Examining the working bolter\n\nWe have a working bolter on the 2nd floor of the mill. This one in not original to the mill, it in fact pre-dates the mill, built likely in the late 1700s. We installed it here in 2010.\n\nWhile we rarely use it, it is a working bolter which was used to sift flour into various grades. In the early-mid 1800s, only fine flour ("superfine") could be legally exported. To get the fine flour a bolter was needed.
