Automatic Color Mixing Plant
Colors plays an important role in our regular lives. There are multiple shades of a single color which varies their
basic concentration. The mixing process of liquid is the most significant and demanded process in any industry. The main
objective of industries is to improve the efficiency, increase the productivity rate, reduce errors and eliminate human efforts.
In past, industries used to change the combination of color by changing their concentration manually. Minor adjustment in
color combination can change the entire shades of color which causes complications in an industrial sectors. To overcome
this problem, we have designed a prototype that will automate the mixing process. In this technologically advanced era,
technology is playing a vital role in the development of various industries in which there is no need of human assistance to
perform any task. Various type of mixing can be done, it can be either color mixing or any other liquid mixing. Color
mixing is the process of developing new colors by using the combination of primary colors. It is either done manually or
performed on machine with a lot of human effort. We have initiated a programmable logic control PLC based system that
gives the desire color by mixing the primary colors with their specific ratios. A user friendly HMI has been designed to make
the system more convenient and can be easily operated by a non-technical person. Availability of input colors are mentioned
in our system. User can create any color combination with his own ratio of the three basic colors that need to be selected on
HMI or user can select pre-defined output colors. To achieve the required concentration, our system is comprised in close
loop that monitor the flow of basic color and the output is verified by industrial color detector sensor. This system can be
implemented in many industries such as food industries, textile industries and paint industries etc. This process has vast
applications in different areas of industrial sectors.
