Abstract

The existing technology for the purification of diffusion juice and its hardware design has not fundamentally changed over the past four decades. The lack of the necessary theoretical developments and experimental data hinders the development of existing and the development of new technological processes. Therefore, the main direction of improving the purification efficiency of juices of sugar beet production is the disclosure of its unused reserves and their implementation in practice. The scientific problem of choosing the rational direction for improving the technology of juice purification, which ensures the production of consumer granulated sugar in the face of changes in a wide range of quality of raw materials, is relevant and has important economic importance, especially in the context of the transition of beet sugar factories to a market economy. One way to solve it is to make fuller use of the adsorption capacity of calcium carbonate particles while increasing the filtration properties of saturation sediments. Therefore, the study investigates the effect of cavitation effects – vapor condensation and hydrodynamic processing of diffusion juice on the processes of purification of diffusion juice, juices of preliminary defecation, first and second saturations. The analysis of the influence of various effects of cavitation processing of juices from the point of view of improving the purification efficiency, the optimal place of the purification process in the technological scheme of production is established.

Highlights

Classical methods of intensifying the processes of calccarbon dioxide purification of diffusion juice of sugar beet production by changing the temperature, alkalinity, or duration of individual stages do not provide an increase in the purification efficiency
The deposition rate during the processing of diffusion juice in a hydrodynamic cavitation device compared with the conventional method increases by 19.4%, and the sediment volume decreases by 14%
The sedimentation rate of preliminary defecation juice after processing diffusion juice in a vapor condensation cavitation device increases by 15.6%, and in a hydrodynamic cavitation device by 21.8%, the volume of juice sediment decreases in both cases by 12.9%

Summary

Introduction

Classical methods of intensifying the processes of calccarbon dioxide purification of diffusion juice of sugar beet production by changing the temperature, alkalinity, or duration of individual stages do not provide an increase in the purification efficiency. As can be seen from the experimental data, cavitation processing of diffusion juice intensifies the processes of coagulation of substances of a colloidal dispersion of diffusion juice at the previous defecation and adsorption of non-curvatures at the stages of the first and second saturation, as evidenced, in particular, by an increase in the purity of purified juice by 0.7%.
