C, in drainage process, controller calculates this time drainage in real time and originates to the current real-time drainage flow of single achieved, After the real-time drainage flow of single reaches preset single drainage flow, controller will make cam stop rotating, and this time drainage is tied at this time Beam and at this time drainage tube still keep off state by static roll pressed, that is, realize quantitative drainage.
