Abstract

Manufacturers prefer berries and fruits, but there are also other products made with seeds, aromatic and medicinal herbs, spices, as well as other components. The main production stage for obtaining tinctures and aromatic alcohols is the extraction process. Currently, a large number of designs of extractors for solid-liquid system of periodic and continuous action have been developed. All of them are different from each other in terms of efficiency, energy consumption and applicability in a particular production. The purpose of this work is to study and analyze the influence of the structure of raw materials on the efficiency of extraction in equipment of various types. To carry out the research, three types of raw materials were selected from various groups: rose hips, penny root and chaga mushrooms. The most suitable and promising extractor designs are the Soxlhet extractor; centrifugal extractor; rotary-pulsating apparatus. The results of the work, it was concluded that the most versatile apparatus is the rotary-pulsating apparatus, since during its operation the raw material is crushed. Plant raw materials give the most complete target components with list time. In devices of similar designs, the different internal structure of raw materials does not affect the quality of the extracts obtained.
