Magnetic resonance imaging (MRI) and other techniques are being used to investigate moisture transport in textiles. MRI revealed that moisture distribution in carpet is significantly influenced by the details of the vacuum extraction procedure used to remove excess water. Industrially relevant through-flow drying of carpet has been simulated on a laboratory-scale dryer as well as inside an MRI ...

In 1890 Alt man dried pieces of frozen tissue by placing ¡hem in a vacuum desiccator at —20 °C. Since then the freeze drying technique has been constantly improved. In ¡939 the freeze drying process was placed for the first time on an engineering basis, and 1940 saw the large-scale production of dried plasma for wartime use. The first book unfreeze drying by Flosdorfin 1949 was followed by the ...

The production of vacuum dried egg powder through a simplified technique was studied. The advantage of egg powder with its production and variation in its technology which helps for a better quality and cost efficient product was tested. Eggs as a raw source were collected from the local poultry farm and processes for production were carried out. High risk factors like, reduced glucose in the d...

We describe the design, construction, and operation of a simple glow discharge unit that can be used to make surfaces such as carbon-coated electron microscopy grids and glass coverslips hydrophilic. The use of a vacuum leak detector (Tesla coil) in place of a conventional high-voltage power supply and a small plastic desiccator for the vacuum chamber make the unit very inexpensive. Owing to th...

As one of the most common solid wastes, municipal sewage sludge needs to be dried before its disposal and resource reuse. In this study, effects vacuum degree, heat source temperature thickness on drying rate odor concentration in tail gas were studied through orthogonal experiments carried out lab-scale heat-conductive device; The comparative atmospheric state (-0.08MPa). results show that is ...

Abstract Kuini powders were obtained through spray-drying, freeze-drying, vacuum oven drying and convection drying. Colour, water activity (Aw), moisture content, hygroscopicity, wettability, flowability, degree of caking, solubility index (WSI), total colour change, phenolic content carotenoid determined compared. Convection resulted in the highest yield (46.97%), (4.91%), Aw (0.55) WSI (74.33...

Drying is one of the oldest methods for food preservation that removes water from fruit and makes it available consumption throughout year. Dried fruits can be produced by small- large-scale processors, which them a very popular among consumers manufacturers. The most frequent uses drying technology include osmotic dehydration, vacuum drying, freeze-drying different combinations other technolog...
