Description

Title: Discharge device

The invention relates to a discharge device which will find particular application for piercing a package containing a granular material, and emptying it, essentially by the phenomenon of gravity.

The invention is more particularly interested in emptying vacuum packaging for which the granular material is compacted due to the vacuum inside the packaging and the pressure difference between the internal pressure in the packaging , lower than atmospheric pressure, and the atmospheric pressure prevailing outside the packaging.

[0003] The invention also relates to a fermentation unit with a fermentation tank, comprising a discharge device according to the invention configured to allow the aseptic transfer of the granular material, from the vacuum packaging to the fermentation tank.

[0004] The invention also relates to equipment comprising a pouring device according to the invention and a shutter, as well as a method for disinfecting the pouring device using such equipment.

[0005] The invention also relates to a vacuum packaging specifically configured to cooperate with said discharge device.

The discharge device according to the present disclosure finds a particular application for ensuring the aseptic transfer of granular material contained in a vacuum package, and in particular the aseptic transfer of a dry yeast contained in a vacuum package to equipment, especially industrial, such as a fermentation tank.

Technical area

The present disclosure relates to the field of vacuum packaging for granular, dry material, such as dry powdered yeast, and technical solutions proposed for aseptically transferring the granular material contained in the packaging to a donated equipment. [0008] In the field of beer manufacture, very often at several stages during manufacture, it is necessary to add dry yeast. For example, such an addition is made for carrying out fermentation in a tank, very often after cooling a must obtained by filtration of a mixture of crushed cereal grains and water.

[0009] Dry, active yeast is conventionally contained in a vacuum package to protect it during storage from oxygen and moisture. This package is opened for manual discharge through a manhole in the fermentation tank. As far as possible, this operation must be carried out aseptically, otherwise germs, bacteria or fungi will be transferred into the tank, which would then develop during fermentation, degrading the organoleptic qualities of the drink. In order to avoid the transfer of germs inside the tank, prior to piercing the vacuum packaging, the tools (such as a pair of scissors) used to open the packaging are disinfected, or even the disinfection of the outer surfaces of the packaging.

[0010] Once the vacuum package is opened, the latter is simply returned by the operator to the right of the manhole, and for the yeast to flow into the fermentation tank on the wort.

[0011] According to the findings of the inventors, such a practice is not satisfactory, and for several reasons:

- The disinfection of tools (such as pairs of scissors) typically carried out with a flame, or even by the use of disinfectant solutions is tedious and the success of the operation depends mainly on the rigor of the operator during this operation,

- Manual dumping of the packaging over the manhole is very often a tedious operation, with a significant risk of a detrimental fall, for example of a fall of the packaging itself within the the tank, and above all,

- The opening of the manhole necessary for the discharge of the yeast is in itself a risk of aseptic rupture of the tank, in that it allows an entry of air not sterilized in large quantities in the tank, with a potential risk of bacteria and fungi suspended in the air entering the tank, liable to contaminate the must.

Prior art

[0012] It is known from the state of the art of devices suitable for piercing and then emptying a package with a view to a hygienized transfer of product, such as for example disclosed by document EP 1 201 598. The device disclosed by EP 1 201 598 is intended for emptying bags of liquids such as sauce or drink, and implicitly requires the implementation of a suction. This technical solution is ineffective and non-functional for emptying granular material from a vacuum package.

Also known, for example from document GB 719054, a device specially intended for emptying a granular material (such as fine powder ..) in a given quantity. This device comprises a piercing tool, in the form of an ogive which allows the wall of a container to be pierced, and until a shoulder provided at the base of the cone contacts the wall of the container. This drilling tool is hollow and has a side opening intended to be positioned entirely inside the container when the shoulder contacts the wall. This side opening allows material to be transferred inside the body of the piercing tool which flows down to the base of the bullet to an outlet opening. This device is designed to deliver a dose of material corresponding to the volume of the hollow part, at each tilting of the container.

