The cookie monster would be pleased: thousands of delicious confectionery products are kneaded, stamped, baked, cooled and packed every hour in a biscuit factory. Wide conveyor belts transport the baked goods from station to station. In biscuit production, for example, they are taken to rollers that thin the dough and then finally to stackers in which the finished biscuits are stacked one after another. In the meantime, they are baked in ovens that are as long as an underground train. These ovens accommodate thousands of biscuits at a time and, afterwards, the biscuits all come out perfectly cooked. A lot of experience is required for a perfect synchronisation – something that Ing. Polin E C. S.p.A., manufacturer of industrial bakery equipment, can claim to have. Founded in 1929 in Verona, Italy, the company built tunnel ovens as early as the 1930s. Today, the ovens and machines from Verona are in demand around the world in the production of biscuits, bread and sweet baked goods due to their high quality and efficiency. Polin designs and produces tailored solutions that offer high productivity, operational continuity, as well as time and cost optimisation.

4,000 kilograms of biscuits per hour

The systems from Verona are also in demand in Asia. Recently, Polin built a production line that produces around 4,000 kilograms of biscuits per hour: 24 hours a day, seven days a week. Enough to stop even the cookie monster from wanting more. Even for a company with as much experience as Polin, this was challenging. To meet the challenge, Polin is only using particularly powerful and robust components. For example, for the automation side, the company is relying on the expertise of Automation System Srl, which is also based in Verona and has been designing and producing software and hardware solutions for industrial automation since 1999, including for Polin’s baking systems.

Complete solution from LAPP

Automation System also recommended working with LAPP on the connection systems. Together with the global market leader for integrated connection solutions based in Stuttgart, the automation experts designed the cabling system and the connections for the new production line. It consists of three parts: 60 metres of cable are inserted in the machine that shapes the biscuits from the dough, 104 metres of cable are used in the oven and 150 metres of cable are installed in the cooling system. LAPP succeeded in satisfying all customer requirements. Alongside ÖLFLEX® control cables and pre-wired ÖLFLEX® CONNECT servomotor cables, LAPP supplied a complete package of industrial data transmission solutions. The package comprises the following components: ETHERLINE® Cat.5 data transmission cables for industrial networking of PROFINET applications, the associated EPIC® DATA RJ45 and M12 industrial connectors, ETHERLINE® patch cables and the ETHERLINE® ACCESS U05T and U08T industrial switches.

Longevity, comprehensive consultation, short delivery times

“We recommended LAPP as a supplier because we were convinced that its quality and broad product range would certainly meet the special requirements Polin had for this project,” says Massimo Urbani, owner of Automation System. LAPP is the ideal partner for many reasons: for one thing, LAPP is known for the high quality and longevity of its products. A cable defect leading to a system stopping and tonnes of dough or burnt biscuits having to be thrown away was not an option. Furthermore, LAPP was able to offer convincing solutions for all the required components, including industrial data transmission – and all that from a single source and with a high level of product and solution expertise. “The extensive consultation given when selecting suitable components gives us real added value,” said Urbani. According to Urbani, another major advantage was being able to make online purchases with very short delivery times. This shortens the time before a new system is launched on the market. Extensive certifications (IEC/EN, UL/UR, CSA, EAC) also guarantee immediate operational capability in various applications in the food and beverage industry.

“Our experts’ close collaboration with our customers and partners is a basic principle for LAPP. Their satisfaction is the top priority,” Marco Artoli, Product Manager at LAPP Italia, reveals the secret to success. “The search for outstanding quality was what connected Polin, Automation System and LAPP in this challenging project, and our complete solutions in the field of industrial communication impressed the customers.”
