DE102023001938A1 - Hot beverage brewing device and capsule with a content for a hot beverage - Google Patents

Abstract

This device and the capsule are ideal for preparing espresso or coffee outdoors. The device is simply constructed and only needs a few parts. However, you don't have to compromise on the quality of the coffee, on the contrary: the coffee taste is even more intense and better because the coffee is brewed directly into the capsule and served in the cup without intermediate storage. The device has no pump, no water tank and no heating block for heating the water. The capsule has a double-chamber design. The water and the coffee powder are placed in separate chambers in the capsule during production. The heating of the water-coffee mixture is carried out by a heating element that is built into the capsule. The capsule contents are heated up in a flash, excess pressure is generated inside and the coffee flows from the capsule directly into a coffee cup.

Description

The invention is a device and a coffee capsule that contains all the ingredients for making hot coffee. The drink is brewed directly into the capsule using a heating element built into it. The coffee, for example, is also poured directly from the capsule into the cup without any intermediate steps.

There are numerous capsule machines that use capsules to make coffee or espresso. The capsules contain a small amount of coffee powder (approx. 5 - 6 grams). There is also an integrated filter that filters the coffee as it flows through. When preparing the capsule in the machine, it is pierced in several places and hot water flows in on one side while the coffee flows out the other. However, there are also capsules that already contain the water-coffee mixture. The coffee first flows into a funnel and then through a half-pipe-shaped container to the cup. Unfortunately, these detours cool the coffee more or less, which is why the first coffee is usually slightly cooler than the next coffee, for example if a second capsule is to be prepared immediately afterwards.

From the US 5,325,765 A filter cartridge is known in which the coffee powder is held in a filter bag inside the cartridge. The outer shell of the cartridge is made of a water-impermeable material, while the filter bag is made of a water-permeable material. The filter bag has a downwardly tapered shape so that a chamber is formed in the lower area of the filter cartridge between the outer shell and the filter bag. To extract the coffee powder, the cartridge is pierced on both sides by an upper and a lower piercing device.

The invention EP 1554958B1 concerns coffee machines for brewing powdered coffee packed in a capsule. The coffee machines in question here are mainly used in the home. Compared to conventional coffee machines equipped with a grinder for grinding the coffee beans, a fundamental advantage of the coffee machines in question here is that a high-quality coffee drink can be brewed by using capsules, especially since the coffee powder has an optimal degree of grinding and is packed airtight in the capsules. In addition, the coffee machines are subject to relatively little contamination from coffee powder.

The invention EP 2476633B1 relates to a capsule, system and method for preparing a beverage. Here, the stiffening region is arranged in particular rotationally symmetrically around the penetration region, wherein the stiffening region is formed as at least one section-wise depression essentially in the circumferential direction in the base, and is protected.

From the DE 27 52 733 A cartridge is known which contains a substance for the production of a beverage with a corresponding machine. This cartridge has a sealed housing with an acute-angled truncated cone shape and is usually made of aluminum sheet.

From the WO 2010/041179 A1 is a capsule for making beverages such as coffee. The capsule can contain ground coffee and has a top with a weakened area built into it.

From the EP 1 944 248 A1 A plastic capsule is known which contains a powder for the production of a beverage with a corresponding machine. A reinforced wall is built into a central area of the base of the capsule to prevent the base from bending immediately before penetration.

Such machines have complicated components such as the thermoblock, high-pressure pump, monitoring elements, control system, etc. A disadvantage of these machines is that the thermoblock in particular, where the water is heated, needs to be descaled more or less depending on the level of lime in the water pipe. In addition, every time a coffee is prepared, coffee residues stick to the machine parts, which can lead to mold formation over time. The components that direct the flow of coffee from the capsule to the cup are particularly at risk. The machines are also relatively complicated because they have many elements that can be damaged by lime water. The brewing unit in the machine is one of the most expensive components after the high-pressure pump.

However, there is still no water dispenser or water gun that can brew coffee!

