Drying is a highly energy-intensive process, accounting for 10–20%of total industrial energy use in most developed countries. The main reason for this is the need to supply the latent heat of evaporation to remove the water or other solvent. There are thus clear incentives to reduce energy use in drying: to conserve finite resources of fossil fuels, to reduce carbon footprint and combat climate...

The development of the quality control and the energy conservation needs more and more sophisticated methods in the post-harvest technologies i.e. the drying and the storage. To develop advanced methods detailed measurements are necessary to be carried out on the state of the product and the surrounding air. In this paper the development of a low range air speed sensor for this purpose is prese...

The structural and physical stability of solid dispersions have not been adequately explored during spray drying manufacturing processes. In this study a wide range of compositions of naproxen/PVP-VA 64 (poly(1-vinylpyrrolidone-co-vinyl acetate)) and miconazole/PVP-VA 64 solid dispersions prepared by different laboratory spray dryers were collected from various selected locations and used to in...

During various daily activities at home and work, hands quickly become contaminated. Some activities increase the risk of finger contamination by pathogens more than others, such as the use of toilet paper to clean up following a diarrheal episode, changing the diaper of a sick infant, blowing a nose, or touching raw food materials. Many foodborne outbreak investigation reports have identified ...

Differences in flow rates of this nature have a significant effect on the unevenness moisture content dried material, since material which remains drying chamber for an unnecessarily long time is over-dried and under-drying problem remaining dryer too short time. In article, I analyzed increasing particle-wall friction particle velocity field. The research has shown that dead zones are formed v...

This paper will highlight various methods utilized for cnvironmcntal compliance with solvent coating and laminating applications. Discussion will summarize the recovery and oxidation alternatives, including a brief overview of thc advantages and disadvantages. The paper concludes by focussing on more specific examples of solutions, including capture hooding and enclosures, dryer air flow scheme...
