Groundnut sunflower seed and vegetable planting machines for getting edible oil

Unlike almost other vegetable oils, corn oil is obtained from the seed that contained 3%-5% oil.

the maize germ accounted for about 6% to 7% of the corn granule.

According to the different maize varieties andmaturities ,oil percentage is differernt too, usually it can reach  38%~50%

Method of germ extraction mainly half wet, wet and dry.

Hydrometallurgy of embryo is the corn immersion, so as to achieve the purpose of embryo and starch separation, embryo extracting rate of 85% a 95% of the act,

germ moisture content as high as 60%, oil content of up to 44% 50%.

dry germ extraction without water regulating on Maize by mechanical method, but the corn and wheat germ separation.

Half wet extracting embryo of maize is moistening to a moisture content of 16% - 20%, and then by peeling, crushing and extracting embryo,

the embryo extraction efficiency can reach 85%.

Corn Oil Making Machine :

1.Deacidification
   Sodium hydroxide antagonize free fatty acids,and subside phospholipids,to remove the insoluble impurities,then after the separation of soapstock,

neutral oil was washed in soft water,last drying in vacuum.
2.Decoloration
   Corn oil pigments in two categories: one is the natural pigment, such as the carotenoids lutein materials such as chlorophyll,

these are easy to bleach,and the other type of the products of organic matter, these pigments are not easy to be bleached.
3.Dewaxing
   Dewaxing can ensure the colour of corn oil to be clear bright at room temperature and frozen temperature. to reduce the oil in the wax content to 10 parts per million

to get crystal clear oil.
4.Deodorization 
   Using high temperature and high vacuum steam stripping method deodorization temperature commonly 180, vacuum degree 9.3 104 Pa can achieve ideal results
