CHALLENGES OF THE XXI CENTURY" NUR-SULTAN, KAZAKHSTAN, JULY 2019 15 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 |
