The purpose of this study was to obtain the best anthocyanin pigment extract powder from 3 types of drying process, vacuum drying, spray drying, and  freeze-drying. The duration and temperature for each type of drying process are 15 h with temperature of 40 oC, 2 h with temperature of 120 oC (inlet) and 60 oC (outlet), 24 h with temperature of -50 o</su...

The reaction mixture of magnesium chloride with two equivalents of potassium anthranilate [K+ AnthÐ] in water gives on cooling to 0 ∞C a 60% yield of a precipitate which after drying in a vacuum has the composition [Mg(H2O)6](Anth)2 (1). Recrystallization from hot water affords an octahydrate identified as [Mg(H2O)6](Anth)2(H2O)2 (2) in a single crystal X-ray diffraction study. Contrary to find...

Developing a novel and facile way to synthesize composite aerogels plays an important role in the applications of aerogels. UV-resistant hydrophobic titania-containing silica aerogels are prepared for the first time using potassium titanate as precursor by a modified ambient pressure drying method. The well established silica-titania networks, which can be tuned from 10 to 30 nm by adjusting th...

Moon Mineralogy Mapper/Chandrayaan-1. Moon Mineralogy Mapper (M) is one of eleven instruments selected to fly onboard India’s Chandrayaan-1 spacecraft in 2008. M, selected as a NASA Discovery Mission of Opportunity in May, 2004, is a high spatial and spectral resolution spectrometer that will help scientists better understand the compositional variation of the Moon’s surface. Ms overall science...

Low-cost drying technologies suitable for rural farming areas are presented. Some of the important considerations with regard to their suitability include: 1. Low initial capital; 2. easy-to-operate with no complicated electronic/ mechanical protocol, and 3. effective in promoting better drying kinetics. The drying technologies that were selected include fluidized bed, spouted bed, infrared, so...

The Na and K concentration in single supramedullary neurons of the puffer fish (Spheroides maculatus) was measured using a dual channel integrating ultramicroflame photometer. The cells were frozen in situ, sectioned at low temperatures, and freeze-dried to prevent artefactual movements of cations. The density of the nuclear fragments was 0.15, significantly less than cytoplasm's 0.21. The sucr...

leather manufacturing involves a crucial energy-intensive drying stage in the finishing process to remove its residual moisture. determining drying characteristics of leather is vitally important so as to optimize the drying stage. this paper describes an analytical way for determination of the drying characteristics of leather. the model presented, is based on fundamental heat and mass transfe...

The effect of air temperature, air velocity, and sample shapes (circle and square with the same cross-sectional area) on kinetic drying of potato slices in a tunnel dryer was investigated experimentally and a suitable drying model was developed. The experiments of drying of potato slices were conducted at an air temperature of 45-70°C with an air velocity 1.60 and 1.81 m sec(-1). Results showed...
