ABSTRACT:
A sampling apparatus is characterized by a housing having a bore communicating at one end with the interior of a vessel containing fluidized product. A plunger assembly in the bore has a sample chamber intermediate its ends and is reciprocated to project the sample chamber out of the bore and into the vessel to receive a sample of product therein, and to then retract the sample chamber from the vessel and into the bore to a sample collection point. Forward and rearward seals on the plunger to opposite sides of the sample chamber always maintain a liquid seal between the one end of the bore and the sample collection point. The rearward seal comprises a shear bearing having a circumferential groove that receives and retains fluidized product in sealing relation to the bore to seal the shear beating and thereby the plunger assembly to the bore. The product collection point in the bore includes a plurality of passages in the housing that communicate with the bore and are sized to prevent passage therethrough of relatively large product particles. Upon reciprocation of the plunger assembly to project the sample chamber into the vessel, the shear beating cuts off and conveys back into the vessel any pieces of product that became caught in the passages during the previous sampling cycle and extend into the bore.
