The Most Trusted Chocolate Refiner

Diamond Custom Machines Corporation (DCM) provides robust tabletop and commercial scale refiners for making chocolate and nut butters from scratch. We are committed to designing machines that are both simple to operate and maintain, and that efficiently and effectively refine cacao nibs and/or nuts to artisan-quality standards.

Additionally, we make it a priority to provide personalized service and support to all of our customers. We provide refiners to chocolate-makers worldwide, and we are proud to support both large scale chocolate making operations as well as small-scale producers who are just starting out (making chocolate directly from their own native crops).


High Quality

Only all-natural, high-quality granite stones are used in all DCM Melangers.



After 12 hours, the machine will have refined the product down to 20 microns, resulting in a grit-free, smooth, and silky texture.


USA Made

Highest-quality, USA-made components and food-grade sealants are used in all DCM Melangers.
