OBJECT OF THE INVENTION
[0001] The present invention relates to the field of generating at least partially crystalline
textured surfaces.
[0002] The object of the invention is a device that allows the deposition of a layer of
ice or frost on the outer / inner surface of a container.
BACKGROUND OF THE INVENTION
[0003] Frosting is known in the presentation and preparation of containers as a technique
for the generation of a thin layer of ice or frost on the surface thereof.
[0004] Such operations are commonly used in catering in which containers such as bottles
are usually sprayed with water, then placing the bottles in a freezer so that the
liquid layer which coats the outer bottle surface, upon coming into contact with a
very low temperature, close to or beyond water solidification temperature, change
its state whereby the layer of water becomes a thin layer of ice, generally uneven,
namely frost.
[0005] This process is carried out manually and said change of state from water to frost
takes a long time.
[0006] A solution to this problem appeared in the form of machines and methods that use
various types of gases, having cryogenic characteristics and further not affecting
humans as they are not harmful; this is an important issue given the destination of
the container once the frost layer is applied on the outside.
[0007] Such machines and methods have an obvious disadvantage, due to the indiscriminate
and uncontrolled use of the application of gas and water, so that both are wasted
and in addition the production time of said layer of frost is increased.
DESCRIPTION OF THE INVENTION
[0008] To solve the above stated problem the device described herein is proposed, allowing
for the deposition of a layer of ice or frost on the outer surface, inner surface
or both of the container more efficiently.
[0009] For this purpose, the device described herein has a gas diffuser having a given gas
nozzle whose configuration allows the generation of a more uniform frost of the containers
to be frosted and in less time; also the coating process is carried out with a lower
percentage of gas, about 40% less in the case of using CO2 since the nozzle has a
series of conduits designed and arranged so as to achieve this more efficient result.
[0010] Likewise the device described herein makes use of a water diffuser having characteristics
defined by a specific nozzle for spraying the water more efficiently; for this purpose,
said nozzle is used having two joined holes at its end, thereby preventing the nozzle
from clogging or from freezing decreasing its spraying capacity.

PREFERRED EMBODIMENT OF THE INVENTION
[0012] In view of the figures, a preferred embodiment of the device (1) which is shown in
Figure 1 to produce a coating on a container (2) is described below.
[0013] For this purpose, the device (1) is connected, as detailed in Figure 2, to a supply
module (10) as a power supply or is equipped with a battery to enable its operation,
and both gas supply means (11) and water supply means (12).
[0014] Subsequently, the container (2) is introduced into a receptacle (3) of the device
(1) which in turn comprises at least one compartment (4) intended to at least partially
house the container (2), which is subjected to the action of a gas diffuser having
at least one gas nozzle (7), a water diffuser with at least one water nozzle (5) and
a control unit (6) which monitors the diffusers so that spray control means can be
implemented by means of solenoid valves connected to said control unit (6), such that
a first solenoid valve (13) connected to the gas diffuser and intended to control
the flow of gas into said gas diffuser and / or a second solenoid valve (14) connected
to the water diffuser and intended to control the flow of water into said water diffuser
and its corresponding nozzles (5,7).
[0015] Upon operation of the gas supply means (11), the gas, preferably CO2, flows to the
gas nozzle (7) shown in longitudinal section in Figure 4b. The gas is preferably pressurized;
said pressurization can be carried out by the very gas supply means (11). Once the
gas reaches the gas nozzle (7), it enters an essentially solid body (71) with a central
blind bore within it through which the gas passes until exiting through two threads
(72) which are two cuts 0.35mm in width defined forming 45° with respect to a central
longitudinal axis of the body (71) on both sides of a lower section of the body (71)
and connecting the outside of the body (71) with the centre bore as shown in Figure
4a, in a preferred embodiment the gas also finds an outlet in the lower part of the
body (71), as there is additionally a transverse groove of approximately 0.4mm which
connects the outside of the body (71) with the central blind bore inside the body
(71) allowing the exit of gas passing through the blind bore to the exterior. Thus
it follows that the gas exits through the sides of the body (71) of the gas nozzle
(7) and through the lower part thereof.
[0016] The gas supply is coordinated with a water supply being delivered from the water
supply means (12); by acting on said water supply means (12), water at a given pressure
preferably controlled via said water supply means (12) reaches the water diffuser
and the water nozzle (5) where, in view of figures 3a, 3b, 3c and 3d , it is noted
that the water enters a block (50) inside which at least two channels (51)are defined,
being respectively arranged at an angle relative to a central longitudinal axis of
the block (50) starting from an upper part thereof and converging at a point of the
lower part of the block (50), channels through which water flows until exiting the
block (50) of the water nozzle (5). This is the simplest embodiment thereof, however
in a preferred embodiment of the invention wherein it is possible to optimize the
coating generation operation described above, the water nozzle (5) has at least one
hole (52) defined at the top of the block (50) connecting at least one channel (51)
with the exterior of the block (50) such that water goes into said hole (52) before
reaching the channels (51); channels (51) that meet at an inner point of the lower
part of the body (50), a point from which in a possible embodiment of the invention
an orifice (53) originates that reaches the exterior of the body (50), while in an
alternative embodiment the channels (51) meet at a point of the body (50) connecting
the exterior of the body (50) allowing a channel (51) outlet at their intersection.
[0017] Water may exit from the channel intersection to the exterior as in a possible preferred
embodiment, both channels (51) intersect in an overlapping manner such that the intersection
of the two channels (51) have a section in common with that of one of channels (51),
i.e. two water flows coming respectively from each of the channels (51) converge at
an outlet point whose dimensions are equal to those of one of said channels (51);
another possibility is that the outlet point has other dimensions.
