Blanching machines for vegetables and potatoes
Even blanching means: every piece for the same time at the same temperature. Our screw blancher keeps the residence time constant via the rotational speed and is a core component of the French fries line.

Blanching: our designs
Every design is engineered for your raw product, its degree of soiling and your target capacity.
Screw blancher
Defined residence time via the screw speed, resulting in very consistent blanching quality.
Horizontal blancher
Horizontal design for high throughputs with low overall height.
Drum blancher
Rotating drum for gentle circulation of delicate products.
Design
What matters when sizing the machine.
This is the information we need to recommend the right design and size for you.
-
01
Purpose
Inactivating enzymes, leaching out sugars or preparing the texture: the purpose determines temperature and time.
-
02
Residence time
It must be the same for every piece. In the screw blancher it is set via the screw speed.
-
03
Sensitivity
Delicate produce needs gentle agitation, as provided by the drum blancher.
-
04
Overall height
For high throughputs with limited headroom, the horizontal blancher’s lying design is the right choice.

Frequently asked questions
Blanching: frequently asked questions
In the screw blancher via the speed of the screw. It keeps the residence time constant, so that every piece is blanched for the same length of time at the same temperature.
Which time and temperature are right is determined by the purpose of blanching. We fix concrete values during design, based on your raw material.
Thanks to its defined residence time, the screw blancher delivers very uniform blanching quality and is a core component of the French fries line. The horizontal blancher offers high throughputs at low overall height in a lying design.
The drum blancher agitates the product gently with a rotating drum and is therefore suited to delicate produce.
Depending on the product: inactivating enzymes, leaching out sugars or preparing the texture. The purpose determines temperature and time.
Blanching evenly means every piece gets the same time at the same temperature. That is the yardstick for the design, and it is why we ask about purpose, piece size and throughput before we quote.
