Improving Coffee Extraction from Coffee Pods

Coffee capsule machine that can recognize the identification code on a coffee capsule, then automatically extract the coffee according to the code. The machine has a camera positioned to view the capsule's code when it is in the extraction chamber. The camera captures an image of the code, which is decoded by the control circuit. The code identifies the coffee type and the circuit sets the extraction parameters accordingly, like water volume and temperature. The circuit controls the heating and extraction units to deliver the customized extraction for the identified coffee capsule.

Drop-in coffee machine that automatically extracts coffee from capsules while preventing waste by using a slanted drip container, extracting the coffee, and then automatically ejecting the used capsule shell. The machine has capsule detection using optics and a driving unit that moves the water injection unit to engage or disengage the capsule.

A drawer-type capsule coffee machine that can automatically extract and brew coffee from capsules without any manual operation. The machine has an identification assembly to read patterns on the capsule. When the extraction assembly is exposed, the identification assembly reads the pattern and sends a signal to drive the extraction assembly to slide in. A cutter assembly above aligns with the capsule to puncture it. The extraction assembly then slides back out to brew the coffee.

Capsule coffee machine that prevents dripping after brewing. The machine has a brewing assembly that connects to a nozzle for dispensing the coffee. The nozzle has a liquid discharge passage on its outlet end. An elastic pressurizing member like a valve blocks the passage when the pump is off. This prevents residual coffee from dripping. When the pump starts, pressure opens the valve and coffee goes into the nozzle instead. This selective flow prevents dripping without extra parts like discharge tubes.

Coffee filter capsule that provides improved crema extraction and filtering versus reusable capsules. The capsule has a cup body with a cover that contains a pressurizing piece above a filter holder and filter sheet. Water is inletted through the bottom and pressurized by the piece during brewing. The pressure helps extract crema while filtering the coffee.

Device and method for extracting liquid from capsules containing powders like coffee. The device has a pump, flow rate sensor, and control unit. The pump supplies pressurized water to a capsule. The flow rate sensor detects the water flow rate. If the flow rate is lower than a threshold, the pump is stopped and restarted to try to clear blockages. After a certain number of restarts, an extraction fault is displayed.

A coffee capsule for making intense and aromatic coffee extracts in high-pressure coffee machines using a tearable foil extraction member. The capsule has a larger volume and opening diameter than existing capsules. This allows packing more coffee grounds for a stronger extraction. The ratio of the opening size to the tearing portion on the extraction plate is optimized to limit extraction of certain undesired coffee compounds.

Machine for opening and extracting beverages from single dose packages such as coffee capsules with a reliable and simple mechanism to open the capsules. The machine uses a dual action actuator that pushes the package against opening protrusions to cleanly puncture it, while also using a back pressure element to reinforce the contact. This provides a consistent and reliable opening mechanism that can be used in beverage machines.

A coffee machine that can brew a high quality drink from a very high percentage of capsules by reducing blockages. The machine uses a pump to push water through a coffee capsule. The pump power is controlled based on the flow rate into the capsule. If the flow decreases below a certain threshold, indicative of blockage, the pump power is reduced to prevent a complete blockage. This allows brewing to continue, albeit at a slower rate, rather than prematurely stopping due to safety features.

Brewing large volumes of filter coffee using a coffee machine that normally brews small espresso shots. The invention is a capsule for brewing beverages like coffee in a coffee machine. The capsule has a large size like a filter coffee capsule, but inside it has a separation element that divides the capsule into two regions: an empty region and an extraction material region filled with coffee. A liquid channel traverses the empty region. The extraction material region is pierced by the coffee machine's injection and extraction needles to brew the coffee. The separation element prevents the brewed coffee from entering the empty region containing the liquid channel. This allows the capsule to be filled with a small amount of coffee suitable for espresso brewing, while still brewing a large volume of liquid like filter coffee.

A biodegradable coffee cartridge that improves extraction efficiency compared to plastic cartridges. The cartridge is made from a biodegradable material like starch (>70%), fibers, proteins, lipids, and biodegradable resins.

A coffee capsule cup with a shape that allows needles to consistently penetrate the plastic bottom. The cup has an outwardly oriented annular wall with a circular plate at the bottom that is offset inwardly relative to the wall. The connection between the plate and wall is an inwardly inclined annular surface that forms a thin injection membrane. This shape prevents the bottom from deforming inwards when needles pierce the membrane, ensuring full penetration and a complete extraction.

A coffee cartridge system that allows users to roast, grind and brew coffee from unroasted beans within a single sealed cartridge. The cartridge has a chamber containing unroasted coffee beans. The cartridge walls are heat resistant and one wall has milling means. An apparatus secures the cartridge, grinds the beans using a ram, perforates the walls, extracts the coffee with hot water, and dispenses the brewed coffee. The apparatus can also roast the beans remotely before grinding and extraction. The system enables convenient, single-serve coffee brewing with freshly roasted and ground beans.

Espresso coffee capsule with a filter that improves extraction quality by creating a more dense, even layer of crema and avoiding air bubbles in the coffee. The filter is designed to provide the optimum hydraulic resistance for emulsifying the espresso coffee during extraction while still allowing the water to pass through. This creates a more even, consistent flow of coffee that prevents air bubbles from forming.

A composition for making a coffee beverage that extracts fully to give a milky coffee beverage in a single preparation step. The composition contains roast and ground coffee with a particle size of 700-1250 μm and milk powder with a particle size of 50 μm to 3 mm.
