pushels a day. The fruit is prepared 
in every detail the same as for drying 
in kilns. 
In the other method the racks are 
about 4 feet square and occupy the en- 
tire cross section of the tower instead 
of half the space, as in the method just 
described. The racks are admitted to 
the tower at the same point as in the 
other style, but as each rack is put in 
position it is raised by a lever attach- 
ment, together with the other racks 
which may have been already put in 
place, and held in the new position by 
dogs or clutches which work automatic- 
ally, allowing the racks to be moved up- 
ward, but not permitting them to move 
downward. The distance which the 
racks are raised each time the lever is 
moved is sufficient to allow another 
rack to be inserted below them at the 
usual point of admission. It will thus 
be seen that the racks are gradually 
raised from the point of insertion on the 
first floor to the point on the second 
floor where they are removed. The 
racks do not come into the view of the 
operator from the time they are insert- 
ed until they reach the place where 
they are removed, and so do not come 
under the same scrutiny of the opera- 
tor as in the other style. The arrange- 
ment of the furnaces is the same in both 
methods of construction. 
Miscellaneous Types of Evaporators 
While the types of evaporators previ- 
ously described admit of endless modifi- 
cation in the details of construction, and 
other types and styles of lesser impor- 
tance are frequently seen, there is but one 
additional evaporator to which it seems 
desirable to refer in this connection. The 
type in question has no particular desig- 
nating term applied to it. Several styles 
which possess some features similar to 
this one have been called “cabinet evapor- 
ators,” and this term is applicable in the 
present instance. While it appears to be 
largely of local reputation, it is believed 
to possess certain points of merit worthy 
of more extended application in construct- 
ing evaporators of considerable capacity.

ENCYCLOPEDIA OF PRACTICAL HORTICULTURE 
The fruit is dried on racks similar to 
those used in tower evaporators. 
In the first one of this type to be erect- 
ed, so far as the writer has been able to 
learn, and which is still in use, the com- 
partments in which the fruit is dried are 
located in the central part of a large room 
in which the fruit is sliced and handled 
after it is removed from the evaporator. 
Each compartment, of which there are 
three, is slightly more than eight feet 
square, or large enough in cross section 
to receive four racks (two square) on the 
same plane. The two opposite faces or 
sides of these compartments are a Series 
of narrow doors, about six inches wide 
and slightly more than four feet long, 
which extend horizontally. These doors 
are hinged on the lower side and held in 
place by a button at the top. The sides 
of the interior are supplied with cleats 
on which the racks rest. Two racks 
placed one directly on the other are ad- 
mitted at each door. In the particular 
case in question, there is sufficient space 
between the floor and ceiling of the room 
for eleven of these doors, each door ad- 
mitting, as stated, two racks. It will thus 
be seen that the capacity of each compart- 
ment is 88 racks. 
As arranged in this evaporator, the 
racks are admitted to the drying compart- 
ments on the same side of the room that 
the apples are sliced, the ones that are put 
in first being pushed to the opposite side 
of the compartment, thus making room 
for the second set of racks in the course. 
The attendant in charge of the drying 
makes his examinations and removes the 
fruit when dry through the doors on the 
opposite side of the compartment. 
It will thus be seen that the method of 
handling the fruit is similar to that em- 
ployed in the case of the tower driers, but 
the work is all done on a single floor of 
the evaporator. 
The heat is supplied by a system of 
steam pipes which extend in horizontal 
tiers through the compartments between 
the racks.
