DESCRIPTION

Procedure for operating a beverage dispenser and beverage dispenser

The invention relates to a method for operating a beverage dispenser according to claim 1, as well as to a beverage dispenser for performing the method according to claim 7. The beverage dispensers are mainly used in gastronomy and collective catering service. . Generally, beverage concentrates are supplied in beverage storage tanks that are then introduced into the beverage dispenser, which especially has a cooling function for the beverage that is in the beverage reservation tank. Before placing the beverage reserve tank or once introduced into the beverage dispenser, the beverage concentrate is diluted with water. The dispensing preferably takes place manually through an outlet system of the beverage dispenser.

For example, DE 10 2011 050 350 A1 proposes a beverage dispenser with a reserve reservoir for a beverage, especially a juice-based beverage or a mixed juice-based beverage that is essentially introduced into a closed housing. The beverage reservation deposit is made in the form of a removable element. The removable element is inserted into a housing deposit of the housing and has an outlet system for dispensing the beverage that is inside the beverage storage tank as necessary. The tank housing is made to be closed and is provided with cooling surfaces except for the housing opening. If the beverage to be dispensed is a mixed juice-based beverage, the beverage reservoir can be fed with water through a reservoir opening and a fresh water inlet connected to it. To do this, a water conduit flows into the reservoir housing. The tank opening is generally provided at the top of the beverage reserve tank, above the maximum filling height. The water conduit flows into the introduced state of the beverage reservoir through the reservoir opening.

According to DE 10 2011 050 350 A1, the removable element is completely open upwards. The removable element completely closes the housing opening in the state introduced in the anterior zone, thanks to which also the beverage is stored insulated in the housing.

Since the beverage reservoir is closed in the housing in a state introduced during operation and can be easily removed for cleaning, the hygiene standard is relatively high. However, precisely in the case of a long storage period, there is a danger that germs and dirt particles will enter the beverage tank through the air. In addition, control mechanisms are lacking, with the help of which it could be determined when and to what extent the deposit was cleaned. Therefore, it is practically impossible to avoid the lack of care or careless even conscious of hygiene by the operator of the beverage dispenser.

From JP 2006 341915 A a beverage dispenser for dispensing drinking water is also known, which has a cylindrical beverage reservoir, which is placed on a housing and has a beverage dispensing opening in the lower area. When dispensing beverage, the reservoir is subjected to depression and then ozone is introduced above the maximum filling level.

A beverage dispenser of this type is known from US 2010/0203207 A1. This beverage dispenser comprises a housing, a beverage storage tank in the form of a removable element, a housing opening, a storage housing for introducing the beverage reservation tank into the housing through the housing opening, a dispensing system, a dispensing opening made in the beverage reservoir that interacts with the dispensing system and a reservoir opening above the maximum filling height. In addition, a compression mechanism is provided that brings a surface of the beverage reservoir reservoir that encompasses the opening of the reservoir to a tight contact position with the corresponding wall of the reservoir housing of the housing.

The object of the invention is to improve a method for operating a beverage dispenser of the type mentioned at the beginning so as to eliminate the aforementioned disadvantages and the procedure largely excludes contamination of the stored beverage. In addition, a beverage dispenser is indicated to perform the procedure.

The task is solved by the main features of claim 1 in combination with the features of the preamble.

The invention is based on the fact that through the depression in the beverage reserve tank, contamination caused by the air in the beverage reserve tank can be avoided easily and from the beginning.

For this reason, according to the invention, a beverage dispenser is used which has a housing, at least one housing opening and at least one beverage storage tank in the form of a removable element with a

tank opening above the maximum filling height of the beverage reservoir. In the entered state, the beverage reservoir closes the opening of the housing. In addition, at least one reservoir housing is provided in the housing, into which the beverage reservoir is introduced through the housing opening. The beverage dispenser further comprises an outlet system and a dispensing opening that interacts with the dispensing system of the beverage reservoir. According to the invention, a compression mechanism is provided, through which the beverage reservoir is brought to a tight contact position with the housing housing of the housing. According to the invention, after the introduction and blocking, the reservoir of beverage reservoir is subjected to depression, especially under vacuum. This has the advantage that during the exclusive storage period the penetration of germs and particles of dust or dirt into the apparatus is avoided.

