FRF II Fine Refiner
Next-generation Fine Refiner for processing chocolate, compound or cream
Built to solve. Designed to deliver.
The Heidenauer FRF II Fine Refiner is a next generation, fully automatic five roll refiner designed for chocolate manufacturers who combine a preference for traditional refining technology with the need for modern performance and efficiency. Engineered for high throughput, consistent product quality, and seamless integration into existing lines, it meets the demands of today’s high capacity, line based chocolate production environments.
During refining, the viscous product passes through counter rotating rolls with progressively increasing speeds, achieving precise particle size reduction with each pass. Continuous operation is ensured by the Stripe Detection Cockpit and automated fineness control, delivering stable quality, high throughput, and operational safety.
Optimized for space constrained environments, the FRF II combines a compact footprint with an output of up to 1.5 t/h, allowing multiple units to be installed in line to increase overall plant capacity while maximizing floor space utilization. Requirement based drive design ensures balanced, energy efficient operation, while refining cycle times reduced by up to 40% lower overall operating time and energy consumption.
Fully compliant with the 1800 industry standard, the FRF II integrates seamlessly into existing grinding and refining lines, enabling easy retrofitting or capacity expansion with minimal disruption. Equipped with Super Rolls, the FRF 1500 II increases throughput by up to 30%, enabling faster conche filling and shorter cycle times, without increasing the footprint.
A hygienic all angle design with easy rear access, raised machine construction, and enclosed drive concepts supports fast cleaning, reduced contamination risk, and consistently high product quality.
The Heidenauer FRF II delivers all the advantages of traditional five roll refining without compromise on efficiency, footprint, or scalability. It is the ideal solution for modern, performance driven chocolate production.
