Patent ID: 8430025

Claim:
A tall grass biomass baler comprising: a baling chamber for receiving a tall grass biomass material, the baling chamber comprising a front wall consisting essentially of a reciprocating compression platen corresponding in dimensions to the width (W) and height (H) of a parallelepiped bale, opposing upper and lower walls corresponding in dimensions to the length (L) and either of the width (W) and height (H) of the bale, and opposing sidewalls corresponding in dimensions to the length (L) and the other of the width (W) and height (H) of the bale, and a compression system for compacting the tall grass biomass material into a parallelepiped bale in the baling chamber, 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 wall of at least Fw pounds, in which Fw is determined by the formula: Fw ≧(0.22 ×Pp psi ×Aw ) pounds where 0.22 is a Poisson's ratio value of compressed tall grass biomass material, Pp is the maximum pressure that the compression system can apply to the material, and Aw is an area expressed in square inches of the selected wall.