It is advantageous that when the dispensing system is opened, gas, especially air, is fed to the beverage reservoir. In this way, the amount of beverage dispensed through the amount of air fed, and the rate of dispensing beverage through the rate of air feeding, can be controlled on the one hand. On the other hand, the danger of contamination of the content during dispensing can be reduced, for example, through the configuration of the air supply means or by placing a suitable filtration device.

According to one aspect of the invention, data referring to the contents of the beverage reservoir are read or entered, which determines whether a dispensing is possible through the dispensing system and, if necessary, blocking the dispensing system. This solution offers several possibilities to prevent manipulation of the dispenser. In this way, an authorized user can directly determine the maximum dispensing period of the beverage or read the related data, for example, of a barcode on the beverage container, with a scanner.

Preferably, data is entered through a data entry means that interacts with a control unit: the amount of water that must be fed in relation to a product (concentrate) that is in the beverage reservoir, time of introduction in the reservoir of reserve of drink and / or specific data of the product like durability, temperature of necessary refrigeration or necessary revolutions of a device agitador. In this way it is possible to automate the entire storage and dispensing process from the introduction of the product until the end of the dispensing period.

In a further advantageous embodiment of the invention, the control unit controls the pump to block the dispensing of beverage generating a depression in the tank. In this way it is possible to easily avoid the dispensing of beverage through the control unit, without an additional mechanical locking device, if the end of the durability period has been reached or if, for example, as described below, Detects an attempt to manipulate.

According to a preferred embodiment, a control unit controls the pump and a valve, to block or authorize the beverage dispensing, through the measurement data recorded by a first sensor to determine the amount of water fed to the reservoir reservoir. of beverage and a second sensor to determine the level of filling in the beverage reservoir, and through the data entered and / or data stored in the control unit. This allows to detect technical difficulties or attempts of manipulation. Especially if a fruit juice concentrate is used and from the data entered or stored in the control unit it is known what product it is and how much should be found in a new warehouse, a comparison of the data determined by the first and The second sensor in relation to the water fed and the final filling level allows to determine if the correct filling quantity is in the tank. If this is the case, the dispensing of beverage is authorized. If the actual filling amount differs from the calculated filling amount, then there is a technical problem, for example, in the supply of fresh water, or an attempt was made, for example, to use a stockpile of manually filled and non-filled beverage reservoir. as planned, by the manufacturer. Since this does not correspond to the high hygiene requirements provided for the present device and the present procedure, in the latter case the dispensing of beverage is blocked. Through a readable manufacturer code of the product contained in the beverage reservation deposit, the use of the beverage dispenser can be limited, for example, to exclude competing products.

According to another aspect of the invention, a beverage dispenser is indicated for dispensing a beverage, comprising a housing, at least one beverage storage tank in the form of a removable element, at least one housing opening, at least one housing of reservoir to introduce the beverage reservoir into the housing through the housing opening. In this case, the beverage reserve reservoir is provided with a reservoir opening above the maximum filling level of the beverage reserve reservoir, a compression mechanism being provided, through which a surface of the beverage reservoir reservoir spanning the opening of the tank is brought to a tight contact position with the corresponding wall of the housing housing of the housing. This beverage dispenser is suitable for carrying out the process according to the invention, in which the beverage reservoir can be easily introduced into the beverage dispenser by means of a ramp, so that, preferably, it is sealed tightly, which It allows you to easily avoid contamination from the outside and generate a depression in the beverage storage tank. From

This results in other possible configurations to further reduce the likelihood of germ contamination, as shown below. In this case, the compression mechanism has a guide that runs in the reservoir housing from the reservoir opening in the direction of introduction of the beverage reservoir and has an ascending slope so that, in the introduced state, the guide in the Rear area holds the beverage reservation deposit against the top of the deposit housing.

The compression mechanism also has a ramp that is integrated in the beverage reservoir in the anterior area and is made so that the reservoir is fixed against the upper part of the reservoir housing when fully inserted, so that, in When it has been inserted, the reservoir of beverage reservation is supported on the guide in the rear area and on the ramp in the previous area. Due to this configuration, the compression only requires an effort hardly greater than that necessary to introduce the reservoir into a housing without compression mechanism, since the reservoir is introduced by the user essentially horizontally into the reservoir housing and, even in In case of a reduced angle of inclination, a sufficient compression effect is achieved.

