Harris' Patent Self-Acting Mashing Machine for the use of Brewers

1870 Scientific American  
This machine, after having been tried for a considerable length of time in one of the large�t breweries in this city with BUCCI'SS, and its merits thoroughly test�d, is claimed to be a grc'at improvement upon any other machine now ill use, and its construction to be founded upon a more scientific basis. From the porous strncture and absorbent nature of malt, all that is really requisite to produce complete saturation is to bring each snpara\,e crushed !!"rain or particle of grain into

It destroys the pores, beats the grain into a paste, and prevents the water frOllt flowit lg readily into and dissolving its soluble parts. Bdoroproeeelling, however, to duscribe this new invention it may he well to give a Rligh t sketch of the ui fferent means heretefore employed. Up to the present time there have been three methods of mashing, each method having various modifi cations. The originul COUl'Be was to mash by hand with oars (stout hars of wood Witll sundry cross pieces at the end). The great objec tion t,) this was t ' hat the cover necessarily being off the tub, the temperatnrc of the mash fell too low, rendering the ale produced from it liable to sour, besides the impossibility of properly stirring the contents of a large tub towards its cen ter. Machinery was then introduced to do the work while
