Patent ID: 8850970

Claim:
A woody biomass baler comprising: a baling chamber adapted to receive woody biomass material, and a compression system adapted to compact the material into a parallelepiped bale in the baling chamber, wherein the baling chamber comprises a front wall that acts as a reciprocating compression platen corresponding in dimensions to the width W and height H of the bale, opposing upper and lower walls corresponding in dimensions to the length L and either of the width W and the height H of the bale, and opposing sidewalls corresponding in dimensions to the length L and the other of the width W and the height H of the bale, and wherein each chamber wall selected from among the upper wall, the lower wall, and each of the sidewalls is configured to withstand a distributed force perpendicular to the selected chamber wall of at least (0.11×Pp psi×Aw) pounds, wherein 0.11 is a Poisson's ratio value of compressed woody biomass material, Pp is the maximum pressure that the compression system can apply to woody biomass material in the chamber, and Aw is the area of the selected chamber wall expressed in square inches.
