Claims (5)

  Each can lid that is fed continuously is transported at non-contact / equal intervals so that the lid surface is substantially orthogonal to the direction of travel by the transport screw, and each is a chemical spray section defined as an independent space In a can lid sterilizing device that is sterilized by sequentially passing through a hot air heating unit and then continuously sent to the can lid winding device, the direction of travel of the can lid is downward in the sterilizing device. The can lid sterilization apparatus is characterized in that the entire sterilization apparatus is installed so as to be inclined.   A pair of conveying screws are provided on both the left and right sides of the can lid to be conveyed. In the chemical solution spraying part spraying the chemical solution from above on each can lid, the conveying screws are conveyed by the conveying screws on the left and right sides. The can lid sterilizer according to claim 1, wherein a guide member for guiding the upper portion of the can lid is not provided for the can lid.   A cooling / washing unit for cooling and washing each can lid heated by the hot air heating unit with spray of aseptic water and a cooling / washing unit sprayed on the can lid on the downstream side of conveyance from the hot air heating unit The can lid sterilizing apparatus according to claim 1 or 2, wherein a drainer for removing aseptic water is disposed. A feed stopper for shutting off the supply of the can lid is provided on the upstream side of the chemical spraying part, and the sterilized can lid is excluded from the transport path on the downstream side of the hot air heating part. A can lid sterilizing apparatus according to any one of claims 1 to 3 , wherein a reject mechanism is provided. For the clean booth with a high level of air cleanliness where the can lid clamping device is installed, a can lid sterilizer is installed so that the downstream side of the transport is in the clean booth than the hot air heating unit, Because the inside of the clean booth is always maintained at a higher atmospheric pressure than the outside, a can lid conveyance path that connects the inside and outside of the clean booth through the chemical spraying section and hot air heating section allows outside air to enter the clean booth. The can lid sterilizer according to any one of claims 1 to 4 , wherein the device is not allowed to flow.
