Starch or amylum is a polymeric carbohydrate consisting of a large number of glucose units joined by glycosidic bonds. This polysaccharide is produced by most green plants as an energy store. It is the most common carbohydrate in human diets and is contained in large amounts in staple foods such as potatoes, wheat, maize (corn), rice, and cassava.

Pure starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol. It consists of two types of molecules: the linear and helical amylose and the branched amylopectin. Depending on the plant, starch generally contains 20 to 25% amylose and 75 to 80% amylopectin by weight. Glycogen, the glucose store of animals, is a more branched version of amylopectin.

In industry, starch is converted into sugars, for example by malting, and fermented to produce ethanol in the manufacture of beer, whisky and biofuel. It is processed to produce many of the sugars used in processed foods. Dissolving starch in warm water gives wheatpaste, which can be used as a thickening, stiffening or gluing agent. The biggest industrial non-food use of starch is as an adhesive in the papermaking process. Starch can be applied to parts of some garments before ironing, to stiffen them.

  • The ACM/C series grinders are the result of our latest innovations (Patent Registration No.20031056858) and are specially designed for grinding heat sensitive materials. The range contains special grinding accessories/devices and features a coarse material re-grind system as well as are-blowing machinism. Specific features of the C series are as follows:

  • 1. Ability to grind brittle materials that are prone to over-grinding, producing a "coarse" (d97>140μm), i.e. blow mesh 100) finished product with consistent granule size and even distribution. Suitable for grinding materials such as polyvinyl alcohol (PVA), with more than 80% of the total amount of retention for the neighbouring three sifting numbers (i.e. sifting meshes 40,60 and 80).

  • 2. Has a re-blowing device, suitable for grinding heat sensitive chemical materials (such as PVA), ensuring that their properties will not deteriorat due to the temperature generated during grinding. This reduces the chance of materials forming spheres caused by high speed spinning and fricton-spherical materials are much harder to grind.

  • 3. The granule size of the product is adjustable by adjusting the gaps between the grinding accessories/devices. The machine is capable of grinding both coarse materials (below mesh 100) and fine materials (above mesh 100).

  • 4. Low cost-priced at less than 30% of similar imported machines.
