Description
P34000NLO0O
FOOD PRODUCT DISPENSING SYSTEM The invention relates to a flowable food dispensing system which flowable food in embodiments is initially in a frozen state, a flowable food dispenser for dispensing said food product, a flexible pouch containing the flowable food product, and a method for using the flowable food dispensing system.
Various fresh and flowable food products such as juices, soups, sauces, cheese spreads, ketchups, dairy products, humus, pasta’s, smoothies, teas, extracts, and crèmes are considered tastier and/or more nutritious when they are consumed closer to the moment when they were made. For example, fresh orange juice is considered tastier than preserved orange juice. However, preparing such food products may be a time consuming and labour intensive process, therefore pre-made and often preserved versions of the food product may be preferred.
Flowable food products may be frozen at completion of production in order to preserve the food products for a longer time. However, the frozen food products then has to be melted prior to consumption. Melting of the frozen food product may be achieved by removing the food product from a freezer and waiting, passively melting the food product, or by heating the frozen food product, actively melting the food product. Passively melting the food product may take a long time and thus is not practical. A difficulty in actively melting frozen food products is that heating of the frozen food product may affect the taste and nutritional value of the food product. For example, a frozen juice which is heated during melting to too high temperatures changes taste. In order to preserve taste and nutritional values precise heating during melting is necessary. This is not only true for juices and smoothies but also for other frozen food products such as, beverages, cocktails, cheeses, sauces, soups and doughs.
US1940353 discloses a method for reducing frozen juices which method comprises the step of placing a block formed by a frozen food product in a heat zone of an apparatus and simultaneously comminuting the frozen liquid and subjecting the frozen liquid to heat for the purpose of causing liquefaction. The melted liquids are then removed from the heat zone to avoid materially raising their temperature.
A problem associated with the dispenser from US1940353 for flowable food products is residue of the food product which is left behind on the dispenser. Such residue should be removed to comply with health and safety regulations and to avoid negatively impacting the
2. taste of the food product. Additionally, residue may result in a less pleasing looking dispenser and cause contamination of the flowable food dispenser. This may negatively impact the taste of the food product and increase maintenance requirements of the system.
A further problem associated with dispensing flowable food products which are initially in a frozen state is that the food product has to be heated in a predictable manner to avoid heating the food product too much or too little and too slow.
It is an object of the invention to provide an alternative flowable food dispensing system for flowable food products, more in particular to provide an improved flowable food dispensing system for initially frozen food products. It is a further object of the invention to obviate one or more of the problems described hereinabove and in particular to provide a flowable food product dispenser which does not affect the taste of the food product and which, additionally, is not subject to residue left behind in the dispenser. It is yet a further object of the invention to provide a flowable food dispensing system that allows for a more efficient or practical use. The invention provides a flowable food product dispenser system according to claim 1. It will be appreciated that the invention is applicable to a wide variety of flowable food products, in particular advantageous for flowable products that have extended shelf life when frozen, e.g. immediate freezing upon production avoiding or reducing the need for treatments and/or additives that affect freshness, taste, appearance, etc. The flowable food product may for example be a beverage, such as a fruit juice, e.g. obtained from freshly pressed fruit. The flowable food product may also be a base ingredient for preparation of a smoothie, e.g. consisting of or comprising pureed fruit, etc. The flowable food product may also be a diary based product, e.g. a flowable cheese based product. The flowable food product may be a sauce. In general, the flowable food product can be any food product that flows when it is no longer frozen.
3. Preferably, the flowable food product in the flexible pouch is sized as a single portion for human consumption of the product. For example, the food product in the pouch has a volume between 0.1 and 0.5 litres.
In practical embodiments, the dispenser has a control unit linked to the drive mechanism of the two heating elements, wherein the control unit is configured, e.g. programmed, so that the heating elements are moved by the drive mechanism to the pouch flattening position in a dispensing cycle, so that the entire volume within the pouch is dispensed within one dispensing cycle. The flowable food product is initially in a frozen state, e.g. the food product being filled into the pouch and then being frozen, e.g. in view of shelf life. Before consumption, the flowable food product is to be melted by operation of the dispenser.
For a range of envisaged applications of the invention, e.g. for a fruit juice, a smoothie, etc., the melting has to be done in such a way that the dispensed product is cold. So for these applications it is envisaged not to heat the flowable food product to an elevated temperature. For other possible applications, e.g. for soup, bouillon, hot beverages, it is envisaged that the system is configured to heat the flowable food product to an elevated temperature, preferably directly ready for consumption as heated food product. For example, a freshly squeezed fruit juice could be preserved without the need for shelf-life enhancing treatment and/or additives to retain its qualities for a long time and after proper melting appear to be freshly squeezed. For example, a melted and cold food product will be dispensed from the pouch at a temperature between 6 degrees Celsius and 12 degrees Celsius.
For example, a heated food product will be dispensed from the pouch at a temperature above 25 degrees Celsius, e.g. above 35 or above 65 degrees Celsius. The flowable food dispensing system comprises a flowable food dispenser, which is configured to melt, possibly heat to an elevated temperature, and dispense the initially frozen food product.
-4- Preferably, the dispenser is placeable on a kitchen counter close to a freezer to allow rapid placement of the pouch with frozen food product from the freezer into the dispenser. The dispenser further, preferably, comprises a support for placing thereon a plate and/or a cup for receiving the flowable food product as it is dispensed. The flowable food product dispenser comprises two heating elements for melting the frozen food product and comprises a pouch receiving assembly. The heating elements are moveable relative to each other such that the heating surfaces of the heating elements may move towards each other.
