1905 Official Gaz. (U.S. Patent Office) 26 Dec. 2502/1 Shaking-Bolts. Barnard & Leas Manufacturing Company, Maline, Ill. Plansifter.
1908 Engineering 2 Oct. 429/2 Flour was dressed through long reels, called ‘bolters’, some of which were about 20 ft. long. These cumbersome machines..have given way in this country to the more adaptable centrifugal dresser, and on the Continent to the plansifter.
1936 J. H. Scott Flour Milling Processes ix. 200 The type of plansifter used..in this country is the free-swinging, balanced crank pattern, driven by a central vertical shaft.
1984 Times 31 Oct. 19/5 (advt.) Traditional systems have always remained doggedly faithful to the bulky method of elevators and plansifters. Roncaglia has now put that all behind us and has managed to outdate the most up-to-date technology with air-current flour milling.
1993 Food Engin. Internat. (Nexis) June 30 The combination of commercial and technological advantages was the driving force behind the new development, which has allowed many mills to increase capacities by as much as 30% without requiring the installation of additional plansifters.
