So recently, I moved from BIAB to a 48 qrt cooler as a mash tun with a stainless 3/4" braided hose, and batch sparging. Think after about 4 batches now that I've got my numbers pretty well dialed in. The one problem I am experiencing is the runoff. I've got a stainless 1/2" valve fitted with a 1/2" barb and 1/2" silicone hose. I try to start the vorlauf slow to allow the bed to settle and run off till clear. I slowly start opening the valve and continue. Runoff seems slow once I start going. The 1/2" hose never fills up and does a really nice flow like I think it should. On my last brew, I was getting a slow steady stream on my sparge and everything was going nice, then a large 'burp' in the line and all of a sudden I had full flow! Bad part is, some of that wort coming so fast wasn't exactly clear any longer because of the sudden surge. I can work past that part, I guess my question is, am I missing something on the runoff process? I've searched around and haven't really seen anyone mentioning this. It was like a large gurgle and then nice flow although no longer clear. Is there a possibility the hose size is too large for the runoff? Not allowing to fill to proper level to pull properly?
Prior to brewing, I did check for obstruction in valve and braided hose, so no clogs. My current thoughts are a clamp on the silicone tubing downstream from the valve, or possibly moving to a smaller outlet barb on the valve and smaller line.
