  • Patent number: 10966293
    Abstract: Processes and systems that enhance the heating of packaged foodstuffs and other items in various microwave heating systems are described herein. It has been unexpectedly found that configuring the microwave heating zone of a microwave-assisted pasteurization or sterilization system so that the article carrier, the microwave launchers, and/or the packages have certain relative dimensions may significantly enhance the uniformity of heating of the articles. The result is pasteurized or sterilized articles that exhibit fewer hot and cold spots, a consistent microbial lethality rate, and desirable end properties, such as visual appearance, taste, and texture.

  • Patent number: 9398644
    Abstract: A radio-frequency heating apparatus includes a phase varying unit to vary the phase of radio-frequency power; and a plurality of antennas which are placed on the same plane in a heating chamber and radiate a plurality of radio-frequency waves. The radio-frequency waves have a predetermined phase difference caused by phase variation in the phase varying unit. A geometry information acquisition unit acquires the geometry of an object; and a control unit controls the phase varying unit so that the radio-frequency waves are in phase in a first mode, and the radio-frequency waves are in opposite phase in a second mode. The control unit switches between the first mode and the second mode based on the acquired geometry information.

    Abstract: An insulating microwave packaging material (200) is formed by bonding a microwave interactive material substrate (205) that creates sensible heat upon exposure to microwave energy to a second substrate (210) along bond lines (212) arranged in a pattern to form closed cells (214). Upon impingement of the insulating microwave packaging material (200) by microwave energy in a microwave oven, the closed cells (214) expand to form insulating pockets (216). One side of the insulating pocket (216) bulges and lofts above the opposite side. When a food product is situated on the insulating microwave packaging material (200), the insulating pockets (216) insulate the food product from the microwave oven environment.

  • Publication number: 20100301041
    Abstract: Disclosed herein is a microwave oven, in which a tray within a cooking room is rectilinearly reciprocated in a lengthwise direction of the cooking room and is rotated, simultaneously, to cook food. This is achieved using a gear assembly including a main gear and a planetary gear. The gear assembly includes the main gear and the planetary gear, which are engaged with each other and are rotated. A diameter of the main gear and a diameter of the planetary gear may be equal to each other, and the main gear and the planetary gear respectively include eccentric shafts. The gear assembly effectively transmits power supplied by a motor to the tray, thereby allowing the tray to be rotated at a uniform speed and to be driven even using a motor having a small load capacity.

  • Publication number: 20100264136
    Abstract: One aspect is a microwave furnace including a conveyor for conveying a first material layer, and a second material layer carried on the first material layer, through the furnace. A microwave heating zone is configured for heating the second material layer with a microwave generator as the conveyer conveys the layers through the microwave heating zone. The second material layer consists of a metal-containing material. A direct heat zone is configured for heating the second material layer with a direct heat source as the conveyer conveys the layers through the direct heat zone. A discharge is provided for discharging the material layers out of the microwave furnace.

  • Patent number: 7804050
    Abstract: A microwave oven in which a power transmission transmitting driving force of a motor moves a tray right and left without direct contact with the tray. The microwave oven includes a support disposed between a bottom plate and the tray to support the tray and the power transmission transmitting driving force of the motor to the support such that the support linearly travels. The shape of an oval guide hole formed in the support is changed to adjust the stopping time of the support at the rightmost or leftmost side. The tray linearly travels together with the support when the support linearly travels. The microwave oven further includes a tray restriction device or a tray moving device for guiding the linear movement of the tray. The tray restriction device and the tray moving device are implemented by locking steps, grooves, protrusions, or rollers.

  • Publication number: 20090200297
    Abstract: There is provided a cooking device having a drawer type automatic door in which delicate control is carried out when the door is opened and closed, whereby an influence (falling, overflowing, or the like) exerted on an object to be cooked such as a food by a shock produced at the time of door opening and closing can be reduced or eliminated. When a before-stop position (full opening detection switch Pso at the time of full opening, intermediate switch Psi at the time of full closing) provided before the stop position of the door is detected by specific position detecting means, speed control means controls driving means to reduce the travel speed of a drawer body. For the door opening and closing at the time of start and finish of cooking, a position at which the drawer body is to be stopped automatically (fully opened position Po, fully closed position Pc) is recognized, and the opening/closing speed leading to the stopping is controlled.

  • Patent number: 7560673
    Abstract: An apparatus for controlling agricultural pests in soil using microwave energy. The apparatus is an agricultural implement having a means for directing a layer of soil from the ground onto a conveyor which carries the soil through a microwave energy application area, and then disperses the soil back onto the ground. The microwave energy heats the soil to a desired temperature which destroys weeds, seeds, and insects in the soil.

  • Patent number: 7507939
    Abstract: Apparatus for cooking food products on both sides thereof, including a base member (2) associated to a bottom heating surface (3) adapted to support food products to be cooked, an upper member (4) associated to a top heating surface (5) and joined in an articulated manner to the base member (2) so that, when the upper member (4) is displaced towards the base member (2), the top heating surface (5) comes to lie opposite to the bottom heating surface (3) so as to enclose the food products therebetween. The upper member (4) is adapted to close in onto the base member (2) so as to form a cooking cavity (6) containing the heating surfaces (3, 5), wherein the cooking cavity (6) defines a radiation shield capable of retaining the microwaves inside the cooking cavity (6) itself.

  • Patent number: 7501608
    Abstract: The present invention provides a microwave oven and a method of operating a microwave oven, which minimises user involvement when heating a food item to a desired target temperature. According to the invention, the initial temperature of the food item is measured prior to the heating process, and the required heating time is determined automatically based on the initial temperature, the target temperature, and the amount of food as entered by the user. In order to heat a food item to a desired target temperature, the user only needs to position a container for temperature measurement and enter the amount of food. In particular, the present invention is preferably adapted for heating of baby food, such as baby milk contained in a baby bottle, and in such case the target temperature is preferably preset to about 37° C.
