Pre Gelatinized Starch Extrusion Machine

Pre gelatinized starch is a type of modified starch that is easy to process and widely used. When applied, it only needs to be mixed with cold water to form a paste, eliminating the trouble of heating and gelatinization. Widely used in many industries such as medicine, food, cosmetics, feed, oil drilling, metal casting, textile, papermaking, etc.

Pre gelatinized starch extrusion machine: This is a method of producing pre gelatinized starch using a spiral extrusion puffing machine based on the principle of extrusion puffing. Add pre adjusted wet starch with a moisture content of 15-20% into an extrusion extruder. The starch is heated and gelatinized by friction and extrusion with a screw shaft, and then extruded under high pressure through small holes with a diameter of 1-10 millimeters. Once the material enters the atmosphere, it instantly expands and dries, and is crushed and screened to obtain pre gelatinized starch. Due to the high shear force, the viscosity of the product decreases and its solubility is higher than that of the drum method product. Due to the minimal need for water addition during the manufacturing process, internal friction heat can be used to maintain a temperature of 120-160 ℃, and no heat source is required for drying. This Pre gelatinized starch extrusion machine has the characteristics of low equipment investment and low power consumption.
