DTS — screw conveying process solutions for blanching, cooking and cooling
DTS is a specialised manufacturer of industrial screw conveying process systems for the food industry, with a strong focus on blanching, cooking and cooling applications. DTS technology is widely used in the processing of potato fries, as well as vegetables and fruit, where controlled thermal treatment, gentle product handling and continuous processing are essential.
DTS systems are engineered to deliver uniform heat transfer, stable product flow and high-capacity operation, making them ideally suited for demanding industrial environments.
Who is DTS?
DTS is an engineering-driven company focused on continuous thermal processing using screw conveying technology. The brand has built a strong reputation in the potato processing industry, particularly for French fries, but also serves processors of vegetables and fruit.
DTS machines are designed to combine robust mechanical construction with precise process control, ensuring reliable operation and consistent product quality.
What does DTS do?
DTS designs and manufactures screw-based process equipment that supports key thermal processing steps, including:
- blanching
- cooking
- cooling
- controlled product transport between process stages
Their solutions are typically integrated into continuous production lines, supporting high throughput while maintaining gentle handling of fragile products.
DTS machines & process systems
1) Screw Blanchers
Screw blanchers are used to thermally treat products prior to freezing, frying or further processing.
Key process benefits
- uniform blanching through controlled residence time
- even heat distribution via water or steam
- gentle handling of products through screw transport
- effective enzyme inactivation
Typical applications
- potato fries
- sliced or diced vegetables
- prepared vegetable products
2) Screw Cookers
Screw cookers provide controlled cooking for products that require precise thermal profiles.
Advantages
- stable cooking temperatures throughout the product mass
- adjustable dwell time via screw speed control
- consistent texture development
- continuous, high-capacity operation
Applications
- potato products
- vegetables and fruit
- ready-to-process ingredients
3) Screw Cooling Systems
Screw cooling systems rapidly reduce product temperature after blanching or cooking.
Process value
- immediate temperature reduction to stabilise product quality
- controlled cooling using water or other cooling media
- gentle transport to prevent product damage
- preparation for downstream freezing or further processing
These systems are critical in maintaining product integrity and food safety.
4) Integrated Blanching, Cooking & Cooling Lines
DTS specialises in complete screw-based processing lines, combining multiple process steps into one coordinated system.
Line characteristics
- integrated blanching, cooking and cooling
- synchronised screw conveyors for smooth product flow
- compact and efficient system layouts
- automation-ready designs
These lines are commonly used in French fries production plants and high-capacity vegetable processing facilities.
How DTS screw conveying technology works
DTS systems operate on the principle of controlled screw transport combined with thermal processing:
- products are conveyed through the system by rotating screws
- residence time is controlled via screw speed and system length
- heat is applied through water, steam or thermal media
- cooling stages stabilise the product before downstream processing
This approach ensures uniform treatment, consistent throughput and minimal mechanical stress on the product.
What is DTS specialised in?
DTS specialises in screw conveying thermal process solutions that deliver:
- consistent blanching, cooking and cooling results
- high-capacity continuous processing
- gentle handling of fries, vegetables and fruit
- stable and predictable residence times
- robust construction for industrial operation
Their technology is particularly well suited for processors of potato fries, vegetables and fruit who require reliable, repeatable thermal processing.
