Your challenge, our solution
Uniform thermal treatment, consistent quality every time
DTS auger blanchers are the benchmark in the potato processing industry, thanks to their high-quality construction and cost-efficient design. Blanching is a crucial step in the production of french fries and other potato products. It inactivates enzymes, leaches out excess sugars and ensures even gelatinisation of the starch. The result: an even colour after frying, a better texture, lower oil uptake and a lower acrylamide content.
- Product quality: short-high blanchers use high temperatures and short retention times for enzyme inactivation, while long-low blanchers use lower temperatures and longer retention times to leach out sugars
- Energy: insulated body and lids, heating by direct steam injection or a shell and tube heat exchanger
- Hygiene: hygienic stainless steel design, with clean-in-place as an option
- Reliability: robust precision construction, built for continuous processes
The process
From washing to cooking, every step in one hand
We supply individual machines and complete systems, including infeed, outfeed and bypass flumes, heat exchanger, controls, service platforms and piping. The process steps where DTS supports you:
Washing
Washing augers that wash and elevate the product in one machine, suitable for unpeeled or peeled potatoes.
Brine / clay bath
Separation by specific gravity, to remove floating foreign material and glassy potatoes from the process.
Blanching
Auger blanchers in every capacity and for every application: from short-time high-temperature and long-time low-temperature blanchers for french fries lines to blanchers for flake lines and fresh potato products.
Cooling
Counter-flow coolers, cooled by heat exchanger or fresh water, available with outfeed by ferris wheel, discharge auger, pump outlet or free float.
Cooking and mashing
Auger cookers with multi-zone direct steam injection, optionally combined with a ricer or mash pump for flake and granule lines.
Auger conveyors
Horizontal, vertical or inclined, with lids, clean-in-place, insulated double-walled housing or load cells.
Buffering and metering
Buffer and metering augers and bin systems for an even supply to the next process step.
Water and by-products
Rotary filters, flumes and waste augers to filter process water and remove by-products.

Line advice
Curious what your blancher or cooler could still gain?
Discuss capacity, energy use or product quality with a DTS specialist. Together we look at where your line is losing out and which change will deliver the most.
DTS at a glance
Specialist in auger-based thermal processing
Potato processors work with tight margins and a raw material that varies from batch to batch. That is why we look beyond the price of a machine, at cost and yield over its entire lifetime.
30+
Years of experience
For more than thirty years we have been designing and building machines and complete systems for the food industry.
S to XL
Any capacity
From compact machines to the largest processing capacities in the world, standard or fully customised.
1 roof
Engineering and build
Design, production and testing all happen at our site in Beusichem, so we stay in control of quality and lead time.
FAT
Tested before delivery
We assemble your system in our own hall and wet-test it, which shortens start-up at your plant.
Complete lines
Need more than blanching and conveying? Together we build the whole line
If your project calls for a complete potato line, DTS works together with the other specialists within the Sticomax Group, machine builders from Belgium and the Netherlands. Together we deliver a line that runs as one, with a single point of contact from engineering to service. These are the specialists we work with on your potato line.
Stumaco
Pre-processing: reception, dry cleaning, destoning, washing and steam peeling.
FoodeQ
Vibratory conveyors for transport, dewatering, grading and dosing, plus thermal processing.
Romonta
Connects the process steps with conveying, service platforms and custom handling.
ICS Spiral Freezers
Spiral freezers for frozen fries and potato specialities.
IntOCon
Stainless steel handling and internal transport up to packaging.
ViwateQ
Surface treatment of stainless steel, so starch and dirt adhere less.
Frequently asked questions
What potato processors often ask us
Yes. We regularly build for existing plants. We map the available space, connections and capacity, and supply the blancher with matching infeed, outfeed, bypass and service platforms.
The short-high blancher works at high temperature with cross-flow water circulation and focuses on fast enzyme inactivation. The long-low blancher works at low temperature and is designed to leach out reducing sugars efficiently, which benefits the colour of french fries.
By direct steam injection or through a shell and tube heat exchanger. The best option depends on your energy supply, your product and the control accuracy you need.
Yes. Our spacious hall lets us assemble your system and wet-test it before delivery. If you cannot attend in person, you can follow the test remotely with 360-degree video.
Yes. Our parts and service team supplies original parts and supports your maintenance team, so your machines stay fit for continuous operation.
