Pregelatinized Starch Machine

                                                      Pregelatinized Starch Machine

The extruder modified starch production line is an efficient and continuous physical modified starch production system that integrates conveying, mixing, reaction, shearing, steaming, forming, and cutting. It utilizes the unique environment of high temperature, high pressure, and high shear provided by twin-screw extruders to complete various denaturation reactions of starch in a very short time, which is an important development direction of modern starch modification technology.

1, Core working principle
The core is to use a twin-screw extruder as a reactor. After the starch raw material (original starch or material mixed with chemicals) is fed into the extruder, it undergoes the following process under the push of two interlocking rotating screws in the same direction:
Conveying and mixing zone: The material is conveyed forward by the screw and thoroughly mixed with added chemical reagents (such as acids, bases, esterification agents, etherification agents, etc.) or water.
Compression and reaction zone: The material enters the kneading block and shear element area, and is subjected to enormous mechanical shear force and frictional heat. At the same time, the external heating of the barrel rapidly increases the temperature of the material (usually between 120-180 ° C) and the pressure. Under these conditions, the structure of starch granules is disrupted, and chemical reactions such as hydrolysis, cross-linking, esterification, and etherification are dramatically accelerated, completing the denaturation process that would take several hours or even tens of hours in traditional kettle style in a very short time (usually tens of seconds to minutes).
Steaming and homogenization zone: During this stage, starch is completely gelatinized and melted into a uniform fluid.
Extrusion and Forming Cutting Zone: The denatured and gelatinized starch melt is extruded through specific holes on the mold plate under high pressure and immediately cut into short strips, granules, or small pieces by a rotating cutter.

Mixer flour

Vertical powder mixer, also known as vertical mixer or V-shaped mixer (specific type), is an efficient powder mixing equipment widely used in industries such as food, pharmaceuticals, chemicals, feed, plastics, etc. Its core characteristics are mild mixing, no dead corners, and minimal damage to material particles, especially suitable for mixing powder or small granular materials with similar specific gravity and good flowability.

Double-screw extruder

Twin screw extruder is an efficient and continuous mechanical processing equipment that integrates conveying, mixing, shearing, heating, reaction, cooking, and forming.
Its core lies in the complex interaction between two screws that mesh with each other, rotate in the same or opposite direction, and exert strong shear, compression, and mixing effects on the material inside the sleeve.
It is far more than just a 'machine', but a complete multifunctional process platform.

Dryer Oven machine

Mesh belt drying equipment, also known as belt dryer, is a continuous drying equipment that uses a mesh conveyor belt to carry materials, moves continuously inside the equipment, and comes into contact with hot air to achieve uniform drying. It is an ideal choice for large-scale, continuous drying operations, especially widely used in dehydrated vegetables, fruits, traditional Chinese medicine, feed, fertilizers and other fields.

Pulse grinder

A crushing unit is a system used in industrial production to mechanically crush and grind large solid materials into powder of the required fineness. It is far more than just a shredder, but a complete system composed of multiple devices working together.
