A small two- to four-component gravimetric blender can process 10 to 150 lb/hr and has a stainless-steel hopper and mixer bowl. Model 150 is the latest addition to the SGBD Series gravimetric blenders from Sterling Inc., New Berlin, Wis. While small, the unit is said to be just as tough as its larger predecessors, SGBD 450, 900 and 2500. Like all SGBD blenders, it features a removable weigh hopper for quick color changes. An adjustable slide gate stroke limiter provides accurate metering of minor ingredients. It comes with an Allen-Bradley PLC and PanelView 500 touchscreen interface that stores up to 50 recipes.
