JPH06269253A - Device for thawing frozen hand-rolled 'sushi' with microwave oven - Google Patents

Abstract

PURPOSE:To provide an inexpensive thawing device capable of thawing the rice part at a high temperature and the topping part at a low temperature in the case of thawing a frozen hand-rolled SUSHI (vinegared rice) with a microwave oven and giving a thawed SUSHI having a rather warm rice part and a cold topping and giving excellent feeling to the palate. CONSTITUTION:A thin plate of e.g. aluminum for reflecting and shielding the microwave of a microwave oven is bonded to a vessel (b) made of a synthetic resin such as a plastic except from the part 1 to pass the microwave. The top lid (a) is made of a material same as that of the vessel (b). The top face is covered with aluminum foil, etc., to shield the microwave leaving an elliptic window at the center to allow the transmission of microwave. The faces 2 to 5 are free from aluminum foil, etc. The top lid (a) is closed after putting a frozen SUSHI, etc., into the vessel (b), the vessel is put into a 100V 500W microwave oven and the SUSHI is thawed by the irradiation with microwave. The rice is heated at a high temperature while keeping the topping part at a low temperature by this process.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a defroster according to the present invention for rapidly thawing an iron-fired rice bowl or a salmon roe bowl containing domestic or commercial frozen nigiri sushi and raw fish in a few minutes. Put sushi and rice bowl in a microwave oven and radiate microwave in a microwave oven for a while to make the upper fish cold and the lower rice warm thaw.

2. Description of the Related Art In conventional thawing using a microwave oven, it is difficult to select a permissible time for irradiating a microwave, and it is difficult to use a microwave oven on the market, and a specialized machine with special specifications is required. Moreover, the sushi after defrosting is
The temperature of the seed and the rice was the same, the rice was slightly warm, and the rice was cold, so there was no difference in the temperature at which the nigiri sushi tasted good, and the taste was significantly reduced.

[0003]

The defroster according to the present invention is capable of easily and deliciously defrosting frozen sushi in correspondence with general commercially available microwave ovens, and is currently a special one that costs 100,000 yen per unit. A few without using a microwave
By using this unit together with a microwave oven that costs as low as ten thousand yen, it is intended to solve the problem so that the objective can be achieved at a price of several thousand yen.

[0004]

According to the present invention, microwaves are blocked except for a part of the bottom of a container made of a material through which microwaves of a microwave oven can pass, such as plastic that can be stored in a microwave oven. Make the structure Next, the upper lid is made of the same material as that of the lower container, but the central portion of the upper surface and the other four surfaces have a structure through which a cyclone wave can pass. Frozen sushi or the like is placed in such a container and the upper lid is closed, and cooking or strong electricity is timely applied in a microwave oven. At that time, the microwave irradiates the inside of the container substantially evenly in a plane, but there is an unbalanced irradiation between the upper and lower parts, and a temperature difference occurs between the upper part and the lower part.

[0005]

Function: The temperature rises from low to high. Therefore, the frozen sushi is thawed in the cold, raw sushi seeds. , Thaw the bottom rice warmly. By the way, 100v500w
In the microwave oven, frozen sushi of 22 g of tuna, 13 g of tuna, and 35 g of one piece is thawed in 17 seconds when the initial temperature is 18 degrees below zero, and is cold in the top and warm in the bottom.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory diagram of an embodiment of a decompressor of the present invention. (B) A container made of synthetic resin such as plastic is adhered by a thin plate such as aluminum except for the portion (1) so as to reflect and block microwaves of a microwave oven.
(A) The upper lid is of the same quality as the (b) container, and the upper surface is
(1) The microwave of the microwave oven is allowed to pass through the elliptical shape in the central portion, and the other portions are blocked with aluminum foil or the like so as not to pass through. Nothing is attached to the four faces of (2), (3), (4), and (5).

[0007]

The decompressor according to the present invention is 100V500.
When thawed in a microwave oven with W output, frozen Nigiri sushi (18 ° C below initial temperature) 10 pieces 350g for 2 minutes 50
Thaw in seconds. At that time, the temperature of the sushi is about 11 degrees in the part where the temperature difference is large, about 36 degrees in the rice, and about 11 degrees and 25 degrees in the part where the temperature difference is small.

[Brief description of drawings]

FIG. 1A is an explanatory view showing the structure of an upper lid and FIG. 1B shows the structure of a lower container.

[Explanation of symbols]

(A) 1 is the ultra-high-wave passage portion of the upper lid, 2, 3, 4, 5 are the other four surfaces ... (b) 1 is the ultra-high-wave passage portion of the lower container.

Claims (1)

[Claims] 1. When thawing frozen nigiri sushi with a microwave oven, rice and sushi seeds can be thawed at different temperatures, that is, the rice portion can be thawed at a high temperature and the sushi seed portion at a low temperature. .
