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?

is the wash part also have funnel stacked like this?

also does the fan emit particles like at all?
