The German dairy plant Milchwerk Crailsheim-Dinkelsbühl has entrusted GEA with the modernization of its milk treatment area. The next step will see GEA co-operate with the dairy project team to develop an energy and heat quantity concept for the entire plant, thereby unlocking significant CO₂ savings potential.
Energy-efficient raw milk processing
“The technical modernization at the Crailsheim site represents the fulfilment of a long-cherished dream,” says Josef Vögele, managing director of Milchwerk Crailsheim. “Energy efficiency is our top priority when we think about the future of our dairy.” The heat treatment of raw milk, is immensely important for hygienic cheese production, but at the same time it requires a lot of energy if the technology and process integration are not perfectly designed. Vögele was convinced by the fact that key technology and components, such as skimmers, valves, and plate heat exchangers, come from GEA. The next step will see GEA co-operate with the project team of the Crailsheim dairy plant to develop a comprehensive energy and heat quantity concept for the entire plant, thereby unlocking significant CO2 savings potential.
“In Crailsheim they face similar challenges to many other small and medium-sized dairies: Sustainability and digitalization are taking hold – and they can only be implemented by using efficient high-performance technologies and consistent process planning,” describes Steffen Rathmann, Managing Director of GEA TDS. “To tackle these issues, which are so omnipresent in the industry, we develop the process and technology design based on the specific conditions on site. It makes us proud to have the opportunity to set up the technical backbone for the future success of our customers like Milchwerk Crailsheim.”
Digital monitoring of historical plant activity data
In addition to the above technology, the customer opted to record the plant history via GEA Codex Plant Playback. This special GEA automation solution analyzes industrial processes batch by batch as a software-based video recorder. This reveals dependencies, errors, and their causes, which can be easily fixed. The software animates SCADA Historian data in real time or time lapse. This improves both production as well as product and process safety.
New heat treatment technology and process engineering
In order to connect the cheese dairy to the machine room in Crailsheim, GEA will also technologically modify various tank farms, fundamentally rebuilding all valve blocks and the cheese milk tank farm. To ensure high microbiological quality, the dairy will get a new pasteurizer with surplus cream cooling and two new thermizers. During the project, the existing CIP station will be upgraded to state of the art. An additional skimming separator is equipped with GEA proplus, which increases protein yield and significantly reduces fresh water consumption through longer emptying intervals for the milk separator. The cheese production technology is complemented by two new calcium chloride stations which increase yield and improve product quality through stabilized rennet gel. GEA will modernize the dairy without stopping production.
