（産業上の利用分野）
本発明は、包装麺等のマイクロ波加熱殺菌に関
するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to microwave heat sterilization of packaged noodles and the like.
（従来の技術）
一般にマイクロ波加熱殺菌装置は、
(イ) 食品だけを発熱させるが、包装材は発熱させ
ない。(Prior art) Generally, microwave heating sterilizers (a) generate heat only in the food, but not in the packaging material.
(ロ) 均一な加熱がし易い。(b) Easy to heat uniformly.
(ハ) 装置が蒸気殺菌（レトルト）に比較して簡単
である。(c) The equipment is simpler than steam sterilization (retort).
等の理由から幅広く利用されている。It is widely used for these reasons.
（発明が解決しようとする問題点）
しかしながら、包装麺等の場合、完全にシール

高となり実用的ではないものとなる。(Problem to be solved by the invention) However, in the case of packaged noodles, etc., if they are heated in the microwave after being completely sealed, the air inside
The bag may burst due to the increased pressure of the steam generated. From this point of view, steam sterilization (retort) is effective because it allows heat sterilization under pressure, but steam sterilization requires large-scale equipment and is relatively difficult for packaged noodles, especially boiled noodles. Since the number of days it can be stored is only for a short period of time, the cost becomes high and it becomes impractical.

点の解決を図つている。(Means for Solving the Problems) In view of these points, the present invention is designed to prevent the bag from bursting even when heated by microwaves. Immediately after heat sterilization using microwaves, the opening of the bag body of packaged noodles, etc. is to be sealed quickly and reliably. A bucket belt with an inclined frame is installed on the conveyor that passes through the interior, and a seal roll is installed on the outside of the conveyor exit side of the cavity at a position close to the cavity and above the conveyor at a position corresponding to the highest position of the inclined frame of the bucket. This problem is solved by providing a receiving part on the lower side.

漏洩電波を極力少なくするためである。 On the belt conveyor 1, buckets 2 on which packaged noodles, etc. are placed are arranged in rows (one row or multiple rows) at regular intervals.
Most of the belt conveyor 1 is covered with a reflector plate 4 centered around a microwave heating sterilization cavity 3.
The purpose of making the conveyor 1 as long as possible and covering most of it with the reflecting plate 4 is to minimize leakage of radio waves in the horizontal direction.

ークライトのような他のプラスチツクでもよい。 Cavity 3 is a sealed metal box that heats food such as packaged noodles using radio waves emitted from a magnetron.
A stirrer 5 is provided to make the electric field within the cavity 3 uniform. On the outside of the cavity 3 on the exit side of the belt conveyor 1, a seal roller 6 for heat sealing is provided on the upper side of the belt conveyor 1, and a receiving roller 7 is provided on the lower side, in the vicinity of the cavity 3. This receiving roller 7 may alternatively be a bar. The bucket carts 2 installed in a row on the belt conveyor 1 have an inclined frame 8 as shown in FIG. Plastic is best for this purpose, and Teflon is the best in terms of heat resistance and abrasion resistance, but in the case of packaged noodles, the sterilization temperature may be relatively low, so other plastics such as Bakelite may also be used.
この傾斜枠８とシールローラー６と受ローラー
７との関係は、傾斜枠８の最高位の位置に対応す
る位置の上側にシールローラー６があるように配
設されている。 The relationship between the inclined frame 8, the seal roller 6, and the receiving roller 7 is such that the seal roller 6 is located above the position corresponding to the highest position of the inclined frame 8.
包装麺は第４図のように３方がシール９され一

意され、その開放端の一部がスポツトシール１１
された状態で、その開放端部をバケツト２の傾斜
枠８の最高位の辺縁に載置されて送られる。 As shown in FIG. 4, the packaged noodles are stored in a bag 10 that is sealed on three sides and left open on one side, and a part of the open end is sealed with a spot seal 11.
In this state, the open end thereof is placed on the highest edge of the inclined frame 8 of the bucket cart 2 and sent.
キヤビテイ３内に送られた包装麺は、マイクロ
波加熱によつて殺菌される。 The packaged noodles sent into the cavity 3 are sterilized by microwave heating.
このとき、加熱によつて内部の蒸気の圧力が上
昇しても、傾斜した上方の開放端部から排出され
るから、袋体が破裂することはない。 At this time, even if the pressure of the internal steam increases due to heating, the bag will not burst because it will be discharged from the slanted upper open end.

ールが可能である。 The heat-sterilized packaged noodle bag is sent out of the cavity 3, is supported by a receiving roller 7 as shown in FIG. 3, and the open end is sealed by a heat roller 6. Roller heaters are better than bar heaters because packaged noodles are conveyed continuously on a belt conveyor, and line seals are easier to pressurize and can seal uniformly.

殺菌と同等の効果を有するものである。(Effects of the Invention) The present invention is a method of sterilizing foods using microwave heating, which heats only the food without heating the package, and the heating is uniform and the equipment is relatively simple. Instead of steam sterilization (retort), which was used to sterilize packaged noodles, etc., a bucket container with an inclined frame attached to a belt conveyor was used to prevent the rise in steam pressure inside the packaging bag due to microwave heating. By placing the open end of the packaging bag at the highest position of the inclined frame and sending it, the packaged noodles, etc. inside the bag are kept in a stable state and will not leak out, and will rise due to heating. The bag is not ruptured by the air and steam pressure generated, and the sealing position is placed immediately after the bag leaves the cavity of the microwave heating device, so the sterilizing effect is sufficient to prevent bacteria from entering. It is possible to obtain packaged products such as packaged noodles that are extremely hygienic and do not lose their shape, require relatively simple equipment, and have the same effect as conventional chemical sterilization such as H 2 O 2 . It is.