The object of the invention in patent claims 1 to 18 is to create a capsule that can almost completely replace a coffee machine and can brew and pour a hot beverage (coffee, tea).

This problem is solved with the features listed in patent claims 1 to 18.

This device and the associated coffee capsule (or tea capsule) are relatively simple in construction and are intended as outdoor leisure fun items with a practical use. The capsule itself is almost a coffee machine, or a simple device for preparing a hot drink (coffee, tea, etc.). The hot drink brewing device has no pump, no water tank and does not need an external water supply. It has, among other things, a power source, a switch and a holder for the capsule.

The capsule 1 is slightly larger than conventional coffee capsules, weighs around 50g including its contents, and should have an internal volume of around ^30-50cm3 . There are two chambers built into the capsule, separated from each other by a thin partition wall with predetermined breaking points. One chamber, which is located in the upper area when the capsule is placed vertically in a brewing position, is the water chamber 2, while the lower chamber is a coffee powder chamber (or tea powder chamber) 3. The partition wall 4 can break or tear if there is slight excess pressure in the water chamber, causing the water 5 to mix with the dry coffee powder 41. A heating element 6 is built into the water chamber, which is integrated into the capsule or capsule wall 7 in the form of a heating coil 8, or is positioned in the middle of the water chamber like a heating pin (stainless steel, ceramic, etc.) 9. The heating element can be a thin spiral heating wire or a coil that is integrated directly into the capsule wall or consists of the capsule wall material. The capsule has a second predetermined breaking point 10 (or perforable foil that is installed at the very bottom in the vertical brewing position (e.g. at the capsule tip 11), which will only tear or break when there is a higher pressure inside the capsule and releases the contents (the coffee 12) outwards into the cup 13. This can be an aluminum foil that has radial predetermined breaking points 14 that are arranged in a ring shape or radially in a line from a point 15 in the middle ( 1 ). A coffee filter 16 is installed directly above the predetermined breaking point and its job is to filter the coffee-water mixture 17 that will flow out of the capsule. The capsule has two isolated electrical contact points 18 (contact pads) or concentrically arranged electrical contact rings 19 on the outer wall in two places, which are electrically connected to a heating wire, heating coil 8, or the heating element 6 inside or in the capsule wall. The electrical contact points are preferably built in the form of two concentric rings 19. Because the dry coffee powder 41 and the water 5 (sterile water or distilled water!) are strictly separated from each other, the contents have a long shelf life and can be kept or stored in a similar way to conventional coffee capsules. If distilled water is in the water chamber, then you should add a few ingredients to the coffee powder that compensate for elements missing in the water (e.g. salt, calcium, minerals, etc.). This capsule also has stable inner walls that can withstand around 4 - 10 bar. The lower predetermined breaking point should give way after around 1.5 - 3 bar and the coffee should then be able to flow downwards. The partition wall/separating film inside the capsule can be equipped with predetermined breaking points on the edge through which the hot water penetrates the coffee powder chamber under pressure in several water jets, swirling the powder around really strongly and thus creating a relatively homogeneous mixture.

