  • Patent number: 9237756
    Abstract: A method for preparing and conditioning granular burdock through combined uniform drying by using radio frequency (RF) pretreatment and microwave pulse spouting is provided. The process of the present disclosure includes performing pretreatment on fresh burdock, protecting color, pre-drying by RF, drying through microwave pulse spouting, and packaging. The color and luster of a product are greatly improved after color protection, the RF pre-drying treatment may be performed for 20 minutes, and hot air drying treatments for removing moisture on the surface may be performed for 60 minutes. The method has a short drying time and high efficiency. The sectional microwave pulse spouting treatment needs 60 minutes totally, while the complete hot air drying treatment needs 400 minutes. Therefore the drying time of the method is greatly shortened, and the drying is uniform, and a sample after microwave pulse spouting drying has strong fragrance.

  • Publication number: 20090011101
    Abstract: A combination oven includes convection, steam and microwave cooking sources. When implementing a user selected cooking program using the microwave source and at least one of the other sources, the oven control is configured to implement the cooking program in a manner using an input food product mass value to set microwave energy level applied to the food product during operation of the cooking program and without changing cook time as set by the cooking program. The microwave energy level may be set such that end product achieved without changing cook time has a comparable degree of doneness regardless of mass. The oven control, or a separate computerized device, may be used to automatically convert a non-microwave cooking program into a microwave enhanced cooking program that is stored by the oven control for selection by an operator.

  • Publication number: 20080296292
    Abstract: The present invention relates to a heater assembly for a microwave oven. A heater assembly for a microwave oven according to the present invention comprises a ceramic heater and a halogen heater for providing heat used for cooking food in a cooking chamber provided in a cavity assembly; a heater supporter fixed to a side of the cavity assembly, with the ceramic and halogen heaters fixed to the heater supporter; and a reflection plate provided above the ceramic and halogen heaters to reflect heat of the ceramic and halogen heaters to the cooking chamber, wherein a portion of the reflection plate corresponding to the ceramic heater is open in its longitudinal direction. According to the present invention, there are advantages in that contact between a heating wire of the ceramic heater and the reflection plate is prevented and the heat dissipation of the ceramic and halogen heaters is obtained by means of airflow that is generated by a cooling fan assembly for cooling electric parts.

  • Publication number: 20080283519
    Abstract: The present invention is directed to improving the conventional high-speed cooking oven based on a combination of hot air impingement and microwave heating by providing a time-dependent spatial variation in the net air impingement and/or net microwave energy applied to the food product in the oven. This is aimed at optimizing heat transfer and microwave efficiencies in a high-speed cooking oven, thereby enabling the oven to deliver an optimal cooking efficiency in comparison to the conventional high-speed cooking oven. In addition, under the present invention, the cooking efficiency may be further optimized by dimensioning the nozzles for hot air impingement to tighten impingement plumes, subject to the space constraint of the oven's cooking chamber, and dimensioning the cooking chamber of the oven in integer multiples of the wavelength of the microwave energy to match the microwave load.

  • Patent number: 7449665
    Abstract: Apparatus for cooking food products on both sides thereof, comprising a base member associated to a bottom heating surface, a first electric heating element located between the base member and the bottom heating surface, an upper movable member associated to a top heating surface, a second electric heating element located between said upper member and said top heating surface, and one or more microwave generators housed in the base member; when said upper member is lowered, the top heating surface comes to lie opposite to the bottom heating surface so as to form a cooking cavity therebetween. Said first electric heating element is separated from the bottom heating surface by a hollow space and the microwave generator is placed in such position, with the use of appropriate wave-guide means, as to allow the microwaves issuing therefrom to propagate towards said hollow space and, eventually, towards the bottom surface of said bottom heating surface.
