?

Abstract

?

Cocoa bean drying is a crucial step in chocolate production, as the moisture content of the beans directly influences the quality of the final product. In this study, we present a modeling approach based on irreversible thermodynamics concepts to simulate the drying process of cocoa beans. The model takes into account the heat and mass transfer mechanisms that occur during drying, as well as the effects of temperature and humidity on the drying kinetics.

?

To validate the model, experiments were conducted using a laboratory-scale drying chamber with controlled temperature and humidity conditions. Cocoa beans were subjected to different drying conditions, and the moisture content of the beans was measured at regular intervals. The experimental data was then compared to the simulation results obtained from the model.

?

The results showed good agreement between the experimental data and the simulation predictions, indicating that the model accurately captures the drying behavior of cocoa beans. The model was able to predict the drying kinetics of cocoa beans under different conditions, including variations in temperature and humidity.

?

Furthermore, the model was used to analyze the energy consumption during the drying process and to optimize the drying conditions to improve energy efficiency. The simulation results showed that by adjusting the temperature and humidity settings, it is possible to reduce energy consumption and shorten the drying time without compromising the quality of the dried cocoa beans.

?

Overall, this study demonstrates the utility of irreversible thermodynamics concepts for modeling and simulating the drying of cocoa beans. By understanding the fundamental principles governing the drying process, it is possible to optimize the drying conditions, improve energy efficiency, and ensure the quality of the final product. This research has important implications for the chocolate industry, as it provides a valuable tool for improving the efficiency and sustainability of cocoa bean drying processes.
