I'm coming from a 3-piece all grain setup, so I'm used to a normal mash tun with the false bottom. Everything on the Robobrew makes sense to me except that little center pipe. What's the purpose of this, and the stainless funnel piece that sits on top? Wouldn't the malt pipe work just fine if it were capped off, leaving just the malt pipe with a screen on the bottom?

So it sounds like a safety measure to prevent no wort in the kettle while the burners are on. Makes sense if you're recirculating the mash and leaving it unattended.
Just saw this comment:
One word of caution on plugging the center pipe, if you end up with a truly stuck recirculating mash, you could end up dry firing the element and causing a potentially bigger headache. The center pipe is designed to try to ensure there is always wort on the element. Just something to consider. I agree it isn't the easiest design to work with, but I mash very thin with the Robobrew and throttle the recirculation so it keeps a small layer of wort just above the grain bed with just a trickle going down the center pipe.
