ABSTRACT:
The invention concerns a feeding device installed in a loading bin of a sausage filling machine, consisting of a feed screw 2 which is affixed to a mounting ring 1 that is attached to a roller bearing including a gear rim 10. The mounting ring 1 is provided with at least two upper gaskets and two lower gaskets whose function is to prevent any eventual migration of lubricant from the mechanism housing 26 from contaminating the meat product area 7, while at the same time preventing any contaminating effect of the sausage meat in the opposite direction. The spaces that develop between each pair of gaskets create cleansing areas 13 which assure that such contamination cannot occur. The cleansing areas 13 may also contain a lubricant for the above mentioned gaskets.
