Systems and methods for improved rendering of animal products may utilize amulti-stepprocess including at least a heating step through use of a steam-jacketed tubesystem and apressing step to squeeze out the oils. Grinding and pre-breaking may first beused to break thefat/whole animal into pieces. The ground material may then be transported andheated in one ormore steam-jacketed tubes to create a slurry. A press may then be employed topress out the oiland water from the slurry. Residual solids may be removed from the oil andwater through adecanting step. Water and extremely fine materials may then be removed fromthe oil through acentrifuge step, and the oil may be transferred to one or more storage tanks.Following thepressing step, the protein that remains may be subjected to high pressure tosqueeze out anyresidual fat and then may be transferred to a hammer mill to prepare into apowdered protein orother desired protein material that may be stored for later use.
