Abstract
Apparatus for liquifying material in the form of an unloading device includes a platen which may have a one-piece or two-piece structure. The platen preferably includes a plurality of fins with the openings between the fins communicating with a plurality of flow passages in the platen and a plurality of channels also communicating with the flow passages and located interiorly in the platen behind the fins. The various flow passages and channels lead to a discharge flow passage. The discharge flow passage may be directly connected to a pump or one or more discharge flow passages may lead to a chamber of the platen which further heats the liquified material before it is pumped from the platen.
