For the copper: looking at http://www.toledometalspinning.com/shop/prefab-conical-hoppers-304/14.7conical-hopper-304-stainless-steel/ with the standard top, http://www.toledometalspinning.com/shop/lids/lid-for-standard-20-conical-hopper-x-304ss/

Simpler might be better. I am going to glue the following parts together and be done with the design. Want to get my conical copper/settling tank done after this one. Components and planned unit for case sizing. Next step 1) flip the connecters on the xmega-A3BU xplained 2) mount...

This thread is to document my design /build of a conical Electric Copper and Settling vessel. After reading Brewing Science and Practice I have decide have the following options. 1) Conical Settling tank 2) pump to recirculate during boil (return to scatter cone) 3) ability to control...

Here is the link: https://www.homebrewtalk.com/f51/simple-digital-brew-thermometer-control-out-295021/ The parts for the WiFi device is still the AVR MEGA XPLAINED, + the WiFI board, but I am going to shoot for a low cost (no OptoIsolator) build first. Joel

Today I brewed a English ale, 6.25lbs, mashed with 1.75 qt/lb water to grist. The following ramp are observed (using 2 elements) in 54 degree F ambient air temp. 10:46am 116F 10:47am 117F 10:48am 118F 10:49am 119F 10:59am 132F ---- Working fine, so I stopped recording. The attached photos...

Just a post to bring up this link. There are a number of threads of people discussing issues with RIMS and HERMS, so I thought people might want to follow this thread. It works, and for 5 to 10 gallons in a well insulated system, it works very well. I hope to post the step by step for a...

I documented it here: https://www.homebrewtalk.com/f51/electric-heating-element-rims-eherms-293810/ I am doing a couple of cycles this weekend so I will take photos to document the process. Joel

I agree. The thing I didn't like about the element in the RIMS tube is the potential modes of failure. For example, if fluid flow stops. If the entire system is insulated well, and there is turbulent flow down the pipe, the temp gain of the fluid through the length of the heated pipe for a...

I do ramps using heat tape outside of a rims tube with no issues.

Here is a heat loss calculator: http://www.thermalinc.com/math/aitkenform.htm I did a 5'x5'x5' cube, and 0 outside temp. with a design temp of 50 degrees and came up with about 50 watts being required to maintain temp. For example a light bulb. It really depends on fast you want to...

I have some success using the following approach: A Heat-tape based RIMS/HERMS tube. There is no hot electric heating element in direct contact with the mash liquid, rather heat tape is applied to the outside of a stainless steel pipe. A significant rework, but it is really low density.

I was running with two units for most of the time. In the beginning, over two years ago, I did use only one pipe, but observed < 0.25 degree rise per minute. I then added the second tube and insulated. I think insulation made a huge difference, and you might be able to get away with...

Here is the diagram Joel

All the parts and build photos are a few posts back. The heater is wired in just like the RIMS tube, with a Solid State Relay controlling the power the heat tape. I put a thermal fuse in the box with the heaters just to be safe, these go inline with the power. I will post a diagram in...

Sorry, work has been getting in the way. I do have to adjust my priorities :-) It increased the ramp, by about 1/2 to 1 degree. It is a bit hard to judge, because the losses in the system depends on the surrounding temp. But, the rate of increase by adding the spring was significant!! I...

Thanks. That is what I thought as well.

All, I chatted with someone who is majoring in bio-chem, and I don't understand why we want > 1 degree F per minute increase in the mash temp. Everything I have been reading seems to indicate that it is the temp*time rather than the time which is important. Joel

Finished two the mashes today, 12# and 13# of grains. System did between 1 degree F/minute and 1.25 degrees a minute. Outside temp started at 41F and at the end 50F. 1 to 1.5 degrees/min. System ramps from mashing to mashout in < 15minutes. I must admit, once the mashing is done, I set...

I put a length of stainless steel rod and a spring over the rod in the lower heating pipe and I am currently mashing 12 lbs of grains, with 1.25 qts/lb. The ambient (outside) temp is 41 degrees Fahrenheit and with the modifications in one of the heating pipes I am getting >1 degree/minute rise...

This weekend I am running two batches through the system. I am putting in the following (see below) to introduce turbulence into the flow and increase heat transfer. I will try the stainless steel rod in the center of the pipe on one five gallon batch and record the rate of temp increase...