In any event, and according to the findings of the inventors, this device taught by GB 719054 does not allow to pierce and empty completely and quickly the whole of a package, keeping it in a static position, and more especially when it comes to vacuum packaging.

summary

The present disclosure improves this situation by proposing a discharge device which will find particular application for piercing a vacuum packaging containing a granular material, and emptying it, essentially by the phenomenon of gravity. More particularly, the device finds a particular application for completely emptying the granular material of a vacuum packaging, quickly, in a static position of the packaging, namely without the need to tilt the packaging.

Description of the embodiments

The invention relates to a discharge device 1 suitable for piercing and emptying a granular material contained in a vacuum packaging P.

The granular material is preferably dry, for example a dry, active yeast intended for carrying out fermentation, for example for the manufacture of beer. This granular material is contained in a vacuum package. The material and the packaging are compacted due to the vacuum and the pressure difference between the internal pressure, lower than atmospheric pressure, and the external pressure, namely the pressure, atmospheric.

According to the preliminary tests carried out by the inventors, the discharge devices operating by piercing a package to empty liquids or a granular material in a conventional package (without vacuum) as known from the state of the art by example disclosed by GB 719054, are not satisfactory when it comes to emptying compacted granular material from a vacuum package. When these devices are used with such vacuum packaging, the granular material begins to empty before the flow dries up. These dispensing devices do not allow the granular contents of the packaging to be emptied quickly. Otherwise, the air required to empty the granular content flowing against the flow, can generate reflux causing loss of granular material, which escapes from the device at the hole.

The present disclosure, at least according to one embodiment, arose from the observation by the inventors that the discharge devices of the state of the art, when used to pierce and empty a vacuum packaging, generate during the flow of the material a depression which may tend to maintain a vacuum inside the packaging, a vacuum which opposes the flow of the granular material. On the other hand, and when the air required for emptying flows only against the grain of the granular material, this air can lead to reflux causing product loss.

At least according to one embodiment of the present disclosure, the inventors have responded to this problem by designing a discharge device ensuring the discharge of the granular material by simple gravity, by promoting the air inlets through the opening of piercing of the packaging, and while the discharge device is substantially maintained in a static position, and without risk of loss of product, even in the event of reflux.

Advantageously, such a device thus makes it possible to quickly and continuously empty all of the granular material contained in the vacuum packaging.

Also, and as illustrated in the figures by way of non-limiting example, the discharge device suitable for piercing and emptying a granular material contained in a vacuum packaging P, comprises:

- a tubular body 2, having a conduit 20 for the flow of the material, extending from an inlet mouth 21 positioned at the level of a first end of the tubular body to an outlet mouth 22 for the material granular, positioned at a second end of the tubular body 2,

- a drilling tool 3, hollow, having a distal end terminated in a point 30 and an enlarged base 31 at its proximal end, integral with the tubular body at the first end of the tubular body, the drilling tool having at least one lateral opening 32 along the length of the drilling tool, said opening side 32 extending the length of the drilling tool from the enlarged base 31 of the drilling tool, said side opening being configured to allow material to be discharged from the outside to the inside of the hollow part of the drilling tool 3, the hollow part of the enlarged base 31 of the drilling tool 3 being in communication with the inlet mouth 21 of the tubular body 2,

a shoulder 4 having a peripheral stopper function, formed by the first end of the tubular body 2 disposed around and the widened base 31 of the drilling tool, said shoulder 4 having a stopper function being configured to come in contact with the wall of the packaging to ensure the stopping of the dispensing device when said wall is pierced by the piercing tool in a position where said lateral opening 32 extends inside the packaging.

In general, it is noted that the axis A of the drilling tool and the axis of the duct 20 are preferably substantially coincident, the duct 20 extending vertically, the drilling tool when the latter is oriented vertically, the point 30 upwards.

In general, it is noted that the drilling tool can include several side openings 32, distributed around the axis A of the drilling tool and for example four in number, each opening extending along a angular sector, in particular less than 90 °.

Thus, and as illustrated in Figure 4, such a discharge device is used by piercing the wall of the packaging with the drilling tool and until the abutment of the shoulder 4 against the outer surface of the packaging. The discharge takes place when the device is held in a position where the axis of the drilling tool is substantially, vertical, the point 30 directed upwards; the granular material flows, from the package, through said lateral opening in the hollow of the drilling tool 3, through the inlet mouth 21, and to the outlet mouth 22 where the granular material escapes.