The heating elements may be connected to a motorized spindle drive system to cause movement of the heating elements relative to one another.
In embodiments, each of the two heating elements is resiliently supported in the perpendicular direction, so the direction into which the heating elements are pressed onto the main surfaces of the pouch.
For example, one or more resilient members, e.g. springs, e.g. metal springs in view of the high temperature environment, are arranged between each of the two heating elements and a drive motor for each or for both heating elements. This resilient support enhances continuous contact between the heating surface of the heating elements and the main surfaces of the pouch, e.g. during continued advancing of the heating elements to the pouch flattening position upon melted flowable food product being discharged via the spout of the pouch.
So, as preferred, the heating elements are held in constant contact, e.g. via a resilient support, with the main pouch surfaces during heating and dispensing of the product. This resilient support allows to compensate for irregularities in the melting and flowing out of food product from each vertical side of the pouch.
The heating surfaces may be heated to a desired temperature depending on the type of food product. However, for melting and dispensing a cold, melted product it is equally possible to have the heating elements operate at a fixed temperature, with the duration of the dispensing cycle being variable, e.g. due to variation of the volume of food product in the pouch.
In embodiments, the heating elements are heated to between 90 and 99 degrees Celsius, e.g. between 95 and 99 degrees Celsius. In this approach the temperature is high, yet below
5. boiling point of water. This choice of range with a maximum of 99 degrees is preferred in view of the possibility of frozen mist on the outside of the pouch. When brought into contact with the hot heating elements, a temperature within the proposed range causes quick evaporation of such frozen mist, yet avoids boiling effects and any noise produced thereby.
Preferably, the dispenser is configured to start heating of the heating elements upon the receiving assembly being moved into the pouch heating position. Preferably, the heating elements are heated already ahead of the heating elements being pressed onto the pouch. Preferably, the heating elements are each made as a metal block, e.g. each having a rectangular shaped heating surface, with one or more electric resistors integrated with, e.g. embedded in, the metal block to cause the heating.
Preferably, a non-stick coating is applied to each of the heating surfaces, e.g. in view of cleaning. Preferably, the heating surfaces are flat surfaces, e.g. rectangular flat heating surfaces.
The heating elements may each comprise a temperature control system for controlling their temperature. The temperature control system may comprise an individual temperature sensor for each heating element, which measures the temperature of each heating element thus providing information to the control unit of the dispenser. For example, the control unit operates on the basis of a set-point for the temperature of each heating element, e.g. electric power being supplied to each heating element (e.g. including a resistor) to control the temperature. The control unit may be embodied to monitor electric current applied to the resistor type heating element, e.g. a determination being made on the basis thereof when the dispensing of food product has been completed. The control unit may increase or decrease power supplied to the heating elements based on the information provided by the temperature sensors.
The heating elements are placed opposite each other in the food product dispenser such that the heating surfaces face each other and are oriented substantially vertically. This allows a
-B- frozen flowable food product to be placed between the heating elements and, when it melts, to flow downwards away from the heating elements without coming into contact with the heating elements. This prevents contamination of the heating elements by the food product.
The heating elements are moveable between a pouch receiving position and a pouch flattening position. In the pouch flattening position the heating elements are located closer to each other than in the pouch receiving position.
Preferably, the heating elements are very close to each other in the pouch flattening position, e.g. the empty pouch being sandwiched between the surfaces, e.g. just the main chamber thereof with the spout sticking out below the heating elements.
The heating elements can be separated by a distance to allow a pouch to be received between the heating elements in the pouch receiving position. When dispensing cold, melted, food product continued movement between the pouch receiving position and the pouch flattening position causes the pouch to be in constant contact with the heating elements as the frozen flowable food product in the pouch is melted and directly dispensed.
Movement of the heating elements may be driven by a motor, for example an electrical motor, e.g. via a spindle drive with a threaded motor driven spindle and a nut member interacting with the spindle and connected to a heating element, e.g. via a resilient support as described herein.
The heating elements may be coated by an anti-stick coating to prevent food product from sticking to the heating elements.
The heating elements, preferably, each comprise a heatable block made from a metal such as aluminium to allow effective heat transfer. For example, one or more electric resistor heaters are combined with, e.g. embedded in, the block so as to controllably heat the block.
The pouch receiving assembly is adapted for receiving a pouch which initially contains the frozen flowable food product. The pouch is mountable on pouch receiving members which are part of the pouch receiving assembly. The pouch receiving assembly may be located above the pouch heating elements in the food product dispenser. This allows a pouch which is supported by the pouch receiving assembly to hang from the pouch receiving assembly between the heating elements.
-7- The pouch receiving assembly is moveable between a pouch mounting position and a pouch heating position. The movement of the pouch receiving assembly may be driven by a motor, a spring, a consumer, or combinations thereof, or any other suitable means.
The pouch is mountable on the pouch receiving assembly when it is in the pouch mounting position. Preferably, the pouch receiving assembly is substantially outside of the flowable food dispenser in the pouch receiving position to allow for easy mounting of the pouch. Preferably, in the pouch heating position the pouch receiving assembly is substantially directly above the heating elements to allow the pouch to be located between the heating elements.
The flowable food dispensing system further comprises a flexible pouch for containing the flowable food product in a frozen state. The pouch is placeable in the dispenser by mounting the pouch on the pouch receiving assembly.
