IMPROVEMENTS IN TANKS FOR COOLING YEAST
Year: 1884

page_text: I, JAMES WILLIAM JOHNSTON of 38 Carver Street, Sheffield in the County of
York Brewers Engineer do hereby declare the nature of my said invention for
IMPROVEMENTS IN TANKS FOR COOLING YEAST to be as follows:-
My invention relates to improvements in the construction of Tanks used for
cooling yeast, and has for its object the more rapid accomplishment of such cooling
operation.
In carrying out my invention, I use an outside tank preferably of wood and an
inside tank preferably of copper and having a waterspace between the two, both
round the four sides, and under the bottom of the inner tank.
I form this waterspace into a channel or channels preferably by means of wood
division plates or strips fitted between the two tanks in such a manner as to conduct
the cold water from the inlet, (which I prefer to place at the bottom of the outside
tank,) over the whole of the surface of the inside tank, before it escapes from the
outlet, near the top of the tank.
The channels may be arranged in returning convolutions, or in continuous coils
round the inner tank, but always in such a manner as to prevent the water
escaping in the shortest direction from the inlet to the overflow or outlet, and so to
utilise it to the greatest extent.

page_text: I, JAMES WILLIAM JOHNSTON of 38 Carver Street, Sheffield in the County of
York Brewers Engineer do hereby declare the nature of my invention for
IMPROVEMENTS IN TANKS FOR COOLING YEAST and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement, that is to say :—
•
My invention relates to improvements in the construction of Tanks used
for cooling yeast, and has for its object the more rapid accomplishment of such
cooling operation.
And in order that my Specification may be clearly understood I have annexed
hereto a sheet of drawings representing a Tank made according to my invention,
the same letters of reference indicate the same parts in any of the figures.
Fig. 1, is a plan or top view of a double tank, one shown with, and one without
the pan. Fig. 2, is a sectional elevation of same.
In carrying out my invention, I make a framework or outside tank, preferably of
wood, A, and provided with lids B, to fit over the tops of the tanks.
The pans or inner tanks C, are preferably made of Copper, but may be made of
any other suitable material, and when fitted in the outer framework A, a narrow
water space is left round the four sides, and also under the bottom, (that is, between
the wood and the copper) and this space is divided by narrow strips of wood D, or
other material if preferred, in such a manner as to construct a winding channel, or
channels E, so arranged that cold water entering at the inlet F, shall travel or flow
over the whole surface of the bottom, and four sides of the pan or tank C, before it
finally escapes at the outlet G, near the top of the tank.
The channel or channels E, may be arranged in returning convolutions, or in
continuous coils round the pan or tank, but always in such a manner, as to prevent
the water escaping in the shortest direction from the inlet to the outlet, so that it
may be utilized to the fullest extent, and fulfil the object of cooling the yeast, in
the pan or tank, and keeping it in a good and sound condition.
His an overflow pipe.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that.
what I claim is
The improved construction of tanks for cooling yeast with the arrangement of
winding channels for conducting water to all parts of the surface of the pan or
tank, for the purpose specified, and substantially as hereinbefore described and
illustrated.
