Starch exists in plants, together with cellulose, protein, oils and fats, inorganic salts and other substances. Starch manufacturing is to extract the starch from plant seeds, root or tuber. The whole starch extracting process utilizes physical separation method, gradually separating cellulose, proteinand other non-starch substances, so that to get pure and white starch powder. The chemical structure of the starch in raw material and the finished starch powder is the same. There are not chemical changes during the starch extraction. But using sulfur dioxide acidity material in the processing may cause a small amount ofstarch molecular decomposition reaction, which can slightly lower thesticky paste degrees of starch.

Starch extracting process needs a lot of water. Raw material cleaning, grinding and each separating process all are all processed in water. Insoluble in water and the “proportion of starch is higher than water and other impurities” are the two main basics for starch processing plant.

Horizontal screw conveyors are the most widely used type of screw conveyor. Used to convey bulk materials from one part of a process to another, horizontal screw conveyors are available in a wide range of sizes, lengths, configurations and materials of construction.

Screw conveyors are typically designed to convey bulk materials at 15, 30 or 45-percent trough loading, depending upon material characteristics of the specific bulk material. As a general rule, trough loading of 45-percent can be used for light, free-flowing and non-abrasive bulk materials. Trough loadings of 15 and 30-percent are typically used for denser, sluggish and more abrasive bulk materials.

Vertical screw conveyors are a very efficient method for elevating a variety of bulk materials at very steep inclines or completely vertical. KWS considers any screw conveyor located on an incline over 45-degrees to be a vertical screw conveyor.

The compact design allows for the vertical screw conveyor to fit into almost any plant layout. With a minimum number of moving parts, the vertical screw conveyor is a cost-effective and dependable component of any bulk material handling process.
