Apparatus for Drying Macaroni.
I, WILHELM VATER, of Graben No. 11 Mannheim, in the Empire of Germany,
Manufacturer, 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 :-
The present invention has for its object an apparatus by means of which a
number of disadvantages are to be obviated that are experienced with the process
for drying macaroni now employed (and to some extent considered secret) and
the apparatus therein used. These disadvantages are that the macaroni is apt
to crack, warp and to become mouldy, and also to lose in taste and good light
colour.
A further advantage obtained with the new drying apparatus is, that the goods
can be put on straight surely and rapidly.
This apparatus, represented in the accompanying drawings, consists of a lower
and an upper part. The former is shown in plan in Fig. 1. In Fig. 2, it is shown
in cross section, and in Fig. 3 in longitudinal section. Figs. 4 to 6 show similar
views of the upper part.
The lower part as well as the upper consists of a sheet of metal u and o
respectively, each fixed on a wooden frame r r respectively and provided with
perforations placed close together.
The two long sides of the lower part u and the two short sides of the upper
part o are bent as shown at u' and o¹ the bend in each case being towards the free
side of the sheet of metal. The distance between the bent portions of the one part
determines the dimensions of the other.
Each of the two sheets is, at its inner side lined with cardboard or strawboard
of 1 millimeter to 1.5 millimeter thickness.
Between the sheet of metal and the wooden frame a strip of flannel is provided,
at the short sides of the lower part, u as shown at f and on the long sides of the
upper part as shown at f¹ the strip of flannel projecting about 8 millimeters as
shown in Fig. 7.
The macaroni to be dried is placed on the cardboard of the lower part the bent
portins u' serving to keep the pieces straight.
When the lower part is completely covered with macaroni, the upper part is
placed over it, cardboard-side downwards. The bent portions u¹ and o' respectively,
of the one part then take over the free edges of the other as seen in Fig. 8. The
flannel strip and f¹ between the two parts prevent access of air to the macaroni
from these points, whilst the cardboards between the metal sheets (u and o) and
the macaroni, prevent access of air in this direction.
The moisture contained in the macaroni put into the apparatus is absorbed by
the cardboard and thence, by evaporation, passes to the air playing around the
apparatus, through the perforations in the plates u and o.
Instead of the perforated sheets wire gauze stretched on angle iron frames may
be used in the apparatus above described.
Having now particularly described and ascertained the nature of my said inven-
ion and in what manner the same is to be performed 1 declare that what I
claim is.
An annaratus for drying mecezani without from cocase of air which annonatre is

page_text: characterized by two sheets of perforated metal or of wire gauze, u and o, the
inner surfaces of the sheets being lined with cardboard or strawboard, each having
bent portions u and o' respectively the one (a) on its long sides, the other (o) on
its short sides, so that the bent portions in conjunction with the packing strips f
and hermetically close the space between the plates or sheets, into which space
the macaroni is placed, so that the drying of the macaroni proceeds with the
exclusion of direct contact of air by absorption of the moisture into the cardboards
or strawboards and evaporation from the surface of the latter.
