BACKGROUND OF THE INVENTION
[0001] The present invention relates to a horizontal press for squeezing essences.
[0002] More specifically, the present invention relates to a multiple-chamber horizontal
squeezing press which has been specifically designed for squeezing and/or producing
essences, both of an alcoholic and of an unalcoholic type.
[0003] Prior multiple chamber horizontal presses for squeezing a cocoa or oil seed mass
conventionally comprise a plurality of squeezing chambers for receiving therein the
material to be squeezed.
[0004] In particular, said squeezing chambers are made by coupling male elements, the so-called
counter-jars, and female elements, the so-called jars.
[0005] On the two sides of a counter-jar two disc elements, of an inter-exchangeable type,
and which are conventionally called "filter supporting plates" are arranged in order
to support thereon specially designed filters, which are conventionally called filtering
clothes.
[0006] The mentioned filtering clothes, during the squeezing operation are subjected to
a very high pressure thereby separating the liquid material from the solid material.
[0007] For making food products such as sweetmeats, pies, chocolat-cream cakes and the like,
the components thereof are conventionally mixed with a liquid perfumed by essences.
[0008] In order to set the perfumed material, a water, pure alcohol and essence mixture
or the like, in a paste form, is usually pressed to provide an alcoholic nature liquid
and/or an essence-perfumed liquid.
[0009] In this connection it should be pointed out that prior multiple chamber horizontal
presses are not suitable for optimally pressing the mentioned essences, since the
material to be pressed has properties and problems very different from those of a
cocoa liquor and an oil seed material being usually pressed.
SUMMARY OF THE INVENTION
[0010] Accordingly, the aim of the present invention is to provide a multiple chamber horizontal
press which is specifically designed for pressing and/or producing essences.
[0011] Within the scope of the above mentioned aim, a main object of the present invention
is to provide such a multiple-chamber horizontal press which is specifically suitable
for squeezing alcoholic essences.
[0012] According to one aspect of the present invention, the above mentioned aim and object,
as well as yet other objects, which will become more apparent hereinafter, are achieved
by a horizontal press for squeezing essences, comprising a plurality of squeezing
chambers, each of which comprises a jar and a counter-jar, wherein on each said counter-jar
two filter supporting plates are applied, characterized in that each of said filter
supporting plates is made of a stainless metal material, and that said filter supporting
plates are caused to contact one another during a squeezing operation.
[0013] According to a preferred embodiment of the present invention, the filtering clothes,
as assembled on the filter supporting plates, are made of a high strength magnetic
stainless steel material, whereas the material forming the filter supporting plates
comprises a high strength stainless steel.
[0014] According to a further preferred embodiment of the present invention, the inner liners
of the jars comprise a stainless steel material, differently from conventional prior
like presses, in which the inner liners of the jars are made of a conventional steel
material or are lacking since the squeezing chamber can merely comprise mating jar
and counter-jar elements.
[0015] According to another preferred embodiment of the present invention, the press is
processed on the outside whereof by an anti-rusting processing, in particular by a
nickel plating or teflon coating process.
[0016] According to a further preferred embodiment of the present invention, the jars and
counter-jars are protected by an anti-explosion bulkhead.
[0017] Finally, the press is driven by a pneumatic-hydraulic pump, provided with a pressurized
air driven pressure multiplier.
[0018] The invention provides the following advantages with respect to prior like presses.
[0019] At first, considering that the filtering clothes directly contacting the product
to be pressed are specifically designed for holding the dry and solid material for
causing the liquid part to be filtered out, said filtering clothes are made of a magnetic
high strength stainless steel.
[0020] This would allow to pick-up, by a magnetic detecting assembly, possible magnetic
particles susceptible to contaminate the product.
[0021] Moreover, the plates will operate to transfer the filtered moist or liquid part into
the counter-jar to be collected and outward ejected.
[0022] Thus, owing to the nature of the product being processed, the filter supporting plates,
as stated, are made of a high strength stainless steel material.
[0023] A further advantage of the present invention is that the filter supporting plates,
as assembled on the counter-jars, are specifically designed for contacting one another
during the squeezing operation, considering that the products to be pressed hold therein
a very high liquid material rate and, accordingly, the residue "panel" can have a
very small thickness.
[0024] Thus, an inner liner in a jar made of a stainless steel material will allow the inside
of the squeezing chamber to be properly protected from rusting, as a possible consequence
of water or moisture contained in the product being pressed.
[0025] Moreover, in order to prevent any rusting phenomena, susceptible to disadvantageously
spoil the product being processed, all the surfaces of the press are surface processed
in order to provide thereon an anti-rust coating, in particular by a nickel plating
or teflon coating method, or any other suitable rust protecting method.
[0026] The jars and counter-jars, moreover, are protected by an anti-explosion bulkhead,
to prevent a possible detachment of metal parts which could be caused by an accidental
exploding of the alcoholic substances being processed by the press.
[0027] In order to prevent any exploding risks, furthermore, the press is operated or driven
by a pneumatic-hydraulic pump, including a pressurized air driven pressure multiplier
therein, thereby allowing to omit any electrical motors susceptible to be arranged
near possibly exploding substances.

