Cottonseed oil extraction production line
Cottonseed oil, also called cottonseed oil for short, is also called cottonseed oil. Cottonseed oil refers to refined cottonseed oil. Under normal circumstances, unrefined cottonseed oil is not edible because cottonseed oil contains gossypol. Unhealthy impurities. Gossypol is a kind of birth control phenol, which has a greater impact on human fertility after consumption. Therefore, equipment manufacturers suggest that consumers, for their own health, and for the orderly development of the cottonseed oil industry, choose qualified national standard cottonseed oil for consumption.
Refined cottonseed oil is generally orange-yellow or brown. The fatty acid contains 21.6-24.8% palmitic acid, 1.9-2.4% stearic acid, 0-0.1% arachidic acid, 18.0-30.7% oleic acid, and 44.9-55.0% linoleic acid. The refined cotton oil removes toxic substances such as gossypol and can be used for human consumption. Cotton clear oil contains a large number of essential fatty acids for the human body, and it is most suitable to be mixed with animal fat for consumption, because the content of linoleic acid in cotton clear oil is particularly high, which can effectively inhibit the rise of blood cholesterol and maintain human health. The human body's absorption rate of cotton oil is 98%.
Cottonseed oil is divided into pressed cottonseed oil, leached cottonseed oil, genetically modified cottonseed oil, cottonseed crude oil, and finished cottonseed oil. The color is darker than other oils, and it can be used for human consumption after being refined. It contains a large amount of essential fatty acids for the human body and is most suitable for mixing with animal fat. However, eating crude cottonseed oil can cause damage to spermatogenic cells and lead to azoospermia
For processing cottonseed oil, suitable areas in China are naturally the main cotton producing areas, such as the Xinjiang cotton area, the Qinling cotton area, and the cotton area in the middle and lower reaches of the Yellow River, which are ideal places for investment in cottonseed oil. Abroad, Central Asia and other regions such as Uzbekistan, Turkmenistan, Kazakhstan, most of Africa, etc., are cotton producing areas.
Cottonseed oil is mainly produced from cottonseed kernels. Under normal circumstances, small cottonseed oil projects are directly pressed with the shell, but the overall oil output effect is not ideal. Cottonseed peeling, steaming, pre-pressing, extraction is cottonseed oil Ideal processing technology. .
In cottonseed oil processing, the advantages are obvious. If the output is small, then invest in the peeling and pressing oil production line, but the profit will not show up. In other words, since the cottonseed peeling machine is equipped, it is necessary to consider comprehensive The investment and operation cost, and the output profit, the larger the production scale, the lower the cost, and the cottonseed oil extraction process and the oil extraction production line can exert sufficient advantages.
In the cottonseed oil extraction production line, the oil content of cottonseed is not high, but the oil content of the cottonseed kernel after peeling is ideal. It can be used as a press steaming leaching production line, or the cottonseed kernel can be pre-pressed to extract part of the higher-quality pre-pressed oil. The pre-pressed cake is then sent to the oil extraction equipment for leaching, and then the pre-pressed oil and the leached oil are refined separately to obtain two kinds of oil, which can be sold according to different market needs.
The cottonseed oil extraction production line generally requires the use of special cottonseed screens, magnetic separators, shelling machines, shell and kernel separation screens, steaming pans, oil presses, pre-presses, and extraction workshops. All equipment configurations are based on the amount of cottonseed processed. Choose the production process of the extraction workshop, generally 30-100 tons, choose the conventional negative pressure extraction process, select the processing volume greater than 100 tons, choose the negative pressure evaporation extraction process, and then choose the corresponding refining equipment according to the output of cottonseed oil. Carry out refining production line, semi-continuous refining production line, continuous physical refining production line.
It can also produce dephenol cottonseed protein equipment according to market needs. It needs to be equipped with special equipment parts for softening pot, embossing machine, chain box extractor, extruder, and disc continuous dryer.
