g a seventh pneumatic action consisting of blasting chilled air through the pneumatic cleaning element i e air comb for the purpose of causing the woody core to more rapidly and easily separate from the fibrous materials h an eighth pneumatic action inversely consisting of blasting heated air through the pneumatic cleaning element i e air comb for the purpose of rapidly reducing the moisture content of the fibrous materials i a ninth decortication action derived from engineering the lower scutching roll to travel at greater peripheral speed than the upper breaking roll to increase the cleaning efficiency of said lower scutching roll j a tenth friction reducing action provided by the slick hydrophobic coating finishing or material applied to the feed table feed table edge and all air comb blade tips that allows the fibrous materials to slip and flow through and over the previously listed elements k an eleventh lateral guiding action throughout the process beginning in the feed element with lateral baffles and continuing through the breaking and scutching rolls with concave blade tips lateral control is also enhanced by a decortication element width that exceeds the feed element width by 0 5 or more inches on either side 5 a plant stalk decortication method according to claim 5 that utilizes an air blasting feature located in the peripheral tips of the breaking and scutching blades and otherwise referred to as an air comb to minimize the duration and degree of contact between said blades and the fibrous materials resulting in less severe bending and depth of intermeshing between the blades of the breaking.
