Improvements in Apparatus for Treating, Preserving, and Improving
Foods and Food Substances:
We, ALBERT BAKER, of 80 Calhoun Street Fort Wayne, State of Indiana,
United States of America, Inventor and FRANK DELBERT BITTINGER, of Dayton,
Montgomery County, State of Ohio, United States of America, Doctor of
Medicine, 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 :-
Our invention relates to improvements in apparatus for treating, preserving and
improving foods and food substances, and is illustrated in the accompanying
drawings in which :-
Fig. 1 is a vertical half section of the main case taken through the line - of
Fig. 2. with the other half in perspective with part of the walls broken away to
show the interior.
Fig. 2 is a cross section of the main case through the lines o- of Fig. 1.
Fig. 3 is a vertical section of the main case taken through the line y-y of
Fig. 2. And
Fig. 4 is a cross section of the sub-interior cases and their envelope.
Our invention consists in the construction of a number of different elements
which may be combined in one apparatus. Various combinations of the different
parts may be used to accomplish specific results without the use of all parts, some
of which will hereafter be pointed out and others will readily occur to those skilled
in the art to which it appertains.
Several cases, vessels or chambers, are constructed and combined with each other,
which for the purpose of differentiation are named herein respectively as a main
case, a secondary case, and sub-interior cases. We also use throughout these
Specifications for brevity the word "current." By this term we mean a current of
air, water, gas, steam or any other suitable agent passing or forced through the
cases or chambers, which may be required in the particular process to which the
foods and other substances may be subjected. The selection of the agent or agents
will of course vary with the ideas and processes of the operator. And it will aid
in a better understanding of the use and scope of the invention to keep in mind
that these cases are not necessarily circular in form as shown in the drawings and
may be of such large dimensions as to constitute practically a fixed and permanent
apparatus. The complete invention is an apparatus consisting of the following
constructions.
We construct a main case of homogeneous material, or of different materials
hermetically joined together in any suitable manner. The construction of this case
of different materials is sometimes required when it is desired to coagulate the
contents in one part of the case without affecting the contents in the other part,
which may be done with some substances by making one part translucent and the
other opaque, where no external jacket or outside envelope is used. Or one part
may be of porous material permitting transference of elements or agencies contained
in the combination case, while the other or exposed part is dense material adapted
to protect from all outside influence.
A projection 24 is attached to the neck or opening of the main case provided
with an interior recess with a shoulder of sufficient depth to receive the rims of
enclosed cases and a plate or cover 10, and to leave a space or chamber 19 between
the plate 10 and a cover placed on top of the projection 24. We prefer to use also
with such projection 24 the cover and other hermetical sealing devices which are

page_text: fully described and form part of the subject matter of an application filed simul-
taneously herewith and such are shown in the drawings. A new use of this plate 10
and chamber 19 above it, is hereafter described.
We also construct a secondary case (2) of homogeneous material or of different
materials hermetically joined together for the same purpose for which such con-
struction is employed in the main case. We provide such case with a rim (46)
adapted to rest on the shoulder (26) in the interior recess (25) of the first pro-
jection (24), and extend the secondary case therefrom to, or near to the bottom of
the main case in which it is placed, the two cases being so adapted in size that
there shall be a chamber (17) between the walls of the two cases. We also provide
such secondary case (2) with a removable bottom (5) which is provided with an
orifice (44) which is closed by a plug or valve (45) in such manner as to resist the
pressure or passage of a current.
This orifice is for the purpose of providing a passage for a current into said case
without removing its bottom.
Over the rim (46) of the secondary case placed in the interior recess (25) of the
first projection (24), we also place a plate 10 adapted to form a cap or cover, and
we place suitable packing material between the rim and also between said plate and
the inner or first cover, adapted to seal the parts when the cover is secured in
place. In some cases the said plate may be secured in place, independently if
desired.
with a piston (6)
We also provide the secondary case (2) as shown in Fig.
adapted to move therein and be operated by the flow of a current preferably
through the orifice (44) in its removable bottom (5), or directly against it by
removing such bottom (5), thereby causing the piston (6) to be forced into the
secondary case (2) and compress the material therein which is sometimes very
desirable. By this means the contents of the secondary case may be held under
any pressure sufficiently to prevent the working and developement of spores and
bacteria. Such current may enter the case through the entrance pipes or through
any other opening provided therefor.