The pouch is flexible when no food product is in the pouch. For example, the pouch is made from a flexible material such as a plastic. The flexible material may be for example ALOXPET12, NY15, PE70 or any other suitable material. The pouch is configured to transfer heat through the two main pouch surfaces to the frozen food product, such that the frozen food product is meltable by heat provided near the two main pouch surfaces by the pouch heating elements. Further the flexible material preferably resists shocks from falling. The pouch comprises a main chamber delimited between two opposed main pouch surfaces, also to be named vertical main pouch surfaces as these surfaces will be vertical when the pouch is in the dispenser between the heating elements.
The main chamber contains the flowable food product in frozen state.
-8- The main chamber has a top side and a bottom side. A spout connects to the main chamber at the bottom side and extends below the main chamber, e.g. vertically downward when the pouch is in the dispenser between the heating elements.
The spout serves as dispensing channel from the main chamber. The cross-section of the spout is smaller than the cross-section of the main chamber. This allows for a focussed outlet flow from the pouch, e.g. when dispensing into a glass. The spout also avoids that too big lumps of not yet melted food product would be dispensed. Preferably, mounting members for mounting the pouch on the pouch receiving assembly of the dispenser are located on the top side of the main chamber. For example, the pouch has a top portion at said top side wherein one or more pin receiving holes are present in the top portion allowing to suspend the pouch. The two main pouch surfaces are preferably are two flat main pouch surfaces in the frozen state of the pouch.
Atop side of the pouch is preferably formed by sealing two sheet that form the pouch together. Preferably, the pouch main surfaces have dimensions between 74 mm by 52 mm and 300 mm by 210 mm. This allows for a large contact area between the heating elements and the food product compared to the total food product in the pouch. A spout is located on the bottom of the pouch. The spout allows melted, or heated, food product to flow out of the pouch.
The spout may be arranged below a funnel shaped bottom portion of the main chamber of the pouch. The spout may be sealed hermetically by a removable or openable seal, for example by a tear-away portion at the lower end of the spout.
The spout, possibly after opening the seal, may be normally open to allow the melted food product to flow under the force of gravity out of the pouch.
-9- The spout is directed downward when the pouch is mounted on the pouch receiving assembly of the dispenser to allow better flow of the melted food product. Preferably, the bottom side of the pouch has a funnel shape to allow food product to flow easier out of the pouch. Preferably, the spout is located near a front side of the pouch, preferably said front side being proximate a front side of the dispenser when in the pouch heating position.
The mounting members are configured for mounting the pouch on the pouch receiving assembly of the dispenser. The mounting members are, preferably, located on the top side of the pouch so as the allow the pouch to hang form the mounting members under the pouch receiving assembly allowing for easier placement of the pouch between the heating elements.
Preferably, the mounting members are constructed so as to allow easy mounting and dismounting of the pouch. The mounting members may also be located on one or both of the two main pouch surfaces or on another suitable location on the pouch.
The two main pouch surfaces are substantially parallel to each other when the frozen flowable food product is contained in the pouch and they have a same shape. The pouch has a shape such that a distance between the two main pouch surfaces is smaller than a dimension of the two main pouch surfaces. This allows for a larger contact surface between the pouch and the heating elements and thus it allows for efficient heating and melting of the frozen food product. Preferably, the two main surfaces are two flat main pouch surfaces, preferably the two main pouch surfaces are substantially rectangular, more preferably the two main surfaces have a shape similar to a shape of the heating surfaces. This may allow for more efficient contact between the heating elements and the pouch. The frozen food product is stored between the main pouch surfaces, e.g. as a coherent block, below the top side and above the bottom side of the pouch, such that the frozen food product is adjacent to the two main pouch surfaces. This allows for improved heat transfer between the heating surfaces and the frozen food product since the contact surface area between the heating surfaces through the surfaces of the pouch and the frozen food product is bigger. A
-10- larger contact surface allows for better melting of the frozen food product and thus for more efficient dispensing of the flowable food product. The food product dispenser may further comprise a drip tray. The drip tray may be located on a food product container receiving area. The drip tray may allow food product to drip from a pouch mounted on the pouch receiving assembly without leaving visible residue on the food product dispenser. During melting of the frozen food product contained in the pouch, the pouch is mounted on the pouch receiving assembly and located between the heating surfaces. In embodiments, the pouch is continuously pressured by the heating surfaces during the dispensing of the melted product in cold state, thereby providing continuous conductive heat transfer between the heating elements and the frozen food product, thus effectively melting the frozen food product therein.
When dispensing cold, melted food product, it is envisaged that as soon as the food product melts, the food product flows out of the pouch through the open spout, e.g. directly into a food product container, such as a cup or a plate. The food product herein, preferably, flows directly from the spout into the food product container, not coming into contact with the flowable food product dispenser. The pouch is continuously pressured during the dispensing due to relative movement of the heating elements which move towards each other as food product is melted and flows out of the pouch. Possibly the food product dispenser does not have any buttons to start the dispensing process. The interaction between the user and the dispensing system is then for example restricted to hanging a pouch on the pouch receiving assembly and manually pushing the pouch receiving assembly into the dispenser. This operation is determined by the control unit of the dispenser as the start signal of a dispensing cycle. The dispensing of food product and removing of the pouch, e.g. into the waste container, may further be done fully automatically under control of the control unit. The system allows for controlled melting and dispensing of a frozen flowable food product. The frozen flowable food product is prepared and frozen in the pouch such that the pouch containing the frozen flowable food product has two main pouch surfaces that are substantially parallel to each other. This allows for more efficient melting of the frozen food product.
