Product is fed into the feed chamber where the auger or screw forces it into the dewatering chamber. This is fitted with a s/s twin screen, which is conically shaped through which only liquid or thin slurry can pass.

Expeller pressing (also called oil pressing) is a mechanical method for extracting oil from raw materials. The raw materials are squeezed under high pressure in a single step. When used for the extraction of food oils, typical raw materials are nuts, seeds and algae, which are supplied to the press in a continuous feed.

Expeller presses can recover 75% of the oil from algae] As the raw material is pressed, friction causes it to heat up; in the case of harder nuts (which require higher pressures) the material can exceed temperatures of 120 Degrees F.

An expeller press is a screw-type machine that 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 drives to move and compress the seed material.

The oil seeps through small openings that do not allow seed fiber solids to pass through. Afterward, the pressed seeds are formed into a hardened cake, which is removed from the machine.

Pressure involved in expeller pressing creates heat in the range of 140-210 F (60-99 C). Some companies claim that they use a cooling apparatus to reduce this temperature to protect certain properties of the oils being extracted.

Expeller processing cannot remove every last trace of liquid (usually oil) from the raw material. A significant amount remains trapped inside of the cake leftover after pressing. In most small scale rural situations this is of little or no importance as the cake that remains after the oil has been removed finds uses in local dishes, in the manufacture of secondary products or for animal feed.