To prepare the coffee, this capsule is placed in a simple device 20, which consists only of a frame or housing 21 with a funnel or a capsule receiving chamber 22, two con contact pins or contact rails 23, a switch 24 and a power source 25. As soon as the capsule is put into the funnel 22, the user closes a small lid 26 in which two current rails or current contact pins 23 are located. The contact rails or pins can be spring-loaded and can rest directly on the current contact points 18 of the capsule 1 when the lid is closed. Because the capsule has two concentric metal or foil rings 19, which can also be aluminum foil rings, for example, as current contact points, you don't have to pay much attention to where the contact points are when inserting the capsule. The only important thing is that the capsule is facing downwards with the narrower surface / tip 11. The concentric rings are attached to the wider surface 27 with the edge 28. A cup 13 is placed under the funnel in the frame of the device. After the lid is closed, the user activates a switch 24, which closes a circuit from the battery 25 of the device with the heating element of the capsule and the heating element inside the capsule (or on its wall) begins to heat the water 5 in the water chamber 2 at lightning speed. Because the amount of water is relatively small (for an espresso approx. 15 - 25ml), very high temperatures of over 100°C can be reached within seconds. As soon as the water inside is heated to approx. 101°C, the separating film / partition wall 4 between the chambers collapses and the water from the water chamber mixes with the coffee powder 41 below. The temperature drops abruptly due to the mixing, but then it rises again within seconds to approx. 102 - 105°C, which creates enough steam pressure that can also tear open the lower predetermined breaking film 10. From then on, the coffee, espresso or tea flows into a cup below. The coffee is really hot, freshly brewed and poured directly from the capsule into the cup. The device also has an electronic control that stops the brewing process after about 10 seconds or interrupts the circuit to the heating element in the capsule. Of course, a temperature sensor 29 and a controller 30 can also be built into the device, whereby the coffee temperature can be adjusted slightly and temperature monitoring of the brewing process is possible. There is also an electronic control 31. The device can be equipped with a rechargeable energy source. A power connection for a charger should also be integrated. USB connections 32 are ideal for this because any USB power supply can then be used ( 5 ).

Because this device is quite simply constructed, it weighs very little and can be built very small. The housing can be a simple wire frame/skeleton that can be folded using built-in joints, in which a funnel (can also be made of wire mesh or a ring holder) is positioned over a cup placed underneath. No piercing needles or perforators, no water supply and, above all, no heating block and no high-pressure pump are required. This makes the device extremely simple, but the quality of the coffee preparation/espresso creation is the main focus. Although it is extremely simple in design, the device brews first-class coffee/espresso that is really hot and tastes delicious. The device weighs very little and can only weigh around 100g. Most of the weight of the device is the battery. Because the power consumption is relatively low and the battery is only charged for a short time (approx. 10 seconds), the user can prepare approx. 100 - 200 espressos with one battery charge, which is sufficient for a medium-sized group of people on a nature hike, for example.

The power button 24 on the housing/frame of the device will activate the heating element in the capsule or energize it, which causes the water in the capsule to heat up very quickly. The heating element should be made of a neutral material (precious metal, stainless steel, ceramic, etc.) and should not release any metal residues into the water when heated, as this would make the coffee undrinkable. Precious metals or heat-resistant materials (e.g. ceramic) can be very suitable.

In contrast to the current state of the art, the heating element is now built directly into the capsule. This makes a water heater in the adapter superfluous. The built-in water chamber in the capsule, separate from the coffee powder chamber, also makes the device simpler because no water tank is required. The coffee is completely brewed directly in the capsule. By heating the water directly in the capsule, steam pressure is created inside the capsule, which pressurizes the capsule contents downwards through the built-in filter in the capsule and directly into the cup. The design of this device is therefore greatly simplified, so that it can be optimally designed as a portable device.

It goes without saying that additional features or elements can be integrated into the device, such as a touch display 33, a WLAN interface (WLAN module 34, whatever), a USB interface that can be used not only for charging but also for bidirectional data exchange with a PC or smartphone. The data exchange function with a PC would be interesting for research, coffee brewing process optimization or statistical purposes. This would enable every user to find the optimal Determine the values of the current flow in the heating element for the coffee brewing process that would best suit its taste and adjust them using a built-in controller in the device or via the interface.

