2. The oil expeller is a screw type machine,
which presses oil seeds through a caged
barrel-like cavity.
Raw materials enter one side of the press and
waste products exit the other side. The
machine uses friction and continuous
pressure from the screw drivers to move and
compress the seed material.
The oil seeps through small openings that do
not allow seed fiber solids to pass through.
3. The principle behind this equipment is
friction between the cylinder cage and worm
shaft assembled inside the cylinder.
The seeds are feed through the hopper which
connects to cylinder and worm shaft
assembly, as soon as the seeds reach the
rotating assembly it gets feeded to crushed
and oil is extracted.
4. Used to extract oil from oil seeds.
