On the processing installations we can see the machines placed in the basement with pulleys and belts of different sizes, their use varied depending on the needs of power required by each machine upstairs. The traction was only one, either from an electric engine or a water wheel. An innovating aspect at that time was the fact that the pulleys were placed underground to make it safer for employees to work.

In the basement of the bunker silo we can find a worm gear that transported coffee beans from the silo to the processing shed. This was a great advance for the time, considering that the use of this system in agriculture started in Brazil, on a large scale, just over 20 years ago. It is also possible to observe that the construction of this building happened before the processing shed because here we can see that some of the wood was cut using an axe, therefore, prior to the construction of the sawmill.