-11- Additionally, by freezing the food product in a pouch the frozen food product is easily handled by the consumer. For example, the frozen food product is easily placeable in the flowable food product dispenser.
The pouch receiving assembly allows for better handling of the pouch by the dispenser. Contact between the consumer and the heating elements is avoided by placing the pouch on the pouch receiving assembly instead of directly between the heating surfaces.
Further, since the frozen food product is contained in the pouch and the food product is dispensed directly from the pouch, no contact between the frozen food product and the dispenser is necessary, as is preferred. Thus, contamination and residue secretion in the dispenser is avoided. This is advantageous as contamination and residue negatively impact the taste of the food product and improves maintenance requirements of the system.
Itis a further advantage of the invention that a quality of the melted food product may be controlled by controlling the movement and temperature of the heating surfaces. The quality may further be improved by the large contact area and thus by the more efficient heat transfer between the heating elements and the pouch more efficiently melting the frozen food product.
It should be noted that no comminuting of the frozen food product as in the prior art is necessary and that the system instead may rely on precise heating and movement of the heating elements and on the contact area of between the pouch and the heating surfaces. Comminuting may negatively impact the performance of the system as it negatively impacts the contact area between the frozen flowable food product and the heating surfaces.
In an embodiment, the spout of the pouch is folded onto a main pouch surface preventing frozen food product from entering the spout during filling. The spout may be releasably affixed to a main pouch surface by glue, an adhesive label, or another mechanism. The spout may be unfolded before placing the pouch in the dispenser.
The spout of the pouch may receive heat from the heating elements less effectively than the main pouch surfaces, or may even be outside the path of travel of the heating elements, so not directly heated by the two heating elements at all. Therefore, any frozen food product which is located in the spout may not melt similarly to frozen food product located in the main chamber of the pouch, or not melt at all. Therefore, preferably, no frozen food product is located in the spout of the pouch in its initial frozen state. This may be achieved by folding the spout, e.g. onto one of the main pouch surfaces, ahead of filling the pouch with food product
-12- in liquid state. The fold then prevents the still liquid food product from entering the spout during filling of the pouch. Then the pouch and content are frozen. Upon use, e.g. ahead of placing the pouch onto the pouch receiving assembly, the user unfolds the spout. In embodiments, the user may also tear away a portion of the lower end of the spout to create a dispensing outlet of the spout. The same may be done by cutting off a lower closed end portion of the spout. Instead of folding, the spout to avoid that liquid food product enters the spout during filling, other approaches may also be considered. For example, a clamp is fitted locally on the spout, to close the spout from the main chamber of the pouch, e.g. a user removable clamp. In an embodiment, the mounting members of the pouch are formed by one or more holes in the top side of the pouch and the pouch receiving members are formed by one or more pins located on matching locations on the pouch receiving assembly. A combination of one or more pins and one or more holes provides for an easy to use combination for mounting the pouch on the pouch receiving assembly. The pouch may be easily mounted and dismounted on the pouch receiving assembly by moving the pins of the pouch receiving assembly through the holes of the pouch. The one or more pins may be orientated substantially horizontally so as to be able to support the pouch without the pouch being able to slide off.
In an embodiment of the flowable food dispensing system, the pouch receiving assembly is movable to a pouch disposing position which is preferably located above a waste container. An internal waste container is advantageous since it allows for more efficient disposal of empty pouches. For example, a consumer does not have to throw away each pouch separately but may throw away the contents of the waste container when it is full. Preferably, the waste container can contain more than 15, more preferably more than 30, empty pouches.
Preferably, the waste container is located behind and below the heating elements so that empty pouches can fall directly into the waste container. In an embodiment of the flowable food dispensing system the mounting members of the pouch are formed by one or more holes in the top side of the pouch and the pouch receiving members are formed by one or more pins, the one or more pins are retractable after dispensing of the flowable food product from the pouch, e.g. when at the disposing position.
-13- For example, two retractable and extendable pins are provided that are retractable in succession.
In an embodiment, first one pin is retracted, with the other, second, pin being offset from the centre of gravity of the empty pouch.
The retracting of the first pin then causes the pouch to swing about the second pin, e.g. further away from the heating elements.
Then the second pin is retracted such that the pouch falls away into a waste container.
The pins may be located in an asymmetrical manner on the pouch receiving assembly, wherein for example the first pin is located near a middle of the pouch receiving assembly and the second pin is located near a back side of the pouch receiving assembly.
This allows the pouch having a matching arrangement of holes to be mounted in only one way on the pouch receiving assembly thus increasing ease of use of the food product dispensing system.
The successive retracting of the pins such that the pouch starts to swing and then falls enhances the transfer into the waste container, e.g. the filling of the waste container with multiple empty pouches and/or the likelihood of the pouch falling into the waste container.
Furthermore, in case the one or more pins are retractable, the system may dispose of a used pouch automatically into the waste container without involvement of the consumer.
This makes the system easier in use.
When the pouch receiving assembly is in the pouch disposing position the pouch may fall easier into the waste container thus increasing effectiveness of the system.
In an embodiment, the main pouch surfaces are flat main pouch surfaces and the heating surfaces are flat heating surfaces.
This may increase the efficiency of heat transfer from the heating elements towards the pouch because the heating elements and the pouch may have a larger contact area.
In an embodiment the system further comprises a pouch entry door which interacts with the pouch receiving assembly such that the entry door is open when the pouch receiving assembly is in the pouch mounting position and closed when pouch receiving assembly is in the pouch heating position.
The heating elements of the dispenser may reach temperatures that are uncomfortable to touch thus advantageously the heating elements are shielded such that the consumer cannot touch them.
