I have a three kettle electric HEMS system that will do fly sparging, batch sparging, or recirculating BIAB. I find myself doing more BIAB as of late. But I have problems with re-circulation where I have to close or turn off the pump to avoid sucking air due to not enough flow through the bag. I have ZERO problems with my regular mash tun recirculating at full speed.
The bag is a standard Voile bag. Doing a lot of reading, this is great for non-recirculating BIAB, but causes problems with re-circulation. There are many partial solutions, grind, rice hulls, etc, but looking through the threads a common theme is getting more flow. 400 micron or larger mesh baskets do not seem to have as much problem, for example.
So anyone know of a fabric that is a little larger hole size? My wife sewed up the current one and used Voile, which appears a little too tight. It appears to be the same material as the commercial bags.
