Abstract
<p>This paper presents the main theoretical elements underlying the process of dimensional separation of the fragments of chopped medicinal plants. To sort chopped plant mixture from the same medicinal plant, there are used vibratory classifiers with plane sifters, which are the active working body. Case studies were conducted and there were analyzed, based on numerical applications, the movements of plant fragments on a classifier with linear vibrations along the sifter, existing in practice. Numerical simulation has provided information on trajectory parameters of the jump of a plant fragment on the vibratory plane sifter, useful elements in the theoretical grounding of the equipment workflow. </p>

INTRODUCTIONThe quality of herbal products obtained from the processing of medicinal plants depends on the quality of raw medicinal plants and the quality of primary and/or advanced processing products.The sequence of operations in primary processing of medicinal plants is mainly determined by raw material (species, plant organ, etc.) and the purpose of their exploitation (packaging and marketing in the form of teas, storage or further processing in various industries) [1]
The quality of herbal products obtained from the processing of medicinal plants depends on the quality of raw medicinal plants and the quality of primary and/or advanced processing products.The sequence of operations in primary processing of medicinal plants is mainly determined by raw material and the purpose of their exploitation [1].Sorting is the operation of separation in several fractions (3, 4) according to certain criteria: size, weight, color, etc., of the components of a mixture of agricultural products found in the state of granules, fragments, particles, pieces, etc
Based on the theoretical study of the literature on the kinematic regime of sifters and knowing some of the constructive and functional parameters of plant sorter, was made a theoretical calculation, which characterizes the behavior of plant fragments in the sorting process on plane sifters with longitudinal oscillations
Summary
The quality of herbal products obtained from the processing of medicinal plants depends on the quality of raw medicinal plants and the quality of primary and/or advanced processing products.The sequence of operations in primary processing of medicinal plants is mainly determined by raw material (species, plant organ, etc.) and the purpose of their exploitation (packaging and marketing in the form of teas, storage or further processing in various industries) [1]. The oscillatory movement, characterised by frequency and amplitude of oscillations, occurs in a direction forming an angle α to the plane of the sifter [5,6,7] Characteristic of these sorting surfaces is that particles movement on the sifter surface takes place in jumps [810]. Following are presented the equations of movement of a plant fragment on a plane oscillatory surface taking into account the two main directions of movement (Figure 2), downward (Figure 2 a) and upward (Figure 2 b). In this case, the movement equation of the fragment is given by:. - Coordinates of point A; As it can be noticed in Figure 3, point A is the maximum point of fragments trajectory function (equation (35)), : dy dx v
