A sweet tradition

Bosch TurboMixxGerman confectioner Jahnke has increased product quality and saving up to 60 per cent energy with updated confectionery production lines from Bosch. Headquartered in Kaltenkirchen, Germany since 1989, the company’s confections continue to be produced at its sole manufacturing facility according to traditional recipes with the help of the latest production methods.

In 1989 founder Rudi Jahnke’s nose for business led him directly to the Bosch factory buildings in Viersen, Germany. For the past few years, Jahnke has exclusively utilised a complete line of Bosch machines for every step of the production process, from manufacturing to packaging.

Reduced energy- and water consumption

Jahnke began to search for ways to conserve both energy and water and thus reduce production costs. The new dosing and mixing unit BDK 2000 G from Bosch met the challenge and delivered on all counts.

Until the changeover to BDK 2000 G, Jahnke used an electronic dosing and mixing unit to whisk sugar, glucose and water together, a mixture that was then added to the pressure dissolver.

Though satisfied with the machines that delivered consistent, high-quality product, Jahnke faced ever-increasing energy and water costs and needed technology that demanded less of both components. The BDK 2000 G’s continuous dosing and mixing unit makes it possible to produce a crystal-free sugar-glucose syrup-solution without the addition of water.

It also realises significant savings in energy consumption. The machine’s integrated TurboMixx mixing system dissolves the sugar into the glucose syrup to create a homogenous mixture, eliminating the need for the addition of water. The Rapidsolver heat exchanger, integrated into the BDK 2000 G, dissolves the mass into a crystal-free solution, also allowing the production to be interrupted without product loss. Since the required moisture level is already reached after the dissolving process, cooking to reduce water content is no longer necessary, saving significant amounts of energy and eventually reducing production costs.
