Grain Sorting? Grenat.
Meet our Swiss made
high‑precision, AI‑powered
optical sorting machine
designed for small batches
and alternative crops. 🌱
Swiss precision.
Built for farmers.
Grenat enables farmers and
cooperatives to process grains locally,
autonomously, and profitably.
The machine uses high‑resolution cameras and AI to inspect each grain on a controlled conveyor, removing stones, foreign materials, defective grains, and other unwanted materials in real time. Designed for complex grains, it delivers high‑precision sorting for small batches and alternative crops such as lentils, millets and more.
Precision of 100%
Recall of 99.6%
Throughput of
150-500kg/h

Building with purpose.
Most optical sorting machines are designed for industrial‑scale production, leaving some farmers without adapted solutions for smaller batches and alternative crops. As these crops regain in popularity worldwide, especially in Africa and Asia, a real need has appeared.
Grenat exists to restore autonomy at the farm level by enabling precise and local sorting. By supporting regenerative practices and resilient crop systems, we contribute to a more sustainable and equitable food system.
With Grenat, we directly target four Sustainable Development Goals set by the United Nations:
A long-term vision.
Our ambition goes beyond a standalone optical sorter. We are building a modular, connected system designed to integrate seamlessly into your workflow.
A dedicated app will further enhance your autonomy, allowing you to monitor and manage your machine when you are working elsewhere in your farm.
