Modified Starch Process Line – The Best Choice for Large and Small Enterprises
On the basis of natural starch, the intrinsic characteristics of modified starch in order to improve the performance of starch and enlarge its application scope by use of physical, chemical or enzymatic treatment, the introduction of new functional groups on the starch molecules or change the size of starch molecules and the characteristics of the starch granules, and then transform the natural properties of the starch pasting temperature (such as: hot viscosity and its stability, freeze-thaw stability, gel strength, film forming, transparency, etc.), these changes will make it more suitable for a certain application requirements. This type of starch, which has been subjected to secondary processing and changed properties, is collectively referred to as modified starch.
Modified starch is designed to apply the requirements of various industrial applications. For example, high temperature technology (canned sterilization) requires viscosity stability of starch in high temperature, frozen food requires good freeze-thaw stability of starch, jelly food requires good transparency and good film formation. The second is to open up new applications for starch and expand the scope of application. Such us starch is used in textiles, hydroxyethyl starch and hydroxypropyl starch are used instead of plasma; high cross-linked starch is used instead of talcum powder for surgical gloves.
The development of modified starch in China started late, in the 1980s. It has been applied in many fields, such as textile, paper, food, feed, foundry, medicine, construction, and petroleum. The application of modified starch in China is still an emerging business, no matter from the type, quality, or application range of modified starch, it is quite different from foreign countries. Only from the type of modified starch, more than 2,000 kinds of modified starch products have been developed and exported in abroad, including oxidized starch, acid modified starch, starch ester, starch ether, crosslinked starch, cationic starch, grafted starch, and ring dextrin, white dextrin, pre-gelatinized starch (pregelatinized starch), dialdehyde starch and etc., of which more than 200 modified starches are produced from corn starch, but there are only about ten varieties of starch in China.
If according to calculated the amount of modified starch used in various industries in China, the annual demand is between 1 and 2 million tons. Nowadays, the application prospect of modified starch is very broad. If increase its research, application and promotion in this field, the production of modified starch will have rapid development.
Our pre-gelatinized starch/modified starch line is specifically designed to produce a wide range of modified starches, such as modified starches, pre-gelatinized starches. This process line was developed on the basis of ourselves and study of foreign advanced technology, and its technical performance and product quality reached the world's most advanced level. This is an advanced puffing machine with flexible collocation, extensive applied raw materials, easy operation and suitable for use in small factories.
