Period

C. 1900 to present

Canada

This flour-bolting machine was invented by Carl Haggenmacher of Hungary and manufactured under patent in Canada by the Toronto-based Canadian firm of Greey.

Function

A plansifter was type of flour-bolting machine that scalped or screened coarse flour from fine, and graded or separated different grades of middlings from fine and dressed flour, combining all these functions in one machine (see Ref. 1). Plansifters separated milled wheat into middlings and flour.

Technical

The invention in 1887 of the plansifter revolutionized bolting methods in flour mills. The plansifter took up less space and required less power than several machines previously used for the same functions. The plansifter was the beginning of a trend away from revolving reels towards bolt machines with flat sieves moving with a rotary action (ref. 1).
