Model of a Sugar Factory with Fully Automated Production of Amino Acids and Amino Acid-Pressed Beet Pulp Pellets

Résumé

Abstract The key factor in the industrial production process for the manufacture of the amino acid from the sugar industry is the industrial scale-up. To investigate the impact of the different geometry and physical conditions parameters on an industrial process several techniques such as computational fluid dynamics and scale down approaches have been applied. Process modeling can support the design and the optimization of all these processes. Model, considering the process operative parameters and process stoichiometry, using the data from Egypt Sugar Industry, give an estimation of the process efficiency, the product quality, selectivity as well as the condition for an optimal yield. Combining the results obtained by the model with the data obtained by the scale down devices, the optimal process configuration was identified in an early phase of development to achieve that not only the valuable amino acids can be recovered from soft beet juice, but also the fluid sugar simultaneously satisfies all requirements for the subsequent processes of sugar manufacturing. In this case, the choice of an ion exchanger is associated with the development of a method for extracting amino acids based on the study of the dynamic patterns of sorption and desorption, depending on a number of factors. These include: the shape of the ion exchanger, the degree of its granulation and cross-linking; parameters of ion-exchange columns; flow rate and temperature of working solutions; efficiency of the eluent. Furthermore, for maximizing the utilization of the amino acids extract was added to the beet pulp for producing amino acid-pressed beet pulp (APBP) to be used as integrated animal fodder with highly nutritional value and subsequently high marketing value. The obtained results were indicated the overall recovery yields of 17 amino acids extracted from beet juice were 5.85% respect to dry substance and the percent of the elimination were 98.5%.
