Process Flow of Corn Soya Blend<\/p>\n
Corn soya blend (CSB) is a well-recognized fortified blended food used all around the world to support the eradication of malnutrition.\u00a0 This product is in high demand for both children and adults.\u00a0 International relief agencies such as the World Food Program and UNICEF as well as many charitable organizations support CSB production by purchasing and distributing it in places of need.\u00a0 CSB is primarily comprised of corn and soybeans with the addition of vitamins and minerals.\u00a0 The process flow for creating CSB includes several steps.\u00a0 Furthermore, these steps must be taken to ensure a quality product with high nutritional value.\u00a0 An example of a typical CSB process flow is as follows:<\/p>\n
Cleaning<\/strong><\/p>\n It is important to start with fresh, high-quality corn and soybeans.\u00a0 These components are typically cleaned in an air screen cleaner followed by a de-stoner.\u00a0 These machines are intended to remove foreign materials including substances that may be hazardous to human health.\u00a0 The air screen cleaner uses a series of screens to clean by size.\u00a0 Material that is larger or smaller than the corn and soybeans will be separated and removed.\u00a0 The air screen cleaner also includes a vertical air stream which removes very light or fine material.\u00a0 After the air screen cleaner, a de-stoner is used for additional cleaning by density.\u00a0 The de-stoner will remove materials that are the same size as the corn and soybeans but heavier.\u00a0 This typically includes stones and dense soil peds.\u00a0 These machines help automate the process, but manually cleaning the beans is a common and low-cost alternative for those new to producing CSB.<\/p>\n Dehulling and Particle Size Reduction<\/strong><\/p>\n After cleaning, soybeans are typically dehulled.\u00a0 This includes cracking the soybeans with a roller mill to loosen the hulls.\u00a0 Then an aspirator and sifter are used to separate the hulls from the soybean pieces.\u00a0 Finally, a hammermill is used to grind the reclaimed soybean pieces to a consistent particle size.\u00a0 Corn, alternatively, does not need to be dehulled and can go straight from cleaning to the hammermill.\u00a0 The same hammermill can be used to grind the corn to a consistent particle size that matches the soybeans.<\/p>\n Mixing and Extrusion<\/strong><\/p>\n After grinding, the ground corn and soybeans are stored in separate bins.\u00a0 These components are then metered into a mixer at an approximate corn to soybean ratio of 80\/20 or 70\/30.\u00a0 The mixed product is then heat treated and cooked using an extruder.\u00a0 This is the most important step in the process.\u00a0 The extruder works to pre-gelatinize starches, improve digestibility of proteins, and deactivate anti-nutritional factors.<\/p>\n Cooling, Blending, and Packaging<\/strong><\/p>\n After extrusion, it is necessary to cool the product to a safe storage temperature.\u00a0 Depending on the capacity, a rotary drum cooler or a counterflow cooler are good options for fulfilling this task.\u00a0 Due to the relatively large and variable particle size of the extruded corn and soybean mix, additional grinding is required.\u00a0 A second hammermill is used to grind the material to a consistent final particle size.\u00a0 Now the product is ready to have vitamins, minerals, and sometimes sugar added.\u00a0 This needs to be metered as these components are added to the corn and soybean mix in specific and small quantities.\u00a0 The next step is to mix the product using a second mixer to create a uniform and homogenous product.\u00a0 The product is finally ready to be packaged in the desired size bag and distributed.\u00a0 Much like cleaning, some of these processes (such as premix addition and bagging) can be more manual to reduce initial investment costs.<\/p>\n While this process may vary slightly, this is a general approach to manufacturing CSB.\u00a0 The quality of incoming material, specific final product requirements, as well as other factors determine the final process.\u00a0 Our primary goal is to help you be successful in developing optimized products using extrusion technologies.<\/p>\n","protected":false},"excerpt":{"rendered":" To finish off an exciting and productive 2023, we want to share with you one of our most viewed and most shared blogs of the year!
