20090072798 | APPARATUS AND METHOD FOR APPLYING HIGH VOLTAGE WITH HIGH FREQUENCY - An apparatus and a method for applying high voltage with high frequency. The apparatus includes a power generator for generating electric power with predetermined frequency, a voltage transformer receiving the electric power generated by the power generator, amplifying voltage of the electric power received, and applying the amplified voltage to a load, and an impedance matcher connected between the power generator and the voltage transformer to match impedances of the power generator and the voltage transformer to thereby transmit the electric power to the voltage transformer. High voltage with high frequency is obtained by transmitting the electric power generated from the power generator to the load without reflecting loss while conducting an impedance matching, and amplifying the voltage applied to the load using the coupled inductor and LC resonance. | 03-19-2009 |
20090093037 | METHOD AND APPARATUS FOR ACCELERATING GROWTH OF LACTIC ACID BACTERIA WITH ELECTRIC FIELD - The method and apparatus for accelerating growth of lactic acid bacteria, which apply an electric field to the lactic acid bacteria using an electric field in a frequency band of 1 kHz to 1 MHz, can be applied to all lactic acid bacteria used in home and industries to accelerate the growth of them and can be used to increase the number of the lactic acid bacteria and the production of all metabolites (for example, lactic acid and carbon dioxide) of the lactic acid bacteria. The invention increases the lactic acid bacteria and the production of the metabolites of the lactic acid bacteria, thereby activating the beneficial fermentation action of the processed foods such as fermented milk, lactic acid bacteria-containing beverage, toenjang or salted foods (kimchi or pickle and the like). In addition, the invention lowers pH of the foods to suppress the proliferation of the harmful microbes, and makes the low oxygen/oxygen-free environment using the carbon dioxides produced as metabolism by-products, thereby increasing the flavor of the foods and prolonging the preservation period. | 04-09-2009 |
20090139249 | APPARATUS AND METHOD FOR MAINTAINING FRESHNESS OF FOODS - An apparatus for maintaining the freshness of foods is provided. The apparatus comprises first and second electrodes spaced oppositely to a predetermined distance, a voltage generator unit applying voltage between the first electrode and the second electrode, heat transfer means connected to the first electrode or the second electrode to absorb heat from the space between the first electrode and the second electrode, and a temperature control unit controlling the heat transfer means such that the space between the first electrode and the second electrode is of predetermined temperature, whereby the heat transfer means is connected to the electrode for voltage application, so that both the application of electric field and the temperature regulation are advantageously obtained using a single electrode without installing a separate device for temperature regulation. | 06-04-2009 |
