INVESTIGATIONS OF HYDRODYNAMICS AND HEAT EXCHANGE IN REMOTE HEAT EXCHANGE ELEMENTS OF EXTRACTORS

Abstract

This article discusses innovative methods of extracting oil from vegetable raw materials. Due to the man-made load on the environment, many studies are aimed at researching new and improving old methods of extracting useful components from raw materials. Innovative methods must be not only resource-saving, but also environmentally friendly. That is why modern market requirements are aimed at developing the production of environmentally friendly and better products of the pharmaceutical and biotechnology industries. Among such products a significant amount is biologically active substances (BAS), which are produced from plant raw materials. The volumes of vegetable raw materials in Ukraine allow us to speak about the huge potential for obtaining valuable components of plant materials. Improving the production of various products based on innovative methods of technological processes is a necessary prerequisite for the development of modern industry. One of the problems to be solved by innovative methods and technologies is the maximum extraction of useful products from raw materials. In particular, this applies to the production of oils, which is used not only as a necessary food product, but also as a raw material for biofuels. Due to a number of advantages, the process of ultrasonic extraction is considered. An ultrasonic extractor with a remote heat exchange element is presented. To improve this device, it is proposed to change the heat exchange element such as "pipe in pipe". The simulations and calculations performed in the ANSIS program confirm that the proposed coil-type heat exchange element significantly affects the temperature of the extractant at the outlet, and hence the time of the extraction process.
