Efficiency of low quality beet processing

In recent years, the annual processing of sugar beet in Russia is 45 million tons or more, which allows to produce white sugar in the amount of 6.0 million tons or more. during the production season, the quality of beets does not remain constant – not only its sugar content changes, but also the content of harmful soluble non-sugars, as well as physical and chemical parameters - the mass of root crops decreases due to wilting, reducing turgor, respiration and germination, rotten mass appears as a result of microbiological and enzymatic processes and the formation of foci of mucous bacteriosis. One of the main tasks of improving the diffusion process is to increase the elasticity of beet tissue and reduce the intensity of the transition of pectin substances into the diffusion juice. This goal is achieved by using effective chemical reagents in the composition of the feed water introduced into the diffusion apparatus, as well as processing of beet chips immediately before the sucrose extraction process; reducing the temperature of desugarisation of beet pulp in the diffusion apparatus in the allowable interval. The method of intensification of sucrose extraction using the method of treatment of feed water in an electric field is proposed. Improvement of the dispersed composition of the resulting sediment particles is facilitated by the return to the preliming of the carbonate suspension of juice II saturation, carried out using an activated suspension of filter perlite. The homogeneity of calcium carbonate particles and correspondingly high filtration rates of saturation juice are formed due to the active circuit of the internal circulation of the juice. The use of the proposed recommendations during the implementation of technological processes in their implementation in modern equipment of the diffusion process and purification of the obtained juice allow to minimize the negative consequences of beet processing both at the initial stage of the production season when technically not ripe root crops are received, and during the end of the season when processing raw materials of reduced quality.

The article presents the results of a study of the influence of raw juice obtaining methods, namely, using an extractant, acidified with sulfuric acid with the addition of a suspension of freshly prepared gypsum, and using an extractant, treated with sulfur dioxide, as well as subsequent treatment of obtained thin juices with sulfur dioxide before evaporation on the color of sugar beet processing intermediates. A brief description of methods to reduce intermediates color used in sugar industry–sulfitation, ion-exchange and active carbon treatment is given. The advantage of intermediates treatment with sulfur dioxide compared with treatment with ion exchange resins and activated carbon is theoretically justified. The methodology for setting up laboratory tests is given and substantiated. The color indicators of raw juices, thin juices and obtained thick juices are given. It was established that a single treatment of intermediates with sulfur dioxide at the stage of raw juice obtaining provides a decrease in thick juice color by 7.11 %, a single treatment before evaporation–by 29.70 %, and a double treatment at the stage of raw juice obtaining and before the evaporation station–by 38.37 %.

Long-term storage of large volumes of sugar beets, due to an increase in the production capacity of enterprises, leads to a decrease in the technological quality of raw materials. Unstable weather conditions cause freezing and subsequent thawing, which destroys beet tissue, increasing its accessibility to microorganisms. Processing of substandard raw materials is accompanied by the use of a whole range of bactericidal drugs at different stages of production, to which resistance of the accompanying microflora develops over time. To reduce the degree of infection of intermediate products at the production site, it is proposed to use a bactericidal preparation based on the sodium salt of dichloroisocyanuric acid (DCCN), which can be introduced into the extractant before feeding it into the diffusion apparatus. The influence of the quantity, concentration of the DCCN solution and the temperature of the extractant on the qualitative characteristics of diffusion and purified juices was experimentally established. A positive effect of DCN was revealed during the processing of beets contaminated with Leuconostoc mesenteroides. Using mathematical modeling methods, regression dependencies were obtained that reflect the relationship between process parameters and quality characteristics of juices. The optimal parameters for the use of DCCN in preparing the extractant for the diffusion process have been established: temperature 65 °C, concentration of the DCCN solution 0.05 %, its amount 15 %. This drug can also be used at the stages of storing sugar beets, processing beet chips before extraction, and disinfecting equipment.
