Discussion History

Control System

Assembly

A PLC runs the freeze, primary drying, and secondary drying steps automatically, holding shelf temperature and chamber pressure on a recipe and watching product probes so the run ends only when the product is dry. It logs every batch. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
