Take Control of Your Roast with the Pearl Mini

If you’ve ever spent an afternoon hand-sorting coffee, you know how draining it can be. The pile never seems to shrink, your eyes start to blur, and the thought of roasting gets pushed further down the day. Yet every bag you put out still has to be consistent. That’s what your customers expect, and what your reputation depends on.

The Pearl Mini was built to take that weight off your shoulders. It’s a compact coffee color sorter designed for roasteries that care about detail but can’t afford to waste hours on repetitive work.

Why consistency is so hard to keep

Specialty coffee rewards precision. Prices keep rising, margins keep shrinking, and yet quality has to hold steady—or better. Quakers, burnt beans, or a few missed stones can undo hours of effort. One cup that tastes “off” can feel like it cancels the dozens that came out right.

Hand-sorting might work at small volumes, but once your business grows, it becomes nearly impossible. Instead of roasting, training staff, or connecting with wholesale partners, too much of the day gets lost picking through beans.

How the Pearl Mini changes the workflow

The Pearl Mini uses dual 4K cameras to scan each bean, capturing over 500 images every second. Defects are detected and removed with precision, which helps reduce waste and safeguard quality.

It’s designed for roasteries running 15–70 kg machines, with throughput of up to 250 kg of roasted coffee per hour or 500 kg of green. That means it’s powerful enough to keep pace with production demands while compact enough to fit into most roastery layouts.

Why it matters

At the end of the day, customers don’t see the hours you spend sorting. They only taste what’s in the cup. The Pearl Mini keeps the tedious work in the background so you can focus on the craft—and the quality—that sets your coffee apart.
