9018. Meerdervoort, H. J. A. P. van. April 19. Manures. - Sterilized oils and guano are obtained by digesting fish in closed vessels at a pressure of about three and a half atmospheres. Fig.5 shows a plan of the apparatus for making the guano. The residue left after the extraction of oil is fed through the opening A into a press cylinder B which is provided with a sieve-like receptacle C and a hydraulic or like plunger D. The expressed liquids are drawn off through the tap E, and the partly-dried solid matter is forced into the cylinder G, which contains a perforated cylinder H and a screw conveyer J carrying arms or vanes K having hammer-like ends L for comminuting the material. Hot air at a high pressure is forced in from the heating-chambers M and drives the fine material to the chamber N, whence the air escapes through the chimney O.