Between the secondary case (2) and the main case, see Figs. 1 and 2, we place
two or more partition walls (4) (where the cases are circular such walls are radial)
sub-dividing the space between them into two or more chambers or compart-
ments (16). The upper part of these walls are provided with projections or
arms (46) Fig. 1 on either side extended to and fitting against the walls of the
cases respectively. The lower ends are provided with like projections or arms (47)
extended on one side up to and fitting against the walls of the main case, and on
the other side extended underneath the bottom of the secondary case (2) and
providing a support therefor, and an aperture or passage way (48) underneath for
the flow of a current, which passage way is closed by a valve (13) preferably
wedge shape. Between these projections or arms these partition walls are made
narrower than the chamber (17) for the purpose of leaving passage ways or
apertures (49), for the flow of a current from one compartment into the other.
These apertures or passage ways are provided with valves (14) and means to
operate them from the outside of the cases. This is the preferable location of the
apertures provided with valves, but if desired they may be located elsewhere in the
partition walls. We operate these valves (14) preferably by connecting wires (50)
to the wide ends of the wedge shaped valves (14) at suitable places and conducting
them through the entrance pipe (51) and out of the sterilizer case (77). By
pulling such wires the valves are withdrawn sufficiently to permit the passage of a
current through the opening. Other wires (53) are attached to the sharp end of
said valves (14) and both are conducted outside the case, preferably through the
exit pipe (54) and sterilizer case, and afford means to close the valves. The
outside ends or handles attached thereto are enclosed with elastic or flexible
covers (83-84) hermetically attached permitting their operations without admitting
air to the case. The functions of these chambers and compartments and the openings
provided with valves are to provide a more uniform diffusion of a current and to

page_text: provide means to enable the operator to retard the flow from one chamber to
another at several different places, and to regulate its volume by the valves.
Another function is that the material in the different chambers may be subjected to
successive treatments by confining sterilized air or other agency in one chamber or
compartment until its action therein is completed, and then letting it flow into the
next chamber and so on.
In the chambers (16) formed by the partition wall where the construction is
very large for extensive operation, we further sub-divide the space by cross
walls (55) extended from one partition wall to the other. These cross walls may
be also, like the partition walls, provided with valves and openings if desired.
Within the compartments we place suitable supports for the materials, preferably
shelves (56) and brackets, (82) the brackets being adapted to support materials
suspended therefrom. By so suspending the foods and substances they are separated
from each other and thus better preserved in form and fibre, and provision is thus
made for free circulation around and through them of a current.
For extensive operation we also place preferably within the secondary case two
or more sub-interior cases (57) or chambers, seven of which are shown in the
drawings, Figure 4. we preferably enclose them within an envelope (58) adapted
to fit in the secondary case and be supported therein at any desired altitude.
These sub-interior cases are provided with covers (59) and means to hermetically
seal them, and also with removable bottoms (60) provided with valves or plugs.
These sub-interior cases when desired may be made with their envelope (58) of
the same size and length as the secondary case and when so constructed the
envelope (58) may be substituted for the secondary case, the function of each of
the sub-interior cases being identical with that of the secondary case herein before
described. Between these sub-interior cases (57), where they are constructed for
very large operations, openings or passage ways may be formed if desired, and in
such case they should be closed by covers or doors and provided with means for
sealing the same. In such case, the sub-interior cases should be rectangular in
form instead of being circular, as shown in the drawings. The function of these
sub-interior cases is to permit the operation of successive stages of treatment at the
same time so that when the material has been fully subjected to one step in the
process in one case, it may be removed to another case and submitted to a second
step in the process, fresh material being added at the same time to the first one and
other material taken out of the last one, and so continued.
Openings or passage ways between the interior cases and chambers and
compartments may be used if desired, for the purpose of transferring materials
and for communication, where the cases are made very large. Such openings if
used should be closed by covers or doors with means to hermetically seal the same.
We also provide an entrance pipe (51) and an exit pipe (54) to the main cases
Figs. 1 and 3 for the passage of a current, preferably extending them into the case
through its neck and covers. These pipes are provided on the outside with stop
cocks (61-62) to regulate the pressure of the flow of a current within the case; and
to permit the use of means io exhaust the air or gases from the case and its
compartments.
We also provide cells or recesses (63) within the walls of the apparatus at any
required places for the purpose of holding capsules (65) (which are used where a
better enclosure is required) and substances to affect the foods or contents. By
tilting the case the capsules may be dropped out of the cells into the foods. The
cells not containing capsules are provided with covers (64) adapted to be broken
or dissolved singly or in series by the application of heat, moisture, mechanical, or
chemical means at the will of the operator. The capsules (65) also contain
substances and are constructed of similar material. The materials of such cover
or capsule will vary largely with the character of the substances placed therein
and the means adapted for opening them. Some of the functions of the substances
placed in the cells and enclosed in the capsules may be to impart odor or flavor or
to restore a dissipated clement, and may be otherwise adapted to aid in the objects

page_text: stated according to the skill and choice of the operator, both in their selection and
times of operation.
