Innovative Chewy Candy Production Line Increases Product Quality and Reduces Energy Consumption


Bosch at Interpack 2011

* New dosing system significantly reduces energy consumption
* Minimal floor space needed through rapid inline crystallization
* Advanced product quality through continuous processing

Bosch Packaging Technology introduces its new chewy candy production line during Interpack 2011 at the in-house show in Viersen, Cologne. High-quality chewy candy can now be produced cost-effectively and rapidly with the new line that eliminates the energy-intensive cooking stage and the need for intermediate storage during crystallization. Featuring the continuous dosing system BDK 2000 A and the crystallizer BZK 1000 B, the advanced line allows significant savings in energy consumption, processing time and floor space. “With ever-increasing energy costs and competitive pressures, manufacturers need productivity-enhancing lines that can guarantee high quality.”, said Andreas Leitze, Senior Manager Technical Support, Bosch Packaging Technology.

The new line’s continuous dosing and mixing unit BDK 2000 A makes it possible to produce a sugar-glucose syrup-solution without the addition of water. The unit’s integrated TurboMixx mixing system produces a homogeneous mix by dissolving the sugar into the glucose syrup. For the utmost in dosing precision it features a gravimetric system with load cells and a flow meter. The subsequent dissolving process in the Rapidsolver heat exchanger guarantees a crystal-free solution, which also allows production to be stopped and started without product loss. The mass is heated by flowing around a pipe bundle containing steam. In the case of machine stoppages, the mass is not damaged due to the small steam volume and quick steam release. As the required moisture level is already reached after dissolving, cooking is not necessary any more to reduce water content, saving significant amounts of energy and reducing production costs. Gelatine or other gelling agents can be gently added after the dissolving process. Reduced processing time and minimal floor space are additional benefits of the chewy candy production line. The BZK 1000 B allows for rapid inline crystallization eliminating the need for interim storage, avoiding lengthy storage times that disrupt production, and reducing manual labor requirements. The mass can be directly fed into a subsequent filling and forming line.

The new chewy candy production line as well as a production line for puffed rice marshmallow bars will be on display and in production at the in-house show at Bosch’s site in Viersen, Germany during Interpack. Visitors to Interpack 2011 in Düsseldorf can use the shuttle bus on selected dates from the trade show to Viersen and back.
