USING THE SECONDARY RAW MATERIALS OF GRAIN PROCESSING AND OIL SEED RECYCLING AIM TO INCREASE OIL REFINEMENT EFFICIENCY

In the article the expert analytical review of literature sources on the basis of set tasks on realization of the purpose of increasing the efficiency of safflower oil purification using secondary raw materials of grain and oilseed crops processing is carried out, the object of research and the purpose of technology of effective purification of safflower oil are defined. Methods of using secondary raw materials as filtering materials were analyzed, linen fiber is proposed as an optimal filtering material. Multifactorial experimental studies were carried out for the application of filtering material consisting of recycled processing raw materials in industrial equipment. We saw that when purification with filter media composed of recycled recycled processing raw materials, the safflower oil yield increased due to pump pressure. Under the influence of the pump pressure of 180-10-3 Pa, we can relate that the oil yield decreased and the capacity of the filter media decreased, and we can see that the safflower oil yield also increased due to the increase in filtration rate. As a result of filtering safflower oil through linseed fiber in a frame filter with a filtration rate of 0.1 L/s, the safflower oil yield increased to 93%. As a result of the study of fatty acid, inorganic composition and the amount of vitamens of safflower oil, we see a decrease in the content of saturated fatty acids and an increase in the content of mono- and polyunsaturated acids (oleic, behenic, cis-10-heptadecenoic and cis-linoleic acids), and we also observe that the inorganic composition meets all the norms, and the content of vitamin E increases.
In the research work, frame filter press of FPR brand is used for purification of vegetable oil. As a result, the parametric dependencies of effective purification of safflower oil using filtering materials consisting of secondary raw materials of processing in a frame row filter press are substantiated and a rational solution for application in production is found.
