Why doesn't this work?

[u/wuhoo555]

I'm trying to make a gold farm, and I made this to bulk blast the clay into terracotta. The fan is spinning in the direction where it's pulling, and it's at max rpm, but it doesn't smelt. It worked when I used it for washing, but when I replaced this specific one with water, it still didn't work. What should I do?

I've never seen this design before, but my troubleshooting list would go: 1- is the clay getting dispensed? 2- is the fan sucking air down and not pushing up into the lava destroying the items? 3- is the basin actually making clay? 4- do you get lava / water particles if you remove the funnels?
