Customer Background
As one of the world’s major grain-producing countries, Kazakhstan is home to a food company dedicated to developing high-quality meal replacement powders and instant roasted barley tea products. Roasted barley ultrafine grinding was required to process roasted whole-grain barley into an ultrafine powder, ensuring excellent suspension in water or milk and a smooth, silky mouthfeel.
Core Challenges
- High fiber content: Barley husks are rich in tough fibers. Conventional grinding equipment finds it difficult to fully micronize them, often resulting in a coarse texture.
- Oil content and temperature control: Roasted barley contains small amounts of natural oils and a rich aroma. Excessive temperature rise during grinding can cause oil exudation, clogging screens and leading to aroma loss.
- Balance between fineness and capacity: While maintaining a throughput of 100 kg/h, the system must achieve an ultrafine specification of D90: 45 μm (approximately 325 mesh).
Solution: Episch poeder Luchtklasseermolen (ACM Series)
Based on the physical characteristics of roasted barley, Epic Powder recommended the ACM Series Air Classifier Mill. This equipment integrates high-speed impact grinding with precise air classification, making it an ideal choice for ultrafine grinding in the food industry.
1. Technical Highlights of the Roasted Barley Ultrafine Grinding System
- Efficient shearing and impact: The high-speed rotor works together with the toothed liner to instantly break down barley fibers through high-frequency shear forces, effectively eliminating fiber residue issues.
- Built-in precision classification system: The machine integrates a dynamic classifier wheel. Qualified powder with a particle size of 45 μm is carried out by the airflow, while oversized particles are automatically returned to the grinding zone. This closed-loop circulation ensures extremely uniform particle size distribution.
- Low-temperature processing environment: The large airflow generated during grinding provides a natural cooling effect, perfectly preserving the distinctive roasted aroma of barley.
- Easy-to-clean design: To meet food safety requirements, the mill features a quick-opening structure, allowing thorough internal cleaning and sanitization.
