Hydraulic presses
These are used in the large
installations. They are of two main
types-open or Anglo-American
presses and the closed or cage type
presses. In this the space between the
plates above ram and the head is
divided by plates between which
copra is put wrapped in press clothes.
The common method is to extract
oil from copra or the dry coconuts.
Conventionally coconut oil is
produced by expelling dry copra,
followed by refining during which
oil is exposed to high temperature.
The copra based refined coconut oil
or the solvent extracted and refined
coconut oil will have a bland taste
due to the refining processes.
