Abstract
An efficient method and apparatus for making a compressed structural fiberboard from agricultural fibrous matter. The method and apparatus provides a conveyor having variable drives for carrying the agricultural fibrous matter; a hopper having variable drives for conditioning and delivering the agricultural fibrous matter to an extruder; the extruder having a cyclic ram with linear actuators and a floating plate to drive the cyclic ram between an extended position, wherein the agricultural fibrous matter is compacted into the compressed structural fiberboard, and a retracted position, wherein the agricultural fibrous matter is delivered to the extruder; synthetic oil heaters for heating the compressed structural fiberboard; a heat sink track cooler for cooling the compressed structural fiberboard; and a water jet cutting system for cutting the compressed structural fiberboard into individual boards.