This may be done by placing the heating elements in a case and placing an entry door for the pouch receiving system.
In an embodiment of the entry door, it interacts with the
-14- pouch receiving assembly such that the entry door is open when the pouch receiving assembly is in the pouch mounting position and closed when pouch receiving assembly is in the pouch heating position. Thus, the consumer does not have to directly interact with the entry door.
In an embodiment, the flowable food dispensing system is configured so that the flowable food product flows directly from the spout into the food product container. Hence, when the pouch is in the pouch heating position the spout is located directly above a location where a food container, such as a bowl, a plate or a cup, may be located. This reduces contact of the food product with the dispenser thus reducing contamination of the dispenser. In an embodiment, the flowable food product is allowed to flow from the pouch solely under the force of gravity and pressure exerted by the pouch heating elements. Hence, the flowable food product when it is melted by the pouch heating elements naturally flows towards the spout and out of the pouch. In an embodiment the flowable food dispenser further comprises a normally open pincher which may be closed to seal of the spout of the pouch, for example for heating the flowable food product beyond the melting point, for example for heating a soup.
The normally open pincher may be a spring-opened slider which may be pressed against a block such that the spout is pressed between the slider and the block. The normally open pincher further may be removable from the dispenser to increase the ease of cleaning the system. The pincher may be closable by a motor, such as an electrical motor.
The normally open pincher does not have to engage when the food product to be dispensed is a juice which is best served cold to not change taste or nutritional value of the product. In contrast, a food product which may be served hot, such a soup, may be heated by the system by closing the spout with the normally open pincher. Thus by closing the spout by the pincher the frozen food product may be melted in the pouch without the food product flowing out of the pouch. The food product is thus heated in the pouch by the heating elements until it reaches a desired temperature. In an embodiment, the pouch initially comprises a tear-off seal for sealing the spout. A tear-off seal such as a tear-off portion may close the spout of the pouch such that no food product may leave the pouch before the seal is removed from the spout. Further, the pouch is sealed
-15- during transport and storage thus decreasing the change of contamination of the food product stored in the pouch. The invention further relates to the flowable food dispenser of claim 22.
The present invention provides for a flowable food dispenser configured to dispense an initially frozen flowable food product, which flowable food product is initially in a frozen state and is melted by the flowable food dispenser in order to be dispensed, e.g. in a cold melted state or, possibly, in a heated state at an elevated temperature, which dispenser comprises: - two heating elements configured to heat the initially frozen flowable food product whilst being contained in a flexible pouch so as to melt, and possibly heat to an elevated temperature, the flowable food product; and - a pouch receiving assembly, wherein each of the heating elements comprises a heating surface, wherein the two heating elements are located opposite each other with the heating surfaces facing each other, substantially parallel to each other and oriented vertically, wherein the heating elements are moveable relative to each other perpendicular to the heating surfaces by a drive mechanism , such that the heating elements are moveable between a pouch receiving position and a pouch flattening position, wherein the heating elements in the pouch receiving position are separated by a distance to allow a pouch containing the flowable food product in frozen state to be received between the heating elements and wherein the heating surfaces are closer to each other in the pouch flattening position, wherein the pouch receiving assembly comprises one or more pouch receiving members for mounting the pouch on the pouch receiving assembly using mounting members of the pouch, wherein the pouch receiving assembly is moveable between a pouch mounting position and a pouch heating position, wherein the pouch is mountable on the pouch receiving assembly in the pouch mounting position, and wherein the pouch is movable by said pouch receiving assembly between the pouch mounting position and the pouch heating position when the pouch is mounted on the pouch receiving assembly and wherein the pouch is located between the two heating elements when the pouch receiving assembly is in the pouch heating position, wherein the system is configured so that, with the pouch being in the pouch heating position, the drive mechanism of the two heating elements is operated so that each of two main pouch
-16- surfaces is contacted by a heating surface of a respective one of the two heating elements and so that the two heating elements are operated to create heat that is transferred from said heating elements through the two main pouch surfaces to the frozen flowable food product, so that in operation the frozen flowable food product is melted, possibly heated to an elevated temperature, so as to be dispensed, wherein the spout is directed downward when the pouch is mounted on the pouch receiving assembly of the dispenser.
The flowable food dispenser of claim 22 may have one or more of the features discussed herein with reference to the dispensing system. Advantages and functionalities of the dispenser are discussed herein with reference to the dispensing system.

Advantageous embodiments of the flowable food product dispensing system according to the invention and the method according to the invention are disclosed in the subclaims and in the description.
The invention is further illustrated and elucidated on the basis of the drawings.

Fig. 10 shows the pouch receiving assembly with the pouch receiving members in an extended position; Fig. 11 shows the pouch receiving assembly with the pouch receiving members in a retracted position; Fig. 12 shows the heating elements inside the dispenser in the pouch receiving position; Fig. 13 shows the heating elements inside of the dispenser in the pouch flattening position; Fig. 14 shows a pouch mounted on the pouch receiving assembly ready to be transported towards the heating elements; Fig. 15 shows the pouch of figure 14 between the heating elements in the pouch receiving position; Fig. 16 shows the pouch of figure 14 between the heating elements in the pouch flattening position; and Fig. 17 shows a view of the inside of the food product dispenser.
Fig. 1 shows a view of the food dispensing system 1 according to the invention. The food dispensing system comprises a food dispenser 2 and a flexible pouch 3. In the figure the pouch 3 is mounted on the pouch receiving assembly 4, which is in the pouch mounting position. The pouch 3 is mounted on the pouch receiving assembly 4 by hanging the mounting members 12 on the pouch receiving members 15.
