Abstract
A method of adding oil and fat to porous feed is disclosed wherein porous feed together with oil and fat are continuously inserted into a partially evacuated chamber of an oil and fat adding apparatus while, simultaneously, porous feed that has remained therein for a specified time is continuously being removed from the chamber. The continuous nature of this method allows porous feed having high fat and oil content to be produced more rapidly than previously possible.
Claims20
A method for adding fat and oil to porous feed comprising:
- providing porous feed directly from an extruder to a drier;
- drying the porous feed by heated air in the drier;
- inserting the dried and heated porous feed together with the fat and oil into a chamber of a fat and oil adding apparatus, wherein the dried and heated porous feed is inserted directly therein from the drier such that the dried and heated porous feed substantially maintains the temperature it possesses upon exit from the drier, there being a partial vacuum in the chamber of the fat and oil addiing apparatus and the inserting of both the porous feed and the fat and oil being performed in a continuous manner such that additional porous feed and fat and oil are constantly being inserted into the chamber of the fat and oil adding apparatus;
- keeping the porous feed and the fat and oil in the fat and oil adding apparatus for a specified time;
- and
- removing the porous feed from the chamber of the fat and oil adding apparatus after the specified time has elapsed, the removal of the porous feed being performed in a continuous manner such that porous feed is constantly being removed from the chamber of the fat and oil adding apparatus while additional porous feed and additional fat and oil are being inserted therein.
