ABSTRACT
Process control applies engineering and technology to harness brewing scientific knowledge in the quest for consistent high quality beers at a competitive cost. This chapter shows the key performance indicators to be measured and controlled to ensure that brewhouse quality and efficiency targets are being achieved. It terms 'process control', referring to online measurement and real-time process regulation as part of a fully automated system. Process management is used to refer to the adjustment of system control values based on off-line measures and also to the management of any interfacing nonautomated activities. The chapter outlines a review of the required beer characteristics. Final wort composition has predefined limits set by the specifications for brewing materials and water, but the final composition can be influenced by any of the brewhouse unit operations. Typical online measurement and control techniques are described and, where appropriate, guidelines are offered for correct instrument installation, plant safety, and product protection.
