The main categories of in-bin dryer systems are reviewed. For Southeast Asian conditions, research on in-store dryers is discussed, as a component of a two stage drying system for maximum quality preservation and reduced drying cost. Limitations for paddy and maize exist, requiring management of the system to obtain these benefits. Examples of adoption of in-store drying in conjullction with fi...

ABSTARCT: Solar drying is an integral part of rural life for various products, especially vegetable, fruits & spices which are produced in rural areas and have no scientific means of preserving such raw products. This paper is an attempt to review the solar drying process & solar dryers used for chilli drying worldwide which includes types of solar dryer, drying process & techno economical feas...

This paper presents spatio-temporal measurements of a #uctuating pressure "eld acting on isolated roughened cylinders of "nite height in simulated turbulent boundary layer #ows at subcritical Reynolds numbers. The cylinder surface is roughened by placing discrete roughness elements along the height at four circumferential locations. The resulting surface roughness con"guration helps to modify t...

Retinal velocity distributions can lead to a percept of three-dimensional (3D) structure (structure-from-motion [SFM]). SFM stimuli are intrinsically ambiguous with regard to depth ordering. A classic example is the orthographic projection of a revolving transparent cylinder, which can be perceived as a 3D cylinder that rotates clockwise and counterclockwise alternately. Prevailing models attri...

Cyclic variability (CV) in lean HCCI combustion at the limits of operation is a known phenomenon, and this work aims at investigating the dominant effects for the cycle evolution at these conditions in a multi-cylinder engine. Experiments are performed in a four-cylinder engine at the operating limits at late phasing of lean HCCI operation with negative valve overlap (nvo). A combustion analysi...

This study was conducted with the development of instant fish soup mix and finding out the effect of fish powder on it. Ingredients of soup mix were cooked and dried up to desired moisture content. The drying or dehydration was done by using a mechanical dryer (Cabinet dryer) at constant air flow rate and constant temperature with varying thicknesses. After drying the dried products were ground...

The study is aimed at quantifying the relative contribution of key heat transfer modes in lyophilization. Measurements of vial heat transfer rates in a laboratory-scale freeze-dryer were performed using pure water, which was partially sublimed under various conditions. The separation distance between the shelf and the vial was systematically varied, and sublimation rates were determined gravime...

The ongoing changes in vegetation spring phenology in temperate/cold regions are widely attributed to temperature. However, in arid/semiarid ecosystems, the correlation between spring temperature and phenology is much less clear. We test the hypothesis that precipitation plays an important role in the temperature dependency of phenology in arid/semiarid regions. We therefore investigated the in...

Reaction conditions were evaluated for the preparation of [(6-PhTPA)Ni(PhC(O)C(OH)C(O)Ph)]ClO(4) (3) and [(6-Ph(2)TPA)Co(PhC(O)C(OH)C(O)Ph)]ClO(4) (7), two complexes of structural relevance to the enzyme/substrate (ES) adduct in Ni(II)- and Co(II)-containing forms of acireductone dioxygenase. The presence of water in reactions directed at the preparation of 3 and 7 was found to result in isomer...
