CAFEC Two-side Crepe Technology
The drying process of a 2-side crepe CAFEC paper filter differs from the making of traditional paper filters. The 2-side crepe filters are air-dried horizontally, retaining crepes on both side of the paper. The traditional rotary hot drum drying method applies pressure and flattens the bottom side of the crepe, creating a flat surface on one side.
Additionally, the finer texture of a CAFEC filter enables water to flow smoothly with stability for a more controllable extraction process.
