Gelatinized starch, a colloidal substance formed by heating starch and triggering gelatinization, is widely used in various industries due to its high hot paste viscosity, low specific gravity, strong film-forming properties, and excellent water absorption and expansion. It plays a crucial role as a thickener and stabilizer in the food industry, as an adhesive and surface sizing agent in papermaking, and as an excipient or disintegrant in pharmaceuticals.
Sieving Requirements
- Purpose: Grading, impurity removal
- Mesh size: 100 mesh
- Capacity: 1–3 tons/hour
- Recommended Equipment: Airflow sieve, tumbler screen, ultrasonic vibrating screen
Challenges in Sieving
Gelatinized starch is sticky and has low flowability, which often leads to agglomeration, clogging of mesh openings, reduced capacity, and interrupted production. In many starch processing lines, inefficient sieving becomes the primary bottleneck.
Our Sieving Solutions
We recommend the airflow sieve, specifically designed for fine, sticky powders. Its airflow-assisted dispersion effectively reduces mesh blockage and material buildup, ensuring continuous operation and high throughput.
For higher capacity needs, we suggest upgrading to a tumbler screen or ultrasonic vibrating sieve, or using multiple machines in parallel. Combined with optimized raw material ratios, this approach can eliminate bottlenecks and significantly improve product quality and production efficiency.
Let us help you streamline your starch sieving process with tailored equipment and expert solutions.
