Disintegration performance was measured by analysing both water ingress and tablet swelling of pure microcrystalline cellulose (MCC) in mixture with croscarmellose sodium using terahertz pulsed imaging (TPI). Tablets made from MCC porosities 10% 15% showed similar transport kinetics: within the first 15s, tablets had swollen up to 33% their original thickness fully penetrated following Darcy flow kinetics. In contrast, a porosity 5% exhibited much slower kinetics, only 17% full penetration...
Abstract There is considerable scope for the optimization of processes subject to fouling by effective management cleaning. The cleaning cycle starts with (often complex) material generated during cycle. nature deposit determines most appropriate method, which can often be optimized significantly via knowledge key mechanisms involved in removal. Links between aging and cleanability need established quantified. a wide range methods available, attention focused here on cleaning-in-place (CIP)...
This study explores the formation of circular thin-film hydraulic jumps caused by normal impact a jet on an infinite planar surface. For more than century, it has been believed that all are created due to gravity. However, we show these result from energy loss surface tension and viscous forces alone. We that, at jump, balance momentum in liquid film gravity plays no significant role. Experiments dependence orientation scaling relation balancing collapses experimental data. A theoretical...
The removal of unwanted entities or soiling material from surfaces is an essential operation in many personal, industrial, societal, and environmental applications. use liquid cleansers for cleaning decontamination ubiquitous, this review seeks to identify commonality the fluid flow phenomena involved, particularly those that determine effectiveness such operations. state quantitative understanding modeling reviewed relation topics ( a) cleanser contacting soiled area, b) processes by which...
This article reports on the use of intermittent pulsing superimposed a slow steady flow to enhance rate cleaning model food soil—namely, whey protein deposit—in well-characterized geometry. Whey deposits were generated by recirculating 3.5 wt% WPC solutions through an electrically heated annular test section and then cleaned using 0.5 NaOH, simulating industrial cleaning-in-place operations. Protein removal was monitored local measurements fouling resistance (at low heating power) total...
A major cause of refinery energy inefficiency is fouling in preheat trains. This has been a most challenging problem for decades, due to limited fundamental understanding its causes, deposition mechanisms, deposit composition, and impacts on design/operations. Current heat exchanger design methodologies mostly just allow fouling, rather than fundamentally preventing it. To address this systematic way, large-scale interdisciplinary research project, CROF (crude oil fouling), brought together...
Oral dosage forms are an integral part of modern health care and account for the majority drug delivery systems. Traditionally analysis dissolution behaviour a form is used as key parameter to assess performance product. However, understanding mechanisms disintegration critical importance improve quality The primarily impacted by hydration subsequent swelling powder compact. Here we compare liquid ingress data obtained using terahertz pulsed imaging (TPI) set mathematical models. interlink...
The shear rheology of fresh molten chocolate produced from crumb was studied over 5 decades rate using controlled stress devices. Carreau model found to be a more accurate description than the traditional Casson model, especially at rates between 0.1 and 1 s(-1). At around s(-1) (shear approximately 7 Pa) material exhibited transition solid regime, similar behavior reported by Coussot (2005) for other granular suspensions. nature suspension explored investigating effect solids concentration...
The shear and extensional behavior of two aqueous gum solutions, namely (1) 1–20 g/L guar (Torres et al., Food Hydrocolloids. 2014;40:85–95) (2) κ/ι‐hybrid carrageenan solutions (5–20 g/L), are shown to exhibit Giesekus‐fluid when in the semidilute regime. In this regime, a common set Giesekus fluid parameters described both behavior. A new analytical result describing extension filament stretching geometry is presented. This also gave reasonable predictions Trouton ratio. Higher...
