Optical Tomography: The potential of mass flow rate in rice industry

• This paper has a potential to solve the problem of online weighing in rice industry.
• This paper using a new polynomial equation to calculate the mass flow rate.
• The polynomial equation improves the previous technique that using a linear equation.

The capability of Optical Tomography (OT) to visualize pipe flow is undeniably beneficial and of utmost importance to solid gas industry. The other striking feature of OT is its ability to measure and analyze real-time mass flow rate (MFR), which enables online monitoring of material weight. This paper addresses the problem posed by online weighing system in rice industry. The current system slows down the overall industrial production by impeding the device operation, and is therefore becoming obsolete. To overcome this drawback, we confirmed that OT has great potential in online weighing process using a polynomial equation. In addition, MFR measurement can gauge weight loss of rice during the enhancement process. Encouragingly, the application of novel MFR technique to accurately monitor weight loss of rice has proven to outperform the existing system in rice industry.
