Cottonseed Oil Production line introduction
Cottonseed Oil Pretreatment and Pressing Processing Line Process:
Cleaning It use the high-efficient cleaning screen， specific-gravity destoner and magnetic separations to reach the best cleaning efficiency,after cleaning, the cottonseed will have minimal impurities.
Shelling machine/crushing machine The tooth roller crusher has a pair of tooth rollers to remove the shell. The material go into the tooth roller by the feeder, the speed and difference and the pressure between the pair rollers can cut and extrude the sunflower seeds, the shell will change shape and be crushed.
The machine rollers are high strength alloy steel gold roller, long service life, good effect wear-resisting, easy to maintain, and the spare parts are easy and cheap to get.
Shell and kernel separating screen Cylinder beating screen rotate in different speed and direction. There are several beating sticks on the axle, the end of the beating stick closed to the cylinder’s inner wall is inclining, it has the function of beating and pushing. Through the screen hole the sunflower kernel can be separated.
The machine use the high strength screen. It has the advantage of reasonable design structure, best separation effect, high working efficiency and so on.
Flaking The propose of flaking is broke the cell tissue of the cottonseed, separate the oil easily. It use the alloy flaking roller, the service is twice than the normal roller.
It is automatic hydraulic roller adjusting system, can guarantee the thick-even(≤0.3mm).The whole machine seal good efficient.
Roasting Use layer type roasting machine, each layer the mixing wings from the bottom is 5mm, it avoid that the material stay on the bottom and mixing unevenly. The whole cattle is sealed, thus can keep the space upon the flake material has maximum moisture, can guarantee the flake material fully and evenly roasted.
Expanding It is composed by frequency conversion feeding system, expander cylinder, extruding auger, steam adjusting system, electric control cabinet and transmission.
Filtering Use the automatic slag-discharging filter to avoid manual cleaning the filter cloth with high efficiency. The filtered oil slag go to recycle-press automatically,which section also has clarification slag-dredger to guarantee the crude oil has minimum slag residue and also guarantee the effect of the following de-gumming section.
Drying machine The drying machine is layer structure, when the steam enters the machine, it will remove the moisture and increase the temperature for the material to reach the best condition for extraction.
Conveying machine The conveying equipment is good working performance, best sealing effect. The motors and reducers are Chinese famous brand.
Cottonseed Oil Extraction Plant Process:
Cottonseed oil extraction production line solves crude oil extraction from cottonseed cake through processing flows of solvent extracting, mixture oil filtration, wet bran treatment of dephenolizaiton and mechanical desolvent, and low temperature drying, evaporation, gas stripper to obtain crude cottonseed oil.
Oil solvent extraction method is using organic solvent through soaking or spraying contact methods to dissolve oil contained in the oilseed (pressed cake, flake, expansion material) by oil extractor, and then the oil will be separated from the solvent by a series of evaporator, condenser, stripping tower etc. The wet meal within less than 1% oil will be further processed by the desolventizer-toaster/DTDC to remove the solvent and obtain the product extracted meal.
The solvent oil extraction method have many advantages than the direct pressing method, such as after extracting, it will have low oil residual( extraction oil residual is < 1%, direct pressing oil residual is about 7%), low labor intensity, better work environment and better cake quality etc.
Brief Introduction of Cotton Seeds Oil Refinery Plants:
Oil Refining is a progress of removing the impurities such as phospholipids, FFA, pigment, off-flavor in cruel oil before edible application. Oil refining machine is used for producing the first or second grade edible oil. We are able to supply the professional oil refining plant and related oil refining equipments. With high degree of automation,the oil refining machinery can refine 20 kinds of oil, such as soybean, rape seeds, peanut, etc. in a small production line or in large oil plant.

Thanks for this information. I've got oil machines at https://bronto.ua/en/ and going to grow my sunflowers to get oil from them. I suppose to do everything right because it's very important to make a sunflower oil with high quality.
