Justification of the Energy Efficiency of the Technology for the Thermochemical Preparation of Beet Chips for the Extraction of Sucrose Using Exergy Analysis Methods

Statistical studies of the last five years indicate a steady increase in the consumption of high-carb foods, an important place among which is confectionery and white sugar. These products make up a significant part of the diet of a modern person, due to their high taste and the ability to quickly saturate the human body with energy.

Sugar production is an important part of the food industry of the agricultural complex of Russia, the products of which are in high consumer demand, both among the population of the country and among various sectors of the food industry. Significant volumes of processed sugar beets, a plurality of technological operations and the energy capacity of this food production require the timely introduction of advanced technologies that can save energy and resource-saving efficiency in the face of rising energy prices.

In the technological flow of sugar beet production, a significant amount of heat and electric energy is concentrated on the site of extraction of sucrose from beets, necessary to maintain optimal parameters of the diffusion process. A significant number of operating enterprises in the Russian sugar industry carry out the extraction of sucrose using traditional technological solutions into an inclined type apparatus. Traditional technological methods do not allow to provide the standard value of its extraction and need technological improvement.

A technological solution has been developed to improve the traditional technology for the diffusion extraction of sucrose from beets using the thermochemical processing of beet chips before it enters the diffusion apparatus, and an exergy analysis of the proposed development has been carried out. By calculation, the results of experimental studies on the effectiveness of the thermochemical processing of beet chips are confirmed, and the feasibility of using an exergy calculation to assess the thermodynamic state of the heat-technological processes of beet sugar production.
