Introduction for Pregelatinized Starch Production Line
Pregelatinized Starch Production Line adopts professional twin-screw extrusion processing technology, which is the most efficient and energy-saving mainstream production method in the current industrial pregelatinized starch manufacturing field. The core of the whole extruder-based manufacturing system relies on the twin-screw extruder as the key equipment. It completes full physical modification and gelatinization of raw starch through three core conditions: high temperature, high pressure and high shear force inside the machine cavity, without adding any chemical additives. The starch raw material realizes self-heating gelatinization and instantaneous pressure relief puffing and drying in the equipment, and the final finished pregelatinized starch features excellent cold-water soluble performance, stable viscosity and good bonding effect, meeting the dual production needs of food-grade and industrial-grade modified starch.
Working Principle
The advanced extrusion process matched with the Pregelatinized Starch Production Line has unique technological principles and prominent application advantages in actual production. The wet starch raw material with a moisture content controlled at 15%-20% is continuously and stably conveyed into the twin-screw extruder. The strong friction and kneading effect generated during the operation of the equipment will produce internal heat of 120–160℃ inside the machine cavity. The whole gelatinization process does not need external heating and auxiliary heating equipment, which greatly reduces production energy consumption and operating costs. Under the action of high shear and high temperature environment, the crystal structure of starch particles is completely destroyed, and the starch is fully gelatinized in the closed machine cavity to complete the core α-type modification reaction.
Production Flow & Main Equipment
Raw Material Conveying & Mixing: Automatic weighing + water dosing → high-speed mixing (uniform moisture 12–18%).
Twin-Screw Extruder (Core): Alloy screws, self-cleaning design, precise temp/pressure control.
Drying & Cooling: Mesh-belt dryer (moisture ≤10%) → air cooling (prevent caking)
Grinding & Screening: Dust-free hammer mill → vibrating sieve (50–120 mesh).
Automatic Packaging: 25kg/bag weighing & sealing system
Scope of application of Pregelatinized Starch
After the starch material is fully gelatinized, it is extruded out through the die hole under continuous high pressure inside the equipment. The external pressure drops sharply in an instant, and the internal moisture of the material vaporizes rapidly in a short time. The material expands quickly and completes rapid flash drying at the same time, forming a porous and loose physical structure. Subsequently, the materials are processed through professional crushing, fine grinding and vibration screening procedures to obtain high-quality finished pregelatinized starch with uniform fineness and stable quality. Relying on reliable process design and stable equipment operation, the Pregelatinized Starch Production Line realizes fully automated continuous production, with simple operation, few on-site operators and high production efficiency. The produced cold-water soluble pregelatinized starch is widely used in food thickening, building mortar bonding, petroleum drilling fluid, papermaking sizing and feed bonding industries, with strong market applicability and high production economic benefits.
Food: Instant sauces, fillings, meal powders, bakery, and meat products.
Industrial: Oil drilling fluid (fluid loss control), construction mortar (thickener), paper sizing, feed binder.
