The Bioreactor is a Factory station that runs autonomously and processes Wheat into Zombie Power. Despite the icon suggesting a zombie-based input, Wheat is the actual base resource. It has one Conveyor Belt input and one Conveyor Belt output.

More context

Connect Conveyor Belts at both ends like any other Factory station. Feed it Wheat via a Conveyor Belt from the Garden Storage — set up a Lifting Crane in the garden to send Wheat down — or load a Conveyor Chest and let the chest feed the Bioreactor. Place a Conveyor Chest at the output to buffer Zombie Power for the Bishop quest or future Assembly Bench II crafting.
