MIXING EQUIPMENT
Engaging with Bürkert, engineers Kieran Bennett and Chris Hughes from the flow specialist specified the FLOWave flowmeter. Free of seals, electrodes, and components within the flow path, the device minimises the potential of bacteria accumulation and is easy to clean. To achieve accurate flow measurement, FLOWave sends high-frequency Surface Acoustic Waves (SAW) across the fluid where changes in flow, mass, temperature, and density, affect the waves’ speed and attenuation. The resulting detection of the signal achieves precise measurements without direct contact with the media.
REDUCED WATER USE IN CIP Bürkert’s FLOWave was also specified to improve the cost effectiveness and time required for CIP. A typical cleaning process operates by setting cycle times of chemical washes followed by clean water flushes. To ensure completeness of the flush, conservative estimates are applied, but this results in a high volume of water use. However, FLOWave can detect the phase change in the media, referred to as the differentiation factor. This accurately informs when all chemical traces from the CIP process have been flushed away, enabling a shorter flushing period and reduced water use. With at least one CIP process per day, and tens of thousands of litres of water involved per year, the cost and time saving is significant,” says Kieran Bennett, Bürkert. “Total water saving can be up to 50 per cent, which also achieves a significant environmental benefit.”

live in May, and its flow control accuracy is already improving production efficiency.
IMPROVING PRODUCTION EFFICIENCY “Previously, challenges in accuracy controlling the flow of spirits using mag-based flow meters meant continually adjusting the mixture, adding highly purified water to help meet the ABV level, as well as sugar and other ingredients,” explains Gary. “Now, with Bürkert’s FLOWave, we can get a much more accurate measurement of what’s going into a mixing tank before pumping it to the line. From initial batches of 500 litres, each one has been accurate to less than two litres difference.” The flow meters are installed within an ATEX Zone 2 hazardous area, while the devices communicate back to a Bürkert ME61 display located in a separate control room. The FLOWave device integrates analogue and digital outputs, and by wiring the digital communication ports together in a daisy chain formation, a single cable, approximately 25 metres long, connects to the display via Bürkert’s EDIP CAN-based protocol. Providing individual batch and total flow rates, the data enables ICB Distillers’ operations team to accurately keep track of produce. With the additional flow meters set to be commissioned in the following months, ICB Distillers will be in a position to extend the pigging system across the matrix. Minimising spirit wastage and reducing the volume of water used in the CIP process is set to achieve a rapid return on investment for the beverage producer. Meanwhile, less time required for the updated cleaning process has the potential to improve productivity while maintaining the same high level of hygiene.
