−− The results obtained in the analysis of the thermal behaviour of a forest biomass fluidized bed dryer with mechanical agitation, are reported. The study is carried out in a pilot size experimental equipment in batch operation. By means of Taguchi’s techniques the specific consumption of energy and the rates of evaporation of water and production of dry biomass are analyzed based on the contr...

In a study using a heated chamber for induction of experimental febrile seizures (eFS) in rat pups, ictal activity was shown to be precipitated by a respiratory alkalosis (Schuchmann et al., 2006). In sharp contrast to this, in a recent review Dubé et al., (2007) suggest that the respiratory alkalosis is model specific, and that no increase in respiratory rate is observed in the widely used "ha...

in this project, first we introduced a general rule for the design of drying processes and then, we have applied microsoft excel for this purpose. belt dryer is one of the most common dryers in the food industry. in this study, our aim was to process carrot by this dryer. we optimized the target function (total annual cost or tac) and investigated the influence of design variables on this targe...

In Central Europe approximately 30% of the grain must be dried after harvest. The most popular continuous crop dryers are mixed-flow dryers. Although this type of dryer is widely used it is still necessary to optimize many segment processes during the drying. For example there are big differences in the vertical grain particle velocity causing differences in the residence time. The aim of the w...

Spray drying is a commonly used method of drying a liquid feed through a hot gas. This study aims to obtain the empirical model of the spray drying process of full cream milk using a nozzle atomizer spray dryer, Lab-Plant SD 05 Laboratory Scale Spray Dryer. Inlet air temperature was chosen as the manipulated variable and outlet air temperature was the controlled variable. No disturbance was con...

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...

The physiological properties of clothing designed to provide protection against cold, windy and damp conditions affect comfort. The weight, thickness, stiffness of the fabrics and friction between the clothing layers affect physical performance. The comfort and perception of performance associated with 3 military winter combat clothing systems from different decades (the new M05 system, the pre...

Davis, Gillon and Matthewson (hereafter Davis et al) argue that “hypothesisdriven fieldwork has led to a more complete and accurate picture of linguistic diversity than has been produced by methods which rely largely on extracting information from existing descriptive grammars”. They discuss five cases to support their conclusion. In this response, I will discuss only one of these cases, since ...

drying is a high energy consuming process. solar drying is one of the most popular methods for dehydration of agricultural products. in the present study, the performance of a forced convection solar dryer equipped with recycling air system and desiccant chamber was investigated. the solar dryer is comprised of solar collector, drying chamber, silica jell desiccant chamber, air ducts, fan and m...

this study determined optimum conditions for drying pomegranate arils in a solar dryer. a cabinet solar dryer was used in active and mixed modes. the response surface method was employed with nine treatments (runs) and a control run (3 m/s air velocity and 2 cm in thickness) and five replications. the bryte cultivar was tested and samples were dried to approximately 10% moisture. drying time, v...
