Waterjet Cutting Food

For decades,Water jets have been used for decades as a manufacturing process for cutting food of all types including pizza, cakes, lettuce, celery, meat, frozen fish, bacon, sandwiches, cupcakes, candy bars, granola bars and all types of frozen foods. Pure water cutting up to 90,000 PSI/6,200 bar provides maximum added value by cutting produce, meat, bakery and confectionery products in a hygienic environment, avoiding cross-contamination that occurs in blade cutting systems. 

According to Food Production Daily magazine, “Waterjet technology is one of the fastest growing major machine tool processes in the world because of its versatility and ease of operation.” Mach’s incredible speed for cutting has been approved by the USDA to create an aseptic and hygienic cutting process method.

Waterjet Advantages over Mechanical Blades from winwin Customers: 


  1. Reduced particulates on the blade which requires maintenance and significant QC.

  2. Reduced product mulching or build up in the system mechanisms which requires shutdown and cleaning in mechanical systems, often disassembly to some degree.

  3. Reduced zone 1 swabs for QC; generally looking for listeria. Zone 1 is any direct food contact surfaces and any pathogens found in this zone will contaminate the product. Facilities are required to regularly swab these and monitor the results and are audited at random. Big labor cost.


Waterjet cutting technology can be applied to various cutting and slicing applications in the food industry. Here are some ways waterjet cutting is used in food processing:

Portioning and Slicing: Waterjet cutting is commonly used to accurately and consistently portion and slice food products. It can be applied to meat, fruit, vegetable, cheese, cake, bread and other foods. High-pressure water jets cut these materials precisely without crushing or distorting them.

Sandwich assembly: Waterjet cutting can create precisely shaped parts for sandwiches and other foods. It cuts bread, deli meats, cheese and vegetables to specific shapes and sizes for uniformity and good looks.

Pizza Cutting: Waterjet systems can be used to cut pizza into desired shapes and sizes. Whether it’s round, square or custom-shaped pizza, waterjets provide precise, efficient cutting solutions.

 Confectionery and baked goods: Waterjet cutting is used in the production of confectionery such as chocolate, candy and nougat. It can also cut delicate baked goods such as cookies, pastries and cakes with intricate designs.

What are the advantages of water jet technology in food processing?


  1. Precise Cutting: Allows for consistent portioning and slicing of food products

  2. Hygienic cutting: avoid cross-infection caused by blades in alternate cutting

  3. Reduce waste: the cutting water column of the water jet is very thin, which can reduce the waste of food during the cutting process


Waterjet cutting is therefore a very valuable cutting tool in the food sector, providing precise dividing, slicing and shaping capabilities while maintaining product quality and hygiene.

In addition to food, candy and vegetables, water cutting technology also has greater advantages in frozen food applications.

How water cutting technology cuts frozen tuna?

Shenyang winwin waterjet, the frozen saury project tailored for customers, the video show the project

Tuna is a seawater fish belonging to the tuna family (scientific name: Thunnini) under the scombroid family. This family includes 15 species of tuna in 5 genera. The size varies greatly among the species. The smallest tuna is bonito, which has a maximum length of 50 cm (1.6 ft) and a weight of 1.8 kg (4 lb); the largest The tuna is the northern bluefin tuna, which has a maximum length of 4.6 meters (15 feet), a weight of 684 kilograms (1,508 pounds), an average length of 2 meters (6.6 feet), and is believed to live up to 50 years.

To cut frozen tuna, common tools:

Chef’s Knife: A sharp chef’s knife is a versatile tool that can be used to cut tuna into various shapes, such as steaks, fillets, or cubes. 

Boning Knife: A boning knife is a thin, flexible knife with a sharp tip. It can be used to remove bones and skin from tuna, and can also be used to fillet the fish. The flexibility of the blade allows for precise cuts. 

Sashimi Knife: A sashimi knife, also known as a lancet, is a traditional Japanese knife used specifically for slicing raw fish. .

Butcher’s Saw: If you need to cut larger, thicker pieces of frozen tuna, you can use a butcher’s saw.

The advantage of waterjet cutting frozen fish .

But in the face of the huge blue flag tuna, after being frozen, the ordinary slaughtering data is no longer suitable for cutting, so how to cut frozen tuna, more companies are looking for solutions, the water cutting robot solution provided by winwin water cutting , the most prominent of which

1. 6200bar/90000psi ultra-high pressure water cutting booster pump can easily cut 500mm frozen tuna, which is thicker than traditional slaughtering knives

2. Save labor costs, fully automated water cutting projects can reduce the use of workers and save labor costs

3. Cleaner and hygienic, there will be no pollution during tool replacement and use, making raw materials more hygienic

Shenyang winwin waterjet cutting, as the leader of waterjet cutting in China, provides customers with tailor-made solutions to help customers solve problems encountered in cutting, from 60000psi to 90000psi, from Gaza cutting to water storage cutting, from platform cutting to portable Cutting, only customers have cutting needs, winwin’s technical team can provide solutions according to the actual situation of customers
