Tumble dryers are widely used for drying garments, but felting shrinkage can be caused to wool garments during the tumble process. To dry fabrics or in dryers, flat function has been introduced dryers; however, energy efficiency is very low. The current study investigated fabric movement at different rotation speeds dryer and their resultant performances terms of specific moisture extraction ra...

The application of tracer techniques to the sugar industry is reviewed. This includes the investigation of residence time distribution in clarifiers, evaporators, continuous pans, crystallizers and fluidized bed dryers; the flow split in diffusers and evaporator vessels; leak detection; measurement of entrainment in vacuum pans and determination of system volumes such as cooling water ponds.

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 ...
