This study introduces an AI-powered computer vision system for real-time coffee bean classification during roasting. The Coffee Bean Classification Model (CBCM) accurately identifies beans, optimizing quality control in complex food processing environments.
Area of Science:
- Food Science and Technology
- Artificial Intelligence in Manufacturing
- Computer Vision Applications
Background:
- Modern food processing demands advanced quality control methods.
- Integrating artificial intelligence (AI) and computer vision offers solutions for complex processing environments.
- Real-time monitoring is crucial for optimizing food production.
Purpose of the Study:
- To develop and evaluate an AI-based computer vision system for coffee bean classification during roasting.
- To assess the performance of a Machine Learning (ML) model in identifying coffee beans amidst obstacles.
- To enable quantitative analysis of coffee bean color changes during the roasting process.
Main Methods:
- Development of a Coffee Bean Classification Model (CBCM) using Machine Learning (ML).
- Implementation of a computer vision system integrated with Deep Learning (DL) technology.
- Testing the model's accuracy and loss in a simulated rotating roasting machine environment.
Main Results:
- The CBCM achieved a maximum validation accuracy of 98.44% and minimum validation loss of 5.40%.
- On a test dataset, the CBCM demonstrated high accuracy (99.27%) and low loss (2.82%).
- The system successfully quantified color variations in coffee beans during roasting, even with obstacles present.
Conclusions:
- The developed AI-driven computer vision solution effectively classifies coffee beans in complex roasting environments.
- The CBCM shows high accuracy and reliability for quality control in coffee processing.
- This technology enables precise monitoring and optimization of the coffee roasting process.
