ABSTRACT:
A discrete volume vacuum sampling device is provided with a vacuum tube, a sample tube, and a sample container. The container defines a discrete volume of product to be sampled from a product bed within a processing machine. The sampler tube extends between the container and the machine containing the product to be sampled. When a vacuum is applied through the vacuum tube, a door on the container is pulled shut, thereby increasing air velocity in the sampler tube, so as to draw product from the bed upwardly through the sampler tube and into the container. When the container is full, the vacuum is stopped, such that the weight of the product in the container pushes the door open for discharge of the discrete volume of product sample, while product remaining within the sampler tube is discharged back into the bed of material within the machine.