In this case, the ramp is an integral component of the beverage reserve deposit. In addition, a gasket and at least one pump are provided. The pump can in this case be connected to the opening of the tank through a conduit, so that in the introduced state of the beverage reservoir and with the compression mechanism activated, the reservoir of beverage reservoir can be subjected to a depression through the pump The danger of contamination of the stored beverage is further reduced, since, on the one hand, the air in the reservoir before compression is largely removed and, on the other hand, depression reinforces the compression effect , which, in turn, results in better airtightness.

This has the advantage that, from the moment that the deposit with the beverage or at least part of the beverage is introduced into the housing, during the exclusive storage period the penetration of germs and particles of dust or dirt into the container is prevented. apparatus, mainly in the area of the tank opening. It is also advantageous that this sealing is possible without additional components, since an inner surface of the reservoir housing in the housing is used to cover the reservoir. This reduces manufacturing costs and simplifies cleaning.

Thanks to the fact that the surface of the beverage reserve tank that encompasses the opening of the tank is pressed against the top of the tank housing, indirectly by means of a gasket or directly, a maximum amount of storage is achieved in the tank.

Thanks to the fact that the compression mechanism is activated by the complete introduction of the beverage reserve tank, no additional elements or operation steps are required. The possibility of mishandling is excluded. The bottom of the tank can be chosen simultaneously so that it also presents, in a pressed state, a slight fall towards the carcass opening. In this way, the problem can be solved that, in the end, in the area at the bottom of the tank, a considerable residual amount of the beverage that cannot be extracted remains frequently. The outlet opening of the beverage reservoir is arranged, in this case, near the bottom, in the anterior zone. Since the bottom of the reservoir falls into the reservoir opening and, therefore, towards the outlet system, the residual beverage remaining towards the end of the dispensing process accumulates near the outlet system. In this way, a practically complete dispensing of the stored beverage without significant residual amounts is possible.

It is especially favorable if the guide is formed by the bottom of the deposit housing. This considerably simplifies the construction of the beverage dispenser and guarantees simple cleaning.

According to one aspect of the invention, there is a valve in the conduit which, when activating the pump, connects the reservoir of beverage reservoir to the pump and, when activating the dispensing system, to an air supply conduit. As a consequence, depression in the reservoir is briefly canceled during the dispensing of beverage as gas or air enters. The drink can be comfortably dispensed. Then the valve is switched again and the pump immediately generates a depression or vacuum. In this way, it continues to act against a contamination of the interior space of the tank.

It is especially favorable to have an air filter in the air supply duct, especially an activated carbon filter. In this way, the danger is minimized that with the gas, first of all the surrounding air that enters during the dispensing of the drink, germs or particles of dust or dirt reach the beverage reservoir and contaminate the beverage.

The air supply duct can also be used as a water inlet duct, which is necessary for the preparation of juice-based mixed drinks. A pump combined with the corresponding valve can transport air or water as needed. However, in an embodiment of the invention, a separate water conduit is provided for introducing the water into the beverage reservoir which, in the introduced state of the beverage reservoir, is connected to the reservoir opening or It flows into this. In this way, the beverage dispenser can be used not only to dispense ready-to-drink beverages, but

also for dispensing drinks that are prepared in the apparatus by mixing a concentrate of drink and water, guaranteeing hygiene and operating comfort through separate ducts for air and water.

For example, the water line can also be fed with water from drums or the like, whereby the use of the beverage dispenser is independent of local conditions.

Preferably, the water line is connected to a water pump that can be connected to a water tank, and water can be introduced from the water tank into the beverage reservoir. In this way, the beverage dispenser can be used independently of a water connection.

However, if tap water of sufficiently good quality is available, in the case of dispensing beverages from concentrates, the water line can be connected through a water connection to a fixed water connection. The beverage reserve deposit with the concentrate is introduced into the beverage dispenser, then water is added and the beverage can be dispensed. This reduces both the costs, as well as the need for space of the beverage dispenser, as well as the logistical effort.

According to another aspect of the invention, a valve is provided in the water conduit which, at its choice, creates a connection to the water pump or with a water inlet for manually fed water and for the connection of water for tap water. This allows the beverage dispenser to be used even more flexibly, since the type of water supply can be easily determined through the position of a valve.

