Auto Heavy Sieve
It can be powered using any Forge Energy compatible mod.
If a mod adding steel is loaded, the recipe will require steel instead of iron.
To speed up an Auto Heavy Sieve, one can feed the tiny person inside to make them work faster. Any food will work; the tastier the food, the more it motivates your sifter to work faster.
Additionally, the mesh used inside the sieve can be enchanted with either Unbreaking, Fortune or Efficiency.
