STARCH & PROTEIN

World-wide demand for starch and vegetable protein products is growing daily and centrifugal separation technology is a critical element for meeting this demand. Industrial success depends on a combination of increased productivity, premium quality and the economical use of resources.

Starch is obtained predominantly from starch-rich plants such as wheat, potatoes, maize, rice, peas and tapioca. Starch is the material in which plants store reserves of energy, it is a polysaccharide consisting of glucose units. Depending on botanical origin, the starch grains, grain-size distribution and molecular composition of the molecules may vary. The principal components of the glucose units on which the physical properties of starch depend are amylose and amylopectin. It is on these components that the starch’s viscosity and gelatinisation characteristics depend. Among the most important technical properties of starch are adhesion, binding, thickening and stabilisation.

Its functional properties can also be subsequently modified by means of mechanical, chemical and thermal processes, yielding tailor-made products for industry. Today, there are some 1000 different starch products used for a variety of applications such as the making of noodles, farinaceous foods, grape sugar, for sizing paper and thickening paints, to cite only a few examples. Apart from its traditional use in the food and paper industries, highly effective developments for, among other things, detergents, cosmetics, pharmaceuticals and biodegradable products are becoming ever more important. The resulting increase in production and the potential for end-product diversification demands ultra-modern production systems. Today Huading Separator continues to supply various centrifugal separation solutions for starch extraction.

Vegetable proteins are among the most important nutritional resources. At the same time the fascinating properties of proteins are constantly opening up new potential applications to industry. To profit from this diversity these valuable substances must be isolated with a high degree of purity so that they are suitable as tailor-made proteins for further processing. On this basis Huading Separator has developed various techniques and is constantly improving existing processes. The outcome is integrated plant systems and process lines which treat renewable raw materials sparingly, are highly automated and consume much less water and energy than was possible in the past.