We also provide a pipe (68) connecting the space or chamber (19) above the
plate covering the rims of the said inner cases and the entrance pipe. This is for
the purpose of creating a pressure by the flow of a current upon said plate to
equalize a like pressure upon the bottom of the secondary case.
We also construct a thermo-electric pile (15) or thermo-spiral consisting of
alternate plates or wires (69-70) of dissimilar metals, that is, of any two metals or
substances having different conductive power, such as copper and zinc, or bismuth
and antimony. We arrange such conductors alternately in series, connecting their
alternate ends so as to form a continuous path for an electric current to pass in
either direction. The ends of the series are attached to conductors (71) extending
to and connected with suitable sources of electric generation outside the case or
cases. Such current is regulated and controlled in the usual manner well known
to the art.
We increase or intensify the effect by providing enlarged surfaces or arms (72-73)
at such alternate points of contact by spreading such ends or points. These thermo-
electric piles (15) are preferably enclosed within the partition walls (4) and cross
walls (55). Their function is to produce that kind of heating and cooling action
known as the "Peltier and Thompson effects," described and illustrated in
S. P. Thompson's works and others.
Placing the thermo-pile within said walls is also novel and my own construction.
The purpose is to prevent short circuiting where the chambers or compartments
are filled with water, or contain other conducting fluid or material. Where thermo-
piles are placed in cross walls the ends of the plates project lineally beyond the
ends of the cross walls and are made so as to form points of attachment (74) to the
partition walls, sce dotted lines in Fig. 2 with dovetail in partition walls. They
are also placed so as to be near to but not in contact with the thermo-pile in the
partition walls.
This is a novel construction and is for the purpose of inten-
sifying the effects of such piles in the partition walls and in the vicinity of such
contact.
We also place upon suitable supports electric mats (9) consisting of fibrous or
porous material containing electric conductors arranged to form a path for an
electric current for heating purposes, and also constructed and arranged to produce
electrolytic action at given places, which latter effect is produced by arranging the
positive and negative ends of the wires to the opposite sides of the materials at
the given places, in such relation and manner, that moisture or other substances
are decomposed evaporated, collected or transferred by convection or electrolytic
action according to the particular arrangement of the wires and the nature and
desired treatment of the material. Such arrangements to produce such effects
are well known. Such mats are connected with conductors (75) extending outside
the case and attached to suitable sources of electric generation.
We also construct an electrical jacket enclosing the cases by interlacing through
a jacket (7) of porous or absorbent material enveloping the main case externally
electrical conductors (76) of different conductive power connecting the ends of the
series with any suitable source of electric generation, for the purpose of effecting
a heating and cooling action known as the "Peltier effect in contra-distinction.
to the "Joule effect." Such method has the advantage of being under exact
control.
"
We also provide an electrical sterilizer (52) and enclose it within the case (77)
which is placed between two sections of the entrance pipe, so as to form a section
thereof. The upper section (78) of the entrance pipe utilized as a conductor of
an electric current to a point separated from the lower section (79) of the pipe.
Between these points or sections of the pipe is attached an electrical conductor or
spiral (80) to both, of different conductive capacity from that below, or the section
below terminates in a point of different conductive capacity, the object being to
generate within the case electric heat and flame required for sterilizing. This may

page_text: be done as shown by the termination in the small spiral conductor (80) shown, or
in any usual manner: such as the use of carbons, terminal wires or resisting
incandescent mediums. This form allows the points of the conductors to come in
electrical contact, or otherwise, and like other common points they may be slightly
separated in any suitable manner so as to produce electrical heat and flame as
desired. Where a flame is required the separated points terminate in such materials
and are protected by devices well known, to protect the pipes from fusion. The
sterilizer case is filled with non-conducting material, so arranged as to, provide a
space through which a current of air or gas or other substance passes through an
electric area of heat or flame so generated, whereby the same is sterilized and may
be also ozonized when desired.
We also provide a cage (81) or receptacle in which we place antiseptic material,
and attach it to the entrance (51) and exit pipes (54) in such manner that all the
current entering or passing out through the inner ends of said pipes are passed
through and acted upon by the antiseptic material. We enclose the main case (1)
when used separately, with an outside envelope (8) hermetically sealed, for the
preservation and transportation. The operation of the apparatus above described
will readily occur to those skilled in the art from the description of the various
parts and the functions they perform.
