Descripción del producto
Palm oil is the world's second largest edible vegetable oil. Palm
plantation of low cost, low palm oil prices, thus has a strong
competitiveness in the world oil market. Population in our country,
the demand for vegetable oil has been improved, China's oil demand
will keep growing at 5%, to ***0, total demand of 2 8 million
t.
The purpose of the oil refining is to remove impurities, to achieve
the finished product oil standard. Process main process is: crude
oil, degumming, neutralization, decoloration, deodorization, points
to mention. Add water hydration degumming, alkaline acid
neutralization or steam distillation, and adsorbent activated clay
or active carbon decoloring, high temperature vacuum deodorization
and removal of smoke at low boiling point volatile matter.
- crude oil filter
Buy back crude oil should be filtered, leaching, suspended
particles impurities and other impurities to the following
production.
- the degumming
Colloid phospholipids mixture, sugar, protein, trace metals and
other impurities. Degumming is the impurity removal process, the
quality of the raw material oil to a great extent, determines the
final quality of the products, raw materials of colloid is an
important factor affecting the quality of oil and grease. These
impurities that oil is not in contact with catalyst, reducing the
cracking rate, no degumming directly and difficult to operation and
increase due to emulsification oil loss, colloid is why fat double
bubble, harmful to the stability of the product and colour.
3. neutralize
Neutralize acid has a great influence on the product quality and
the price is the procedure, if the neutralization process has a
problem, can bring difficulties to after decolorizing of each
working procedure, and lower the product quality and yield. And
usually has two methods of the physical and chemical methods, the
principle of physical refining method namely gas stripping
distillation acid should be as a process of choice for oil
refining, chemical neutralization method with sodium hydroxide and
hair oil, free fatty acid in the acid soap stock and waste water is
produced. But physical refining method or chemical refining method
choice, mainly depends on the quality of the crude oil.
4, decoloring
Bleaching is one of very important working procedure in the oil
refining process, it besides pigment in removing oil, can reduce
phospholipid content, peroxide value, soap content and the content
of metal ions, thus improving product color, flavor and improve the
oxidation stability, for further refining of oils and fats
hydrogenation, deodorization provides a good condition.Oil
decoloring by far the most commonly used method is activated clay
adsorption decolorization method, namely using clay which has
strong selective adsorption material, under certain conditions in
removing the pigment in soluble in oil or colloidal particle
dispersed pigments and other impurities in the oil.
5 deodorization
In oil deodorization process, in addition to complete the purpose
of deodorization, is now more emphasis on realistic now under the
low temperature, short time of unit operations, inhibit the
generation of trans fatty acids, reduce the loss of tocopherol,
lower polymerization, reduce the decomposition of vitamins (A, D,
E).Temperature is **0 ~ **0, vacuum residual pressure is 6 ~ 8 mm .
In order to prevent oxidation, before into the tower through
degassing, direct steam is in order to improve the effect of
deodorization. Heat oil recovery can be achieved by cold and hot
oil heat exchange to achieve.
6. fractionation
Fractionation is the special handling for palm oil is put aside,
namely the palm oil cooled to
℃ or so and keep a certain time, the
composition of high melting point and crystallization
precipitation, the secondary filter can be "points" into three
different melting point of the product, these three products for
palm stearin melting point higher than *0
℃, brown put soft butter melting
temperature *0
℃ or so
and liquid palm oil melting point below *0
℃.These three products yield about
*0%, *0% and *0% respectively, including liquid brown oil quality
can reach the standard of cooking oil
henan huatai food & oil machinery engineering Co., ltd is
a famous food oil processing enterprise in China.we are especilly
professer in palm oil processing line.
