Corn Wet Milling and Refining Applications

1. Introduction 1.1 Rationale and Methodology Over the last twenty years, Flowserve’s Durco Process Pump business has developed a leading presence in the corn wet milling and refining industry. Although technically part of the food and beverage segment, the industry requires chemical process pumps for abrasive corn slurries and numerous other applications. Driving this market today are the corn syrups produced from corn starch. Demand has been on the rise around the world because these corn syrups are 1.) economical sugar substitutes, and 2.) important ingredients for processed foods and beverages, notably soft drinks. In response to increasing opportunities around the world, a global conso lidation is underway in corn wet milli ng and refining. Whereas many small l ocal producers once existed, a handful of large produ cers are emerging. Most have well establ ished operations in North America and West Europe, and are now expanding via acquisitions and joint ventures in developing regions. Given Flowserve’s experience serving corn wet millers in developed regions, as well as this new growth potential in developing areas, it seemed logical to create an applications manual specifically for the wet milli ng and refining processes. The purpose of the manual is therefore twofold: Introduce Flowserve sales personnel to the market as a preparation to pursue new pump business, especially in Asia Pacific, East Europe and Latin America Consolidate and share Flowserve’s modular pump experience in this market so that all sales personnel can offer proven pump solutions. This manual represents the collective work of numerous Flowserve sales engineers and other personnel who have knowledge of the indust ry. Resources for further information include Corn Refiners Association (Washington, DC USA), the Association Des Amidonnieries De Cereales De L’UE (Brussels, Belgium), and the textbook Technology of Corn Wet Milling. Corn wet milling, as it is known in North America, is referred to as maize wet milling in Europe and other parts of the world. In addition to corn, other starchy grains, fruits and vegetables are wet milled.