The electrical current is conducted into the capsule through two contact points on the outside of the capsule, via two electrodes or contact pins on the device, and the heating element, which is built into the capsule or integrated into its capsule wall, is heated up in a flash. The capsule contents (coffee powder and water) mix as soon as the pressure in the water chamber exceeds the capacity of the barrier/partition wall above the predetermined breaking points, and the mixture in the capsule is then heated again very quickly, generating another, slightly higher overpressure in the capsule. Because the capsule is in the funnel or in a capsule receiving chamber in the device, it is somewhat protected and cannot easily expand or burst uncontrollably. The capsule can therefore withstand higher pressures than if it were outside the chamber. The current will only flow through the heating element for a very short time, heating it to approx. 110 - 130°C. This is usually enough to heat around 25ml of water-coffee mixture to over 105°C in a flash. The heat creates a steam pressure inside the capsule, which increases rapidly. Heating the contents and creating pressure takes a few seconds or up to several dozen seconds, depending on how the heating element is designed. The excess pressure causes the tip of the capsule to break at a predetermined breaking point, perforate it, or open in a ring shape if the predetermined breaking lines are arranged radially to a point. The coffee then flows directly into the coffee cup through the tip of the coffee capsule, which opens automatically due to the excess pressure. A tiny area in the tip of the capsule can be equipped with a flow moderator / disruptor / slower in the form of a small part that is constructed like a solid foam (mini filter) 35, which slows down the flow of coffee (tea flow) somewhat and swirls it so that no sharp jet shoots onto the cup. A cover or cup lid 36 with a hole in the middle can also be placed on the cup to prevent splashes from the cup. Usually, however, the flow moderator / disruptor is completely sufficient. The pressure in the capsule increases to a few bars within seconds, so that the contents are then pressed downwards because there is no other way for the coffee to drain away. The capsule is well protected from the sides and from above by the funnel walls, so the only way down through the capsule tip remains free.

During production, a small tube 37 can be built into the capsule to further facilitate the flow of coffee into the cup.

The heating element inside the capsule should be as simple as possible. This can be a very simple metal spiral (e.g. stainless steel, ceramic or aluminum spiral) or coil that is "scratched" into the capsule wall or positioned in the middle. The aluminum capsule wall can serve as a heating element if it is cut spirally and insulated, or has conductor strips that are arranged quite thinly along the insulated wall so that the current can flow like a spiral or in narrow conductor tracks with high electrical resistance. The pressure is generated solely by the heat inside the capsule and the steam generated there displaces the water-coffee powder mixture from the capsule. Because no pump or water heater is necessary, the device can be built as small as a thick felt-tip pen or a cigarette packet.

As soon as the capsule filled with water is supplied with electricity, the water mixture inside is heated within seconds. The rest is done by the steam inside the capsule. An electronic control 31 can be installed there, which monitors the power supply and switches off the power supply after a few seconds so that no melt is produced from the heating element. A temperature sensor can also be installed in the capsule receiving chamber / funnel, but this is not absolutely necessary.

The way the device works allows for very fast coffee preparation. It can prepare a really hot espresso in less than 10 seconds. The heating element in the form of a metal, stainless steel, tungsten or aluminum heating coil, which is integrated into the capsule wall or in the form of a pin positioned vertically in the middle of the capsule, can be used to heat the water-coffee mixture.

It should be mentioned that the capsule must be able to withstand the heat of the internal heating element, and that the capsule wall must be made of a material that would not melt at 150°. Aluminum is suitable for this. The capsule receiving chamber in the device should also be heat-resistant. However, the device can be equipped with a temperature monitor or current flow regulator that would prevent the heating element in the capsule from overheating. As a rule, it would be completely sufficient if the heating element could be heated to a maximum of 130 - 140°C outdoors. If it is placed in water, it does not reach this temperature, but it can heat the water to over 100°C.