The cottonseed oil extraction production line requires a large investment. Users should be more cautious when choosing oil equipment manufacturers. There are many leaching oil equipment manufacturers, and users need to carefully screen them, and go to the market to investigate and see which equipment sells well. High reputation, and on-site visits to companies with strong intentions in two or three years, and comprehensively determine which manufacturer is more worthy of cooperation
In the cottonseed oil production process, after the pressing method is used, the oil contained in the cottonseed cake has not been extracted. The use of extraction equipment to extract the cottonseed cake can extract the residual cottonseed oil, which will reduce the cost of cottonseed oil manufacturers and reduce the cost of cooking oil. The use of the product has a very good effect, and design a suitable production plan process. It is the production guarantee that equipment manufacturing must provide
When the cottonseed cake is leached, the cottonseed oil and the solvent are mutually miscible, and the pretreated cottonseed oil is soaked or sprayed with the solvent to extract the cottonseed oil. The leaching method is used to prepare the cottonseed oil to make the The residual oil is low, the oil output rate is high, and it can save manpower and reduce the labor intensity of the operator.
When extracting oil from cottonseed cake, pay attention to the factors that affect the leaching effect of cottonseed oil. Whether the destruction of cottonseed cell tissue is sufficient, temperature and moisture will affect the leaching effect. It should also be based on the weight ratio of cottonseed and the solvent used. That is to say the solvent ratio. When producing leached cottonseed oil, engineers will provide technical training to the operators of the oil plant, so that customers can achieve good results in production.
When the cottonseed is leached to make oil, attention should be paid to steaming embryos with high moisture content. High-moisture steaming embryos should be used. As the water content of the embryonic material increases, it is conducive to the water absorption and rupture of the cottonseed color glands. The higher the moisture content of the embryonic material, the more damaged the glands. Full, and free gossypol is released. As the steaming temperature increases, a large amount of free gossypol binds to protein. If the moisture is insufficient when steaming embryos, the resulting bound gossypol may become denatured gossypol and dissolve into the oil. Using high-moisture steaming embryos, phospholipid hydrogel will reduce the chance of formation of gossypol and phospholipid complexes and reduce denatured gossypol. Opportunity for formation.
The cottonseed oil extraction production line is an advanced oil production method. For some oils, direct leaching is used, and the high oil content is prepared by pre-pressing cake leaching. In the production of cottonseed oil, the pre-pressing leaching process is used. The cottonseed cake obtained after the cottonseed is pressed is pretreated and then sent to the extraction equipment for extraction and oil production. Both the pressing equipment and the extraction equipment will affect the production efficiency and oil yield of edible oil. Good quality and advanced technology can increase the oil yield, but the oil yield is not high. Therefore, careful consideration should be given to the selection of equipment in order to obtain suitable production equipment and process plans.
Select cottonseed peeling, no-squeezing process, direct extraction of cottonseed tablets to extract oil, and the obtained by-products are then removed by methanol to remove gossypol to produce dephenolic cottonseed protein.
Dephenolic cottonseed protein is a high-protein product made from cottonseed after peeling, peeling, leaching oil at a low temperature and then removing toxic substances-gossypol.
Dephenolic cottonseed protein is a high-quality protein feed with crude protein content ≥50%, crude fiber ≤8%, and moisture content ≤6%. The main component of crude protein is globulin, about 90%, followed by gluten. Ultracentrifugation can obtain 3 globulins, 2S, 7S, and 12S, of which 2S exists outside the protein body, accounting for about 30%.
High dry matter content. Due to the unique processing technology, its dry matter content in the air-dried state is 93.6%, soybean meal is 89.6%, and ordinary cotton meal is 82.9%, which are 4 and 10.7 percentage points higher than soybean meal and ordinary cotton meal respectively.
High protein content. The protein content is higher than or equivalent to soybean meal, but higher than that of cotton meal and other vegetable protein sources. Compared with ordinary cotton meal, the content of crude protein (CP) and net milk production (NEL) increased by 31.95% and 19% respectively. % (Table 1.1), the crude protein content of soybean meal (cake), cotton meal (cake), sunflower meal, rape meal and flax meal are 40-45%, 36-45%, 30-33%, 33-37%, respectively And 31-33%.
