In this edition of Ask an Expert, we look at the benefits of a groundbreaking system solution for spent grain transfer for breweries.
Q: Can you explain what this system is and how it benefits breweries?
A: The Smart Air Injection (SAI) system of a renowned pump manufacturer is an advanced solution designed to enhance the efficiency of transporting brewing by-products, particularly spent grain. This system significantly reduces the consumption of compressed air, a major energy expense in conventional methods. By combining an open hopper progressive cavity (PC) pump with pneumatic dense phase conveying, the SAI system efficiently transfers spent grain over long distances with controlled air pulses. This leads to considerable energy savings and contributes to breweries’ sustainability goals.
Q: How does the SAI system compare to traditional methods of handling spent grain?
A: Traditional pneumatic systems for handling spent grain are energy-intensive as they use continuous compressed air. These systems are prone to blockages and require a lot of energy to move the by-products over long distances. The SAI system, on the other hand, uses a discontinuous method where spent grain is moved in plugs with intermittent air pulses. Additionally, it minimises pipeline wear due to lower flow velocities, further enhancing system efficiency and longevity.
Q: Can you discuss the environmental impact of using the SAI system in breweries?
A: The SAI system’s reduced air consumption directly translates to lower electricity usage, which helps breweries reduce their carbon footprint. The SAI system aligns well with sustainability initiatives by halving the time required for spent grain transfer and cutting air usage by more than half. It reduces energy costs and supports breweries in achieving their carbon reduction targets, making the brewing process more eco-friendly.
Q: How does the SAI system handle variations in the moisture content of spent grain?
A: One of the key advantages of the SAI system is its flexibility in handling media with varying moisture content, ranging from 60 to 85 per cent. This adaptability ensures that the system maintains high efficiency regardless of the moisture levels in the spent grain.
Q: Can you elaborate on the integration capabilities of the SAI system with existing brewery operations?
A: The SAI system is designed for easy integration in breweries. Its advanced control technology can seamlessly fit into current processes without requiring major overhauls. This ease of integration makes it a versatile and practical solution for breweries looking to modernise their spent grain handling operations while maintaining operational continuity.
Q: What feedback have you received from breweries that have implemented the SAI system?
A: Feedback from breweries has been overwhelmingly positive. They appreciate the significant reduction in energy consumption and the associated cost savings. The improved efficiency and reduced transfer times have also been highlighted as major benefits. Breweries and operators have noted the system’s reliability and reduced maintenance needs due to lower pipeline wear. Overall, the SAI system has proven to be a valuable investment for breweries aiming to enhance sustainability and operational efficiency.
