With the increasingly raising of people's living standard, the selection for edible oil is also increasingly paid attention to.Sunflower seeds seed oil
Excellent healthcare function is aroused great concern, and the consumption for sunflower seeds seed oil is also advanced by leaps and bounds.
Production sunflower seeds seed oil is the method by squeezing sunflower seeds seed at present, main to include two kinds：One kind is band shell list
Secondary squeezing, benefit is simple and convenient, without carrying out excessive pretreatment, has the disadvantage that oil yield is low, and this is because the presence of shell is big
The big oil content that increased in press residue, causes oil yield to reduce, and the oil content in residue is up to 8%-10%；It is another
It is shelling single squeezing, advantage is that oil yield squeezes higher relative to band shell, has the disadvantage the sunflower seeds seed benevolence of shelling due to oil-containing
Unusual light, frictional force very little, into pressafiner after, enter to squeeze, fuel-displaced, all relatively difficult, the low production efficiency that goes out cake,
Although high with respect to oil yield, still there are many oil to stay in residue, waste very big.
The final oil yield of squeezing process, the residual oil content reduced in residue are improved, is all the time the core of people's research
Content, is also one of difficult point of squeezing.The oil content of common sunflower seeds seed substantially between 17%-39%, also some kinds
Oil content is very high.The annual whole world is very big for the consumption of sunflower seeds seed oil, as far as possible the oil pressure in sunflower seeds seed squeezes out,

Oil yield can significantly be influenceed；Moisture content is too low, and residue is unfavorable for cake into cake after being unfavorable for squeezing completion, influence squeezing
Efficiency.
Preferably, the pre- oil content for squeezing the sunflower seeds seedcake for obtaining is 6%-16%.
The pre- degree squeezed is appropriate, and the oil content of sunflower seeds seedcake is too high, and overall oil yield can be reduced after two squeezinges, such as
The oil content of fruit sunflower seeds seedcake is too low, and screw oil expeller press chamber does not have grease lubrication, is easy for not block with regard to no thrust
Cake, not fuel-displaced, two squeeze the due effect that just do not have, and two to squeeze the sunflower seeds seed oil squeezed out very limited.After the pre- squeezing of control
Sunflower seeds seedcake oil content be 6%-16%, ensure that the Efficient Operation of two squeezinges, finally play raising oil yield, reduce
The effect waste, increased economic efficiency.
It is further preferred that pre- the squeezing takes off cake hydraulic oil press using automatic, the automatic de- cake hydraulic oil press
