Drying methods for protein pharmaceuticals
Drug Discovery Today: Technologies, 2008Removal of water is a common method to prolong the storage stability of protein formulations. Traditionally, freeze-drying has been the method of choice, but spray drying and supercritical drying have gained increased interest in the past decade. The proper choice of drying technology has a significant impact on the final pharmaceutical product and on ...

Modern Modelling Methods in Drying
Transport in Porous Media, 2006Several modern modelling techniques are presented as tools for drying science and technology, namely pore networks, discrete element method and population balances. After first presenting results from their own research, the authors indicate what future contributions to a better understanding of the drying process at different levels—single porous ...

Modern Methods of Drying Nanomaterials
Transport in Porous Media, 2006This paper presents the types of nanomaterials whose technology requires drying during processing. The methods of drying of three groups of nanomaterials are discussed: nanoparticles, nanolayers (nanofilms), and nanoporous materials. Principally the method of spray drying using ultrasonic nebulizers and electrospraying is presented for the first group.

This paper presents the results of investigations of the moisture and temperature distribution in drying by the conduction method, by means of a radio-frequency electromagnetic field, and by the combined method of heating at a low pressure. The rate of drying by the combined heating method is twice higher than in conduction heating and 1.5 times higher

Abstract Dry methods offer several advantages including low financial and environmental impacts. However, the relatively large particle size distribution combined with difficulty in surface functionalization reduces the scope of their applications. The majority of dry methods are based on mechanical and gas-phase processes. Other techniques including

Water is the most dangerous factor for buildings. Each penetration into the building structures results in a number of problems, from technical and economic to health-related ones. Issues related to the drying of buildings are very complicated. This is mainly due to the way in which different construction and finishing materials react to water and ...

The majority of lumber-drying kilns are worked at atmospheric pressure and are direct-fired or steam-heated, sometimes using wastewood as the primary fuel. However, other heating arrangements have been advocated, including the use of solar, microwave and radiofrequency energy, or of superheated steam, besides the possibility of working under vacuum to ...

Machinery and methods in freeze-drying
Cryobiology, 1971Abstract The author assumes familiarity with literature on the freeze-drying of biologicals to which he provides a critical supplement. Freeze-drying should be conceived as part of a total system and in terms of the end product. This product is not an end in itself, and must satisfy clinical and commercial requirements which can be optimized, if at ...
