A gas burner for a cooking appliance is a gas burner including a head, an injector holder, a Venturi tube, and an injector, wherein a pair of first Venturi tubes each directly communicate with one of expansion chambers separately formed in the injector holder, each of the expansion chambers communicates with an outer annular chamber through an upright vertical channel thereof, an upper surface of the injector holder is flat, and a second injector is positioned higher than the upper surface of the injector holder and is open.

Gas burner

The present disclosure relates to a cooking apparatus including a heating device, a gas passage to guide gas supplied from the outside to the heating device, a gas valve configured to supply gas to the gas passage, a modulating valve configured to adjust the degree of opening of the gas passage, a boosting passage formed to be branched from a first portion of the gas passage and joined to a second portion of the gas passage positioned in the rear of the first portion along a direction in which gas in the gas passage flows, a boosting valve configured to open and close the boosting passage, a first nozzle disposed between the first portion and the second portion of the gas passage, and a second nozzle disposed between the second portion of the gas passage and the heating device.

Cooking apparatus and control method thereof

Provided is a cooking apparatus including a first heating unit that has a first hole and generates heat using a first heat source, a second heating unit that is arranged to be stacked on the first heating unit, has a second hole formed at a position corresponding to the first hole, and generates heat using a second heat source, and a temperature detection unit that is arranged to protrude to the outside of the second hole while being arranged in the first hole of the first heating unit and the second hole of the second heating unit, and detects a temperature of a cooking vessel when the cooking vessel is brought into contact with the temperature detection unit. The output of each of the first heating unit and the second heating unit is controlled at levels of multiple stages by detecting a temperature of a lower portion of the cooking vessel, and food is cooked at an optimum temperature, thereby improving the taste of the food resulting in improved user satisfaction. The first heating unit and the second heating unit is operated together, so that it is possible to prevent emission of the heat of the second heating unit to the outside by the heat generated by the first heating unit, thereby reducing energy consumed in the second heating unit while increasing the heating rate.

Cooking apparatus

A gas oven configured to use a single cooking cavity being divided into a plurality of individual cooking cavities by mounting a divider at the cooking space. The gas oven includes a forced air supplying device capable of forcedly supplying air to the individual cooking space at an upper portion of the cooking space, and a natural air discharging device capable of naturally discharging waste air of the individual cooking space at a lower portion of the cooking space, when each individual cooking space is shut off by the divider.

Gas oven

A gas oven having a gas supplying passage to supply gas to a burner is provided. The gas oven includes an ON/OFF valve to open/close the gas supplying passage, and a flow rate modulating valve connected to the ON/OFF valve in series so as to change the cross-sectional area of a passage, thereby supplying a proper amount of gas to a cooking cavity in response to the change of a cooking area. When a cooking cavity is divided into individual cooking cavities while a divider is mounted, the flow rate modulating valve is open/closed at a smaller opening degree than the maximum operating degree, and thus may be able to prevent a cooking substance from being carbonized in the individual cooking cavities.

The present invention relates to an improved method for synthesizing meropenem trihydrate[(1R,5S,6S)-2-[((2'S,4&#x2032;S)-2&#x2032;-dimethylaminocarbozyl)pyrrolidin-4&#x2032;-ylthio]-6-[(R)-1-hydroxyethyl]-1-methylcarbapen-2-em-3-carboxylic acid, trihydrate], which is a novel carbapenem antibiotic.

Method for preparing meropenem using zinc powder

The present invention relates to a process for preparing Crystalline Form A of Lansoprazole. Specifically, the present invention relates to a process for preparing highly pure Crystalline Form A of Lansoprazole in a large scale without any additional conversion step, even by using ethanol in which Crystalline Form B is easily formed.
