High quality ground nut sunflower and cotton seeds oil pressing machine
Company information
XinxianLDD Chemical engineering equipment co,. Ltd is mainly focused on all kinds of pressure vessel and machine manufacturing .It is established in 1978 and has much rich experience in this field . .And our best seller is peanut oil machinery .We produce the complete oil production line ,and sell to all the world ,such America , Middle east ,Africa ,Europe etc. 
Generally making oil process are as follows:
1) The first stage is clear, then the shell,cooking,press and extraction process.Through cleaning can reduce the loss of oil, improve the yield efficiency, improve the quality of oil and cake, and increased the capacity of equipment, reduce the mechanical wear and tear, avoid accidents, reduce the fly ash, that is conducive to environmental protection.
(2) Softening is broken for larger particles, or through controlling small particles of oil material degree of moisture and temperature making the oil material has the appropriate plasticity, facilitate flaking and steaming and cooking, the cooking average temperature is between 60 to 70 degrees Celsius.Flaking is conducive to the destruction of the fuel cell structure, easy to take out the oil from the cell. 
(3)The extraction is the process that oil by solvent from plants seed .Extraction is that making the solvent molecules penetrate into fuel oil form mixture (mixture) of a solution, then making mix the oil with solid residues (cake) separation,recycling the solvent the using the boiling point of different oil for evaporation. Finally the refining oil flue from the stripping tower. 
RefiningDeacidification Sodium hydroxide antagonize free fatty acids, and subside phospholipids, to remove the insoluble impurities, the after the separation of soapstock, neutral oil was washed in soft water, last drying in vacuum. Decoloration 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. Dewaxing can ensure the colour of 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. Deodorization Using high temperature and high vacuum steam stripping method deodorization temperature commonly 180, vacuum degree 9.3 104 Pa can achieve ideal results.
Packaging & ShippingPacked by the protect film inner, water-repellent plastic outside. The wood packing is necessary if send by less than a container. Cold press castor oil machine will fixed by steel rope in the container.
