The qualified decolored oil Screw Hydraulic Oil Press machine enters into the spiral plate heat exchanger to recover most of the heat, and China Cheap nut oil extraction machines price next goes to high pressure steam heat exchanger to be heated to the process temperature (240-260°C) and then enters the deodorization tower. Shandong Leader Machinery Co.,ltd. The upper layer of combined deodorization tower is the packing structure which Screw Hydraulic Oil Press machine is mainly used to remove the odor producing components such as free fatty acid (FFA); Shandong Leader Machinery Co.,ltd. the bottom layer is the plate tower which is mainly for achieving the hot decoloring effect and reducing the peroxide value of the oil to zero. Screw Hydraulic Oil Press machine Oil from the deodorization tower enters into the heat exchanger to recover most of the heat and makes further heat exchange with crude oil, and then is cooled to 80-85°C through the cooler.

Many vegetable oils are consumed directly, or indirectly as ingredients in food – a role that they share with
some animal fats, including butter and ghee. The oils serve a number of purposes in this role:
Shortening – to give pastry a crumbly texture.
Texture – oils can serve to make other ingredients stick together less.
Flavor – while less-flavorful oils command premium prices[citation needed], some oils, such as olive, sesame,
or almond oil, may be chosen specifically for the flavor they impart.
Flavor base – oils can also "carry" flavors of other ingredients, since many flavors are present in chemicals
that are soluble in oil.
Secondly, oils can be heated and used to cook other foods. Oils suitable for this objective must have a high
flash point. Such oils include the major cooking oils – soybean, canola, sunflower, safflower, peanut, cottonseed,
etc. Tropical oils, such as coconut, palm, and rice bran oils, are particularly valued in Asian cultures for high
temperature cooking, because of their unusually high flash point.

1.Automatic production process of nut oil extraction machines
2.Pretreatment:
Because many raw materials need to be cleaned. So There are many machine to cleaning, separation and so on.
3.Extraction:
Solvent extraction fits for pre-press extraction of high-oil-content materials and direct once time extraction of low-oil-content materials.
4.Refining
Degumming:We are using a special wet degumming,Thorough removal of colloid. Improve the quality of rice bran oil.
Decoloring :Premixing the a certain amount of clay with 20% degumming oil in the premix tank , then using the oil pump
pump the premixing oil and the rest 80% oil in the vacuum decolorization tower to get rid of the pigment,then using
platetype filter to separate the oil and the waste clay.
Dewaxing:Wax affects the taste of the oil and it's transparency.Poor solubility in oil, cannot be absorbed by human.
Deacidification /Deodorization:Avoid large amounts of neutral oil accident losses, using high temperature and high
vacuum environment, by using the method of steam stripping deodorization, removing acid.
Degrease:Different from other oil,rice bran not only exists wax,but also exists fat at low temperature.Effective
separation of solid fat are more critical in the process
5 . Advantages of nut oil extraction machines
(1) High oil yield , obvious economic benefit .
(2) Lower residual oil rate in the dry meal .
(3) Improving the quality of the meal .
(4) Low processing cost , high labor productivity.