The pouch 3 comprises a spout 5 and the food dispenser 2 comprises a waste container 6 for receiving empty pouches 3 that are emptied by dispensing the flowable food product. Which flowable food product may be any of a beverage, juice, smoothie, soup, processed cheese, sauce or any other food product which is sufficiently flowable.
The flowable food product is initially in a frozen state in the pouch 3 for storage and transport. The flowable food dispenser 2 is configured to melt and dispense the initially frozen food product.
The spout 5 allows melted food product to flow out of the pouch 3. The spout 5 is normally open to allow the melted food product to flow under the force of gravity out of the pouch 5. The spout 5 is directed downward since the pouch 3 is mounted on the pouch receiving
-24- assembly 4 of the dispenser 2. This allows for better flow of the melted food product towards a food product container such as a bowl, cup or plate (not shown) for receiving the food product.
Fig. 02 shows the food dispensing system of figure 1 from another side. The figure shows a pouch entry door 7 which interacts with the pouch receiving assembly 4 such that the entry door 7 is opened by the pouch receiving assembly 4. The pouch receiving assembly 4 may have a handle 16 which is a thinner part and a wider part where the pouch 3 is mounted as in figure 1. Wherein the handle 16 extends further from the dispenser 2. As the pouch receiving assembly 4 moves out of the dispenser 2 the pouch entry door 7 is pushed open by the widening of the pouch receiving assembly 4. In the figure 02, the pouch receiving assembly 4 is in the pouch mounting position and a pouch 3 is mounted on the pouch receiving assembly.
The pouch receiving assembly 4 may be retracted into the dispenser 2 by a motor 23, such as an electrical motor. Fig. 03 shows a front view of the food dispensing system 1 of figure 1. As can be seen from the figure 03 the waste container 6 is embodied as hanging in the dispenser 2. The waste container 6 is removable from the dispenser 2 by using the grip 8. Thus the waste container 6 may be emptied by pulling on the grip 8, removing the waste container 6 from the dispenser 2 and throwing any empty pouches 3 contained in the waste container 6 away.
Fig. 04 shows a side view of a food dispensing system 1 with the pouch receiving assembly 4 in the pouch heating position. In the pouch heating position the pouch receiving assembly 4 is retracted into the dispenser 2 such that the pouch 3 is hanging between the heating elements comprised in the dispenser 2. In this position the pouch 3 may be heated by the heating elements in order to melt the frozen food product contained in therein. As can be seen from the figure 04 in the pouch heating position the spout 5 of the pouch 3 extends outwards from the dispenser 2, allowing food product to flow out of the dispenser 2 without coming into contact with the dispenser 2. A food container such as a bowl, cup or plate may be placed below the spout 5 to receive frozen food product that flows from the spout 5.
05.
Fig. 05 shows the food dispensing system 1 with the pouch receiving assembly 4 in the pouch disposing position. The pouch receiving assembly 4 is retracted completely into the dispenser by the assembly motor 23 such that the pouch receiving assembly is located above the waste container 6 for disposing the empty pouch 3. After having disposed of the pouch 3 the pouch receiving assembly 4 may move to a position, such as the pouch heating position, wherein the thin part of the pouch receiving assembly 4 extends out of the dispenser 2.
Fig. 06 shows the food dispenser 2 with the pouch receiving assembly 4 in the pouch mounting position. The pouch receiving assembly 4 in this figure 06 is ready to receive a pouch 3.
The figures 01 — 06 show the food dispensing system 1 during various steps of the method according to the invention.
Figures 01 — 03 show a pouch 3 mounted on the pouch receiving assembly 4 wherein the pouch receiving assembly 4 is in the pouch mounting position. The pouch 3 in these figures contains a frozen food product.
Figure 04 shows the dispensing system 1 with the pouch receiving assembly 4 in the pouch heating position. In this position the frozen food product is melted and dispensed into a food container such as a bowl, cup or plate (not shown). After the pouch 3 is emptied the pouch receiving assembly 4 moves towards the pouch disposing position, seen in figure 05, and disposes the pouch 3 into the waste container 6. Finally the pouch receiving assembly 4 may return to the pouch mounting position to receive another pouch 3.
Fig. 07 shows a bottom view of the food dispenser 2 with a pincher 9 in an open state. The waste container 6 has been removed to allow a better view such that the opening 20 in the dispenser 2 through which an empty pouch 3 falls into the waste container 6 is visible. The pincher 9 in open state allows a pouch 3, more in particular the spout 5 of the pouch 3, to pass through the pincher. When the pincher 9 is in the open position a spout 5 located between the pincher 9 is not closed off and melted food product is free to flow out of the pouch 3.
Fig. 08 shows a bottom view of the food dispenser 2 of figure 07 with the pincher 9 in a closed state. In the closed state the pincher 9 may prevent food product to flow through the spout 5 of a pouch 3. This is advantageous for example for heating the flowable food product beyond the melting point, for example for heating a soup. The pincher 9 closes the spout 5 of
-26- a pouch 3 and does not directly come into contact with food product contained in the pouch 3. Thus the pincher 9 is less likely to need cleaning. Fig. 09 shows a flexible pouch 3 according to the invention filled with a single portion of frozen flowable food product, e.g. a smoothie. As preferred, the pouch initially contains between 0.1 and 0.5 litres of flowable food product in frozen state. The pouch 3 can be placed in the dispenser 2 as described herein.
