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).
Giải pháp: Bột Epic Nhà máy phân loại không khí (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.
