There is Simply Nothing Else Like It. Engineered specifically for depackaging, the innovative Tiger HS 640 combines the action of a shredder, screen and extrusion auger in a single machine. After wet or dry materials are loaded into the hopper, the unique action of the Tiger mechanism separates the organic fractions from the inorganic packaging, producing both solid and liquid extracts in the discharge. Perfect for aerobic digestion operations, the output (up to 30 tons/hour) from the Tiger HS 640 quickly generates high volumes of biogas energy. No pretreatment, no material prep, just turn it on, load it up, and generate more revenue from your source material.
