2357. Osmundsen, R., and Osmundsen, J. M. Feb. 22, 1911, [Convention date]. Fatty oils, extracting by rendering. Apparatus for rendering comminuted fish &c. comprises a steam-digester 1, through which the flesh is conveyed by a series of perforated conveyerbands 15, the oil being led away by shoots 16, preferably into a jacket 8, in which a further boiling is effected by the steam from the digester. The digester 1 may be rectangular and the jacket 8 circular in cross - section. The jacket may be omitted, or replaced by boxes conveying the discharges from the shoots 16 or the bearing of the rollers 14. The flesh is fed from a hopper 2 by a two-part piston 17, 18 and is forced by steam from the pipe 4 through the opening 21 on to spreading-rollers 22. A piston 26 counteracts the pressure upon the piston 18. The treated flesh is discharged by a screw &c. 3, and is then pressed, dried, &c. It may be dried bv superheated steam, which passes from the drier through a pressure-regulating valve, to obtain saturated steam, to the digester 1 and then back to the superheater, it may be through a condenser and the boiler.
