Brewing combines the art and science of crafting beer to produce flavors and styles that define your brewery. Having control over your process allows you to brew a consistent product and enables the exploration of ingredients and techniques to exercise your creativity. Just as science facilitates the art of brewing, automation facilitates the science. Here we’ll consider a few key aspects of brewing and how automation improves your process and reduces operational costs.
Temperature control is critical to repeatable brewing. A control loop to monitor your hot liquor temperature and regulate your heat source (heating elements, steam valves, or burner) will quickly heat the water without overshooting the target. For breweries using a CLT, automating your blending valve to mix cold water with your hot liquor allows you to keep hotter water in your HLT, increasing your hot water yield for double batching or for your CIP process.
In your mash tun, the controls will regulate pump speeds to circulate through your HERMS coil or RIMS tube....