The pouch has one main chamber 11a delimited between two opposed main pouch surfaces or main walls 11 of the pouch. This main chamber 11a contains the flowable food product in frozen state, preferably in absence of a head space. The main chamber 11a has a top side 10a and a bottom side 10.
A spout 5 is present at the bottom side 10 of the main chamber 11. In operation the spout 5 defines a focussed stream of flowable food product that is dispensed from the pouch. The flow cross-section of the spout 5 is significantly smaller than the cross-section of the main chamber 11. For example, the spout 5 avoids that too large chunks of still frozen material can be dispensed from the pouch.
As preferred, the pouch 3 including the spout 5 thereof is made of mono- or multilayer film material, e.g. having one or more layers of plastic material. As preferred, two sheets of such film material are joined, e.g. welded, along perimeters of the pouch to one another.
The spout 5 is, as preferred, not located centrally in the bottom of the pouch 3. Instead the spout 5 is located at side of the pouch seen in a view onto a main pouch surface 11. As shown herein, the spout 5 is preferably located at the vertical side of the pouch 3 that can be regarded as the “trailing side” when the pouch 5 held by the receiving assembly 4 is advanced from the pouch mounting position to the pouch heating position. In particular when the passage for the pouch, and preferably the door 7, are located at the front side of the dispenser, the offset location of the spout 5 has the benefit of the spout being located relatively close to the front of the dispenser. This, for example, facilitates placement of a food product container, e.g. a glass, underneath the spout 5. It also allows for a relatively small depth design of the dispenser, even when provided with a waste container 6 that is arranged further towards the rear of the dispenser 2.
-27- lt is illustrated that, as preferred, a bottom edge 10b of the pouch delimiting the chamber 11a extends at a downward incline from the opposite vertical side towards the spout 5. This enhances flow of food product to the spout.
As preferred, the frozen food product forms one coherent block in the pouch. This, for example, is the result of the main chamber 11a being filled with said product in liquid state, the pouch then being hermetically sealed, and the pouch being frozen so that the liquid turns into one solid block.
As preferred, the freezing process is done such that the main chamber surfaces 11a of the pouch are flat and parallel to one another. It is noted that in practice the flatness may not be obtained throughout the entirety of the surfaces 114, e.g. flatness primarily being attained in a central region and the surfaces showing some undulations towards the perimeter.
Itis preferred for the thickness of the pouch 3 to be relatively limited compared to the surface area of the main surfaces 11a so that a relatively large surface area is available for heat transfer compared to the volume within the pouch. Generally the distance between the two main pouch surfaces 11 is smaller than each of the width and the height of the two main pouch surfaces 11.
A top portion 13a of the pouch above the top side 13 of the main chamber 11 is formed by sealing the two mono- or multilayer sheets forming the main pouch surfaces and the spout together.
One or more mounting members 12, here one or more holes 12 provided in the top portion 13a, for mounting the pouch 3 on the pouch receiving assembly 4 of the dispenser 2 are located on a top side 13 of the pouch 3.
Initially, the film material spout 5 of the pouch 3 is folded upward onto a main pouch surface 11 along fold line 24. This fold line 24 is, as preferred, located at the join between the spout 5 and the main chamber 11a. The fold 24 prevents food product from entering the spout 5 during the filling of the food product in liquid state into the main chamber 11a of the pouch 3 ahead of the pouch containing the food product being frozen during production.
As shown in figure 09 the spout 5 is to be unfolded by the user ahead of the dispensing, e.g. ahead of mounting the pouch 3 to the pouch receiving assembly 4.
-28- As shown in figure 09, initially, the spout 5 has a removable lower end portion, here a tear- away portion 14, which hermetically seals the spout 5 at the outer end thereof during storage and transport.
The tear-away portion 14 is to be torn away by the user, e.g. just before mounting the pouch 3 on the pouch receiving assembly 4 or just after mounting the pouch 3 on the pouch mounting assembly 4.
The tear-away portion 14 here is defined by one or more notches 14a in one or more vertical seams of the spout 5.
It is shown in figure 09 that an adhesive label 14c is applied over the tear-away portion 14 and over an area (identified by dashes line) of the main surface 11a of the pouch to keep the spout in folded condition.
In use the label 14c is to be grasped by the user to release the folded spout 5 from the main surface so as to undo the seal of the top of the spout by the fold (this is shown in figure 09). Later, the user can pull on the label 14c to thereby tear the tear-away portion 14a from the spout so that the spout is open at the lower end thereof.
The pouch 3 can be mounted on the pouch receiving assembly 4 by the mounting members 12, e.g. the holes 12 being matched with the pins 15. The pouch 3 will then hang from the mounting members 15 under the pouch receiving assembly 4.
The pouch 3 is configured to transfer heat through the two main pouch surfaces 11 to the frozen food product, such that the frozen food product is meltable by heat provided by the heating elements 17.
Figure 09 schematically denotes the perimeter of the heating elements 17, which are preferably rectangular. It is illustrated that the spout 5 extends below the heating elements 17, so the spout 5 will not be in direct contact with the heating elements 17 during operation of the dispenser 2. As explained, the pouch is filled so that only the single main chamber 11a thereof contains the frozen flowable food product and the spout 5 is then empty. The latter avoids any frozen product from forming an obstruction in the spout, and/or avoids discharge of a frozen plug from the spout.
-29- It will be appreciated that instead of a fold line 24 other measures can be provided to seal the top end of the spout 5 from the main chamber 11a so as to avoid filling liquid product into the spout ahead of freezing the pouch. For example, a clip is applied at the location of the line 24 thereby avoiding the need for folding the spout 5.
