呼ばれる小さな孔があいてしまうという問題がある。By the way, generally, the holes in the bottom plate of this type of food processing machine tray are punched by a pressing device so that a large number of holes can be formed at the same time. Therefore, as shown in FIG. 6, when the bottom plate b is punched with the punching punch a, the peripheral edge of the opening on the surface side of the hole c is dented along the punching direction X of the punching punch a. Although a tapered recess d is formed on the peripheral edge of the opening on the front surface side, burrs e are formed on the back surface side of the hole c along the punching direction X of the punching punch a. For this reason, if the burrs e produced during the punching process are left as they are, there is a risk of breaking the pouch with the burrs e. In the past, the burr e produced in a large number of holes c by a disc grinder or the like is scraped off one by one. Processing was required. For this reason,
There is a problem that work efficiency is poor. Further, even if the burrs e produced in a large number of holes are individually shaved off by a grinder or the like, the burrs e cannot be surely removed, and the protruding burrs e may remain slightly. Therefore, in the conventional food processing machine tray, the surface on which the burr e is generated is formed so as to face the back surface side, so that the surface on which the recessed portion d is formed faces inward to prevent damage to the pouch. , Not only causes various troubles such as germs to accumulate on the burr e and propagates the germs, but at the time of the above-mentioned sterilization step, since a plurality of trays are stacked in multiple stages to sterilize many processed foods at the same time, There is a problem that the burr e hung vertically from the back surface of the pouch causes fine scratches and small holes called pinholes in the lower pouch.
