I think the screws for oil presses are different and unique -- the pressure is supposed to increase to very high levels by the end of the path, much higher than meat needs. > > Also, how could it be continuous?

Would a grinder still crush out > the oil if it came out the end like that? I believe their design is continuous, much like my ram press. The screw cap at the end allows you to adjust the pressure at the exit so that just the right amount of cake leaks out to allow continuous operation, but it comes out almost dry so you're not leaving any oil in it.
