Blanching line

Infeed flume

Carries the product into the line with water and distributes it evenly over the first blancher stage.

Short-high blancher

Compact screw blancher in a short, high design for a fast and intensive blanching step.

Switcher (dry) (2x)

Dry product switch between the blancher stages that distributes the product to the next blancher stage or the bypass.

Long-low blancher (2x)

Screw blancher in a long, low design for an even and precisely controlled blanching time.

Dip flume

Water flume in which the product is briefly immersed between two process steps, for example for a treatment or dosing.

Bypass flume

Bypass flume that allows a process step to be skipped without stopping the line.

Buffer tank

Water tank on the infeed side of the line. Buffers the process water and ensures a constant supply to the flumes and blanchers.

Decelerator

Slows the product down in a controlled way before it enters the line. Prevents damage and ensures an even product flow.

Dewatering shaker

Separates the water from the product at the end of the line by vibration, so the product enters the next process step dry.

Platforms and catwalks

Stainless steel platforms, stairs and walkways for safe access to the blanchers and flumes.

Support frames

Stainless steel support structure on which the blanchers, flumes and platforms are built.

Blanching: the step that determines quality, colour and shelf life

Blanching is a short, controlled heat treatment in hot water. It deactivates enzymes that affect colour, taste and texture and washes excess sugars and starch out of the product. As a result, the product colours evenly after frying and its quality is preserved during freezing and storage.

A blanching line brings that step together in one continuous process. The product is fed in via flumes, passes through one or more blanchers and is then cooled and discharged to the next process step. Each line is designed to suit your product, capacity and layout.

The blancher

Screw blancher: precision in every rotation

Screw blanchers are our speciality: robustly built, accurate and cost-efficient. For every capacity, from compact applications to production lines with very high throughput.

  • No product guide plate: less product damage and fewer stoppages
  • Improved bearings: smoother running and less wear
  • Better sealing: longer service life, less maintenance
First blanching step

Short-high blancher: deactivating enzymes quickly

A short dwell time, a higher temperature and a controlled cross-flow of water. Enzymes are deactivated quickly and evenly. The ideal first step in French fry production.

Second blanching step

Long-low blancher: washing out sugars in a controlled way

A longer dwell time, a lower temperature and an axial water flow wash out reducing sugars efficiently. The result is an even, golden colour after frying.

Cooling and conveying

Counterflow cooler and flumes

Water in counterflow cools the product quickly. A heat exchanger keeps water consumption low. Flumes, as a U-channel or round pipe, carry the product to the next step in a controlled water flow. Bypass valves provide flexible rerouting.
