Food Processing - September 2007 - (Page 38)

MANUFACTURING MODELS readily apparent. ANSI/ISA S88 is a 10year-old international standard that contains models and terminology for controlling batch processes. The models provide a hierarchical and modular categorization for the machines and devices that carry out the process and for the recipes that describe how to manufacture the product. They form the basis for managing the production process and thus ensure standardization within batch process automation. S88 allows manufacturers to write software that structures the equipment and the procedures of batch processing operations. Equipment logic that has been developed according to the S88 standard can be changed or adapted with minimal, perhaps no, adjustments being necessary in other implementation modules or in master recipes. Procedures can be developed and changed without taking any implementation aspects into consideration. But change control is automatic. ANSI/ISA S95 is taking this automation effort one step further. The standard was developed to integrate enterprise and batch control systems. S95 allows the exchange of batch recipe information between enterprise resource planning (ERP) systems and manufacturing execution systems (MES). Changes in a recipe can be automated as they are sent to the ﬂoor. Perhaps more importantly, master recipes – and changes that corporate engineering makes in a master recipe – will work in all plants anywhere in the world that conform to the standard. But once again, change control is automatic. It’s taking a while for the standards to take hold in the food world. In our own Annual Manufacturing Trends survey (www. foodprocessing.com/articles/2007/016. html) from January, just 19 percent of respondents had heard of the standards and 8 percent were using them in any way. Cerveceria Polar, a large Venezuelan brewer, used the standards to better control the brewing process. The automation they brought to the process enabled a 50 percent reduction in lauter time, the elimination of a process engineer (now the brewmaster can control and reprogram the process) and the manufacture of six batches of beer in a 24-hour period instead of ﬁve. Because beer increasingly is being made in more varieties but smaller batches, the company can quickly respond to market preferences and changing consumer tastes. “The brewmasters were worried at ﬁ rst,” Francisco Ferrero, automation manager for the brewer, told a Rockwell Automation Fair audience last fall. “But after using it, they’re not just satisﬁed, they are delighted.” MORE ON THE WEB The S88 and S95 standards were developed by ISA (formerly the Instrument Society of America) and there’s plenty about those standards on its web site: www.isa. org. Also shepherding their development is the World Batch Forum: www.wbf.org. Contact your Wilden authorized distributor today at www.wildendistributor.com.
