Tutorial:Automatic smelting

For a tutorial on smelting items manually, see Tutorial:Smelting.

The purpose of this tutorial is to teach how to smelt items automatically, without having to put them in and get them out manually. You will need hoppers, furnaces, and at least three chests. Additionally, furnaces can be replaced with smokers for faster cooking of food or blast furnace for faster smelting of ore or nuggets.

Semi-automatic furnace

I

O
Semi-Automatic Smelter.
I is Input (smeltables)
F is fuel
O is output.

This semi-automatic design uses hoppers, and is not too difficult to build and is inexpensive.

You will need 3 chests, 3 hoppers, and 1 furnace. The raw ingredients for this would be 8 cobblestone, 15 iron ingots, and 12 logs of wood (48 planks).

Build instructions

See below for a step-by-step guide on how to make this semi-automatic furnace design. Sneak (hold down shift ( On PlayStation press the right Stick or R3, on Nintendo press the a button, and on Xbox press the b button.)) to attach blocks to each block that has an inventory, such as attaching a hopper to a chest. Otherwise you will open the block instead of placing the block. Connecting a second smelting module next to the first smelting module (making sure that the chests in both modules become double chests) will make the smelter twice as fast.

  • 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: Attach a hopper to the chest.
  • Step 3: Place the furnace on top of the hopper.
  • Step 4: Place one hopper on the top and 1 hopper on the side (left, right, front, or back) of the furnace. (The top one will insert the items into the furnace, which get smelted / cooked; The hopper on any side-face inputs fuels into the furnace)
  • Step 5: Place a chest on top of each hopper attached to the furnace.

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.

Multiplayer: On servers that have chest and furnace protections, you may have to unlock these before the hoppers are able to interact with them.

Automatic item sorting furnace

This fully-automatic 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:

Tiny fuel generator

Charcoal

Tiny Charcoal Generator 

View at: Tutorial:Automatic smelting/Tiny Charcoal Generator [edit]

This design lets a furnace producing charcoal feed its product back into the furnace to fuel itself. It needs to be started off with one piece of charcoal (or for that matter, any fuel) in the chest. If more than 5-6 stacks of wood are available, another chest for input can be placed atop the upper hopper. Note that this design uses a comparator, which requires access to nether quartz.

The chest will not start receiving charcoal until both the furnace and the hopper feeding it fuel (level 2) are full. However, the hopper can be "stuffed" with four non-fuel items in its last four slots, as long as you leave the first slot open for fuel. Then the chest will start getting charcoal after two stacks of charcoal are produced, which will require 2-1⁄4 stacks of wood.

See the following video for an example of how to make this:

Bamboo

Large smelters

These smelters are designed to be extendable and handle large amounts of items.

Mumbo Jumbo's design

This design can go up to 6 smelters and can produce, at most, 6 times faster.

ilmango's design

This design is more recent and more efficient due to the new blocks.

Mysticat's design

1man1game's design

JC Playz's design
