how the system works

The turbine creates a negative pressure in the pellet loader via the suction hose. The pellet loader is hermetically sealed and a vacuum is created. Just like a vacuum cleaner. Only here it is not dust that is sucked in, but pellets. The resulting vacuum also acts in the conveyor hose. Since the probe is connected to the conveyor hose, it uses the negative pressure to suck the pellets from the pellet storage into the pellet loader. To prevent a vacuum from also forming in the storage container, the "exhaust air" from the turbine is fed back into the storage/pellet bunker via the return air hose. This equalizes the pressure there.

The sucked in pellets now travel through the conveyor hose and end up falling into the pellet loader. There is a weight on the flap of the loader. This is balanced so that when a certain amount of pellets is reached the flap opens. If there are enough pellets to open the flap, the pellets in the loader push the flap open and the turbine switches off. The pellets fall into the stove's storage tank or an intermediate storage tank. If the storage tank is not completely full, close the loader flap again and the turbine switches back on. Suck in, collect, open the flap. Pellets fall into the storage tank. If the storage tank is almost full, the loader flap opens, the pellets fall into the storage tank but block the flap. This is intentional. Because the switch on the loader flap has now switched off the turbine. This continues until the pellets release the flap and it closes again. Then the turbine starts up again and the loading process automatically begins again.
