New technology of postharvest processing of coriander

Technology of post-harvest processing of raw coriander, including stage-by-stage purification from impurities by fractionation on whole and split seeds and their further separate processing, has been developed. The object of the study was the composite sample of industrial raw coriander, obtained at the processing plant. The fractional composition of industrial mix of coriander is studied and sizes of its components by the arithmetic mean value of their thickness and the root mean square deviation of the analyzed values for each component are defined. It is found that whole seeds can be separated from the split ones on the sieve with rectangular holes 2 x 20 mm in size. The degree of allocation of whole seeds is defined by normalized function of Laplace. The coefficient of completeness of separation is calculated. For the industrial mix of coriander by scratch fraction for whole seeds it was 0.9472. The figures of purification and fractionation for raw coriander with humidity being not more than 12% were obtained in laboratory conditions on the stand separator by sieving with a rectilinear inclined vibration of the sieves (the oscillation frequency of 400 vibrations/min, amplitude ? 8 mm, the angle of inclination of the sieve ? 8 degrees, the thickness of raw material layer ? 5 mm). Structural scheme of new technology of post-harvest processing of raw coriander is presented. It allows to increase the efficiency of cleaning of raw coriander from impuritiesSourcesNew technology of post-harvest processing of corianderPelipenko, T.V. Mustafaev, S.K. Usov, A.P.
