An important role in solving the problem of full use of raw materials should be played by the organization of rational processing of plant raw materials into extracts for use in the production of food and medicinal additives. In Uzbekistan, about 16200 thousand tons of fruits, grapes, and melons are grown annually. From them comes from 2 to 10% of seeds and seeds, which contain valuable biologically active substances in their composition. Currently, there are no installations for deep processing of seeds and seeds with low productivity in the processing industries of small businesses and farms in Uzbekistan. In this connection, the waste of apricot fruits, grapes and melons is not processed in order to obtain biological raw materials used in the pharmacopeia and for the enrichment of vegetable oils. The purpose of this study is to experimentally determine the ratio of the solvent to the raw material (hydro module) since it significantly affects the energy costs and productivity of the extraction plant. The aim of the study is to conduct tests as a single-factor experiment to determine the effect of this factor on the yield of the extract. The solution “ethanol + water” was used as a solvent, the range of changes in the hydro module was adopted from 2.0 to 3.2. The device and the principle of operation of the experimental installation, the method of conducting the experiment is given. Mathematical and statistical processing of the experimental results was carried out and a regression equation was obtained. The analysis of the results of the experiments showed that the rational value of the hydro module is 3, under the same conditions of the crushed core 0.3-0.35mm, the initial moisture content of the raw material 7-8% and, the temperature of the extraction process 600C.
