METHOD OF TREE SAP EXTRACTION BY SQUEEZING, TRUNK SHREDDER, AND TREE SAP EXTRACTION SYSTEM

摘要

Provided is a trunk shredder which comprises a feeder assembly (13) for feeding a tree trunk (T) in the longitudinal direction from the front end face thereof, and a cutter assembly (15) for producing small cut pieces of a tree trunk (T) transferred by the feeder assembly (13). In the cutter assembly (15), a cutter blade placed in a direction crossing the longitudinal direction of the tree trunk is moved relative to the front end face of the trunk (T), and cuts the front face into small cut pieces. Then a sap-extracting machine squeezes the small cut pieces to obtain tree sap efficiently.
