Food / Feed
To extend shelf life, most perishable products require drying. The immense variety in composition, viscosity, stickiness, and organoleptic properties, require a high range of dryer capability.
INGETECSA has an impressive range of dryers to choose from to suit every individual process need whether it be drying, cooling, sterilisation, pasteurisation, or roasting. While most of our technologies already dry at low temperatures, INGETECSA also offers vacuum drying under continuous operation or under batch operation. Of paramount importance is always the retention of colour, native functionality and organoleptic properties.
Fruits and vegetables
Several drying technologies from our range are suitable to dry vegetables and fruits. The best technology ultimately depends on the particle size and the functionality that is required. The Spiral Flash Dryer, the Fluidised Bed Dryer or the Andritz-Gouda (vacuum) Drum Dryer each have their own set of benefits. Moisture contents in the range of 80-93% can be dried often in one drying step. Flash drying temperatures don’t exceed 45-48°C. The end product is a flake or a powder, loaded with flavour and beautifully coloured while reconstitution or blending with other ingredients is easy.
Typical vegetables that are processed, are corn, pea, beans, carrot, tomato, pepper, capsicum, pumpkin, squash, (sweet) potato, onion, spinach. Fruits that are successfully dried range from orange, pineapple, berries, apple, pear, banana, mango, kiwi fruit, to various citrus fruits.
Proteins are very much in the spotlights today. Ingetecsa offers several technologies to dry animal and plant based proteins. We have lots references and experience with animal and plant proteins on the Andritz-Gouda Drum Dryer and the Spiral Flash Dryer. Some other drying technologies require a liquid for the drying process. Both the Spiral Flash Dryer as the Drum Dryer work optimally and most economically with the highest dry matter content possible. Drying times are seconds only. In the Spiral Flash Dryer, product temperature stays below 46-47°C. This gentle yet rapid drying sustains the native structure of the proteins, shows excellent solubility and promotes the protein functionalities. On top of this, these two technologies can be placed in a compact building space as opposed to some other technologies that require multiple floors. The homogeneous product quality, minimum loss of activity after re-hydration, the static drying technology and ease of cleaning and inspection, make proteins dried on the Spiral Flash Dryer suitable for pharmaceutic applications.
Over the decades, Ingetecsa dealt with many different fibres and the oldest of our references is probably sugar beet, early 1900. Where not long ago many fibres were seen as a waste product, today they have increasingly become a valuable product with dietary functionality, excellent texturising benefits and nutritional value. The Spiral Flash Dryer or the Andritz-Gouda Drum Dryer are suitable drying technologies for the higher end food applications. The Rotary Drum Dryer fills in the range for animal feed products. The optimum drying technology depends on the final application of the fibre. Ingetecsa can help you making the best selection of drying equipment and conduct tests in their test centre if needed.
Fibres from sugar beet, tapioca (bagasse), corn, barley, wheat, potato, pea, rice bran and rice husk, oat, lentils are a few examples we’ve dealt with before.

Post drying of most dairy products can successfully be done in the static Fluidised Bed Dryer. Depending on the product, particle size, required process and plant layout, Ingetecsa avails of the Fluidised Bed Cooler and the Spiral Flash Cooler. These technologies have proven track records and offer one of the highest uniform and hygienic processing capabilities in the dairy industry.
Drying of dairy sludge can be done after DAF and dewatering step in the Flash Dryer.
Fish proteins and omega-3 acids from the green lipped mussel and krill have unique properties. Delicate processing is required to retain functionality. Ingetecsa has experience with the Spiral Flash Dryer, the vacuum Drum Dryer and the vacuum Paddle Dryer to process these products. Contact us for more information.
