Making the Fastest Smelter I Possibly Can

Minecraft Furnaces are very slow, so I am making the fastest Minecraft redstone furnace system that I possibly can. This is the ultimate super smelter for Minecraft 1.17, created in the latest Minecraft snapshot for the caves and cliffs update, we make use of the dripstone lava mechanic to have infinite fuel for Minecraft furnaces. This automatic super smelter is an industrial Minecraft furnace array with 300 furnaces working together to smelt items as fast as possible in Minecraft.

    What a beautifully complex way of wasting hundreds of lava buckets. Unless you plan to smelt items by waves of 30000 of course.

    couldn't you make this faster if you had blast furnace for ores, smokers for food, and normal furnaces for everything else?

    Next up Mombo adds a cache system that if the system has the items cached it sends the cached items instantly to the user and then smelts and redeposits the cached items.

    You got the idea going on for speed, but I am pretty sure that the full-auto smelter works better if you just use coal. This is because you can fuel the thing with coal blocks as those have a longer fueling time per slot.

    You could use droppers activated at the end of each furnace to pop items into some waterflow, this will avoid destructing the hopper minecarts, and I guess the water flow will works just as well ^.^ And btw, the lava bucket supply is wonderful XD

    Well the item pickup system is going to have issues with running out of hopper minecarts...the other issue would be getting the buckets back up to the top to get the lava back into the buckets to be back in the fueling system, but otherwise i see no issues with it.

    When he said he was using an automated fuel source I was thinking bamboo, not lava. I know that dripstone+cauldron+dispenser with bucket is now infinite lava, but I would not have thought to use it as a fuel source, especially given the hassle of moving the buckets around.
