Baked beans in tomato sauce are one of the most processed convenience products in the world. Whether in retail, communal catering or industrial processing, canned beans are opened and emptied in large quantities and under high time pressure. Something that is often underestimated: The product itself places high demands on the entire opening and emptying process.
This use case describes why baked beans place special demands on industrial can openers – and which solutions KA-Process offers for this application.
Application scenarios: Where baked beans are processed industrially
Canned baked beans are used in various industrial contexts:
- Repackaging: From standard cans into alternative container formats for restaurants, canteens or catering businesses
- Ready meals and combined menu components: Baked beans as a stand-alone component in ready meals, portioned and heated together with other ingredients
- Further processing in complex ready meals: With downstream mixing, dosing or heating processes
In all of these scenarios, the cans must be opened continuously, cleanly and at a high cycle rate. At the same time, controlled and complete product discharge is crucial – for the quality, hygiene and cost-effectiveness of the overall process.
Product-specific challenges
Baked beans combine several properties that make the opening process challenging.
1. pressure-sensitive, soft beans
Due to the thermal treatment in the production process, baked beans are soft and sensitive to pressure. They tend to burst when subjected to mechanical stress, which leads to a loss of structure and an undesirable “sludge content” in the product. Any unnecessary pressure during discharge can have visible quality consequences.
2. high viscosity, sticky tomato sauce
The tomato-based sauce is significantly thicker than aqueous media. It flows more slowly, sticks to surfaces and makes it difficult to empty the can completely. The result: product residue in the can, build-up in the system and increased cleaning effort.
3. inhomogeneous multiphase system
The ratio of beans to sauce is not constant within a can and from can to can. Local accumulations of solids lead to uneven discharge and can cause blockages at transfer points.
The KA-Process solution
KA-Process has designed its can opener systems specifically for demanding, viscous products such as baked beans. The approach: maximum yield through mechanical support.
Knocking function for emptying optimization
A key advantage for processing baked beans is the integrated tapping function: the can is tapped in a targeted manner via the clamp, which gently removes adhering product residues – beans and sauce – from the inside wall of the can. The result is a significantly higher yield.
Flexibly adjustable emptying time
The emptying time can be set flexibly in the program so that the can is held in a tilted position for a longer period of time. This allows the product to flow gently and continuously out of the can without the need for additional aids.
Conclusion: Yield optimization without compromising quality
With baked beans, the quality of the opening and discharge system directly determines product quality and production efficiency. Those who rely on unsuitable discharge technology pay the price in terms of sludge content, product loss and increased cleaning effort.
The KA-Process solution combines a defined opening process with mechanical knocking support – and thus provides a stable, hygienic and gentle discharge, even for demanding bean products in viscous sauce.
