Feeding Through

A primitive device that will allow you to provide sustenance for your humans.

Connect it to a food processor with a pipe through the input (indicated by the green arrow) to keep it full at all times without your intervention. You can also fill it manually, although this means the humans could see you.

The green stuff, as you can imagine, is not that palatable. You an asume humans are not a fan, but will eat it for sustenance. More gourmet options will open up as you further your research.
