I, JOSE GUARDIOLA, of Chocola. in the Republic of Guatemala Central America'
Gentleman do hereby declare the nature of this invention to be as follows:-
My.improvements relate to evaporators for cane or other saccharine juices; and
the 'Invention. consists in the employment of a series of tanks or juice vessels
provided with steam, pipes and connected togetlier by juice pipes so that the
material can be, passed from one.tank to the other in the process of evaporation.
The tanks or juice vessels are placed side by side and set slightly inclined in
opposite directions alternately. They are of long and narrow form having ends of
less depth than the middle or body portion for gathering the scum raised in the .
process of evaporation and each tank having in its deeper portion a coil of steam
pipes connecting with a general steam supply pipe and general discharge pipe that..
connects to a steam trap or a condenser. The connection to the steain pipes of
each vessel.is valved so that the heat of each can be separately regulated and each
vessel thus forms an independent steam evaporator. In order to unite the series.
and form a continuous evaporator the separate tanks are connected by juice pipes
at their ends so that the tanks and the connecting pipes form a continuous channel
for the flow of the juice. The outlet pipe of each tank is provided with a disc
valve operated by a screw rod so that the flow of juice can be regulated and the
desired level inaintained or the flow cut off entirely when it is desired to reduce
the number of vessels in use and the capacity of the apparatus, or to work the
contents of either pan separately. In these cases connection to the vacuum pan
or other striking apparatus is to be made by uncoupling the outlet pipe of the last
pan and attaching it to a discharge pipe or a screw plug in the bend of the con-
necting pipe of that pan may be taken out and the juice drawn off at that point.
The tanks may be arranged in an upper and a lower series with a filler between to .
render the juice cleaner.
This evaporator will act rapidly and effectively from the fact that that the juice.
is divided into several portions instead of being in a large quantity with a compa-
ratively small heating surface. This effects not only a great saving in steam, but
the heat can be applied to any degree in either of the pans. The operation being
rapid the juice will not ferment so that there will be no loss of sugar from that
cause.
It will be readily seen that the tanks being of comparatively small.size can be -
easily transported and set up in any number according to the capacity .wanted.

Saccharine Juices.
I JOSE GUARDIOLA (Gentleman) of Chocola in the Republic of Guatemala
Central America do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained.
in and by the following statement :—
My improvements relate to evaporators for cane or other saccharine juices; and
the Invention consists in the employment of a series of tanks or juice vessels
provided with steam pipes and connected together by juice pipes, so that the
material can flow from one tank to the other in the process of evaporation, as
hereinafter more particularly specified and claimed. Reference is to be had to the
accompanying drawings forming a part of this Specification in which figure 1 is a
general plan view of an evaporator of my improved construction. Figure 2 is a
vertical longitudinal section and Figure. 3 is a transverse section of the same.
Figure 4 is a detail view. Similar letters of reference indicate corresponding parts-
in all the figures.
AA are the tanks or juice vessels placed side by side and at gradually lower
levels, the tanks being set slightly inclined in opposite directions alternately.
They are of long and narrow form having raised or shallow ends a for gathering
the scum raised in the process of evaporation, and each tank having in its deeper
portion a coil of steam pipes 6 connecting with a general steam supply pipe c and
general discharge pipe d that connects to a steam trap or a condenser. The con-
nection to the steam pipes of each vessel is valved at c¹ so that the heat of each
can be separately regulated, and each vessel thus forms an independent steam
evaporator. In order to unite the series, and form a continuous evaporator, the
separate tanks A are connected by juice pipes e at their ends so that the tanks and
the connecting pipes e form a continuous channel for the flow of the juice. The
outlet pipe e of each tank is provided with a disc valve f, see figure 4, operated by
a screw rod g, so that the flow of juice can be regulated and the desired level
maintained or the flow cut off entirely when it is desired to reduce the number of
vessels in use and the capacity of the apparatus or to work the contents of either
pan separately. In these cases, connection to the vacuum pan or other, striking
apparatus is to be made by uncoupling the outlet pipe of the last pan, and
attaching it to a discharge pipe, or the screw plug h in the bend of the pipe c of
that pan may be taken out and the juice drawn off at that point. The plug h also
allows for cleaning the pipes. The tanks may be arranged in an upper and a
lower series, with a filler between, to render the juice cleaner.
This evaporator will act rapidly and effectively from the fact that the juice is
divided into several portions instead of being in a large quantity wth a compara-
tively small heating surface. This effects not only a great saving in steam but the
heat can be applied to any degree in either of the pans. The operation being
rapid, the juice will not ferment, so that there will be no loss of sugar from that

page_text: cause.
It will be readily seen that the tanks, being of comparatively small size,
can be easily transported and set up in any number according to the capacity
wanted.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what
I claim is;-
In an evaporating apparatus, a series of tanks A having shallow or raised ends a,
steam coils between said ends, curved pipes e below and connecting the tanks as
shewn, diso valves f and their rods g regulating the flow of juice through said
pipes, substantially as set forth.