In order to take into account the vacuum in the packaging which may tend to prevent rapid emptying of the granular content, the discharge device 1 may include the following characteristics, at least according to one embodiment. Said shoulder 4 to stop function, configured to come into contact with the wall of the packaging ensuring the stop of the discharge device when said wall is pierced by the drilling tool 3, is notably in a position wherein said side opening 32 extends over a first portion of length L1 inside the package and over a second portion of length L2 outside the package where said side opening forms an air inlet.

Thus and in Figure 4, it is noted that each side opening penetrates into the packaging on the first part of length L1 of the side opening 32, where said side opening allows the entry of granular material into the hollow of the drilling tool, and extends over the second part of length L2, outside the packaging where it forms an air inlet.

As visible in Figure 4, and as shown by the arrows with a single line, the second portion of length L2 of the lateral opening provides a lateral air inlet, at the level of the first end of the tubular body 2, against the flow of granular material flowing by gravity, shown by a double arrow. This lateral air inlet is advantageously in addition to the possible air inlet which takes place axially from the outlet mouth 22 through the duct 20 of the tubular body.

For example, the L2 / L1 ratio can be between 0.05 and 0.25 such as 0.1.

The side air inlet (s) formed by said side opening 32, significantly increases the quantity of air entering the vacuum packaging, avoiding the creation of a vacuum caused by the flow of the granular material, which favors the flow of the material coming from the vacuum packaging: the flow is significantly better and allows the granular contents of the vacuum packaging to be quickly emptied, even when the dispensing device is kept static, the point towards the top.

It should be noted however that from time to time, the air circulating axially against the current of the granular material can cause reflux of granular material which escapes laterally through said (or each) lateral opening 32 on the second section of length L2, outside the packaging. The inventors have overcome this problem by allowing the return of granular material, by gravity, within the device.

Thus and according to this embodiment of the present disclosure, said shoulder is at a distance radially from the enlarged base 31 of the drilling tool, the device comprises a cup 5, shaped on the first end of the tubular body 2, arranged at the periphery around the drilling tool 3, in particular at 360 ° around the drilling tool 3. This cup 5 is positioned intermediate between said shoulder 4 and the widened base 31 of the drilling tool: The slope of the cup is advantageously inclined towards the drilling tool 3 and configured (when the drilling tool is oriented vertically, the point 30 of the drilling tool directed upwards), so as to return the material by gravity granular having escaped the hollow part of the drilling tool inside the hollow part, through the second part of length L2 of the lateral opening 32. The bowl 5 thus advantageously has the function of bringing back into the duct 20 gr material annular which escapes laterally through said lateral opening 32.

Finally, said discharge device is configured to ensure the continuous emptying of the contents of the vacuum packaging, when the discharge device is oriented vertically, the tip upwards, the granular material flowing by gravity at the through said lateral opening 32 via the inlet mouth 21 and up to the outlet mouth 22 by gravity, against the current of the air entering the packaging in particular via the axial air inlet formed via line 20, and optionally, where appropriate, via the side air inlet (s) via said side opening 32.

[0069] By way of non-limiting example:

- the height H of the drilling tool along the axis A, from the shoulder 4 to the point 30 may be between 25 mm and 40 mm, for example of the order of 30 mm to 40 mm,

- the diameter D of the enlarged base of the drilling tool can be between 15 mm and 25 mm such as for example 20 mm,

- The diameter De of the cup 5 is between 120% and 200% of the diameter of the enlarged base 31 of the drilling tool, for example between 40 mm and 60 mm. According to an embodiment illustrated by way of example, in Figure 2, the enlarged base of the drilling tool having an outer radius R1 relative to an axis A of the drilling tool, the lower part of the bowl 5 having, in line with said lateral opening 32, a recess 50, in excess of the wall of the bowl 5 communicating with the pipe 20 of the tubular body 2.

This recess 50 is in particular configured so that the inlet mouth 21 extends radially outwardly beyond the radius R1 of the enlarged base 31 of the drilling tool, at least in line with said at least side opening 32.

