Pulper Finisher Screen 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. FDA 21 CFR is the reference cited for it on drawings, datasheets and purchase orders.
What FDA 21 CFR Means for Pulper Finisher Screen
The dimensions in the table below are supplied to suit FDA 21 CFR. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.
