This paper describes the development of a new finger-ring shaped sensor device with a coil of wire for recognizing the use of handheld electrical devices such as digital cameras, cellphones, electric toothbrushes, and hair dryers by sensing time-varying magnetic fields emitted by the devices. Recently, sensing the usage of home electrical devices has emerged as a promising area for activity rec...

The advantage of using paddle dryers (PD) in the production of sugars and 2nd generation ethanol from pretreated wheat straw was investigated. This machinery was employed in order to detoxify steam-exploded substrates and to mix different slurries in the hydrolysis step. The obtained hydrolysate was fermented by the yeast Saccharomyces cerevisiae. Acetic acid and furfural were reduced up to 11 ...

The use of compatible techniques, which allow family coffee growers to form larger batches coffee, be dried in commercial dryers and within their production reality, is very important view the scarcity labor demand for superior quality. As natural drying, depending on climatic conditions, may not produce high quality coffees, it necessary that farmer maintain small daily harvests conditions can...

Energy consumption, environmental issues, product quality are actual problems related to grain drying processes. It is necessary pay attention designing new structures of energy-efficient dryers. A structure an dryer based on thermosiphons has been designed; its energy consumption 3.5...6.8 MJ/kg depending surface temperature and air flow rate. The includes a layer heater, chamber, heat generat...

An experimental methodology was developed to improve the energy design of paddle dryers for sewage sludges. A laboratory batch dryer with a vertical agitator has been especially designed and instrumented to determine the heat flux densities. To determine the drying kinetic and the evaporating flow rates, the specific heat and the total heat of desorption of the sludge were measured using calori...

The influence of granulometric properties of the material and of the operational conditions on the drying kinetics of nonhygroscopic material was studied. Four fraction sizes of dolomite were chosen and dried in four dryers by different heating methods. Dolomite was dried in a microwave dryer under different microwave heating powers. During convective drying the effects of temperature and super...

Purpose To focus on challenges & strategic approaches in implementing „Management Information System (MIS)‟ for process equipment (For Ex: Pressure Vessels, Boilers, Heat Exchangers, Agitators, Dryers, Storage Containers) manufacturing industry. Approach Case study Findings There was about 20% of productivity improvement after successful implementation of MIS for various divisions in the organi...
