Numerical Evaluation of Residual Water Content after Freezing during the Lyophilization of Platelets

The air permeability coefficient has a high correlation with the water content of municipal solid waste. In this study, continuous drying methodology using a tension meter was employed to construct the soil water characteristic curve of municipal solid waste (M-SWCC). The municipal solid waste air permeability test was conducted by a newly designed apparatus. The measured M-SWCC was well reproduced by the van Genuchten (V-G) model and was used to predict the parameters of typical points in M-SWCC, including saturated water content, field capacity, residual water content and water content at the inflection point. It was found that the M-SWCC was significantly influenced by void ratio. The final evaporation and test period of M-SWCC increase with the increase in void ratio of municipal solid waste. The evolution of air permeability coefficient with water content of municipal solid waste depicted three distinct characteristic stages. It was observed that the water contents that corresponded to the two cut-off points of the three stages were residual water content and water content at the inflection point, respectively. The air permeability coefficient of municipal solid waste decreased with the increase of the water content from zero to the residual water content. The air permeability coefficient was almost invariable when the water content increased from residual water content to the water content at the inflection point. When the water content of municipal solid waste exceeded the water content at the inflection point, the air permeability coefficient sharply decreased with the increase of water content.

The Right

In the light of the constantly growing requirements regarding efficiency, work safety and increasing capacities the design of silos and its conditioning systems demands for customer-specific and experience-based approach. After production fresh sugar has a residual water content which can lead to agglomerations during storage. This affects the product quality, discharge and transport from the silo and endangers staff who has to remove cakings manually. Therefore it is necessary to prepare and distribute the air constantly at optimal conditions. Time of conditioning, air quantity and humidity are the parameters to be determined simultaneously based on the type of silo, residual water content of stored sugar, size of sugar crystals, product feed-in rate and environmental conditions [1]. In the design the amount of water to be removed, air distribution in the sugar bed and temperature are considered. Depending on weather conditions the supplied air is mixed with fresh, dried, cooled or heated air to meet the needed conditions and to enable an energy-efficient operation of the plant.
