DISCRETE-PULSE INPUT OF ENERGY AS INCREASE IN THE EFFICIENCY OF SUGAR PRODUCTION
Abstract
The article describes techniques and technologies of domestic sugar production, technologies for obtaining and subsequent purification of diffusion juice. The use of discrete-pulse energy input is proposed to increase the efficiency and improve the purification of the diffusion juice.
The efficiency of sugar beet raw material processing largely depends on its quality, production technology and subsequent purification of the diffusion juice. The current state of equipment and technology of domestic sugar production does not ensure the sufficient completeness of sucrose extraction from beets, highly effective lime-carbonic acid purification, as a result of which it does not ensure the achievement of world average indicators. The solution to these problems is the improvement of the existing and the creation of innovative technologies for sugar beet processing using the method of discrete-pulse energy input (DPEI).
The technological results of the verification of the method of saturation in the RPA confirmed that with the same energy consumption, expressed by the turbulent dissipated energy, the pulsating effects are more effective than the stationary process. At the same time, part of the energy goes to the formation of the dispersion surface and, mainly, its recovery, which compensates for coalescence, and the other part goes to the deformation of this surface under the action of turbulent pulsations.
The application of the DPEI and RPA method for its implementation in the sugar industry allows the processes of mixing, dispersion, dissolution, heating, and homogenization to be carried out simultaneously in one apparatus. Rotor-pulsation devices can replace cavitation devices, homogenizers, dispersers, because when passing through their working organs (stator-rotor), the liquid is exposed not only to cavitation, but also to the action of shock waves, interphase turbulence, penetrating cumulative microcurrents, eddies, which causes interphase Rayleigh-Taylor or Kelvin-Helmholtz instability surfaces, which leads to intense crushing of dispersed inclusions, an increase in the total contact surface of the phases, and an increase in heat and mass transfer processes. Similar effects are unattainable when using traditional cavitation devices.
