Fermenter (RotaryCraft)

The Fermenter is a machine from RotaryCraft. It is used to produce Sludge and Yeast, which are used to create Ethanol Crystals. The power input can be from the back side, and must be a minimum of 1024W at 32 rad/s. Its operational speed rises as the input speed does. It is temperature-sensitive, meaning that very high or low temperatures will slow it down and possibly kill the yeast, while optimal temperatures will speed the process along successfully. It requires an input of water as well as the items needed to ferment the materials.

Duration
The duration of a fermenter (in ticks) as of Minecraft 1.7.10, Rotarycraft v19a, is: 480 - 35*log2(speed + 1)

Tips and Tricks
With the given duration formula, the Fermenter can operate once per tick (max speed) with an input speed of 16 krads/second. This can be provided by a steam engine with a 32x gear ratio set for speed.

The Fermenter also has an "ideal" temperature it works at. Outside of this temperature, a small multiplier is applied that slows down the operation, which grows exponentially. Generally speaking, the fermenter works optimally during the day, but shuts down at night, or requires heating and cooling to get it within optimal temperature during that time.
