Title-An Integrated PC based Tea Process Monitoring and Control System

                     Research contribution:


  • Tea Industry automation:

He is actively engaged in the field of Application of Electronics, Instrumentation and control in tea industry since he started his PhD work in 1994. His research outcomes generated concepts of innovations in Instrumentation and control for the benefit of tea industry of the country. The conventional quality monitoring concepts are envisioned by him with new horizon of electronic controls. As a result he could practically implement his designs on experimental basis in two tea estates viz Chinnamora Tea Estate, Jorhat, Assam and Noor-Bari Tea Estate, Tezpur Assam.


  • E-Nose development for tea tasting:

Recently his team developed an Electronic Nose (E-Nose) setup at Tezpur University indigenously which can classify and distinguish various tea flavours .This setup costs far less than a commercial E-Nose setup while the performance is fairly comparable with commercial systems. This is the first indigenously developed E-nose setup in the country as claimed by the team.

Significant contribution is reflected in his challenge to develop an E-Nose setup of comparable capacity to a commercially imported setup costing to the tune of USD 50,000. Apart from opening up a new area of electronic tea tasting, the researchers and students of this university and the region are motivated and exposed to this new and emerging technology by this setup.

A low cost portable Tea flavour detection system has been developed  using  PIC microcontroller based embedded system.


  • Tea colour matching:

Moreover a computerized colour matching technique for tea fermentation has also been developed and the trial run was successfully conducted at Noor-bari Tea Estate, Tezpur Assam.


  • Neuropathy Detection

A PC based  peripheral neuropathy detection technique has been developed using ANN, Fuzzy and Rough Set Theory which is going to be extended to a portable Neuropathy detection system using microcontroller.
