Apparatus for heating and cooling worts in the process of fermentation.
[Wort is the fermentable infusion of malt. In the apparatus for heating and cooling worts, the hot liquor is passed through a series of pipes encased in others, through which the cold liquor passes in contrary direction: thus the hot liquor meets a progressively cooler medium, and, on the contrary, the cold liquor comes in contact with a hotter. The object is the saving of fuel. — W. D. L. R.]
