page_text: I, FRANZ VYRAZIL, of 85 Wendische Gasse, Prague, Bohemin, in the Empire of
Austria, Engineer, do hereby declare the nature of this invention and in what manner
the same is to be performed to be particularly described and iscert uned in and by
the following statement
This invention relates to apparatus for use in evaporating, distilling or condensing,
the same being specially adapted for employment in the sugir industry
'
Apparatus constructed according to this invention is represented in longitudinal
section in Fig 1 and transverse section in Fig 2 of the accompanying drawings
Fig 3 being transverse section, to in enlarged scale through two of the evaporating
or condensing elements A number of evaporiting elements a are mounted butween
the ends of hollow drum or casing A B The litter serves to prevent undue loss of
heit by radiation from the evaporating elements, the external surfaces of which may
be heited by stem admitted for the purpose through the pipe S to the casing A B
The flow of steam within the casing may be regulated by micans of biffle-plates, such
is, whereby the same is caused to impinge primarily upon the lowest row of
evaporating elements, then upon the row next above, and so on with each row in
succession until the highest row is ultimately reached If proferied, however, tho
ste um may be admitted to the casing A B from the side or from the top, the course
followed by the same in heating the several rows of evaporating clements buing varied
Iccordingly Condensed water may be withdrawn from the casing A B through the
pipe s
The evaporating elements a ue arranged horizontally in rows
The Juice
Hows in the same direction through the several clements appertaining to each row and
in opposite directions through alternate rows Thus, the juice to be evaporated is
admitted through the pipe d to the chamber d' which communicates with the highest
row of clements From this chamber, the juice flows through the highest row of
Capo iting elements into the chamber d, and overflows thence to the chumbur d³
From this chamber the juice flows through the second row of ev sporiting clements to
the chumber d' ind over flows thence to the chamber d³ and so on, until eventually

page_text: the concentrated juice escapes from the lowest row of evaporating elements through
the pipe d* The apparatus is preferably constructed so that the steam-pipes ?
(hereinafter more particularly refurred to) may be always submerged bene ith the
juice whilst the process of evaporation or condensation is being carried out
This end
is easily attained by suitably regulating the position of the overflow passage leading
from one chamber to the next chamber beneath Provision is made for enabling the
Juice to be independently drawn off from any of the upper rows of evaporating
elements Instead of the juice flowing in the same direction through each of the
evaporiting elements constituting one horizontal row, it may be caused to flow in
opposite directions through adjacent elements in each such row, o1, it may be caused
to flow in one direction through two, three or more contiguous rows and in the opposite
direction through the next two, three or more contiguous rows The vapour evaporated
from the juice may be conducted through pipes & into a chimber K and there condensed
in the usual way Each of the evaporating elements a consists of a tube C, preferably
cylindrical, as shewn, the sud tube containing number of small steam-pipes
submerged beneath the surfice bc (Fig 3) of the juice or liquor to be evaporateu The
steam-pipes are carried by the outer wills DE ind G H of the drum or casing AB,
the joints being rendered water-tight, ind being by preference of such a chu icter as
Steam is admitted
to permit of the ready withdrawal when requisite of the tubus ?
through the pipe H into ich umber communicating with the steam-pipes appert uning
to the bottom row of evaporating clemonts The sto un, after flowing through the
ste um-pipes referred to arrives in a second chamber at the opposite end of the drum
or casing AB, this second chamber affording communication with the steim-pipes
appert uning to the next row of evaporiting elements The steam, after passing through
the latter, arrives in a third chamber situated above the first From the third
chimber, the steam passes through the steam-pipes in the third row of evaporating
elements into a fourth chamber, and so on, until it arrives in the list chummber, each
chimber, with the exception of the first and, in the present illustration of the last,
serving to communicate between two adjacent series of steam-pipes Condensed water
1s withdrawn through the pipe I
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is
-
1 The improved evaporating, distilling or condensing apparatus, constructed
and operating substantially is herein described
2 The combination of a series of evaporating elements a, eich with inner tubes r,
capable of being withdrawn therefrom, with a drum or casing enclosing the said
Felements-,-the-whole forming an-evaporating, distilling or condensing apparitus
3 The employment in an evaporating, distilling or condensing apparatus of
elements, such as a, arranged side by side in horizont il rows, the said rows being
disposed one above another, substantially as herein described
