Flow meters estimate the arrival of the product at the push-out point based on the system flow rate; turbidity sensors monitor the interaction between a light beam and the liquid; and conductivity sensors operate by measuring the electrical conductivity of the liquid. "A solution that can be scaled easily across the plant has been our goal from the start. We use sophisticated machine learning techniques to quickly calibrate our system to new liquids. The result is actionable information, like percentage of water in the product, which is transferred to the plant automation system, enabling process optimization," Järveläinen continues. Collo sensors were recently installed in four locations in the raw milk reception of a dairy plant processing 243 million liters of raw milk per year. The plant previously used flow meters for controlling the push-outs. However, due to their low accuracy, what appeared to be optimal timing actually resulted in losses amounting to 600,000 liters per year. With the far higher accuracy of the dielectric sensor, 108 times better than the flow meter, losses were reduced to just 5,000 liters per year – a reduction by more than 99%. The dairy has now decided to introduce Collo's solution throughout the plant and to automate the process. Large dairy and other food producers are currently increasing their efforts to reduce their environmental impact ahead of environmental targets that loom in the near future, mainly in 2025 and 2030. Most of the greenhouse gas emissions caused by dairy operations originate at the farm. For instance, Nestlé, in its sustainability report, outlines how just 5% of its greenhouse gas emissions comes from its own operations, whereas 95% is made up of emissions in the supply chain. Raw milk production is the largest single source of emissions in dairy production, which any waste of milk-based raw material needs to be prevented and, preferably, eliminated. In addition to the regulatory requirements, changing consumer preferences is another powerful incentive for dairy producers to implement more eco-friendly production methods. A study by McKinsey and NielsenIQ found that products making claims related to sustainability have faster market growth – over a 5-year time span, such products grew about 18 percent more than the expectation was at the beginning of the period. www.collo.fi End
