ABSTRACT:
Chunks of animal matter with 60% moisture content are fed into a cooker (1) via an inlet (3). Steam at 150.degree. C. is fed into a double skin via an inlet (6) and condenses to leave as water via an outlet (7). The application of heat to the animal matter causes greasy steam to be given off therefrom which leaves the cooker via an outlet (10). The remaining animal solids leave the cooker via an outlet (4) where they have a moisture content of 10%. The greasy steam is condensed in a condenser (19) and greasy steam condensate is discarded via an overflow (36). In the present installation, the major portion of the heat released by condensing the greasy steam is recovered and recycled, thereby reducing the energy requirements of the installation as a whole. This is achieved as follows: a portion of the greasy steam condensate is recycled via a heat exchanger (22) to be sprayed back into the condenser as the condenser cooling fluid; clean water is taken from a flash bottle (26) to act as the cooling liquid in the heat exchanger. After heating it is recycled into the steam in the flash bottle. Flash bottle steam is brought up to heating steam temperature and pressure in a compressor set (24), whence it is fed to the cooker. Condensed heating steam from the cooker is recycled into the water of the flash bottle.
