Summary

The Food Process Robot Intelligent System (FPRIS) uses AI and computer vision for automated coffee roasting. This intelligent system precisely controls roasting degree, enhancing efficiency and quality.

Area Of Science

Robotics and Automation
Artificial Intelligence
Food Science

Background

Traditional coffee roasting lacks precise control over the degree of roasting.
Automation in food processing can enhance efficiency and product consistency.

Purpose Of The Study

To develop and evaluate the Food Process Robot Intelligent System (FPRIS) for automated coffee roasting.
To investigate the system's ability to control the Degree of Roasting (DoR) using integrated sensors and AI.

Main Methods

Integration of a 3D-printed six-axis robotic arm with AI and Computer Vision (CV).
Utilizing a Convolutional Neural Network (CNN) for real-time coffee bean classification and roaster control.
Combining gas and image sensor data for assessing coffee bean quality and DoR.

Main Results

FPRIS demonstrated precise control over the DoR by correlating sensor data with roast intensity.
Consistent trends observed: increased weight loss and Gas sensor Initial Difference (GID), decreased Sum of Pixel Grayscale Values (SPGVs) with higher roast intensity.
The system effectively navigated obstacles and empty spaces within the roaster.

Conclusions

FPRIS offers enhanced precision and efficiency in automated coffee roasting.
The system shows potential for broader applications in food processing automation.
Further research can establish FPRIS as a universal automation solution for the food industry.
