Two stage meat strainer

In combination, a first press for separating meat from bones including a cylindrical pressure chamber for containing a combination of meat and bones to be separated, a lining sleeve within the pressure chamber having openings therein, a collector channel surrounding said lining sleeve, and a pressure means within said pressure chamber and operatively extending into said lining sleeve for exerting pressure on the meat and bones within said pressure chamber to partially separate the meat and bone combination by forcing meat and some bone outwardly through said openings in said lining sleeve into the surrounding collector channel, and a second press for further separating meat from bones, said second press comprising:

• a cylindrical wall defining a cylindrical pressure chamber for containing meat and bones to be further separated and being in communication with said collector channel of the first press,
• a sealing wall attached at one end of the pressure chamber of the second press opposite the auger for closing off the end of the pressure chamber of the second press opposite said auger when meat and bones are to be separated in said pressure chamber,
• a cylindrical lining sleeve within the pressure chamber of the second press having openings extending therethrough, said openings in said sleeve of said second press being smaller in diameter than said openings in said sleeve of said first press,
• a collector channel surrounding said lining sleeve of the second press;
• and
• an auger rotatably mounted within the pressure chamber of the second press for advancing the partially separated combination of meat and bones from the collector channel of the first press into the pressure chamber of the second press and for further separating the combination of meat and bones by forcing meat outwardly through said openings of said lining sleeve of the second press into the surrounding collector channel of the second press.