The device can be equipped with an electronic temperature controller / regulator 30 and a temperature sensor which switches off the power supply when a certain temperature is reached. Or the heating element can be coupled to a "safety point" outside the capsule which is interrupted after a few seconds by the flow of current through the melting process. However, no current conductor or fuse should melt inside the coffee capsule. These can be installed outside the capsule. The capsule receiving chamber of the device should prevent the capsule from expanding, so it should be built sturdily and be made of a heat-resistant material. Ceramic, metal or certain heat-resistant plastics are suitable for this. Long and narrow capsules / cigarette-shaped capsules can be used very well as coffee capsules. A current line (e.g. made from parts or strips from the capsule wall) could be installed along the inside of the capsule, which would then be quickly heated by the electrical resistance. In this case, the contact points could be installed at each end of the cigarette-shaped capsule or both at one end. Whether the capsule is made of metal foil, wood, paper, bamboo or heat-resistant plastic is up to the manufacturer. The capsule itself does not necessarily have to be able to withstand very high pressure values. The stability is supported by the funnel / capsule receiving chamber, so that a few bar of resistance is sufficient. However, it can withstand the higher pressure if it is in the capsule receiving chamber because it is supported on almost all sides by the funnel / chamber walls. In general, pressure values of 2-10 bar are completely sufficient because these values are generated directly in the capsule and not by a pump outside, which would have to accept significant pressure losses through the pipes. The 3-5 bar pressure generated directly here is almost analogous to a pressure pump that works in a coffee machine, which generates 20 bar.

Because the capsule already has the heating element inside, you would think that it would be more harmful to the environment than conventional capsules, but this is not necessarily the case. The heating element consists of a metal spiral, which can also be part of the capsule wall that is built into it, or integrated into the capsule wall. Integration into the capsule wall is an optimal solution because no extra metal parts have to be installed. All that is needed is a special "cut" in the conventional capsule wall, which converts the wall into narrower conductor tracks that can be heated by the flow of electricity. Nothing more is necessary. This does not make the capsule heavier, nor does it make its construction more complicated. The narrow aluminum conductor tracks (windings) 8, which are "scratched" into the capsule wall and form a heating spiral, conduct the current directly from the contact points and heat up in the process. The conductor tracks can be designed in strip form, for example, around 1 mm or slightly wider, and with a total length of around 15-30 cm of all turns 38 to the capsule wall 39, they offer enough electrical resistance so that they can be heated up instantly. However, they should not be subjected to such high current that they melt or burn, but only so that they heat up to around 110 - 130°C, which they almost never reach due to the water in the capsule. The exact current strength and voltage can be regulated using a current flow controller so that the desired water temperatures of over 100°C are achieved. The coffee water in the capsule heats up within seconds, generating the necessary pressure that opens the tip of the capsule, which is positioned downwards, and allows the coffee to flow directly into the cup. The filter at the bottom of the tip prevents the coffee from escaping explosively and slows down the flow speed slightly so that it can land in the cup quietly and without splashing.

The electronic control limits the current to precise values, thus protecting the user and the device from burns. The outer wall of the capsule receiving chamber is designed to insulate the heat emitted by the capsule. This means that the device can be touched safely with your hand. The outer wall can be designed so that it only heats up slightly, even if you use several capsules in a row and prepare several coffees.

With slight adjustments, the device could also take balls of pressed coffee powder and prepare them into coffee. However, it would then have to be equipped with a water tank and a heating element in the form of an injection needle that pierces the ball.

In one variant, the lid 26 can be separated. Because the battery 25 and the contact pins 23 are built into the lid, coffee can be brewed directly by touching the power contact points of the capsule, even without the device and the capsule receiving chamber. To do this, you would only need to use a cup lid 36, in which the capsule is inserted into a hole in the middle up to the upper edge 28 with the tip 11 pointing downwards and then touch the power contact points of the capsule with the lid from the device. The cup lid can be equipped with concentrically arranged recesses 40, which would be suitable for different cup sizes. In the middle, the cup lid has the hole in which the capsule is inserted ( 6 ). The edge 28 of the capsule, on whose surface the electrical contact points of the capsule are also built, prevents the capsule from sinking completely and falling into the cup. When the current is passed through the electrical contact points, the heating element in the capsule is heated and the brewing process can begin. However, you should be careful not to touch the capsule again because it is too hot and could cause burns. Instead, you lift the entire cup lid off and the capsule can then be put to one side to cool down, for example.

The device 20 can be built extremely simply and consist only of a wire frame. The funnel for the capsule holder can also be built in the form of a ring holder 42. In this way, the entire device would weigh only a few dozen grams ( 4 ).
