Food processing system, apparatus for testing a foreign object sensor and a method for operating the food processing system

1. A method comprising:

providing a food processing system including:

a chute portion including a chute body defining a passage;

a foreign object sensor adjacent to the chute portion, wherein the foreign object sensor and the chute portion cooperatively form a foreign object sensing zone within the passage;

a sensor testing conduit having a first end defining an entrance opening disposed outside of the chute body and a second end defining an exit opening disposed within the passage adjacent to or within the foreign object sensing zone; and

a sensor testing implement including a shaft extending from a first end to a second end, the second end of the shaft of the sensor testing implement configured to be selectively inserted through the passage of the sensor testing conduit and into the foreign object sensing zone;

forming a bag;

metering an amount of foodstuff material into the bag through the chute body;

while the amount of foodstuff material is metered into the bag;

inserting the shaft of the sensor testing implement through the sensor testing conduit via the entrance opening, whereby the second end of the shaft extends from the exit opening and is positioned within the foreign object sensing zone; and

utilizing the foreign object sensor for monitoring for presence of the sensor testing implement within the foreign object sensing zone; and

processing the bag as a reject bag when the foreign object sensor does not detect the presence of the sensor testing implement within the foreign object sensing zone.

2. The method according to claim 1 further comprising:

utilizing a food scaling portion for metering the amount of foodstuff material;

utilizing a food bagging portion for forming the bag; and

utilizing the chute portion for guiding the amount of foodstuff material, wherein the chute: portion connects the food scaling portion to the food bagging portion; and

arranging the foreign object sensor about the chute portion.

3. The method according to claim 1 , wherein processing the bag as the reject bag includes:

sealing an open, non-sealed upper end of the bag; and

conveying the sealed bag to another location.

4. The method according to claim 1 , wherein the processing the sealed bag includes

removing the reject bag from a conveyor portion.

5. The method according to claim 1 , wherein processing the bag as the reject bag includes spraying the reject bag with an ink indicating that the bag is the reject bag.

6. The method according to claim 1 , further comprising, when the foreign object sensor does not detect the presence of the sensor testing implement, actuating an alarm.

7. A method comprising:

forming a bag;

metering an amount of foodstuff material into the bag through a chute portion;

while the amount of foodstuff material is metered into the bag;

inserting a shaft of a sensor testing implement through a sensor testing conduit disposed within the chute portion, a first end of the sensor testing implement being arranged within the chute portion and a second end of the shaft being arranged outside of the chute portion, and

utilizing a foreign object sensor for monitoring for presence of the sensor testing implement deliberately in a foreign object sensing zone formed by the foreign object sensor;

withdrawing the sensor testing implement from the foreign object sensing zone through the sensor testing conduit; and

processing the bag as a reject bag when the foreign object sensor does not detect the presence of the sensor testing implement inserted within the foreign object sensing zone.
