sunflower oil plant for sunflower oil processing to make cheap
sunflower seeds into more valuable and healthy sunflower oils. The
sunflower is a distinctive, flowering plant (Helianthus annuus L.), the
seeds of which contain a valuable edible oil that contains more Vitamin E
than any other vegetable oil. Most sunflower oil is used in food
products. The seeds of confection varieties of sunflowers are also sold
for human consumption and birdseed.
Sunflower seeds oil press and Pre-pressing Plant Introduction:
Oilseeds pretreatment process is an important step to improve the
appearance of oil.In order to quickly and efficiently get high quality
edible sunflower oil, It usually consists of the following series of
processes: drying of sunflower seed, color sorting, crushing, softening,
peeled, extrusion, flaking, steamed and fried ,pressing etc.oil
pretreatment and pre-pressing section has different processes and
configuration, because of varieties of oilseeds, requirements of final
product quality, the structure of product variety,different capacity,
etc.

The functions of each pretreatment machine used in sunflower oil processing plant:
1. Cleaning machine: To remove the impurities in sunflower seeds, in
order to ensure good work condition and production stability.
2. Husking and kernel & shell separating machine: To decrease the
residual oil in shell. Because the sunflower seeds' shell don't contain
oil at all.
3. Flaking machine: Using mechanical power, particulate sunflower seeds
will be rolled into flakiness, which is easy to roast in cooking machine
in next step.
4. Cooking machine: To adjust the temperature and moisture of sunflower seeds, easy to extracting sunflower oil.
The introduction of sunflower oil press machine:
Screw sunflower oil press machine with auxiliary frying pan is mostly
choice in sunflower oil processing plant. These kind of oil press
machine can finish one time squeeze, has low energy consumption and
small footprint characteristics, and is the ideal oil press machine for
large scale sunflower oil processing plant.
Extracting section of the sunflower oil plant
Extracting section is to extract the oil by suitable organic solvent, this method can get the highest oil yielding rate.

1>Extracting:To extract the oil in the cake by solvent, the general
solvent is 6# extraction solvent oil or commercial
hexane.2>Desolventising: To remove and recover the solvent in the
meal; Dry and cool down the meal at the same time.3>Evaporating and
stripping: Heating the the miscella by indirect steam, so that can
vaporize the solvent and concentrate the miscella.4>Solvent
recycling: This process is to recover the solvent, decrease solvent
comsuption, keep safety prodution and improve product quality.
sunflower oil refining machine
provides professional oil refining process of degumming, dehydration,
dea-cidification, decolorization, bleaching, deodorization, and
dewaxing.The purpose of oil refinery: Remove crude oil contained in the
solid impurities, free fatty a-cids, lecithin, gelatin, wax, pigment and
peculiar smell, etc. to make oil reach edible or industrial standard.
sunflower oil refining machine flow chart:
Crude sunflower oil→degumming→washing and drying→decolorization→deodorization→dewaxing→edible oil
Quality Requirements of Crude Oil:
1,Moisture and volatile matter of crude oil: ≤ 0.25%;
2,Impurity content of Crude oil: ≤ 0.2%;
3,A-cid value of crude oil (mgKOH/g): ≤ 7.
Technological Characteristics of Oil Refinery Plant:
1.continuous alkali refining shorten the contact time between oil and
alkali liquor, reduce oil saponification, low consumption, improve
efficiency;
2.Decoloring adopt the technology of combined premix and steam mixing
bleaching, improve discolored efficiency, save consumption of bleaching
clay, easy operator and convenient; Negative state avoid oxygen in the
air to contact with hot oil, ensure quality of oil, inhibiting a-cid
value to raise again, and lowering peroxide value;
3.Physical refining section adopts new type continuous dea-cidification
and deodorization craft, which is applicable for vegetable oil of high
a-cid value and low resin content, the actual production proves its most
obvious advantages as following: strong dea-cidification ability
,excellent hot bleaching effect, high refining rate ,good oil quality
etc.
4.The process has multiple heat exchange, which makes full utilization
of heat energy, effectively reduces steam consumption,and also has the
advantages of production process ,flexible operation, high automatic
degree, environment sanitation and so on.
Degumming section
After pressing process, there will exists some impurities in the crude
sunflower seed oil, which need to be removed. In this degumming section,
we use the aqueous method to dissolve the impurities like gum, protein
and phospholipids by washing the crude sunflower seed oil for 2-3 times
with hot water.
Neutralizing section
The neutralizing section is for neutralizing the free fatty a-cids, which
is called dea-cidification section as well. The free fatty a-cid is
harmful to human health, so it should be removed. The caustic soda is
used in this section to saponify the free fatty a-cid to be soap stock,
thus the small soap granule will sink and be pumped out.
Decolorizing section
Due to the existing of carotene, xanthophyll etc, the color of most
crude sunflower seed oil is dark. The bleaching clay has strong
absorbing ability to be used for absorb the pigment in the crude
sunflower seed oil, an after filtering the clay, the pigments will be
removed and the color of sunflower seed oil will be brighter than
before.
Deodorizing section
The pure sunflower seed oil has no odor, but the crude sunflower seed
oil has some smell odor. The deodorizing section aims to remove the
special odor of the crude sunflower seed oil which cause by the volatile
matters, like the oxide for aldehydes, ketones, hydrocarbons, so we use
the steam to absorb the odor in this section and make the volatile
matters remove out with the steam.
Dewaxing section
After deodorizing section, the sunflower seed oil still has a little wax
inside, so this dewaxing section is equipped for removing the wax
inside of the crude sunflower seed oil. According to the different
melting points of wax and oil, we use cooling method to separate the
crystal wax, and then filter the sunflower seed oil to realize the
purpose of separating the wax from the oil.
