Juice and Processing Plant in Farmstead World — building in the game, and what it is on a real farm.
A juice plant presses fruit for its juice and then pasteurises it, heating the juice just enough to stop it fermenting on the shelf.
Pressing, filtering and filling run as one line, so the fruit goes from bin to bottle while it is still fresh.

A juice plant presses fruit and pasteurises the juice so it can be bottled and stored; without that heat step, fresh juice ferments within days. (en.wikipedia.org)
