Grain drying control strategies aim for a rational energy use and a final product with low breakage levels. However, an experimental approach may be prohibitive due to the costs, scale, and theoretical complexity of this operation. The simulation environment is suitable to design equipment’s and plan operations strategies with low cost and high certainty. This work utilized system dynamics modelling to quantify the percentage of product breakage during drying in fluidized bed dryers under recirculation and tempering strategies. A sensitivity analysis of the model’s input parameters including different fractions of recirculation was performed, showing their effects on drying and post-drying product quality. Finally, we present optimizations from different objectives of drying operations. The recirculation strategy worked as an attenuator to the drying rates and combined with tempering strategy reached a minimum breakage level.

“…It is also necessary to remember that rubberised plates can be subject to wear and damage, especially when working with heavy materials, which may lead to the need for frequent replacement. In addition, the installation of rubberised plates may require additional maintenance and replacement costs, which should also be considered when choosing this method [11].…”

The purpose of the study was to identify problematic issues in the operation of bucket elevators during the loading and unloading of grain, which can lead to damage to seeds. To achieve this goal, methods of analysis and evaluation of factors that affect the damage rate of grain were used. The main results were an increase in the safety of the grain loading and unloading process using bucket elevators and a reduction in the risks of crop losses. The analysis of grain damage by a bucket elevator is of practical importance for the agricultural sector and can bring the following practical benefits: reducing the risk of product losses, as it helps to identify problem areas in the operation of the elevator and develop measures to eliminate them, improving the efficiency of work and the quality of seed grain.

“…For agriculture, post-harvest seed drying is one of the most important operations. Its basic objective is to reduce the water content of food to levels considered safe and suitable for storage (Amantea et al, 2023). The drying of agricultural commodities is a complex phenomenon, the detailed understanding of the transfer parameters (heat and mass transfer, diffusion coefficient, and thermal conductivity), as well as the kinetic behavior of drying a certain seed to be dried, is fundamental to drying performance optimization used in simulation models (Bissaro et al, 2022;Onwude et al, 2019).…”

“…The optimization of seed drying conditions is a determining and challenging task to establish the quality standard of dry products (Chen et al, 2017). The main parameters and objectives to be maximized/minimized can actively change throughout the drying process (Amantea et al, 2023). Convective drying (CD) models for seed layers consider the shape and size of individual seeds and are normally applied to describe the drying process of specific seeds (Myhan & Markowski, 2022).…”

The main objective of the present work was to assess the temperature and the initial moisture content using models of lumped and distributed parameters, in the description of the drying kinetics in the thin layer of the new Brazilian black soybean cultivar. Lumped models (Page, Newton, Approximation of Diffusion, Hii, Law and Cloke, and Midilli) were fitted based on experimental moisture content data for drying experiments carried out in different temperatures. Fractional order model was also performed and it was generalized as a function of temperature. Distributed parameter models were also fitted to evaluate the influence of initial moisture content on drying kinetics, in addition to estimating the moisture profile along the position inside the black soybean seed. Results indicated that the best kinetic fitting of drying by the lumped parameter technique was obtained for models with a greater number of parameters.Practical applicationsResults indicated that the best kinetic fitting of drying by the lumped parameter technique was obtained for models with a greater number of parameters. The generalized model showed with first degree function, and the maximum global deviation was 15%, and distributed parameters were predicted with a maximum overall deviation of 10%. This result portrays that the fractional order model can be applied to describe the continuous drying process.
