Advanced Wet Process Modified Starch Production Machinery

Product Description
In order to improve the properties of starch and expand its application range, physical, chemical or enzymatic treatments are used to introduce new functional groups on starch molecules or to change the size of starch molecules and properties of starch granules, thereby changing the natural characteristics of starch (such as gelatinization temperature , Thermal viscosity and its stability, freeze-thaw stability, gel strength, film-forming properties, transparency, etc.), making it more suitable for certain application requirements. This kind of modified starch is called modified starch after secondary processing.
Process Flow Diaagram

Process Description:
(1) Pre-gelatinize Reaction: Send the refined starch to the buffer tank to get the qualified DS and PH, then is sent to the reaction tank. Reaction is the key working procedure in modified starch production. Add some chemicals into the measured starch milk according to reaction requirement and heat it to suitable temperature (40-50ºC)generally to make the starch and chemicals react. In order to control reaction temperature in a certain degree, it needs to cool the reactant. The reaction time which is on the basis of variety requires 3-24 hours commonly. After the reaction, it will be ceased by adjusting PH value.
(2) Washing: It is necessary to wash the reactants because of some not-full reacting chemicals and some deleterious impurity inborn from reaction. Different product variety should adopt different washing technique and equipment, normally cyclone or screen washing is needed which needs 4-6 step washing and get the qualified modified starch.
(3) Dewatering: The fine modified starch after washing needs dewatering to get the qualified water content in the starch milk. Centrifuge equipment is needed for this function.
(4) Drying and Packing: The modified starch is dried by air flow dryer. In accordance with the granularity demanded by the product, the un-qualified coarse starch in the drying system should be crushed to the qualified starch. Finally the products can not be packed until they meet the demand. Then it will be packed by 25Kg /sack in manual or mechanical.