Such a recess 50, in particular visible in Figure 2, further promotes the return of the granular material from the bowl 5 to the inlet mouth 21, avoiding the accumulation of material in the bowl 5, outside the drilling tool 3. Such a recess 50 can be provided to the right of each side opening 32. The inlet mouth 21 can thus extend to the right of the side opening 32 up to a radius R2 relative to the axis A of the 'drilling tool, greater than the outer radius R1 of the enlarged base 31 of the drilling tool 3, and as visible in Figure 2.

The drilling tool 3 may have the shape of an ogive, comprising ogive arcs 33 each extending from the enlarged base 31 of the drilling tool 3 to the tip 30 of the tool. drilling where the rib arcs 33 meet. Said at least one side opening 32 may include a plurality of side openings 32. Each side opening 32 preferably extends from the widened base 31 between two of the consecutive rib arches 33, over all or part of the length of the lattice. 'drilling tool in the direction of the point 30. By way of example, the ogive arcs 33 are four in number, distributed around the axis A, for example every 90 °.

According to one embodiment, the drilling tool 3 comprises a locking groove 34 intended to directly receive the edge of the wall of the packaging P or also indirectly via an annular ring B integral with the wall of the packaging. P. The locking groove 34 is configured so as to ensure that the drilling tool is held in place by the packaging once the packaging has been pierced by the drilling tool 3. For example and when the discharge device is configured as a hand tool, removable and independent, the locking groove 34 ensures the maintenance of the discharge device 1 to the wall of the package, suspended from the package , and without the need for the operator to hold back the discharge device 1.

As visible in the figures, the locking groove 34 is formed by a plurality of notches 35, for example on the ogive arcs 33, located on the same radius relative to the axis A of the tool. drilling. The notches 35 are positioned along the axis A of the drilling tool at the level of said shoulder 4 in the direction of the axis A, at a distance from the enlarged base 31 of the drilling tool in said direction of the axis A and so that said side opening 32 extends in height, when the wall of the package is blocked by the notches 35 of the locking groove 34, both, on the one hand, inside the 'packaging on said first part of length L1 of the drilling tool 3 located between the tip 30 and the locking groove 34, and on the other hand, outside the packaging on the second part of length L2 of the drilling tool 3 which extends between the locking groove 34 and the enlarged base 31. On this second portion of length L2, said lateral opening forms said lateral air inlet.

The locking groove makes it possible to cooperate directly with the edge of the wall of the packaging as illustrated in FIG. 4 or also indirectly via an annular ring B integral with the wall of the packaging, and as visible in FIG. 6 .

[0078] The invention also relates to a vacuum packaging P containing a granular material, as well as an annular ring B integral with the wall of the packaging, configured to come to be blocked in the stop groove 34 of a discharge device 1.

According to another possibility which can be combined (or not) with the presence of the annular ring B, the outer surface of the sealed wall of the vacuum packaging intended to be pierced, if necessary at the level of the ring annular B, is isolated from external contamination by a peelable sheet Pel, intended to be removed before drilling. This surface can preferably be aseptic or sterilized, just before the laying of the peelable sheet Pel. The variant of Figure 9 notably comprises a stop 37 projecting radially from the drilling tool (replacing the locking groove 34 of Figure 1), more particularly in the form of a ring, substantially perpendicular to the A axis of the drilling tool. This ring connects the rib arcs 33 of the drilling tool between them. This stop 37 is positioned substantially at the same level as said shoulder 4, in the direction of axis A, at a distance from the enlarged base 31 in this direction A. This stop is preceded by a screw thread, 38, which connects the rib arcs 33 of the drilling tool between them.

The installation of the discharge device is ensured by piercing the flexible wall of the packaging with the tip 31 of the drilling tool 3, then by screwing the screw thread 38 with the flexible wall of the packaging and until the flexible wall is clamped between the stopper-forming ring 37 and an immediately adjacent portion of the screw thread 38 when the wall of the packaging bears against said shoulder 4.

[0082] According to a first possibility, the tubular body 2 and drilling tool 3 assembly is configured as a hand tool, portable, manipulable by hand, configured to manually pierce and empty the granular material from a vacuum package.
