Modified starch processing equipment
The pregelatinized starch production line uses corn starch, tapioca starch, and potato starch as raw materials. After twin-screw extrusion puffing treatment, it alters the natural properties of starch (such as gelatinization temperature, hot viscosity, freeze-thaw stability, gel strength, film-forming ability, transparency, etc.) to produce a series of products including pregelatinized starch, modified starch, and denatured starch. These are widely used in industries such as briquettes, textiles, food, papermaking, building materials, foundry, and petroleum drilling. The equipment is professionally designed, with adjustable machine cavity and screw structure to diversify the functionality of denatured starch.
The entire line is equipped with a spiral feeder, mixer, twin-screw extruder, air conveyor, cooling bin, grinder, dust collector, grading screen, and packaging machine, featuring a high degree of automation for continuous operation. The series includes five models from DT65-D to DT140-D, with main motors ranging from 22 to 160 kW and production capacities covering 100 kg/h to 2 T/h, meeting the gradient needs from small-scale trials to large-scale industrial production. The company offers equipment selection, process design, formula support, installation and commissioning, and a one-year warranty service.
Pregelatinized starch production line (Datong Machinery) refers to the process of treating raw corn starch, tapioca starch, etc., through extrusion puffing methods to alter their original physical or chemical properties to varying degrees.Pregelatinized starch is a type of modified starch. This equipment has been professionally designed to adjust the machine chamber and screw structure. Pregelatinized starch is a modified starch that diversifies the functions of modified starch. The modified starch series products produced are suitable for fields such as coal briquettes, textiles, food, papermaking, building materials, casting, and petroleum drilling. With further research, the extruder will play an increasingly important role in the modified starch market.The machine consists of a feeding system, extrusion system, rotary cutting system, heating system, transmission system, and cooling system.

Introduction to pregelatinized modified starch processing equipment:
After multiple experiments and production verifications, the modified starch machinery has been professionally designed to adjust the machine cavity and screw structure, thereby diversifying the functions of modified starch. The resulting series of modified starch products are suitable for fields such as textiles, food, papermaking, building materials, casting, and petroleum drilling. With deeper research, the extruder will play an increasingly significant role in the modified starch market.
Main applications of modified starch:
After being processed by an extruder, native starch undergoes varying degrees of change in its original physical or chemical properties. Modified starch is a type of altered starch. To improve starch performance and expand its application range, physical, chemical, or enzymatic treatments are used to introduce new functional groups onto starch molecules or change the molecular size and granular properties of starch, thereby altering its natural characteristics (such as gelatinization temperature, hot viscosity and its stability, freeze-thaw stability, gel strength, film-forming ability, transparency, etc.), making it more suitable for specific application requirements. This type of starch, which undergoes secondary processing to change its properties, is collectively referred to as modified starch. The purpose of modification is, first, to meet the requirements of various industrial applications. For example, high-temperature technology (such as canning sterilization) requires starch with good high-temperature viscosity stability, frozen foods require starch with good freeze-thaw stability, and jelly foods require good transparency and film-forming ability. Second, it aims to develop new uses for starch and expand its application range. Examples include the use of starch in textiles; JYJ starch and JBJ starch as substitutes for plasma; and highly cross-linked starch as a replacement for talcum powder in surgical gloves.
