Patent ID: 7987777

Claim:
A process for improving a tall grass biomass baler, the tall grass biomass baler comprising a baling chamber adapted to receive tall grass biomass material and a compression system adapted to compact the material into a parallelepiped bale in the chamber, wherein the baling chamber comprises a front wall consisting essentially of 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 W and H of the bale, and opposing sidewalls corresponding in dimensions to the L and the other of the W and H of the bale, the improvement comprising configuring the baler such that each chamber wall selected from among the upper wall, the lower wall, and each of the sidewalls can withstand a distributed force perpendicular to the selected wall of at least (0.22×Pp psi×Aw) pounds, wherein 0.22 is a Poisson's ratio value, 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.
