Interpack exhibitor Multivac, too, is able to fall back on their experience from a wide range of different projects for the bakery industry. These include handling very different products, for example, toasties, bread or pancakes – and individually designed line concepts to match. For example, the company has developed a full wrap labelling solution for foldable plastic trays. Pressure-sensitive baked goods like cookies, muffins, donuts, pieces of pie or entire cakes are often packaged in such transparent foldable trays, which are then usually wrapped with a cardboard package band. The conveyor belt labeller by Multivac is said to save up to 70 percent of material compared to labelling with a cardboard package band. The model features servo-driven pressure brushes, which allow for C- and D-labelling of up to 120 packages per minute at a label width of up to 500 millimetres. Other than as a simple top label, a label can be placed in a C-shape over three sides or in a D-shape over all four sides of the packaging. Both the C- and D-labels have the advantage of sealing the package at the same time according to the manufacturer. With the new full wrap labelling solution, Multivac has expanded their portfolio for the baking trade and the bakery industry.
Producing baked goods at high speed
Many systems in the bakery industry work at very high speeds, but at the same time, there is an expectation of constant high quality. Mixing and kneading systems for constant operation, like those of interpack exhibitor Zeppelin, are the tools needed for the job and can produce 20,000 pretzels per hour, two million bread rolls a day or three tons of biscuit dough per hour. Before packaging, many baked goods must be precisely cut to size. Döinghaus offers individual solutions for cutting that utilise ultrasound, among them the universal cutter Ultracut Nado, which cuts both round and angular products. The size of individual pieces and segments, as well as different cutting speeds, are freely selectable using a touch panel with intuitive operation.
And igus GmbH from Cologne, manufacturer of plastic bearings made entirely of plastic as well contributes to seamless operations in the production of baked goods. A greaseless linear system, for example, is being used in an industrial wafer baking system made by specialised mechanical engineering company Walterwerk. The system bakes standardised wafers for the industrial production of ice cream, which are fed into a rolling station and rolled up while still warm. Afterwards, they are transported to the cooling tower over a conveyor belt, before the wafer is given a paper cone in the confection area. In this area, the linear bearings made of tribo-optimised high-performance polymers by igus are used during separating and feeding.
Exhibitors at interpack will present how sensitive baked goods can be safely produced and packaged nowadays from 4 to 10 May 2023 in Düsseldorf. The world’s leading trade fair for processing & packaging offers visitors modern solutions for the industrial packaging of baked goods in Halls 1, 3 and 4.
