Cylindrical grinding machine GrindDefine™

digitalPLC-controlledautomatic

Overview
The GrindDefine™ industrial coffee roller mill by Bühler delivers customizable and consistent particle size distributions. Precise roll-gap adjustment and dedicated roll temperature control enable repeatable results for demanding coffee grinding applications.

Key benefits

• Consistent particle size: High-precision gap-setting mechanism ensures accurate roll parallelism and gap control. Touchscreen HMI and process-control software manage recipes and provide full process visibility.
• Advanced roll temperature control: High-performance temperature control with peripheral drill holes maintains preset roll temperatures across production runs to stabilize grind quality.
• Low product residues: Innovative scraper system in the processing zone minimizes residues, speeding product changeovers and reducing waste.

Product features
The GrindDefine™ is engineered for high-precision coffee grinding, supporting applications such as capsule production, instant coffee, filter and espresso and ultrafine grinding. The modular design allows configuration to match product and process requirements.

Wide application range
Modular stages and adjustable parameters — roll gap, roll speed, differential speed and corrugation settings — permit tailored particle size distributions for instant, filter, espresso and ultrafine coffee.

Operational excellence
Designed for continuous 24/7 operation: durable Bühler double-layer centrifugal die-cast rollers are re-corrugatable and long-lived. Roller-package design and extraction device reduce downtime during roller replacement.

Monitoring and control
Recipe-based process control with intuitive HMI: parameters are managed by recipe and continuously monitored. Trend curves and graphical displays enable local or remote operation via touchscreen or control room.

Other features

• Tailor-made particle size distributions: Fine tuning of roll gap, roll speed and corrugation per grinding stage to match target specifications.
• Hygienic design and accessibility: Stainless-steel processing zone with large service doors for fast access, cleaning and maintenance.
• Customized engineering support: Bühler provides configuration, integration and services to align the grinder with customer process requirements.

Application possibilities

• Coffee products: instant, filter, espresso, ultrafine and capsule production
