An intermittent noise that occurs around 30 seconds after compressor start-up has been disturbing customers of many domestic refrigerator manufacturers over the past 10 years. This noise is very similar to that produced by popcorn popping, being referred to as popping noise. The most probable cause of this strange and unpleasant noise is thought to be CIS (Condensation Induced Shock). The aim o...

AIMS To compare an ultra-rapid hand dryer against warm air dryers, with regard to: (A) bacterial transfer after drying and (B) the impact on bacterial numbers of rubbing hands during dryer use. METHODS AND RESULTS The Airblade™ dryer (Dyson Ltd) uses two air 'knives' to strip water from still hands, whereas conventional dryers use warm air to evaporate moisture whilst hands are rubbed togethe...

Abstract—Present study focused on the utilization of solar energy by the help of photovoltaic greenhouse solar dryer under forced mode. A single slope photovoltaic greenhouse solar dryer has been proposed and thermal modelling has been developed. Various parameters have been calculated by thermal modelling such as greenhouse room temperature, cell temperature, crop temperature and air temperatu...

The Nano Spray Dryer B-90 offers a new, simple, and alternative approach for the production of drug nanocrystals. Among attractive drugs, calpain inhibitor that inhibits programmed cell death 'apoptosis' is a candidate for curing apoptosis-mediated intractable diseases such as Alzheimer's disease and Parkinson's disease. In this study, the preparation of calpain inhibitor nanocrystals using Nan...

Better understanding (and so better control) of the stickiness phenomenon of drying sludge is critical for proper operation of a variety of industrial dryers, as is the case for the combined centrifuge-dryer system used on the Monsanto Europe site in Antwerp, Belgium. In this paper a binary logistic regression analysis is performed on a 4-years data base, which resulted in an empirical model fo...

Developing a sustainable photovoltaic-thermal (PVT) solar drying system is essential to maintain zero carbon emission in the process. This work represents of star fruit novel PVT dryer analyze sustainability indicators based on energy and exergy performance with environmental economic evaluation (4E) under forced convection (FCD) natural (NCD). The moisture content decreased from 10.11 (d b) 0....

Introduction The stability of the paper machine short circulation, forming and press section are tightly connected. A new online measurement, IQInsight, now provides true instantaneous MD and CD profiles from the press section. This unique measurement device provides new possibilities for stabilizing and optimizing paper machines. The accurate and continuous moisture profile just after the pres...

Spray dryers are widely used in the chemical, pharmaceutical and food industries to turn liquid products into free flowing powder. To increase the energy efficiency and improve the product quality, the dryer in question combines drying in four stages, instead of single stage drying. In this paper, we present our latest developments within advanced process control for the four-stage spray dryer....

Dryer system is a controlled plant which is normally used in chemical industry. The proper modeling of this system facilitates its maintenance and keeping. Normally this is not an easy task, unless having a complete model of the process, due to sudden and nonlinear events. In this paper the linear identification of dryer plant in Arak petroleum, is introduced according to the Autoregressive wit...