It is noted that, in embodiments, the spout 5 could also be configured as an injection molded plastic fitment that is secured to the bottom side of the main chamber 11a. For example, the fitment then has a squeezable section, that can be squeezed to close the spout.
The frozen food product is stored between the flat main pouch surfaces 11, below the top side 12 and above the bottom side 10 of the pouch 3, such that the frozen food product is adjacent to the two flat main pouch surfaces 11. This allows for effective heat transfer between the heating surfaces 18 and the frozen food product since the contact surface area between the heating surfaces 18 through the flat main sides 11 of the pouch 3 and the frozen food product is big. A large contact surface allows for better melting of the frozen food product and thus for more efficient dispensing of the flowable food product.
The bottom side 10 of the pouch 3 has a funnel shape and the spout 5 may be folded along the fold line 24 to prevent food product from flowing into the spout 5.
Figs. 10 and 11 show the pouch receiving assembly 4 with the pouch receiving members 15 and the handle 16. Fig. 10 shows the pouch receiving assembly 4 with the pouch receiving members 15 in an extended position and fig. 11 shows the pouch receiving assembly 4 with the pouch receiving members 15 in a retracted position. In these figures the pouch receiving members 15 are embodied as retractable pins.
The pouch receiving members 15 are configured for mounting the pouch 3 on the pouch receiving assembly 4 using the mounting members 12 of the pouch 3 when the pouch receiving members 15 are in the extended position. When the pouch 3 is emptied by the dispenser 2 the pouch receiving members 15 may retract causing the pouch 3 to fall from the pouch receiving assembly 4, and preferably into the waste container 8. The pouch receiving members 15 are retracted asymmetrically, with the pouch receiving member 15 closer to the handle 16 retracted first. This allows the pouch to fall more easily into the waste container 6 which is located at the back of the dispenser 2.
Figs. 12 and 13 show the heating elements 17 inside of the dispenser 2 mounted on a dispenser frame 21. Fig. 12 shows the heating elements 17 in the pouch receiving position
-30- and fig. 13 shows the heating elements 17 in the pouch flattening position. Each of the heating elements 17 comprises a flat heating surface 18. The two heating elements 17 are located opposite each other with the flat heating surfaces 18 facing each other, substantially parallel to each other and oriented substantially vertically.
The heating elements 17 are moveable relative to each other, in particular in this embodiment one of the heating elements 17 moves towards the other, such that the heating elements 18 are moveable between the pouch receiving position of figure 12 and the pouch flattening position of figure 13.
The moveable heating element 17 is moveable by threaded motor driven spindle 25 and nutplate structure 26 which are connected to the heating element 17 via guided rods 27. Springs 27a provide resiliency between the drive motor spindle 25 and the heating element
17.
The heating elements 17 in the pouch receiving position are separated by a distance to allow a pouch 3 to be received between the heating elements 17 and the heating elements 17 are closer to each other in the pouch flattening position.
A frozen flowable food product in a pouch 3 is allowed to be placed between the heating elements 17 in the pouch receiving position. When the heating elements 17 move towards each other the food product melts and flows downwards away from the heating elements 17 without coming into contact with the heating elements 17. This prevents contamination of the heating elements 17 by the food product. The heating elements 17 are in contact with each other in the pouch flattening position as can be seen in figure 13. Movement between the pouch receiving position and the pouch flattening position allows the pouch 3 to be in constant contact with the heating elements 17 as the frozen flowable food product in the pouch 3 is melted. Movement of the heating elements 17 may be driven by a motor 19, for example an electrical motor 19. Figs. 14, 15 and 16 illustrate the process of mounting a pouch 3 on the pouch receiving assembly 4 which then transports the pouch 3 between the heating elements 17 where the pouch 3 is flattened. The pouch receiving assembly is guided by assembly guide 22.
-31- Fig. 14 shows a pouch 3 mounted on the pouch receiving assembly 4 ready to be transported towards the heating elements 17. Fig. 15 shows the pouch 3 of figure 14 between the heating elements 17 which are in the pouch receiving position . Fig. 16 shows the pouch 3 of figure 14 between the heating elements 17 which are in the pouch flattening position.
The food product is melted by the heating elements 17 as they move between the pouch receiving position and the pouch flattening positions shown in figs. 15 and 17.
During melting of the frozen food product, the pouch 3 is mounted on the pouch receiving members 15 between the flat heating surfaces 17. There the pouch 3 is continuously pressured by the flat heating surfaces 17 as they move between the pouch receiving position and the pouch flattening position. Heat transfer is thereby provided between the heating elements 17 and the frozen food product, thus effectively melting the frozen food product in the pouch 3.
As the flowable food product melts it flows out of the pouch 3 through the spout 5 into a food product container, such as a bowl, a cup or a plate. The pouch 3 is continuously pressured due to movement of the heating elements 17 which move towards each other as food product is melted and flows out of the pouch 3. After the food product has flowed out of the pouch 3 the heating elements 17 will move back towards the pouch receiving position. Afterwards the pouch receiving assembly 4 may move to the pouch disposing position for disposing of the pouch 3.
Fig. 17 shows a view of the inside of the food product dispenser 2. The figure 17 shows the assembly motor 23 for moving the pouch receiving assembly 4 between the pouch disposing position, pouch flattening position and pouch mounting position. The figure further shows the pincher motor 28 for closing the pincher. The entry door 7 is not shown.
