The same thought occurred to me in a dream last night.kzimmer0817 wrote:Thanks for the photos. It helps me figure out how this fits
I'm speaking from no experience whatsoever, but before you hack up your basket: have you operated your kettle, including the recirculating pump, using the bag without the steamer basket? IOW, rig up some kind of false bottom (the broccoli steamer as I've seen before) in the bottom to make certain that it's the basket that's slowing down the flow and not simply the bag.
Once I hit temp, I don't believe I need any flow to maintain temp (there is a lot of thermal mass I'm working with). I just wanted to skip the insulating thing and use "technology".....sometimes simpler really is better. I believe just tossing the lid on and throwing a blanket over the rig would do the job. If temps did drop significantly I could always fire up the heat and recirculate for a few minutes.kzimmer0817 wrote:Also, how fast do you need the water flow to be in order to maintain your temps? I wouldn't think it would be much (again, just pondering it without having experienced it). In your photo, there are 2 rows of holes above the level of your grain, so I don't understand how that many unobstructed holes won't allow your flow to drain out and around the basket rapidly enough to keep the kettle from overfilling unless it's the bag that's causing the most resistance.
See my first comment, above. I did a lot of "daydream engineering" too but I can attest that what happens in the real world doesn't always conform to the engineering manuals in my headkzimmer0817 wrote:I've been "imagining" and "designing" my own build in my head even before seeing your great idea. I had wondered about trying to find a correctly sized wire basket (like those in used to make french fries in the deep fat fryers) what would be more "hole" and less "metal". Sort of like one of these if you could find one deeper.

I thought very hard about where to put the probe, there are pro's and con's to putting it just about anywhere. I searched for a water-proof probe to no avail, finally decided that since heat rises I would put it as low as possible to avoid having the lower column of liquid become over-heated in an effort to reach a set temperature at the top of the liquid column.kzimmer0817 wrote:Is it possible that this might be due to the location of your temp probe - in the space underneath the basket and near the heating element? If the probe were stuck into your mash, might it work better? It's possible that I'm not fully understanding the process - not knowing if it's a problem with how the PID functions or a problem with sensing the temp.
The thing drains VERY slowly through the basket, I ended up ditching the basket after mashing, hanging the bag, and squeezing the heck out of it (like I usually do). Wanna buy a basket?kzimmer0817 wrote:How fast did the bag/basket combo drain when you raised it compared to when you did BIAB without the basket? I'm just trying to save you the trouble of hacking up your basket (which isn't a cheap piece of equipment when purchased separately).
It is likely that crushing your grain a little finer will further impede the flow of wort thru the bag itself as well as the basket. I still wonder if slowing the flow in your recirculator would solve the issue without having to cut up your basket.
I appreciate your questions and feedback, polycephaly is a wonderful advantage when designing/engineering.kzimmer0817 wrote:Respectfully submitted,

While I do like the idea of some type of basket as a supporting framework for the bag, in the end it just becomes an impediment to the flow of liquid out of the bag.
There is a thread over at Homebrewtalk.com where ScubaSteve tried all sorts of different size stainless steel mesh in order to make a basket. The biggest issue is cleaning: the grain husks stick in the holes of the mesh and it is a real bear to clean. Last I heard he was throwing in the towel and going back to using a bag (there's that K.I.S.S. thing again).
I don't think I'm going to jump onto this house. It's elegant, but it'll be well over my budget after I add the garage/shop - "if" I can get that past the Homeowner's Association's Architecture Committee. Thanks for asking.Here's hoping that you find a nice house with a 20' x 20' stand-alone shed that is also equipped with water, electric, and a floor drain.

I've googled for several different key word combinations and can't find anything already built. The smallest hoist/trolley lifts about 1/2 ton. So, I guess I'll have to design something myself.
datamichael, I've read about that, but I have a question about its applicability here. Will the rice hulls automatically sink to the bottom? Since Todd is stirring his mash in addition to recirculating, wouldn't the rice get mixed up in the grain thereby allowing grain to clog the mesh? I can see how it would help in an unstirred situation such as a mash tun. How has it been working for you?I've been experimenting with a similar "basket" system. More holes definitely increases flow. A simple fix if you're having problems though, is to toss in a pound or so of rice hulls. I used them in every batch with my 3-vessel system, and also use them with my BIAB/bucket experiments.

Anyway, gotta get going - about 45 minutes away to practice the organ for a wedding that I'm playing for in 2 weeks. When I get home, I'm going to try to bottle up the American Wheat beer - extract kit I brewed 2 weeks ago. The O.G. was 1.043. Yesterday (day 15) it was 1.014. There has been no bubbling for several days.
Later,

This is great news for me. Dunno exactly why, but I was pretty excited about the idea of using a basket to support the bag, and your earlier posting got me a little depressed. Glad it works much better now with the Swiss cheese modification - although, as was suggested, it would have made for a lovely lantern.thughes wrote:The Swiss cheese modification to the basket seems to have improved the process. I can now crank up the recirculation and the temperature is staying rock-solid. No signs of draining restriction, liquid level is remaining stable now that the basket can flow better. The final test will be how well it drains when I hoist it out.
