OPTIMUS COFFEE GRINDING ROLLER MILL
(5th GENERATION)

PLC-controlled smart coffee-grinding station with cooling system

A next-generation cylindrical breaking-and-crushing unit for grinding roasted coffee beans without aroma loss, to a targeted micron-level size and with flawless particle distribution in industrial coffee-processing plants. Unlike traditional disc mills, the OPTIMUS Coffee Roller Mill processes coffee without heating it and preserving its volatile oils, offering maximum homogeneity for Turkish-coffee, espresso, filter-coffee and soluble-coffee processes.

WORKING PRINCIPLE

Precise load cells and feed automation — aroma-safe level management: roasted beans entering the top hopper are weighed instantly by high-precision load cells; the PLC feed unit delivers the product between the rolls in a single ribbon across the full width so as not to break the beans prematurely.
Cryogenically treated, water-cooled rolls — temperature-controlled grinding: to keep the coffee from heating and losing aroma, water-cooled rolls with a special cooling jacket — through which cold water circulates — engage; the beans are crushed and broken under controlled temperature.
Multi-stage differential fluting geometry — micronised breaking: special-alloy fluted rolls rotating at set speeds and differential ratios bring the coffee to its exact micron size without dusting, while the sealed anodised body completely prevents the escape of coffee dust and volatile aromas.

KEY ADVANTAGES

• Zero aroma loss (Cool-Grinding technology): Mechanical heat during grinding can burn the coffee’s volatile oils and create a bitter profile; the integrated-cooling rolls keep process temperature stable, letting the coffee be produced at its original room temperature in its freshest state.

• Precise particle size (particle) control: Per the micron value entered on the PLC screen, the gap between the rolls (gap control) is set automatically by servo motors; the homogeneity needed for espresso and the coarseness needed for filter coffee are achieved without deviation.

• Fast roll change (Cartridge-System): The fully opening front cover allows the rolls — whose fluting profile must change for different coffee types — to be removed and replaced practically as a single “pack/cartridge”.

• Silent, antistatic timing-belt drive: The gearbox-free timing-belt drive fully eliminates the risk of oil leakage, while the antistatic internal coating keeps fine coffee dust from sticking to and building up on the body through static.

• Coffee-diagram application matrix: Turkish coffee / espresso: ultra-fine fluting, narrow gap — precise crushing and micronised breaking give a homogeneous extraction surface without dusting; filter / filter-press: medium/coarse fluting, wide gap — stepped granulation with a minimum fines ratio for clear brewing.

ENGINEERING NOTE

The OPTIMUS Coffee Roller Mill is designed to trap the carbon dioxide and volatile aromatic oils inside the coffee bean without destroying its cellular structure. High gap stability ensures the balance of crema, body and acidity in the cup stays standard from cup to cup, even after the coffee has been packaged.
