Multi Smelter

The Multi Smelter is a MV tier multiblock for mass smelting vanilla furnace recipes. All smelting recipes have a base duration of 6.4 seconds and consume 4 EU/t (LV). The Multi smelter is a direct upgrade from the Steam Hearth because it can overclock down to 0.05s (1 tick) and has a built-in 4 parallels that doubles with every heating coil tier, including cupronickel. The maximum number of parallels is 65,536 with eternal heating coils. The Multi Smelter even has the unique ability to run different recipes in the same iteration if there are parallels available. The Multi Smelter is technically superseded by the Forge of the Gods in UIV, but it still scales very well on its own.

The Multi Smelter is built like a small Electric Blast Furnace. Buses/hatches are limited to the casings on the bottom layer of the structure, except the muffler hatch which replaces the top center casing. Multi-amp and laser energy hatches are not supported and having multiple regular energy hatches does NOT overclock the machine. Use the Multiblock Structure Hologram Projector to visualize/build the structure with subchannel "coil" to specify the tier of the heating coils.

Structure

• Controller: Front bottom center
• 8-12 Heat Proof Machine Casing
• 8 Heating Coil (Tiered)
• 1 Energy Hatch: Any bottom casing
• 1 Maintenance Hatch: Any bottom casing
• 1 Muffler Hatch: Top center casing
• 1+ Input Bus: Any bottom casing
• 1+ Output Bus: Any bottom casing
• Mandatory Air: Interior of the structure

Wallsharing

Multi Smelters may wallshare each of their sides to save on heating coils, casings, and buses/hatches. No recipe uses more than 1A of power so it is possible to share one energy hatch between two machines.

All smelting recipes have a base duration of 6.4 seconds and consume 4 EU/t (LV). The Multi Smelter can overclock that down to 0.05s (1 tick) and has a built-in 4 parallels that doubles with every heating coil tier, as seen in the following table. The maximum number of parallels is 65,536 with eternal coils and the maximum EU/t is just slightly less than 1A of the current voltage. Once the minimum duration reaches 1 tick (or batch mode is enabled), the machine starts to double the number of parallels with each overclock instead.

The Multi Smelter also has the unique ability to run different recipes in the same iteration if there are parallels available. For example, it can smelt 512 iron dust and 512 copper dust at the same time. This is only possible because all smelting recipes have the same base duration and EU/t.

Batch mode is enabled by default and highly recommended because it saves TPS and reduces lag. However, batch mode does NOT improve the throughput of the machine like parallels do. Recall the difference:

• Batch Size - More recipes per iteration, same EU/t, longer duration.
• Parallels - More recipes per iteration, higher EU/t, same duration.

• The Integrated Ore Factory is the only other multiblock that can process different recipes simultaneously.
