Pulper Finisher Screen in 316L Stainless Steel (AISI 316L (1.4404)) is used for separating smooth pulp and juice from seeds, skins and fibers in tomato and fruit pulper-finishers, where rotating paddles force product through a cylindrical perforated screen. The alloy gives superior resistance, including chlorides, brines, food CIP and mild acids and is essentially non-magnetic, with a practical service limit of approx. +550 °C continuous.

Ordering Pulper Finisher Screen in 316L Stainless Steel
- Hole size by stage: 1.2–1.5 mm on the pulper, 0.5–0.8 mm on the finisher.
- Screen size: Diameter and length must match the machine and paddle rotor.
- Alloy: SS316 for acidic tomato and fruit products.
Mistakes to Avoid with Pulper Finisher Screen
- Paddles touching the screen, which tears it.
- Using a finisher screen on the pulper stage, so seeds blind it immediately.
