5 advantages – waterjet cutting food

Waterjet cutting of food products offers a variety of advantages. Thanks to its precision, it allows the creation of complex shapes and fine cuts in food without deforming or damaging it. The method does not generate heat, which is especially important to preserve the quality, nutrients and flavor characteristics of delicate foods.

From soft breads and cakes to hard nuts and root vegetables, waterjet cutting can process a wide range of foods accurately and efficiently. The technology offers a hygienic cutting solution as the cutting process takes place without direct contact with the food, minimizing contamination. In addition, precise cutting reduces product loss and waste, resulting in greater efficiency and economy in food processing.

The cutting heads and nozzles used are made of food-grade materials to ensure that no undesirable substances get into the food. The cutting medium, usually water, is natural and non-toxic. No additional lubricant or oil is needed, which ensures food purity. In addition, waterjet cutting enables the cutting of multiple layers of food at the same time, which increases productivity. Overall, waterjet cutting helps to produce high-quality, hygienic and aesthetically pleasing food products.

Precision

Exceptionally precise cutting for complex shapes and fine cuts.

No heat generation

Food is not heated during cutting. Especially beneficial for delicate foods.

Material diversity

Cutting from soft bread and cakes to hard nuts and root vegetables.

Hygiene

Cutting process without direct contact leads to a high quality of hygiene.

Low product losses

Precise cuts minimize the amount of waste and product loss and increase efficiency.

Technical details

Waterjet cutting of food products is based on the use of a high-pressure water jet that is directed through a special nozzle. The water jet is directed at the food to be cut at very high speed, creating a precise cutting effect. The intensity of the water jet can be adjusted according to food type and density to achieve the optimum cutting quality.

Waterjet cutting in the food industry also uses abrasive materials in some cases, such as fine particles of abrasives, to increase cutting performance.

The technical details of waterjet cutting allow high flexibility in the design of cuts and patterns in food products. With the help of computer-controlled cutting heads, the shape of the water jet can be precisely controlled, which makes it possible to realize complex shapes and cuts. In the food industry, the precise cutting capabilities offer innovative design possibilities for packaging, presentation and the development of new food products.

As a rule, soft and delicate foods, such as bread, cakes or fruit, can be cut in very thin layers, often in the range of a tenth of a millimeter. This precision allows for a fine and clean cut edge without crushing or deforming the food.

With the addition of abrasives, the waterjet can intensify its cutting action and reach material thicknesses of several centimeters.

Any shape cuts and bevel cuts up to 60° are possible.

The cutting accuracy is usually +/- 0.1 mm.

In waterjet cutting, the cut quality is basically divided into 5 quality levels.

  • Separating cut Q1 (for blanks / semi-finished products)
  • Standard cut Q3 (the most common cut)
  • Fine cut Q5 (for optimum dimensional accuracy)

For waterjet cutting of food, the achievable cutting speeds are usually between 1000 and 6000 mm per minute.

As a rule, the water pressure for cutting food is between 2000 and 4000 bar.

CNC control enables precise and repeatable cutting. The STM SmartCut cutting software offers high ease of use and functionality as well as flexibility.
