A bucket elevator carried the ground grain from roller mills to the plansifter where horizontal layers of oscillating sieves separated it into various sizes, or grades, for further grinding. Suspended by maple rods, the plansifter oscillated horizontally driven by a mechanism on the floor.
	Split into two parts, the plansifter is disassembled for the move to the Twin Cities. The top goes through a hole in the roof of the Albany building. Canvas socks (as seen in the picture above) connected the chutes in the top and bottom pieces. The bottom part remains on the floor in the picture below.
Shindelar and Machin discuss disassembling and moving the plansifter, which was patented in 1890 and 1892.
	This middlings purifier was built by Edward P. Allis Co. of Milwaukee about 1900. The purifier received cracked bran from the roller mills, separated the impurities using a vibrating sieve, and removed the light bran with air blasts and suction. The purified middlings were then passed on for re-grinding.
To remove the equipment, the crew had to cut a hole in the roof of the mill building.
	A crane lifts the purifier through the roof of the mill building to a waiting truck.
