“…These parameters were not obtained as function of grain layer height, therefore, a direct comparison cannot be possible; but there is an intersection for the parameter D in both studies, whereas the range of the parameter F in Liu et al ( 2022) is smaller and outside the range of these results. One possible explanation is the difference in soybean grains: the equivalent particle diameter used by Liu et al (2022) to represent the soybean as a sphere was 7.24 mm, whereas in Brazil, a typical equivalent diameter would range from 5.40 to 6.40 mm (Lorenzoni et al, 2020).…”

“…One of the main processes used to maintain grain quality in large storage bins is aeration. Aeration systems are very important in hot climates (Lopes & Steidle Neto, 2019;Panigrahi et al, 2019), where chilled aeration systems can be used (Morales-Quiros et al, 2019). Aeration systems can also be used do dry grains during storage (Coradi & Lemes, 2018).…”

One of the main processes used to maintain grain quality in large storage bins is aeration. An optimization model that considers the limited and discrete nature of the air inlets, in addition to the geometric characteristics of the storage bin, could produce results more easily applicable results for the design of new grain storage bins. The objective of this study was to parameterize and to apply the Darcy-Forchheimer model for simulating airflow in soybean grain mass as function of grain layer height, and develop an artificial intelligence method based on genetic algorithm for optimizing grain storage bin dimensions and air inlet configurations to obtain a more homogeneous airflow in the grain mass. The parameterization considered the effect of grain compaction and the OpenFOAM simulations showed good agreement with the experimental data. The proposed genetic algorithm was able to increase the airflow homogenization when compared to the grain storage bin used as reference.

“…Drying under traditional dryers' configurations such as counterflow dryers [2] , mixed-flow dryers [3] , fixed-bed dryers [4] may expose the product into undesirable drying conditions that may result in thermal/mechanical damage and lower germination rates [5] . As an alternative to conventional dryers, the development of new dryers and new strategies have been developed aiming improve thermodynamic efficiency and product quality after drying [6,7] .…”

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.
