The
boilers, T, and engines, S, are of the common type of 20 horse power
nominal. The fans, L N, are the Farcot patent, illustrated a short time
since in our pages. The lower floors of the kilns are provided with
the Schlemmer patent mechanical turners. The turners, Fig. 4, in the
germinating cases are Saladin's patent.
[Illustration: FIG. 7.--ECHANGEUR, SECTIONAL PLAN.]
The germination of the grain is effected by means of cool moist air
provided by the fan described and the cooler and moistener--Figs. 5, 6,
and 7, herewith--known as an _echangeur_. As the germinating grain has
a depth of from 30 inches to 40 inches some pressure is required, and
mechanical means are necessary for efficient and economical turning.
The _echangeur_ is a very ingenious application of the well understood
rapidity of evaporation of any liquid when spread out in very thin
layers over large surfaces and exposed to a current of air. It consists
of a cylinder, or series of cylinders, of increasing diameter, placed
one within another.
