Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

Chemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.

Modeling Steam Dryers

, 2010
Nuclear steam dryers are used to reduce the moisture carryover (MCO) to levels often well below 0.1%, by weight, water in the steam. The dryers are designed to provide very high quality steam at the full capacity of the steam generator.

Thermodynamic Analysis of Superheated Steam and Flue Gas as Drying Agents for Biomass Dryers

Chemical Engineering Transactions, 2020
Bagasse is a sugarcane byproduct of high moisture content that usually requires drying before its use in the production of heat, power, fuels, and chemicals. This work explores the possibility of replacing flue gas, a hazardous heat source, with steam in

Perceptions of Governance (Il)Legitimacy Mediate Climate Change Adaptation in the Lake Victoria Basin, Uganda

Environmental Policy and Governance, EarlyView.
ABSTRACT Governance is a well‐known dimension of adaptive capacity across various frameworks, however specific links between perceptions of governance (il)legitimacy and adaptive capacity remain relatively unexplored. In this study, we investigate connections between climate change adaptation and perceptions of governance (il)legitimacy using focus ...

Hydrogen Production With Water Electrolysis Technologies: Advances, Performance, and Potential Use for Low‐Gradient Combustion

Energy Science &Engineering, EarlyView.
This review links recent advances in water electrolysis with hydrogen utilization in low‐gradient combustion systems. While hydrogen eliminates direct CO2 emissions, its environmental and economic benefits depend strongly on production pathways, system‐level efficiency, and NOx mitigation through MILD/FLOX/HiTAC combustion.

Neurolathyrism in Sub‐Saharan Africa—Assessing the Neurotoxic Risks of Lathyrus sativus Amid Drought and Food Security Challenges

Food Safety and Health, EarlyView.
Representation of grass pea consumption in drought‐stricken sub‐Saharan Africa sustains nutrition, but excess β‐ODAP exposure due to multiple reasons triggers neurolathyrism, a progressive neurotoxic disorder. ABSTRACT Neurolathyrism is a progressive motor neuron disease due to the consumption of Lathyrus sativus (grass pea) over long periods.
