Improved Method of Preserving Bread and other Articles of Food, and
Apparatus therefor.
I, MAX MARX, of Marktstrasse 124, Crefeld, in the Empire of Germany, 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:-
It is a great drawback for seafaring-men who have to pass a long time before
they can reach a harbour, and for soldiers in camp or when in fortresses during
war, and for hotel proprietors, on high mountains or in remote places, that they
have to live sometimes for considerable periods without bread, because they can
rarely get it fresh, and because it becomes uneatable after a comparatively short
time. The object of the present invention is to remove this drawback, and to
The invention
make it possible to be always in possession of good moist bread.
consists in a method of packing bread so that it remains for a long time fresh
and eatable, and may be described as follows, reference being had to the accom-
panying drawing in which Figures 1 and 2 are longitudinal and transverse sections
of the bread or like container, and Figure 3 a plan view of the grating or floor.
The fresh baked food, such as bread, a hot as it comes out of the oven, is
placed in a tin or other box b, which can be hermetically closed, and which is
slightly larger than the food to be preserved. As soon as it has been placed in
the box the latter is immediately closed hermetically. In consequence of the
great heat still contained within the food the germs in the air contained in the
vessel are destroyed. The steam evolved is condensed after cooling on the sides
of the tin, from which it collects at the bottom of the vessel. To prevent the bread
from coming in contact with the latter, and thereby losing its pleasant taste by con-
tact with the oxide forming at the bottom of the tin, a grating or floor c
provided at the bottom of the vessel, on the perforated rods of which the food
rests.
IS
When the bread or food begins to get dry, the water contained in the vessel
evaporates and passes back into the bread. The effect is therefore that the food
is preserved in a space filled with air free of germs and saturated with water. This
method of keeping is exceedingly simple and easy, and the food is preserved
exceedingly well. Even after the lapse of months it is still moist and fresh and
retains for the whole time its original taste, and even its aroma is preserved, which
when kept in the ordinary manner is lost after a few days.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A method of preserving bread or other food consisting in hermetically
enclosing the food in tins or the like, whilst in a hot state as it leaves the oven,
substantially as described.
2. A tin or container for packing bread or other food to be preserved provided

page_text: with means for hermetically closing same and with a grating or floor for the
purpose of preventing the food from coming in direct contact with the water
produced by the condensed steam from the hot food or with the oxide which may
be formed on the sides of the container substantially as described.
