    摘要： There is provided a leak detection system for detecting breaches in sealed food containers (T). The leak detection system comprises air-sample testing equipment configured to test the composition of an air sample provided to the air-sample testing equipment. The food container is conveyed through an air-sampling region using a conveyer belt (702), and a second conveyor belt (701) presses the container from the opposite side of the container. Both conveyor belts have perforations (703). At least one air-sampling port (711, 712) is located inside one of the conveyor belts in the air-sampling region. An air sample conduit is provided extending between the at least one air-sampling port and the air-sample testing equipment. In use, the at least one air-sampling port takes an air sample from the air-sampling region at least during or after the at least one pressing member applies pressure to the sealed food container in the air-sampling region and communicates said air sample through the air sample conduit to the air-sample testing equipment.

    摘要： There is provided a leak detection system (100) for detecting breaches in sealed food containers. The leak detection system comprises air-sample testing equipment configured to test the composition of an air sample provided to the air-sample testing equipment. At least one pressing member (101) is provided configured to, in use, apply pressure to the sealed food container located in an air-sampling region. At least one air-sampling port (102) is located in the air-sampling region. An air sample conduit (51) is provided extending between the at least one air-sampling port (102) and the air-sample testing equipment. In use, the at least one air-sampling port (102) takes an air sample from the air-sampling region at least during or after the at least one pressing member (101) applies pressure to the sealed food container in the air-sampling region and communicates said air sample through the air sample conduit to the air-sample testing equipment.
