The Horizontal Pressure Leaf Filters
shown recently shipped from our factory to
one of the Edible Oil Refinery in Pakistan.
With filtration area more then 50 m2…, they
are among the largest filters made in our
plant for Dewaxing of Sunflower Oil.
is a separation process which allows the
removal of higher melting point crystallized
parts (waxes or some triglycerides) that are
responsible for the turbidity of some edible
oils in the winter or after refrigeration.
In the case of sunflower oil, this process
can also be called ‘Dewaxing.’
method can be used for Dewaxing sunflower
oil. The conventional method, which consists
of a gradual crystallization with special
Kiselgur (Hyflo-super-cell) maturation and
separation by HPLF.[ HORIZONTAL PRESSURE
LEAF FILTER ]
The wax content
of the oil depends on the oil content of the
sunflower seed and the process of
technology. Generally for sunflower seed
with an oil content of at least 40% and the
wax content is 0.65%-2.33%.
operation, it is necessary to remove the
gums before Dewaxing.
The cooling and
crystallization time, in the presence of
Kiselgur, mixed with a small part of oil, is
pumped from a special mixer in the
crystallizer. In this crystallizer, the oil
is mixed very slowly and cooled oil is
introduced into the maturator to form the
filterable β crystals. The maturator
(without cooling coils) also has a low-speed
agitator. The recommended maturation time is
maturation, the oil is pumped through an oil
heater to the HPLF. The oil is heated from
7ºc to 12º-15ºc.Before filtration; a
precoating layer is introduced into filter.
