The types of equipment used and the flow design of the plant is .

 · Balzan said that the third revision is seeing the FP 2000's washing system being moved from the side of the filter press to the top, where the robot is loed, automatising the washing process. "When you wash something, you should start from the top. This change also eliminates for operators a dangerous process at the side of the machine.
