Expeller??Oil pressing machinery??

An expeller press is a screw-type machine that mainly presses oil seeds through a caged barrel-like cavity. Other materials used with an expeller press include but are not limited to meat by-products, synthetic rubber and animal feeds. 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 left over 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. Some raw materials, however, do not release oil by simple expelling, the most notable being rice bran. In order to remove oil from commodities that do not respond to expelling or to extract the final traces of oil after expelling, it is necessary to use solvent extraction.

There are often fake commodities and leaching processing oil on the market, harmful to health.
