Feasibility Study for Applying Desiccant to Low Temperature Vacuum Drying Process

Low temperature vacuum drying – gentle on bacteria and the environment

Lyophilizing Foot-and Mouth Disease Virus at Low Drying Temperature

Low temperature vacuum drying: evaluation of excipients in injectable dosage forms.

Low temperature vacuum drying is an alternative to sterile dry filling as a formulation approach for certain ethanol soluble substances that are poorly soluble or unstable in aqueous media. To date this ap­ proach has been limited to formulations containing the drug per se. However, several substances appear suitable as excipients in­ cluding urea, polyethylene glycol 4000, ascorbic acid, methy...

Temperature Control in the Technology Process Drying

There is described a control system for the new technology in this paper. That technology, makes it possible to process chromium tannery wastes with the help of enzymatic hydrolysis and was created at the Department of Automatic Control Faculty of Technology UTB in Zlín. The enzymatic hydrolysis process is composed from three parts: fermentation, filtration and drying. In this paper there are d...

Nonequilibrium Thermal Dynamic Modeling of Porous Medium Vacuum Drying Process

Porous medium vacuum drying is a complicated heat and mass transfer process. Based on the theory of heat and mass transfer, a coupled model for the porous medium vacuum drying process is constructed. The model is implemented and solved using COMSOL software. The water evaporation rate is determined using a nonequilibrium method with the rate constant parameter Kr. Kr values of 1, 10, 1000, and ...
