COMMERCIAL CHOCOLATE MAKING MACHINE LOW-IMPACT REFINERS FOR BEAN-TO-BAR AND NUT-TO-SPREAD MAKERS At Diamond Custom Machines, our innovative engineering is focused on manufacturing quality, low-impact refiners for making fine chocolate, nut, and seed butters. Low-impact processing allows for optimal retention of nutritional value and at the same time prolongs shelf-life. Our machines are easy-to-use and highly reliable, thus maximizing production while minimizing downtime. In designing our machines, we partner with established artisans in order to better understand what they look for in a refiner and to design with those needs in mind. We consistently hear that users want a machine that is simple to operate, low in maintenance that is backed up by top-notch, highly responsive customer service. We strive each day to meet those expectations. All DCM large capacity refiners are constructed the same way using the same high-quality materials. The main differences between the models are the size and capacity.
