Abstract
A leak detection system for detecting breaches in sealed food containers is disclosed. The leak detection system comprises a first optical sensor configured to transmit a light signal across a first testing path, said first optical sensor being sensitive to gas composition variations. A permeable pressing member is configured to, in use, apply pressure to the sealed food container. The first optical sensor is arranged such that at least a portion of the first testing path along which the light signal is transmitted is located behind or within the permeable pressing member.
Claims21
A leak detection system for detecting breaches in sealed food containers, the leak detection system comprising:
- a first optical sensor configured to transmit a light signal along a first testing path, wherein the first testing path is a path of the light signal, said first optical sensor being sensitive to gas composition variations;
- and
- a permeable pressing member configured to, in use, apply pressure to the sealed food container;
- wherein said first optical sensor is arranged such that at least a portion of the first testing path along which the light signal is transmitted is located within the permeable pressing member.
A method of detecting breaches in sealed food containers, the method comprising:
- applying pressure to a sealed food container using a permeable pressing member;
- detecting a variation in gas composition behind or within the permeable pressing member using a first optical sensor configured to transmit a light signal along a first testing path, wherein the first testing path is a path of the light signal;
- wherein said first optical sensor is arranged such that at least a portion of the first testing path along which the light signal is transmitted is located within the permeable pressing member.
A leak detection system for detecting breaches in sealed food containers, the leak detection system comprising:
- a first optical sensor configured to transmit a light signal along a first testing path, wherein the first testing path is a path of the light signal, said first optical sensor being sensitive to gas composition variations;
- and
- a permeable pressing member configured to, in use, apply pressure to the sealed food container;
- wherein said first optical sensor is arranged such that at least a portion of the first testing path along which the light signal is transmitted is located behind the permeable pressing member relative to a side of the permeable pressing member configured to come into contact with the sealed food container or is located within the permeable pressing member;
- wherein the permeable pressing member comprises a first permeable conveyor belt;
- and wherein the first permeable conveyor belt comprises an array of elements that project away from the surface of the conveyor belt for contacting the sealed food container and separating a body of the conveyor belt from the surface of the sealed food container.
