Bühler invested in the Vaisala
technology as part of its drive towards digitalisation
CONSISTENT MOISTURE LEVELS IMPROVE PRODUCTION EFFICIENCY
Te monitoring of moisture levels also helps to shorten the time needed to bake the perfect product. “When baking cookies, an oven typically operates with a dewpoint of 60-70°C, but our Meincke Turbu ovens allow the humidity level to be higher,” explains Bøgild. “Consequently, there is less cold air to heat up, because when we regulate the moisture content, less air exchange is necessary. In addition, a dryer oven requires higher temperatures to achieve the same heat transfer, while excessive humidity can damage the oven – so with a higher moisture level that is kept consistent and within safe limits, thanks to accurate monitoring, we can achieve substantial reductions in the energy bills of our customers.” In addition to reduced gas consumption, the conveyer carrying the baked goods can also move through the
ovens at a faster rate because the products are ready sooner, resulting in a more efficient throughput.
FROM AUTOMATION TO DIGITALISATION Bühler is at the forefront of the fourth industrial revolution in its industry, incorporating smart technology into existing automated production facilities to improve performance through enhanced monitoring, reporting, and artificial intelligence techniques. “Te market has slowly embraced this transition, and by recognising the efficiency benefits of having more accurate data and knowing how to use it, we are driving real change in the industry,” Bay explains. “Humidity measurements provide one of the most important insights when it comes to making the baking process more efficient and building an understanding of how heat flow within the oven contributes to final product quality.”
Bøgild sees Vaisala as the ideal partner
for Bühler, helping customers to achieve ambitious efficiency targets. “Vaisala technology is crucial to our efforts, because the sensors are easy to calibrate and use, and robust enough to withstand extreme conditions,” he explains. “Flemming Bøge of Brdr. Jørgensen
Instruments, Vaisala’s partner in Denmark, worked closely with us to help identify the ideal solution; and we also received useful guidance from Vaisala’s own application experts on how to calculate humidity values. Tis greatly benefited our technicians, which use the equipment daily. “Even before we chose Vaisala as a
preferred supplier, we had customers specifying the company’s equipment in their orders. With an increasing demand for digitalisation and AI-enabled functionalities, this need is only going to increase, so we’re excited to see where this collaboration can take us.
