Presentation
The PRO100 micro-milling unit is a stone mill designed to produce up to 85 kg of flour per hour. Fitted with 100 cm natural granite millstones and an integrated bolter (sifter), it delivers a gentle milling process that preserves nutritional and organoleptic properties of cereals, legumes and tubers. The PRO100 can operate as a standalone unit or be pooled to increase production capacity.

Function

• Production of flour up to 85 kg/h (average output; single-pass extraction 84 %).

Application

• Annual production 60 to 300 tonnes of flour — modular stone-mill unit suited to farmers, small mills, food labs and millers.

Benefits

• Digital control of milling parameters for repeatable settings.
• Ergonomic operation and precise micrometric adjustments adapted to team workflows.
• Preservation of germ and protein fractions for terroir-style flours.

Who / Why
Agricultural producers — complete micro-milling solution to process and valorise cereals at scale.
Food laboratories / Research / Millers — precision tool ensuring repeatability of milling parameters and facilitating team work.
Small mills — solution to develop specific stone-milled flour ranges.

Operation principles
Gravity feed or pneumatic transfer to the mill; adjustable millstone speed for controlled milling (50–120 rpm); post-milling bolting/sieving separating flour, semolina and bran; ergonomic storage options (hopper up to 1000 L or sequential loading ramp). Temperature of flour is monitored and machine stops on over-temperature setpoint.
