The installation hardware mainly consists of four parts: 1) masking units, 2) vacuuming units, 3) a screening mesh unit, 4) a blowing unit. The masking units are mechanical structures(four 7-segments and one colon) driven by servos that open or close their segment-shaped holes where air flows. The vacuuming units have fans on the back generate negative pneumatic pressure that suck air and grains in the chamber. The screening unit is a mesh fabric where the grains are collected. Only air can pass through it, but Styrofoam grains can not. The blowing unit has 9 pairs of fans at the bottom and top to below up Styrofoam grains in a vertical direction, and 3 pairs at the left and right side to blow away grains in a horizontal direction.
