You will need 3 chests, 3 hoppers, and 1 furnace. To make these, you will need 8 cobblestone, 15 iron ingots, and 12 logs of wood (48 wooden planks). Build instructions Follow the schematic from the ground up. Sneak (hold down ⇧ Shift) to attach blocks to each block that has an inventory: Step 1: place down a chest on the ground. (This will be the chest in which the smelted / cooked items will be put) Step 2: sneak (hold down ⇧ Shift) and attach a hopper to the chest (side or top is fine). Step 3: sneak and place the furnace on top of the hopper. Step 4: sneak and place one hopper on the top and 1 hopper on the left side (important) of the furnace. (The top one will insert the items into the furnace, which get smelted / cooked; The hopper on the left side inputs coal into the furnace) Step 5: sneak and place a chest on top of each hopper attached to the furnace. Note: by using a hopper to empty the furnace, you will forfeit any experience points from the smelting. Variations: you may choose to add switches to control the hoppers. Switching off the bottom hopper stops it from taking items out, allowing you to collect the experience from smelting them. Switching off the top hopper allows you to fill the top chest with various items, then eventually smelt them all in one go, reducing the fuel waste normally incurred by smelting partial stacks. The fuel hopper on the side never needs to be switched off. SMP: On servers that have chest and furnace protections, you may have to unlock these before the hoppers are able to interact with them. Making two furnaces increases the rate of production much faster. Have a chest on top for the item to be smelted, and at the back, put a fuel chest. Automatic Furnace for Sorting Systems This build allows for seamless integration into an existing item sorting system and runs automatically in the background as a predetermined item is collected before reaching its final storage location. Items collected by the item filter will be smelted by an internal furnace, collected by a set of hoppers, and transported back to the main hopper line with a dropper item elevator to be transported to a chest or storage system. This design will require the occasional addition of coal or fuel, when its corresponding chest runs low, to keep the furnace running. The following items can be smelted with this automatic furnace design: Cobblestone Sand Iron ore Gold ore Netherrack wet sponges Clay
Haha, glad you like it! I tried to stuff as much information as I could in there. If you think anything needs to be added, let me know! Anything to fix/switch up, totally happy to check it out. Glad its useful
