The propolis collecter I once saw was like a queen exluder with much smaller mesh (I think it was just window screen). This device was placed over the top super of a full hive. The bees filled the mesh with propolis which was harvested by placing the collecter in the deep- freeze. When frozen, the propolis was easily cracked off the mesh.
