Mist sauna is a style of bathing in which hot water vapor is sprayed into a bathroom, establishing an air temperature of 40°C with saturated humidity. Bath heater and dryer equipment with mist sauna function was released onto the Japanese market in 2004. After their introduction, various studies investigated the effects of mist sauna bathing, and it has been demonstrated that mist sauna bathing...

common drying systems, including hot air convection, infrared, vacuum and ir-convective were employed to investigate and analyze the drying process of mulberry fruits. to evaluate the effect of pretreatment on the drying phenomenon, samples were pretreated by being subjected to: microwaves, chemical preparation, mechanical as well as blanching approaches. results revealed that the microwave pre...

The structural parameters of a grain dryer are directly related to the its energy consumption and quality formation. Therefore, based on Ergun model, air state uniformity evaluation method, effect changes in ventilation area airflow resistance, drying consumption, efficiency theoretically experimentally studied this work under same initial weight flux. results show that conditions temperatures ...

Global waste production has raised recently due to numerous agricultural and industrial activities. Among other actions devoted to waste reduction, revaluation seems to be the most advantageous one from an environmental and economic point of view. In the olive oil sector, by-product management (namely olive pomace, olive mill wastewater, and sludge residue) poses serious problems for companies,...

BACKGROUND An outbreak of Stenotrophomonas maltophilia was observed in the cultures of bronchial aspirations. After systematic culturing of the scopes and reprocessing the equipment, it turned out to be a pseudo-outbreak caused by a failure of the disinfector to sterilize ultrasound scopes, subsequently resulting in cross infection of the bronchoscopes via the connecting tubes in the dryer. O...

A cold plasma ionization device has been designed to monitor freeze-drying processes in situ by monitoring lyophilization chamber moisture content. This plasma device, which consists of a probe that can be mounted directly on the lyophilization chamber, depends upon the ionization of nitrogen and water molecules using a radiofrequency generator and spectrometric signal collection. The study per...

The purpose of this article was to present a new drying method for agricultural products. Electrohydrodynamic (EHD) has been applied for drying of agricultural materials due to several advantages such as energy saving, low cost equipment, low drying temperatures, and superior material quality. To evaluate this method, an EHD dryer based on solar (photovoltaic) energy was designed and fabricated...

An experimental investigation was conducted to study the performance of a novel indirect type free convection solar dryer. The and conventional passive dryer were built. Solar irradiation temperature different locations recorded. air at drying chamber entrance, lower space, upper space temperatures besides thermal efficiency 68, 39, 49 85%, respectively, higher than one.

rotary atomizers are commonly used in spray dryers to atomize feed. one destructive effect of wheel rotation is the creation of a vacuum inside the wheel that conducts hot air from the chamber into the wheel and can lead to atomizer blockage and an explosion. the present work determined the air-pumping characteristics of a rotary atomizer with a 50 mm wheel diameter. the vacuum pressure and pow...
