摘要: Abstract Effects of deviations in airflow properties and product on cooling chicory roots were studied based numerical simulations with a validated transient model coupled heat mass transfer bulks roots. The was solved for one-dimension 1-m deep bulk cooled at various levels air velocity, temperature relative humidity. Variations porosity, respiration capacity as well. results led to an improved understanding the process respect control strategies cold store practice. smallest sensitivity conditions found low velocity (0.1 m s−1), (1 °C) high RH (95%). Small these could, however, still lead increased weight losses by much 4% after 3 months storage. porosity rates significantly affected loss variations.
