Hear What Our Customers are Saying
Drew and the Diamond America team worked quickly to replace our overheating extruder. We sent two shipments of dough for lab testing – one for proof of concept to extrude the desired shape and one for a custom feeder designed to continuously extruder sticky dough. Diamond America quickly shipped the extruder and designed the feeder. After ongoing collaboration and a few modifications, the final design was approved. As a result, the material fed more efficiently and continuously without sticking and without overheating. In addition to their responsiveness, professional work, and innovative hopper design, I would highly recommend Diamond America.
