Earlier this year I built a custom sculpture and quickly thereafter I realized I needed to add a RIMS system due to the size of the batches. I'm pretty sure I have the idea and design down for the RIMS system, but I am unsure of one part. After the wort leaves the heating element and goes back into the mash how is it dispersed evenly over the top of the grain bed. Is it just a single hose laying on top of the bed or is there a disperser, like a shower head, that evenly lays it across the top of the grain bed?
