ON-LINE PROCESS CONTROL UNIT MANUFACTURING INDUSTRY

摘要

Agriculture and agro-based industries form the backbone of Indian economy but they are still adopting traditional methods. Jaggery industry is an important agroprocessing industry in rural India. The major constraint in this industry is lack of standardisation in processing. In traditional method of jaggery manufacturing a so-called skilled person known as "Gulvaya" plays a deciding role in clarification of sugarcane juice and in confirming formation of 'Kakavi' (liquid jaggery) and jaggery. The presently developed microcontroller based on-line process control unit is field usable and can give audio indication of important parameters (pH and temperature) and display the parameters in decimal form on the LED numeric display. It has resulted in giving us a precise results, in order to produce a superior quality jaggery.
