Objective
Society for Applied Microwave Electronics Engineering & Research - (SAMEER
hereinafter referred as ‘Authority’) invites applications for “Expression of Interest for the
Technology of Microwave Based Compact Cost Effective Brix Meter for Sugar Industry” from
reputed organization/public sector units with relevant experience.
1. INTRODUCTION
Society for Applied Microwave Electronics Engineering and Research (SAMEER) is an
autonomous R & D institution under the Ministry of Electronics and Information Technology
(MEITY), Government of India. SAMEER pursues application-oriented research and
development activities in the areas of Medical Electronics, RF and Microwave systems,
Photonics, EMI/EMC Engineering, Antenna, and Electromagnetic, Communications, Thermal
Engineering, radar- based Atmospheric Instrumentation, and related software. SAMEER with a
focus on application- oriented R & D, undertakes projects, customized product development,
and design consultancy in these specialized areas.
SAMEER has successfully completed and demonstrated the Proof of Concept for “Design and
Development of a Compact Cost effective Brix Meter for sugar industry”. In continuation with
the same, MeitY sponsored the project “Design and Development of a Microwave Based
Compact Cost effective Brix meter for Sugar Industry” for production of a cost-effective and
maintenance free sensor for the measurement of Brix in syrup during the sugar boiling process
in the sugar industry. This project was aimed at designing and developing a compact and cost
effective microwave based Brix meter for the sugar industry.
Under the project, SAMEER has developed cost effective Brix meter. The Technological
outcomes of this project are:
● A compact, mechanically suitable and sustainable microwave based Brix measurement
Insertion probe for vacuum sugar boiling pan
● A compact microwave trans-receiver system for Brix measurement of sugar syrup with
data processing and data logging system.
In sugar plants, the quality of sugar as determined by International Council for Unified Methods
of Sugar Analysis (ICUMSA) greatly depends on the degree of super saturation of syrup when
seeding is attempted. Seeding has to be carried out within a narrow band of syrup super
saturation. Concentration of sucrose in sugar solution is expressed in ºBrix. If it is too low, the
crystallization rate suffers and above the maximum limit, spontaneous nucleation takes place,
both of which results in poor quality and low recovery of sugar from syrup. Hence it is most
desirable to know the syrup concentration at all times during the sugar boiling process so that its
super saturation may be held within certain limit
Several measuring techniques have been used in the past for judging the syrup oversaturation.

One, still widely used, is the electrical conductivity of boiling syrups and massecuites. This will
give a rough but not specific estimation, since conductivity is affected by crystal crop, soluble
electrolyte content of the syrup etc. Another method which has been greatly accepted uses the
Refractive index of boiling syrups. Though reliable results were obtained with this method, it
presents mechanical maintenance difficulties and is a slow measurement process due to the time
required to change the viscous syrup film adjacent to measuring prisms.
However, the technology developed by SAMEER is microwave based technology which gives
reliable results and can be deployed online in-situ condition. Brix measurement by this method
is reasonably good as concluded in the earlier Proof of Concept (POC) level project in
comparison to Boiling Point Elevation (BPE) and other methods as described above
