Автоматизація пастеризації яблучного соку

Abstract

Health is an invaluable property of not only every person, but also society. To maintain human health at a certain level, it is necessary to include fruit and vegetable juices in the diet, including apple juice, which has high consumable properties. The preservation of these properties can be provided only due to the automatic control of the technological process of production of apple juice. Automatic control of the process of pasteurization of apple juice is one of the most complex and important tasks, since it provides compliance with the technological regulations of heat treatment of apple juice. The process of pasteurization of apple juice as the control object is a complex dynamic system. An analysis of existing automatic control systems for the pasteurization of apple juice demonstrates certain disadvantages and puts the task of the following development. In the Odessa National Academy of Food Technologies, the automation of technological processes and robotic systems has been developed by a new method of pasteurization of apple juice, using a cascade system of automatic regulation, which reduces the delay in the patient control circuit, which increases the quality of the finished product, process performance and reduces its energy intensity. The results of structural-parametric synthesis and analysis of the developed automatic control system confirm the benefits of the proposed approach. The constructed cascade system of automatic regulation provides a high dynamic accuracy of management of the considered technological process. The automated workplace of an automated operator-technologist and an automatic control system in the SCADA system allows you to conveniently and operate and control the process of pasteurization of apple juice. Further development of the automation of the process of pasteurization process of apple juice will find in master's graduation work.
