Project Background
With the increasing demand for high-quality powders in the food industry, a large Russian food raw material supplier aimed to process potato starch into ultrafine powder. This transformation was designed to improve solubility, dispersibility, and mouthfeel in pastries, confectionery, and frozen foods. The client’s core goal was to achieve high-efficiency ultrafine potato starch grinding. At the same time, it was essential to ensure uniform particle size and excellent flowability of the final powder.”
Equipment and Process Selection for Ultrafine Potato Starch Grinding
The project adopted the Epic Powder Air Classifier Mill (ACM) as the core grinding equipment.
- Equipment Advantages: The air classifier mill integrates grinding and classification in one system, allowing precise control of powder particle size and ensuring stable particle size distribution.
- Process Parameters: Target powder D97 of 100 μm, with a production capacity of 150–200 kg/h.
Process Workflow
- Raw Material Feeding: Potato starch raw material is evenly fed into the air classifier mill.
- Grinding and Classification: Inside the high-speed rotating mill, the powder is ground through impact and friction, while the built-in air classifier wheel separates ultrafine particles. Coarse powder and larger particles are returned for regrinding.
- Finished Product Collection: Qualified powder is collected through a cyclone separator and pulse dust collector, achieving high-purity, contamination-free ultrafine potato starch powder.
Project Results
- Successfully ground potato starch to D97 = 100 μm with uniform particle size and stable distribution.
- Production capacity reached 150–200 kg/h, meeting the client’s bulk production requirements.
- Powder flowability and dispersibility were significantly improved, providing premium raw materials for pastries, confectionery, and frozen food production.
- The system operates efficiently, energy-saving, with low dust emission and easy maintenance.
