Combined separating, dressing, malt crushing machine.
This machine will thoroughly separate, dress, and evenly crush malt, however irregular in size the sample may be, without reducing any to powder, consequently obtaining an increased extract. An adjustable balance is affixed, showing both specific gravity and the extract obtainable per quarter.
A descriptive catalogue with prices, may be had of the patentee; and also manuscript instructions for brewing India pale ale as brewed at Burton-on-Trent.
