As weIl as the production of bio ethanol, the
production of bio diesel has also been growing
continuously. This is partly due to rising crude oil
prices in the world markets, the development of
technologies allowing the generation of new
fuels from renewable raw material sources, and
the considerable efforts taken by national and
international politicians with regard to climate
The traditional source of material for bio diesel
production has been fresh vegetable oil extracted
from plant seeds. However, used edible fats, oils
and animal fats are also used. In Northern Europe
mainly rapeseed oil is processed. In the USA, it is
mainly soya bean oil, while in tropical countries
palm oil is the main source of the raw material.
The HILLER - DecaOil centrifuge is a solid bowl
decanter centrifuge especially designed for highly
efficient, continuous sedimentation of solids and
separation of one or two (non-mixable) liquid
phases. The feed enters the rotating bowl through
a stationary feed tube and is thrown radially
outwards into the bowl through feed ports in the
conveyor hub. By means of centrifugal force, the
solids and liquid(s) are separated
from each other.
