- Abstract
Raw coriander, which is mainly produced by the Russian Federation, contains 1.62-2.40 % of essential oil and up to 28.5 % of fatty oil. Essential oil is a product of coriander seeds processing, in which the content of the most valuable component linalyl ester (monoterpene monoatomic trisubstituted carbinol with the scent of May lily) should be no less than 65 %. Geraniol and geranyl acetate also belong to valuable components of coriander essential oil, while camphor is undesirable. Anatomic morphological structure of coriander fruits, which consist of two mericarps and essential-oil receptacles on their inner surface, leads to their splitting during the transportation and post- harvest losses of essential oil amount to 23.4 %. The most rational operating modes of basic equipment, a separator, have been established for the previously developed method of separation of raw coriander and simultaneous fractionation into whole and split fruits with the help of a sieve with a mesh-size 2×20 mm, with primary processing of split fruits and the production of more valuable essential oils. The determined operational modes are the following: the vibration frequency of a sieve box which is 400 vibrations/min, the vibrational amplitude of the sieve box is 8mm, the sieve inclination angle is 8 degrees, a layer of raw materials is 5mm tick. The principal flow sheet of production line for implementation of innovative technologies in industry has been developed where Russian equipment is used. The developed innovative technology and the principal flow sheet of the production line allow dividing initial raw coriander into two fractions of whole and split fruits with efficiency up to 91, 8 %, which improves the cleaning efficiency of raw coriander from foreign impurities to 96.8 % in the fraction of whole fruits and up to 73.8 % in the fraction of split fruits, while in generally accepted technology the cleaning efficiency is from 36 to 51 % for overall raw materials. That allows producing essential oils from the fraction of split fruits with higher content of valuable components.