In an advantageous configuration, the beverage dispenser has at least one data entry means that interacts with a control unit that controls the actuators of the beverage dispenser, such as the pump or the water inlet valve. It can be an introduction medium that requires active input via keys, a touch screen or the like or an introduction medium that reads information, such as a barcode scanner. In this way, the operator can comfortably enter the mixing, storage and dispensing parameters according to the needs. In a further advantageous embodiment of the invention, a first sensor connected to the control unit is provided, with which the amount of water fed to the beverage reservoir is measured. This information allows, on the one hand, to prevent the beverage reserve deposit from being filled beyond the desired measure and, on the other hand, to recognize an attempt at manipulation. This is explained in more detail below.

It is also favorable to use a second sensor connected to the control unit, with which the filling level of the beverage reservoir is measured. The information supplied by this sensor also serves to calculate the water input correctly, as well as to recognize attempts at manipulation.

To achieve protection, especially against tampering by unauthorized persons, the beverage dispenser may have a locking mechanism in the opening of the housing that ensures the reservoir of beverage reserve in the housing. This is reasonable, among other reasons, also from the point of view of hygiene, as this ensures that only authorized persons will have contact with the deposit and the beverage stored in it. The locking mechanism can interact with the control unit.

In addition, a cooling device is provided, which cools the interior space and, therefore, the beverage contained in the housing device. The cooling device is located under the housing device and comprises a compressor, a heat exchanger and one or more cooling surfaces arranged on the inner sides of the tank housing that interact with evaporators. Advantageously, the cooling device is also connected to the control unit. In this way, the desired temperature can be adjusted comfortably, if necessary, by the operator.

To guarantee a complete mixture, for example, of the components of a fruit and water juice and a uniform cooling of the drink, as well as to prevent the sedimentation of the pulp, etc. In unfiltered beverages, a stirrer is provided to mix the beverage during storage.

Preferably, a magnetic stirrer is used, in which a rotating and driven magnetic piece, which is generally provided in the housing under the beverage reservoir, moves to one side and the other at least one magnetic bar which is located in the drink. Advantageously, the magnetic bar (s) may already have been introduced together with the concentrate in a recessed area of the beverage storage tank. In such a device, the danger of contamination of the contents of the deposit is very small.

Other advantages, characteristics and possibilities of application of the present invention result from the following description, in combination with the embodiments shown in the figures.

In the description, in the claims and in the figures the terms used and the reference numbers assigned in the following list of reference numbers are used. The figures show:

Figure 3, a sectional view of the output system;

Figure 4, a perspective view of beverage dispenser, and

Figure 5, a block diagram to illustrate the development of the process for operating the beverage dispenser.

Figure 1 shows a beverage dispenser -10- in a sectional side view with a housing -12- and a beverage reservoir -14-. The beverage reserve tank -14- is introduced through a housing opening -13-, which is located on the front of the beverage dispenser -10-, in a tank housing -15-. To close the carcass opening -13-, a door -18- is also provided on the front, which can be folded down, with product lighting and filling level indication -20-. An electromechanical lock -22- provided above on the front of the beverage dispenser -10- serves to block the freely tilting end of the door -18- with the housing -12-.

The bottom surface of the reservoir housing -15- made as a guide -48- rises slightly from the housing opening -13- in the direction of introduction so that the upper side of the beverage reservoir reservoir having a reservoir opening - 17- moves slightly upwards when introducing the beverage reserve deposit -14- in the deposit housing -15- and, finally, when the beverage reservation deposit -14- is fully inserted, it is in contact in the back with the upper side of the reservoir housing. Additionally, the anterior area of the beverage reserve tank -14- oriented towards the housing opening -13- has a ramp -40- at the bottom. When the beverage reserve tank -14- is introduced, the ramp first passes through a projection -24- made inside the door -18- adjacent to the bottom of the housing opening -13-. The projection -24- serves to raise the area of the beverage reserve tank -14- showing towards the front side of the beverage dispenser -10- to facilitate the introduction. In a fully introduced state, the area facing the anterior side of the beverage reserve tank -14- is raised due to the ramp -40- which is supported on the bottom -19-, so that the reservoir opening -17 - It is also pressed in this area against the upper part of the tank housing -15-. The sealing effect resulting from this compression mechanism is further reinforced by a reservoir gasket -16- disposed on an upper edge of the beverage reservoir reservoir -14-.

