A perforated collecting tube located vertically in the air conveyor trough retrieves the sample from the material flow. The perforations in the collecting tube are rotated into the material flow for the purpose of sampling. In the closed condition, the holes are turned in the opposite direction. The collecting tube is driven pneumatically. Once retrieved, the sample can be transported through a discharge tube directly into a downstream process station. The sampling cycle is controlled by the controller of the process station.
