[0002] During the flour processing process, or after the flour is processed and stored in the flour silo, it is necessary to sample and test it to ensure the safety of food. Most existing flour sampling devices are in the form of sampling rods or sampling cylinders (such as patent CN215492671U), with a sampling port on the side wall. The sampling cylinder is inserted into the flour, the sampling port is opened, and the flour falls into the sampling port. When this type of flour sampling device is inserted into the flour, it will squeeze the flour, resulting in increased friction resistance in the flour. When the sampling port is opened, the flour is not easy to fall into the sampling port, and the sampling effect is poor; and the structure is complex and inconvenient to clean.

Then the driving rod is pulled out and the rod is removed. The flour sample will stay in the sampling part. The sampling part is lifted by picking up the support shaft to send the flour sample for inspection. S5. After the flour sample is sent for inspection, use an air gun to blow and clean the plug rod, plug plate, sampling part and driving rod respectively, and then soak them in disinfectant after blowing; S6. Dry each component and store it for processing.

[0011] Furthermore, in step S5, when the plug rod is purged, the outer surface is first preliminarily purged, and then the plug plate is inserted into the slot, the air gun is inserted into the socket at the top of the plug rod to inflate, and then the plug plate is gradually pulled out to expose each sampling slot, thereby achieving the purge of the sampling slot.