At the bottom of the reservoir of beverage reserve -14- a recessed area -49- is provided in which at least one magnetic bar is placed which is moved by a stirrer -50- made as a magnetic stirrer to permanently mix the beverage.

On the inner sides of the reservoir housing -15-, the evaporators -56- form cooling surfaces through which the beverage reserve tank -14- and the beverage contained therein are cooled. Together with the evaporators -56-, a compressor -52- and a heat exchanger -54- form the cooling device of the beverage dispenser -10-. The evaporators -56-, the compressor and the heat exchanger -54- are connected to each other with the corresponding ducts. To reinforce the effect of the cooling device, an insulation -26- is also arranged around the reservoir housing -15-.

Next, the term "vacuum" is used in relation to the beverage dispenser and the procedure in relation to a condition, in general with components, such as pumps, ducts, etc. The term "vacuum" should be understood as a vacuum in the sense of a depression compared to the ambient pressure which can also be a low vacuum, from -300 to 1 hPa, medium vacuum, from 1 to 10-3hPa high vacuum (HV ), from 10-3 to 10-7hPa, ultra high vacuum (UHV), from 10-7 to 10-12hPa, ultra high extreme vacuum (XHV), <10-12hPa or ideal vacuum (IV). Depending on what is most economical in this context or the client's requirements, work is carried out in the corresponding depression ranges. The higher the depression, the lower the likelihood of contamination with germs through the waste gas in the beverage reservoir. In the case of a simple construction, the vacuum pump and the vacuum ducts should only be able to guarantee a depression compared to the ambient pressure in case of better quality embodiments, low vacuum or medium vacuum, etc.

Observed from the housing opening -13-, behind the reservoir housing -15- a vacuum pump -60- is provided by means of which a depression can be generated in the introduced state of the beverage reservoir -14- through a vacuum duct -64- which flows into the reservoir housing -15- to further strengthen the sealing effect described above.

Figure 2 represents a sectional side view of the beverage dispenser -10- in which the feeding of the beverage dispenser -10- with air and water is especially represented and in greater detail. As mentioned above, by means of the vacuum pump -60-, a depression can be generated through the vacuum line -64- which flows into the reservoir housing -15-. However, to dispense the drink, it is necessary to briefly eliminate this depression. To this end, a vacuum duct is connected to the vacuum pump -60-

air supply -66- through a valve -62- through which the air inlet is allowed. To prevent germs or dirt particles from reaching the beverage storage tank -14- and contaminating the beverage, an activated carbon filter -68- is provided in the air supply duct -66-. Through a control unit -80-, the vacuum pump -60- and the valve -62- are connected to a dispensing lever -30-. The activation of the dispensing lever -30- serves as a signal to briefly eliminate the depression by allowing air to enter, this being transmitted from the control unit -80- to the vacuum pump -60- and the valve -62-. After completing the dispensing process, the vacuum pump -60- and the valve -62- are operated by the control unit -80- so that a depression is generated in the beverage reservoir -14-.

In addition, the control unit -80- is connected to a water supply device that is intended for the supply of fresh water for mixing beverage concentrates in the beverage reserve tank -14-. The water supply device comprises a water conduit -74- which flows into the reservoir housing -15-. At choice, the water line -74- can be fed through a water connection -78- that can be connected to a fixed water connection and through a water inlet -72- that can be connected to a tank of water. To select the power supply, a valve -76- connected to the control device -80- is provided. Since, in the case of a feed from a water tank, unlike a fixed water connection, there is not always enough pressure in the conduit for the transport of water to the beverage reservoir -14-, the dispenser drinks -10- has a pressurized water pump -70- connected to the control device -80-.

Also connected to the control device -80- is a water flow sensor -82- provided in the water line -74- and a filling level sensor -84- provided in the tank housing -15-. With the help of these two sensors, the amount of water fed can be determined, as well as the actual filling level in the beverage reservoir -14-. The use of this data is explained below based on Figure 5.

Finally, a barcode reader -42- is provided to read the specific data of the product, but also a manufacturer code through a barcode on the beverage container. The barcode reader -42- is connected to the control device -80-, which allows to control the essential components of the beverage dispenser -10-, especially the vacuum pump -60-, the valve -62-, the valve -76-, the stirrer -50- and the electromechanical block -22-, based on the specific product data. The control is explained in detail based on Figure 5.

