Determination and Estimation of the Influence of Different Types of Disturbances on the Thick Juice Colour to Apply in Automated Process Control Systems of the Sugar Mill Evaporator

The article considers the inefficient Ukrainian sugar mill operation and the influence of the evaporator automated process control system on energy efficiency of sugar beet production. Sugar production issues which decrease its competitiveness in Ukraine have been identified. Analysis about the impact of the major production departments has been carried out. The influence of the evaporator on the energy efficiency of the factory and on the quality of the products that must be competitive is proved. The study determined the influence of juice quality indicators during evaporation on the quality of sugar and the drawbacks in mathematical support of automated process control systems (APCS), which occur when evaporation conditions change. The article shows the ways to solve issues that happen within decreasing the product quality and inadequate regulation of the production efficiency by means of APCS when the raw materials quality during evaporation has not been taken account. It determines the issues in the work of automated evaporation process control systems. Because of the complexity of juice evaporation in the multiple evaporation station and the influence of various process indicators both technological and qualitative we determine the main vectors of the management at automated process control systems of juice evaporation. To solve the issue, the major criteria of sugar production efficiency, regulatory requirements, theoretical foundations and the practical experience of implementation and the use of quality criteria in APCS in countries using the energy efficient and competitive technologies of sugar production are considered. The efficiency of the proposed product quality criteria for mathematical support of automated evaporation control system is substantiated. Accordingly, there is reason to think that the obtained qualitative criterion of efficiency can be used in mathematical support of automated juice evaporation process control systems at the sugar factory.
