Tilted floor
Pellet store
The slanted floor must withstand the weight of the
pellets (bulk weight 650 kg/m³). Assuming the usual
commercially available formwork panels with a width of
100 cm, members of the support frame should have a
separation of 50 or 100 cm. For these separations, the
following tables show the required beam thicknesses
depending on the room width.
Tilted floors may not touch the wall
The tilted floor may not touch the wall, otherwise
noise emissions will be transferred. For this
reason, a small gap is to be left between the tilted floor
and wall, and sealed with silicon.

Mounting the suction probes on a wooden board
If the suction probes sit directly on a cold concrete
floor, water from the circulating air can condense on
them. The condensation can cause pellets and, in
particular, pellet dust to form clumps that can clog the
pneumatic conveyor. To avoid this, always mount the
suction probes on a wooden board (25 or 27 mm thick)
and fasten it to the floor.

Pad wall opening for conveyor screw trough
Sound from the screw can be transmitted through the
pellet store walls into the house. To avoid that, pad the
wall opening for the troughs with soft material (mineral
wool).
Under no circumstances should the conveyor screw
trough be cemented into a concrete wall without
acoustic insulation.
Small store rooms with reserve
For small pellet stores, the tilted floor can be truncated.
A reserve of pellets will remain on the resulting flat
surfaces; when the main store is empty, the reserve
pellets can be manually swept into the main store.
Fig. 12-12: Reserve
The disadvantage of this method is that the reserve
space must be cleared at least every three years to
prevent an accumulation of dust and broken or moist
pellets.
