often, for spray drying. Without one, sugar-rich tomato concentrate sticks to the chamber wall and the powder clumps. A carrier raises the temperature at which the solids soften, so particles stay free-flowing, but it dilutes the tomato content and appears on the ingredient list. Drum and vacuum routes tolerate pure tomato better, at the cost of more heat on the product. Decide with your buyer whether a pure powder or a carrier-added one is acceptable.
Can one plant make both tomato paste and tomato powder?
Washing, hot break, pulping and evaporation are the same for both, so one front end can feed a paste filling line or a dryer. The back ends differ: paste is filled hot or aseptically, while powder needs a dryer, a mill and a dehumidified pack room. Running both lets the evaporator work outside the powder campaign, but each product needs its own finishing equipment. Compare tomato paste processing plants.
