A finisher is basically a cylindrical sieving screen. There are two types of finisher (screw-type and paddle)

A- Screw-type finishers: These include a stainless steel screw that convey the pulpy juice through the unit and passes the pulp against cylindrical screen. The juice flows through the screen holes. The pulp is consequently concentrated inside the screen and is discharged at the end of the finisher.

B- Paddle finishers: These incorporate a set of paddles rotating on a central shaft within the cylinder. The pulp is pushed against the screen by the paddles. Paddle finishers apply centrifugal force rather than pressure to separate the pulp from the juice. This usually provides gentler pulp treatment than screw finishers.
