“DEWAXING OF SUNFLOWER OIL”
Winterization 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
The following 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
For good 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 5-6 hour.
From 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.
Abhishek filter's Candle Filter
consists of cylindrical shaped long filter elements made
out of Equi-Diameter pipes. Each candle is covered with
filter Socks in polypropylene, Polyester, Nylon or PVDF.
These candles are housed vertically in a pressure
vessel. Unique design helps in proper filtration and in
end of the Process you get uniform Cake Deposition ,
this hapens in Strictly under ideal Pressure. Wet or dry
discharge is possible by means of blow back. For
continuous operation Dual filters are Provided.
Rotary Vacuum Drum Filters
The Vacuum Drum Filter has a broad field of application,
amongst others in ore refining, hydrometallurgy,
metallurgic, chemical and pharmaceutical industry, food
processing and waste water treatment.
A rotary drum vacuum filter (RDVF) is a continuous
filter wherein the solid constituent in a pulp or slurry
is separated by a porous filter cloth or other media
rotated through the pulp or slurry, with vacuum applied
to the inner surface to cause the solids to accumulate
on the surface as a cake or layer through which the
liquid is drawn.
How it works :
The process cycle of the RDVF is continuous. Each
revolution consists of cake formation, cake washing (if
required), drying and cake discharge.
As the drum rotates - partially submerged in the slurry
- vacuum draws the liquid through the filter medium
(cloth) on the drum surface which retains the solids.
The vacuum pulls air (or gas) through the cake and
continues to remove liquid as the drum rotates. If
required, the cake can be washed prior to final
Product Range and Application :
The rotary vacuum filter can discharge its filtered cake
by means of any one of several discharge arrangements.
Normally a discharge device will be selected based on
the process material characteristics and how readily it
is released from the filtering media.
The Precoat discharge is used when direct
filtration against a cloth medium is not possible
because the cake cannot be removed from the cloth or
when blinding is indicated. It is typically used :
The Scraper discharge is used:
For fast filtering materials.
The Roll discharge filter is usually fitted with
a very tight filter medium to retain very small
particles and is used :
For discharging very thin, sticky (tacky) cakes.
Discharge Methods :
Single & Multi Microbag Polishing Filters
Abhishekfilters Single or Multi micro bag
polishing filters are basically used for
final filtration. The baskets are housed in
Vessel with proper sitting type
arrangements. Filter micro bags used are PP,
PPS, Polyster Polyamide or special material
depending on Filtrate conditions.
Depending on Capacity Micro Bag Filter can
