Sunflower seed screw oil press was designed so that homesteaders
can produce sunflower oil from their own seeds. The oil can be
pressed as is or heated to 170 degrees F., which doubles oil yield.
Both methods require the seed to be ground to fine powder. If you
are pressing the oil seed variety, a meat grinder or electric
blender will do an excellent job of grinding the seed. This type
oil press belongs to the screw oil press machine. The confectionary
type of seed will require the seed to be hulled and winnowed before
it is ground.
A food mill with the stones set at the coarse setting can be used
to accomplish this step. The ground kernels are placed in the
cylinder with the piston closing the bottom portion of the
cylinder. Because of the great pressures created by the hydraulic
jack, it is important that the frame be properly constructed and
firmly mounted to the work surface before the pressing operation
begins. This type oil press machine is good enough to produce
sunflower seed oil.
