The article shows that for the essential oil industry of the Russian Federation to solve the problems of import substitution it is urgent to develop effective technology to extract fatty oil from the crushed and deprived of ether by water vapor coriander fruits. The existing technologies for obtaining fatty oils from deprived of ether coriander were considered. It is shown, that at small-scale enterprises it is most advisable to remove fatty oil by screw pressing. A brief analysis of main factors affecting the completeness of oil extraction in screw presses was carried out. The conclusion about the necessity of preparation of deprived of ether coriander for extraction with the purpose of increasing the yield of fatty oil was made. It is shown, that one of the stages of such preparation is the removal of part of the shell from deprived of ether coriander, which also increases the nutritional value of the oilcake. Fractional composition of deprived of ether coriander after extraction of essential oil by water vapour and drying was investigated by sieve analysis method. On the basis of obtained data, prior to separating the shell by pneumatic separation, it is recommended to separate deprived of ether coriander into three fractions by size – coarse (riddling from the sieve with the diameter of 1.8 mm), medium (riddling from the sieve with the diameter of 1 mm) and fine (undersize from a sieve with a diameter of 1 mm). Component composition of the coarse fraction of deprived of ether coriander was studied. It was found, that the content of the shell in this fraction is 36%, which indicates the possibility of its effective separation by pneumatic separation
