BAKED GOODS MARKET LEADER REAPS MAJOR BENEFITS FROM PROCESS UPGRADES
n the highly competitive baked goods sector, it always pays to be prepared - and have your process control systems and production lines fully up to date and cutting edge. When a market-leading baked goods and mixes specialist needed to up its game by improving productivity, it looked to long-term partner Promtek for the optimum solution.
The customer is a leading UK manufacturer of baked goods and mixes based in the Midlands, with family values that ultimately guide the business in how it operates. With over 100 years of expertise in flagship baked products and ingredients, unmatched international manufacturing and distribution capabilities, the company is one of the world’s largest suppliers of bakery solutions. Promtek has been the company’s main process control supplier since 1993 and, in the last two decades, has completed many partner projects. This latest project presented Promtek with the challenge of improving all aspects of its weighing process; the real challenge lay in implementing the necessary upgrades with minimum downtime and disruption to production schedules. A top-quality weighing system takes full advantage of modern hardware and software. Additionally, a weighing system can come in many configurations but typically includes one or more load cells that support a weigh vessel, a junction box, and a weigh controller. They can be affected by many issues including load cell accuracy, and environmental forces. So, it is important to choose the correct machinery and technology to get the best and most accurate results from your weighing system. Promtek’s StoraWeigh9000 platform met – in fact far exceeded - the customer’s requirements. The platform is a feature-rich process control system that can handle any bulk material handling process that runs on all major Programmable Logic Controller (PLC) hardware and allows them to be mixed freely. Additional improvements implemented by Promtek’s engineers to the production line included:
Downscaling the hand addition from six to three bins – this resulted in reduced pipe works in the factory.
Blow lines were upgraded and replaced by modern vacuum exhausters controlled by the latest ‘soft start’ motor starters. This greatly improves energy consumption and improves the motor’s lifespan by reducing wear and tear during start/stop cycles.
A full rewire to separate different parts of the system into more defined control panels.
The latest high-definition graphics package installed and improved remote access. This was a key pillar of the upgrade, ensuring that the system could be available for technical support and open the opportunity for technicians to work from home. That is a real boon for companies looking to adopt a more flexible working environment.
By implementing lean improvements to the line, the company became more efficient, saved money, improved automation and was more effectively future proofed. The new weighing vessels increased weighing accuracy and the new control panels deliver the raw materials in a vastly more efficient and consistent way. The reduction in bin numbers decreased manual handling and increased the overall factory floor space, a space saving measure with a real cost saving benefit. The reduced pipe work brings lower maintenance costs - another considerable saving - whilst modern vacuum exhausters help to conserve energy and protect the motors, increasing longevity and reliability. The software contains highly repeatable raw material silos to auto weighers. This feature’s control system runs at variable speed of all the measurables during manufacturing.
