AI Technical Summary
Existing methods for manufacturing multichannel tubular filtration membranes face challenges in achieving high production rates and efficient fluid flow, particularly due to the accumulation of liquid in the central zone without a channel, leading to pressure differences and bacterial proliferation, which is unsuitable for the food industry.
A method for extruding a porous tubular support with a multichannel structure using helical punches and a synchronized rotational system to create channels with a limited wall roughness, ensuring efficient fluid flow and preventing liquid accumulation, using a ceramic composition with controlled rheology and sintering.
The method enables high production rates and efficient fluid flow, preventing liquid accumulation and bacterial growth, suitable for applications requiring high mechanical resistance and filtration efficiency.