[0028] Further advantages and characteristics of the present invention will become more
apparent hereinafter from the following detailed disclosure, given by way of an illustrative
but not limitative example, with reference to the accompanying drawings, where:

essences according to the present invention;

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0029] In the following disclosure reference will be made to a preferred embodiment of the
present invention which has been illustrated as a not limitative example of several
possible variations of the invention.
[0030] Figure 1 shows a horizontal press according to the invention, which has been specifically
designed for pressing essences, and has been generally indicated by the reference
number 1.
[0031] The press 1 of the type comprising a plurality of squeezing chambers, each of which
includes a jar 8 and a counter-jar 7.
[0032] On each said counter-jar 7, two filter supporting plates 2 for assembling thereon
filtering clothes 4 have been arranged, the rear side 3 of each filter supporting
plate 2 being provided with a plurality of throughgoing holes 5.
[0033] Each said filter supporting plate 2 is made of a metal stainless material, in particular
a high strength stainless steel material.
[0034] Moreover, the filtering clothes 4, assembled on said filter supporting plates 2 are
also made of a high strength magnetic stainless steel material.
[0035] Finally, the inner liners 9 arranged inside the jars 8 are also made of stainless
steel.
[0036] The press 1 is processed on the outside surfaces thereof by any suitable anti-rusting
method, in particular by a nickel plating or teflon coating method.
[0037] As shown in Figure 1, the jars 8 and counter-jars 7 are protected by an anti-exploding
bulkhead 6.
[0038] Moreover, the press 1 is driven by a pneumatic-hydraulic pump, including a pressurized
air driven pressure multiplier.
[0039] In order to better understand the operation of the press 1, it should be pointed
out that the filter supporting plates 2 have been specifically designed to contact
one another during the squeezing operation.
[0040] Since, differently from a squeezing of a cocoa or oil seed mass, the products to
be squeezed herein are mainly constituted by materials holding therein a very high
rate of liquids, the residue panel provided thereby will have a very small thickness.
[0041] Thus, the filter supporting plates 2, mounted on the counter-jars 7, may contact
one another without damaging the press 1.
[0042] The presence of water in the product being squeezed or pressed, will require to form
the portions of the inner liners 9 of the jars 8 provided for contacting the product
starting from a stainless steel material.
[0043] Moreover, said water would require to surface process the press surfaces by a suitable
anti-rusting method.
[0044] As stated, the jars and counter-jars are protected by an anti-exploding bulkhead
in order to prevent any possible detachments of metal parts which would be caused
by an accidental exploding of alcoholic substances being processed by the press.
[0045] Moreover, in order to prevent any exploding phenomena from occurring, the press,
as mentioned, is driven by a pneumatic-hydraulic pump, including a pressurized air
driven pressure multiplier, thereby obviating any need of using electric motors near
possibly exploding substances.
[0046] From the above disclosure it should be apparent that the invention fully achieves
