ことになる。2. Description of the Related Art Trays conventionally used in retort sterilizers have punched holes in their bottom plates, and are made of aluminum or stainless steel plates. Furthermore, for bags and bottles for heating and sterilizing medical infusions, the height of the side walls of the tray is relatively high, and the gas phase portion is 10% or more of the height of the tray.

に取入れるようにしている。FIG. 7 shows a conventional example in which the distance C (interval) between the container 28 placed in the tray 27 and each stacked bottom plate 29 is large, and hot water etc. is spouted from the side wall of the tray. In a spray retort that sterilizes food by heating, the gap d between the trays is large enough to take in the spray ejected from the side wall.

る品物の取込みが困難となる難点がみられた。Problems to be Solved by the Invention Among the conventional trays as described above, there are trays with relatively high side walls such as trays for bags and bottles, where the gas phase portion is 10% or more of the height of the tray, and trays for bags and bottles. , with a retort container with a large gap C between the trays, when the retort container is filled with water, the bag or bottle may float up in the tray or the bag may move horizontally, and if this movement exceeds the limit, the tray may The position of the items that had been lined up and loaded inside the container changed significantly, making it difficult for the automatic conveyance line to take in the items after the heat sterilization process.
このような難点を解消しようとして、トレイ間の隙間を
縮めると品物の浮き上がりは防止できるがスプレーの均
一散布が困難となり、均一加熱を阻害することになる。In an attempt to solve this problem, reducing the gap between the trays can prevent the items from floating, but it makes it difficult to uniformly distribute the spray, which impedes uniform heating.

換する際に品物がトレイ上を移動する難点がある。In particular, in the spray retort sterilization method, a method of replacing inert gas such as nitrogen gas (for example, Japanese Patent Application Laid-Open No. 57-20
6447 and Japanese Patent Application No. 2-103714), deoxygenation is carried out by filling with water, but there is a problem in that the articles move on the tray during this filling with water.
又、各品物毎に仕切りを入れる方法も考えられているが
、トレイの製作に手間と時間がかかり高価となる欠点も
生じる。Also, a method of inserting partitions for each item has been considered, but this method also has the drawback that it takes time and effort to manufacture the trays, making them expensive.

二重底トレイとした。Means for Solving the Problems In order to achieve the above object, the present invention provides, as a first invention, a second bottom plate having a number of punched holes at a certain distance from the bottom surface of a tray having punched holes in the bottom plate. It was made into a double bottom tray.
第２発明はスプレーを効率よくするため、第２の底板の
パンチング孔が４隅の角から中央へ向かう長孔群である
二重底トレイとしたものである。The second invention is a double-bottomed tray in which the punching holes in the second bottom plate are elongated holes extending from the four corners to the center in order to improve the efficiency of spraying.

The bottom plate is supported by support rods and has no side walls, and the second bottom plate has a large number of punched holes, so spray ejected from the side walls or the four corners can be uniformly dispersed without any obstruction. It is sprayed through a number of punched holes onto the bottles and bags placed on the tray below. or,
When multiple stacks are stacked, the second bottom plate of the double bottom is located close to the container, which prevents the container from lifting or moving even when the retort is operated with full water. When moving to the next process after completing heat sterilization, cooling processes, etc., the bottles and bags do not move significantly and disrupt the alignment as in conventional cases, and it is easy to use for the full water displacement degassing method. It also has many benefits such as ease of automation of the conveyance line.
