JPH05103610A - Apparatus for instantaneous sterilization of vinegared rice packed in chip box - Google Patents

Abstract

PURPOSE:To provide the subject apparatus for instantaneously sterilizing vinegared rice packed in a chip box and covered with a transparent vinyl sheet by synergistic effect of ultraviolet ray and microwave by irradiating the vinegared rice with ultraviolet ray simultaneous to the application of a pulse of microwave. CONSTITUTION:When the output of a microwave oscillator 1 is applied through a microwave antenna matching part 2, the upper ultraviolet lamps 3 and the lower ultraviolet lamps 4 are lighted by the applied electrical field. A vinegared rice packed in a chip box 5 and covered with a transparent vinyl sheet is placed between the upper and the lower lamps and ultraviolet ray is radiated into the sterilization chamber 6 simultaneous to the application of the microwave.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for instantly sterilizing packed sushi.

[0002]

2. Description of the Related Art A folded sushi is one in which raw fish, shellfish, etc. are used to keep bacteria at a low temperature so that they can be spoiled rapidly with the passage of time. Also, in the process of making sushi, sterilization in the air is attached, and pathogenic bacteria are easily proliferated due to human handing down. Up until now, there has been no consideration for preventing this, and the only way to eat was in a very dangerous state.

[0003]

[Problems to be Solved by the Invention] In order to slow down the decay of the packed sushi, the concentration of vinegar in sushi rice is increased, and the amount of bean paste put in the sushi rice is increased. No significant effect has been obtained.

[0004]

[Means for solving the problem] Then, the packed sushi is covered with a transparent vinyl sheet and irradiated with ultraviolet rays from the outside to kill the bacteria adhered to the surface of the sushi, and further to prevent the bacteria from adhering to the outside. It is possible to prevent the adhesion of. However, it cannot be expected to have an effect on the fungus in the shaded area where the ultraviolet rays do not reach. Similarly, it is possible to sterilize folded sushi by isolating it from the outside air and shock-applying high frequency waves, especially microwaves, but this alone requires a long application time to complete its sterilizing effect. Since it is necessary to sprinkle it, there is a drawback that the sashimi is heated and the taste changes.

[0005]

Therefore, by carrying out both of these methods simultaneously, the effects work synergistically and sufficient results can be obtained. In addition, by driving the ultraviolet lamp for ultraviolet irradiation by applying this microwave, the device can be simplified and stabilized.

[0006]

EXAMPLES Examples of the present invention will be described below. When the output of the microwave oscillator (1) is applied by the microwave antenna matching section (2), the ultraviolet lamp upper part (3) and the ultraviolet lamp lower part (4) are turned on by the applied electric field. By placing a sushi pack (5) covered with a transparent vinyl sheet in the upper and lower lamps, a microwave is applied to the inside of the housing (6) and ultraviolet rays are simultaneously irradiated. As a result, it is possible to kill the bacteria attached to the folded sushi in a very short time. Therefore, since the sushi is not heated, the taste of the sushi is not changed and the sushi that has been packed is prevented from decaying.

[0007]

[Effect] According to the above-mentioned embodiment, when the sushi folding covered with the transparent vinyl sheet is applied for about 2 seconds and not applied, it takes about 12 hours at a room temperature of about 20 ° C. Although it was putrefaction, the taste of the applied product did not change, and it was possible to eat without putrefaction even after about 48 hours. Therefore, it was proved that the sterilization of sushi stuffing was sufficiently effective without changing its taste.
