Ultrafine powder of roasted red ginseng was produced, using a low temperature turbo mill, and then the particle size distribution, water solubility index and Rg3 content of coarse and ultrafine powder was investigated. The mean particle size of ultrafine powder is abruptly decreased from < 1250 µm into about 30 µm, and there is more than 20 times reduction in particle size, compared to that...
We propose a novel digital on-channel repeater (DOCR) for T-DMB system where DOCR is equipped with multiple receive antennas. Prior works have focused on the DOCR with a single antenna so that the equalized DOCR (E-DOCR) combined with time-domain zero-forcing equalizer and feedback interference canceller is the latest structure. In this paper, the new paradigm structure is proposed by introducing...
BACKGROUND: The characteristic of whole soybean curd is that it includes the soybean residue that is discarded as waste in the manufacture of usual soybean curd (known as tofu). In this study the effect of dietary whole soybean curd on lipid profiles in rats was compared with that of usual soybean curd. Rats were fed for 4 weeks with diets differing only in the source of protein, namely casein, whole...
This study was performed to compare antioxidant activity of natural formulated functional food (NFFF). Ultrafine powder of NFFF that d(0.9) is 1.645 µm and difference of particle size between d(0.1) and d(0.9) is about 1.066 µm was produced, using a low temperature turbo mill. As the result to feed ultrafine powder to the mice, the antioxidant activity was significantly increased in U + CCl4 group,...
This study was done to develop a pilot equipment, which can pulverize and classify ginseng into 3 μm size of powder, and in which R-22 cooling system is installed to preserve pharmacological compounds and make plant materials brittle. Pulverizing mechanism, in which rotor and stator can destroy the cell wall of plant materials effectively by high shear, and classification mechanism, which uses centrifugal...
