**3.2 Clog sensor stem improvements**

The M710 screw clogging sensor is simply a rod with tabs that when rotated by the build-up of biomass, triggers a physical sensor that stops the thread. During the observations, it was evidenced that the rod was very close to the biomass level of the screw itself, causing the material to pass over the rod, and not under, as it should be. In this way, the rod, in addition to not being activated as it should, served as a barrier for the free fall of biomass, being a major clogging point. By increasing the height of the stem by approximately 21 cm, it was possible to observe that the transported biomass returned to normal flow, eliminating an accumulation point.
