I. Introduction of Modified Starch-Based Buffer Material

The starch-based buffer material is made of the degradable natural starch or modified starch as the basic raw material, optionally with other auxiliary ingredients. It is produced by screw extrusion molding process. Starch-based buffer materials are degradable, antistatic and inexpensive to produce, making them an excellent alternative to traditional petroleum-based plastic cushioning materials.

IV. The General Flow Chart for Starch-Based Buffer Material

• चरण 1: मिश्रण
• Step 2: Extrusion (With heating and cooling function)
• Step 3: Drying
• Step 4: Measuring and packing

Modified Starch-based buffer material making machine work process is as follow:

1) Raw starch (one or a combination of corn/rice/wheat/cassava starch, or the corresponding modified starch) is mixed with a certain amount of water evenly. The water content is usually 14-20%. 2) Other auxiliary materials such as corn fiber, straw powder or high molecular polymers can also be added to prepare buffer materials with different characteristics. 3) The material is gelatinized under the correct temperature, pressure and shear force in the twin-screw starch extruder. 4) The gelatinized startch is extruded through a die. Due to the pressure and temperature difference between the inside and outside of the screw, the moisture in the extruded product evaporates rapidly, and the extruded product rapidly expands into a foam-like material with the required density and elasticity. 5) Then, the puffed granules are dried to optimize the moisture content.

Only a small amount of water is added during the whole production process, and the temperature of 120-160°C can be maintained by using internal frictional heat. However, when with different extrusion temperatures, different starch raw materials have different expansion degrees or densities. Therefore, the starch extruder barrel is usually equipped with cooling and heating zones to achieve precise temperature control to meet diversified production demands.

लचीलापन

• Wide raw material: The screw starch extrusion method is suitable for a variety of natural or modified starches, and the raw materials are rich in sources, including grain starches like corn starch, rice starch, wheat starch, and root starches like tapioca starch. It is also suitable for various auxiliary materials such as corn fiber, wood flour, vegetable oil, seaweed, etc. Natural or artificial colors can also be added to obtain different colored finished products.
• Various texture: Process parameters (temperature, pressure, screw speed, etc.) can be flexibly set to match different starch raw materials and different expansion requirements, so as to produce starch-based buffer materials with required textures and characteristics for different shockproof demands.
• Shapes: Different extrusion dies can be configured to produce cushioning materials of different shapes and sizes, such as spheres, cylinders, ellipsoids, irregular bodies, particles, etc.

Potentiality

• If add a set of pulse crushing device, this modified starch buffer making machine can also produce various pregelatinized स्टार्च, including food grade, construction material grade, fragrance grade, briquet grade, petroleum grade, feed grade, medical grade and other pregelatinized starches.
