Similar to the BD Series six-component blender, AEC's eight-component blender for its BD-900 and larger blender models offers a riser section below the material hoppers that allows two additional feeders to dispense additive ingredients into the weigh hopper. These feeders are funneled into the weigh hopper with the other six ingredients from the standard slide gate and can process material anywhere between 10 and 2,500 lbs./hr. A 10-in. color, touch-screen controller, which is standard, provides metering accuracy for up to eight ingredients and stores up to 50 recipes.
