Title: Method and means for stuffing natural casings with sausage emulsion.
Inventor: MICHAEL J HARDY
IPC: A22C11/06
Filed: 2003-03-25
Abstract: A method of stuffing natural casings with emulsion involves slidably mounting a collar element (28) on the stuffing tube (14) of the machine adjacent an end of the stuffing tube opposite to the discharge end (14A) thereof.
