【発明の詳細な説明】
本発明は食品の真空包装体のマイクロ波殺菌方
法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for microwave sterilization of vacuum packaged food products.
従来真空包装食品は殺菌のためレトルト式に加
圧下で加熱殺菌しないと包装材が破損するが、こ
の方法であると装置が大型となり、また取扱が煩
雑を極める。 Conventionally, vacuum-packaged foods are sterilized unless they are heated and sterilized under pressure in a retort type, otherwise the packaging material will be damaged, but this method requires large equipment and is extremely complicated to handle.
本発明はこのような欠点を解決するのみならず
コンベアベルト上で多量生産ライン化できる殺菌
方法を提供するものである。 The present invention not only solves these drawbacks, but also provides a sterilization method that can be used in a mass production line on a conveyor belt.

菌する方法である。 In the present invention, a large number of heat-resistant molding retainers made of Teflon, polypropylene, etc. with open upper and lower surfaces are arranged on a conveyor belt as shown in the explanatory view of FIG. A microwave-transparent and heat-resistant presser belt that can press the open top part of the retainer is provided separately, and the vacuum-packed food package is housed in the retainer, and the top and bottom of the retainer are held between the conveyor belt and the presser belt. This method continuously sterilizes vacuum-packed foods by passing them through a microwave heating area under normal pressure.

are housed one after another, and the retainer 1 is passed through a microwave heating area 5 while being pressed and clamped on the upper and lower surfaces by another endless holding belt 4 made of microwave-transparent plastic that can press the upper surface of the retainer, and then air-cooled or water-cooled. The food package 3 is transferred to a delivery belt 7 through a cooling zone 6 and sent to the main cooling section, where it is continuously sterilized by microwaves at normal pressure. If a mesh belt is used for the conveyor belt 2, the cooling is quick, and if the conveyor belt 2 is passed through a cold water shower, the cooling is even more efficient and the internal pressure of the package can be suppressed. If the belt is a plate belt, the pressure generated can be reduced by providing holes in the retainer to release air. More force than necessary is required to press and hold this sealed retainer. A force of 3 kg/cm 2 is required to suppress the vertical force caused by internal pressure expansion, and in order to apply this force to the conveyor, the belt must be tightened strongly or the belt must be tightened as shown in the explanatory diagram in Figure 3. It is preferable to strengthen it with a thick Teflon plate 8 in addition to strongly tensioning it. Further, as shown in the explanatory diagram of FIG. 4, the belt is placed on which a small Teflon roller 9 is connected. The reason why Teflon is used is that it transmits microwaves, has a small coefficient of friction, has good heat resistance, and has good abrasion resistance. It is preferable to use Teflon or a Teflon-coated belt for the belt 2.

らない。 In this way, in the method of the present invention, the vacuum-packed food package inside the retainer is held down by the presser belt and the conveyor belt, so even when microwave heating is performed, the bag is prevented from being torn due to a temperature rise. Microwaves can sterilize food packaged under pressure very efficiently.Moreover, microwaves can sterilize foods at a temperature of 125°C in 2 minutes, and sterilization can be achieved by simply passing through the microwave heating area in a short time using a conveyor belt system. It is sufficient that the food packaging does not break at all.
