"SCIENCE AND EDUCATION IN THE MODERN WORLD:
CHALLENGES OF THE XXI CENTURY"

The solvent losses % constitute 0,8-1,0% and cause environmental damage. Extraction oil is 
mainly used for technical purposes. The product that consumes extra gasoline as a solvent is 
unsuitable for use. The quality of the press and extraction oils deteriorated as a result of these 
changes.In the process of purification (refining) separated oil the productivity is reduced by the 
use of many alkaline. The resulting chocolate content is technically batter but has low nutritional 
value in livestock eg free protein (0up to 40% to 43%) free gossypol has a limited range of use 
since 0.02%. There is an important point large-scale enterprises suffer from raw material 
shortage and transportation problems under market conditions and small enterprise are not 
allowed to extract oil thought extraction methods. This is primarily associated with the capital 
investment need for the construction of spical equipment and secondly the problem of 
envirocmentalsabety and high sabety of fire sabety. This is primarily associated with the capital 
investment needed for the construction of special equipment and secondly the problem of 
environmental sabety and high safety of fire safety.Typically smaller enterprises generally use 
the following pressing method to achievie the maxsimum degreasing rate in the pressing 
method. 
1-foto An oil separation scheme for two step pressing. 
According to the method the seeds are smeared at 1 to about 55-60% with a mois-lure 
content of 11,5 to 17.0% and hydrothermal treatment to 70-80 degress Celsius.Then roas-ling 
boilers at 4-5 rations are fired at 4,51 5.6 % at a temperature of 105-110
0
C. In the press the 
prepared hings the primary oil is separated.The acidity of the crushed oil 2.0 mg BLOOD 15 
thhe girl is allowed to have free gossypol storage at a rate of 0.11-015%. After the first phase the 
fat content will remain up to 16-18% crushed grate in the grate.The progress of roasting is 
continued until the misture content of 3.0-4,0% at the temperature of 110-115 gradus and the 
expellers are separated from second layer of oil. The color of the black oil is 20 kg while the 
number of ocidadditienally is 2,5 mg and free gossypol must be less than 0.02% and the moisture 
content of the leaf should not exceed 6-7.In our studies, we dimed to prepare the toiling dough 
for oil separation ie, the preparation process and the method of pressing and extraction in small 
enterprises according to extract the gossipol from cotton seeds into oil and oil for this purpose 
the optimal variant of oil production process on the method of pressing and extraction in small 
enterprises from cotton seeds. 
-production of cotton seeds by cold pressing 
-the use of other sol vents instead of gasoline in the extraction of cotton seeds before 
pressing. 
-correct selection of extraction process
