CERCETĂRI PRIVIND PROCESELE DE DETAȘARE ȘI SEPARARE A FRUCTELOR DE CĂTINĂ CONGELATE DE PE RAMURI

Abstract

Following the bibliographic and theoretical research carried out by the specialists of INMA Bucharest Institute, as well as the experience of sea buckthorn producers and processors, the experimental model of a high-performance equipment for separating frozen sea buckthorn fruits from the harvested mass (branches, fruits and leaves) was designed and made. Thus, the subject of this paper is the experimental research carried out on an improved equipment for detaching and separating frozen sea buckthorn fruits from the branches - ESFC. After an introduction in which the current state in the field was highlighted, the tested equipment was presented with the main functional parameters, adjustments necessary to obtain an optimal working regime suitable for the processed raw material. Following the experiments carried out, the main working indices of the equipment were determined, among which: the working capacity, the degree of separation of the fruits from impurities as well as the optimal functional regimes. Following the tests carried out, in two variants of arrangement of the paddle arms on the separation rotor, some conclusions were formulated, the most eloquent of which was that, for the equipment tested in Variant II equipped with the separation rotor, the highest values for the feed flow resulted for the angle of inclination of the paddle of 450 and the rotation speed of the rotor of 90 min-1 and a high degree of separation.