Figure 3 shows a sectional view of the output system. To dispense the stored beverage, a dispensing lever with hollow interior is provided which, in the closed state of the beverage dispenser -10- and with the beverage reserve tank -14- inserted, penetrates partly into the beverage reserve tank -14-. The dispensing lever -30- has on the side of the tank an outlet opening -32- and a closure -46-, the closure -46- being surrounded by a joint -34-.

In the pressed state of the dispensing lever -30-, the beverage penetrates through the outlet opening -32- into the dispensing lever -30- and, finally, arrives through a dispensing tap -28- to a drinking container or similar, not shown for clarity. An activator -36- provided in the lower part of the dispensing lever -30- is arranged so that in the depressed state of the dispensing lever -30- it is located above a switch -38-. In this position, activator -36- activates switch -38- during dispensing. The switch -38- is connected to the control device -80-. By means of the vacuum pump -60- and through the control device -80-, an activated switch signal -38- induces the elimination of depression during dispensing, facilitating the dispensing of beverage.

In figure 4, the beverage dispenser is represented in perspective with the door -18- closed. Above the barcode reader -42-, there is a screen -44- to show relevant operation data, such as the temperature of the stored beverage or the end of the dispensing period.

In the upper part of the housing -12-, a closure -46- is arranged to mechanically close the door -18-. Under the dispensing lever -30- a drip tray -25- is provided on which a drinking container can be supported while the drink is dispensed. In addition, the drip tray -25- is suitable for accommodating small amounts of beverage that can be tipped during dispensing or dripping between the dispensing processes.

In figure 5, a preferred method for operating the beverage dispenser -10- is schematically represented. After the start -100- the introduction -102- of the beverage reservation deposit -14- is made in the deposit housing -15-. Next, the entry -104- of an access code through a keypad field not shown is carried out to achieve greater clarity that must be confirmed in a verification step -106- by the control unit -80-. If the access code has not been entered correctly, a request for a new introduction -104- takes place. It is possible either to repeat the steps -104- and -106- until the correct access code is entered, or the lock -126- of the beverage dispenser -10- after a previously determined number of wrong entries -104-. As soon as the access code has been verified, the reading -108- of the specific product data included in the product package through the code reader takes place

of bars -42-. If necessary, a request can be displayed on the screen -44-. Based on the data read, a verification -110- of the durability is performed first. If it is found that the product to be dispensed, is no longer within the durability period, the control unit -80- induces the blockage -126- of the dispensing. This can take place, for example, by generating and maintaining a depression in the reservoir of beverage reserve through the vacuum pump -60-, which avoids dispensing of beverage. Thus ends -128- the process.

After the verification of the durability a differentiation -112 is carried out, which determines whether the product to be dispensed is a beverage concentrate or a ready-to-drink beverage. In the case of a beverage concentrate, the addition -114- of the amount of water required takes place. Then a determination -116- of the amount of the contents of the tank is made with the help of the data determined by the filling level sensor -84-. A verification -118- now takes place to determine if the amount of the contents of the deposit matches the nominal amount. The data on the nominal quantity are contained in the specific product data, which were previously read and, in case a beverage concentrate has been mixed with water, they are complemented with the data determined by the water flow sensor -82 - through the amount of water fed. If the amount actually present in the beverage reserve deposit -14- differs from the stored data or the calculated nominal amount, the result of the verification -118- is negative and it is concluded that either a technical problem exists, or produced an attempt of manipulation. A blockage -126- occurs immediately, as described above. Thus ends -128- the process. Finally, at intervals determined by the user or, ideally, according to the intervals indicated in the data read, specific to the product, a measurement -120- of the temperature is made in the reservoir of beverage reserve -14-. Temperatures that exceed a previously determined tolerance threshold are stored in the control unit -80- and can be consulted on the screen -44-, for example, after entering an access code. If temperatures too high are measured multiple times, the control unit -80- calculates -121-, in addition, a new maximum dispensing period for the beverage based on parameters taken from the specific product data and induces, for example, the indication of a warning signal on the display -44-.

Otherwise, the authorization -122- of the dispensation is produced. In each dispensing process, the control unit -80- performs a -124 check to determine if the dispensing period indicated in the specific product data is still met. If this is the case, a new authorization -122- of the dispensation is produced. If the dispensing period has been exceeded and the verification result -124- is negative, the control unit -80- induces the blockage -126- of the dispensing. Thus ends -128- the process.
