Carrot samples were bifacially treated with cold plasma for varying durations of 30, 60 and 90 s and dried using vacuum and convective tray dryers. Moisture ratio data were modelled using Decision Tree, Support Vector Regression, Gaussian Process Regression, Deep Feed-Forward Neural Network, and their hybrid. The HML framework demonstrated strong predictive capability across drying methods and pre-treatment conditions, maintaining consistent performance when tested on unseen data. The DOIEM approach further enhanced traditional empirical models by using a deep-learning optimizer (Adam) to improve parameter estimation and generate a two-dimensional moisture map for an offline digital twin. The resulting digital twin tracked and updated model parameters to reflect spatiotemporal changes in moisture, offering excellent prediction and interpretability. Comparatively, DOIEM provided superior modelling performance compared to the hybrid ML model in both vacuum and tray drying. The DOIEM-based twin also showed strong potential for integration into sensor-driven smart drying systems. This work establishes a practical and data-driven foundation for intelligent food drying applications and demonstrates how digital twin technologies can support real-time monitoring and control in agri-food processing.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"116 ","pages":"Article 102939"},"PeriodicalIF":2.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145880498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this way, it is necessary to determine parameters such as velocity, pressure, and temperature in order to describe the behavior of intergranular air within the grain mass. However, experimental measurement of these parameters in full-scale silos is challenging, especially when considering multiple silo geometries and different aeration duct configurations. In this context, Computational Fluid Dynamics (CFD) provides a practical tool to evaluate multiple silo and duct configurations, enabling the computational analysis of intergranular airflow through the numerical solution of the governing fluid dynamics equations. This approach allows for the assessment of airflow distribution, pressure drops, and turbulence patterns, supporting the optimization of aeration system. This study aimed to analyze air distribution in stored grains within vertical silos, considering different aeration duct geometry and configurations, as well as various grain types. The Ansys® software was used to develop the silo geometries and generate the meshes via the Workbench platform. Simulations were conducted using the CFX solver, applying the Real Velocity formulation to the governing equations for flow in porous media. The physical and operational parameters of the model were defined based on literature values, with the viscous and inertial terms determined using Ergun equation, considering air as the working fluid under steady-state conditions and boundary conditions representative of the actual aeration process. The results obtained were consistent with those reported in the literature: pressure drops varied from ∼31 kPa m⁻¹ for oats to ∼165 kPa m⁻¹ for corn, highlighting the impact of grain properties and duct design on aeration efficiency, and demonstrating the effectiveness of CFD simulation in optimizing aeration and efficiently managing grain storage.
