This paper presents a novel approach to thermal process control in the food industry, specifically targeting the pasteurization and cooking of soft-boiled eggs. The unique challenge of this process lies in the precise temperature control required, as pasteurization and cooking must occur within a narrow temperature range. Traditional control methods, such as fuzzy logic controllers, have proven insufficient due to their limitations in handling varying loads and environmental conditions. To address these challenges, we propose the integration of robust reinforcement learning (RL) techniques, particularly the utilization of the Deep Q-Network (DQN) algorithm. Our approach involves training an RL agent in a simulated environment to manage the thermal process with high accuracy. The RL-based system adapts to different heat capacities, initial conditions, and environmental variations, demonstrating superior performance over traditional methods. Experimental results indicate that the RL-based controller significantly improves temperature regulation accuracy, ensuring consistent pasteurization and cooking quality. This study opens new avenues for the application of artificial intelligence in industrial food processing, highlighting the potential for RL algorithms to enhance process control and efficiency.
本文提出了一种食品工业中热加工过程控制的新方法,特别针对溏心蛋的巴氏杀菌和烹饪。该过程的独特挑战在于所需的精确温度控制,因为巴氏杀菌和烹饪必须在狭窄的温度范围内进行。传统的控制方法,如模糊逻辑控制器,由于在处理变化的负载和环境条件方面存在局限性,已被证明是不够的。为了应对这些挑战,我们建议集成强大的强化学习(RL)技术,特别是深度Q网络(DQN)算法的应用。我们的方法包括在模拟环境中训练一个RL智能体,以高精度管理热加工过程。基于RL的系统能够适应不同的热容量、初始条件和环境变化,表现出优于传统方法的性能。实验结果表明,基于RL的控制器显著提高了温度调节精度,确保了一致的巴氏杀菌和烹饪质量。本研究为人工智能在工业食品加工中的应用开辟了新途径,突出了RL算法在提高过程控制和效率方面的潜力。
