Coffee Pod Designs

Method and apparatus for brewing and extracting coffee to improve flavor profile and reduce waste. The method involves extracting coffee using water flowing in multiple directions through the grounds. This includes top-down and bottom-up extraction as well as left-right and right-left extraction. Electronically controlled valves regulate the water flow based on factors like solubility and grind size. This uniformly extracts coffee solubles and reduces waste compared to single-direction extraction. It also reduces the need to change grind size to calibrate flavor.

Coffee extraction and refining device that compactly packs coffee grounds in a filter to improve extraction efficiency. The device has a table, bracket, chassis, connector, and filter. The chassis contains a water tank with a pressurizing cylinder and a connector welded to the bottom. The connector is attached to the filter. When the device runs, a piston in the cylinder squeezes the coffee grounds in the filter to compact them. This reduces the gap between the coffee particles, allowing hot water to fully contact and extract more flavor from the coffee.

Multifunctional coffee extraction cup with adjustable extraction time and flavor control. The cup has two interchangeable extraction chambers - a conical chamber and a trapezoidal chamber - that allow water to flow through coffee at different rates. This increases extraction time and flavor. The cup also has a shut-off device with intercepting holes that can be opened or closed to further control extraction. The chambers can be swapped, the extraction time adjusted, and the flavor fine-tuned by intercepting water flow.

A coffee capsule that can be filled multiple times with coffee powder and reused, reducing waste and cost compared to disposable capsules. The capsule has a shell to hold the coffee and a sealing film covering the shell opening. A hoop compresses the film edge against the shell to seal it. This allows the capsule to be filled and sealed with coffee multiple times while still fitting capsule coffee machines.

A capsule coffee machine with a cover that opens and closes to reveal the capsule chamber. The cover has a sliding rod inside that connects to the brew head. When the cover is closed, the rod moves to separate the brew head from the seat. When the cover is opened, the rod moves to bring the brew head and seat together. Opening and closing the cover thus moves the brew parts to insert/remove capsules.

Coffee manufacturing method and apparatus to maximize the original taste and flavor of coffee by minimizing flavor loss during brewing. The method involves roasting, grinding, closed extraction, simultaneous cooling, and filling. Extracting coffee in a sealed device prevents aroma loss. Hot water extraction at 90-95°C is followed by cooling inside the extractor. This prevents oxidation and loss of volatile compounds. The cooled coffee is then packed. The apparatus has a sealed housing, filter, coolers, and filling unit. An aroma recovery unit connects the housing and transfer pipe.

Beverage capsule that is biodegradable and environmentally friendly. The capsule uses a polysaccharide capsule body coated with polyvinyl alcohol and a polysaccharide layer. The coating layers provide gas barrier and water resistance. The capsule can be filled with beverage powder like coffee, tea, cocoa. It is suitable for beverage preparation by introducing water into the capsule.

Coffee maker that produces flavorful coffee using rapid extractions and multiple extractions from a single set of grinds. The coffee maker has a chamber with a piston and valve that allows pressure differential brewing. The chamber has multiple extraction zones with separate valves and tubes. The piston pushes water into one zone for an initial extraction, then moves to another zone for a second extraction. This allows multiple extractions using less coffee grinds compared to traditional brewing. The rapid extractions reduce bitterness and produce more flavorful coffee.

A capsule for making Turkish coffee in a standard coffee machine. The capsule contains coffee grounds and has a thin retaining wall with openings that break when pressure rises during brewing. The openings are non-linear shapes surrounded by linear elements. This allows the capsule to be used with a regular coffee machine that injects pressurized water. The Turkish coffee is made by the combination of the thin retaining wall that opens with pressure and the coffee grounds inside. The result is a coffee that has the characteristic dark crema and fine sediment particles like traditional Turkish coffee.

A coffee capsule with a separate water capsule containing water and a hole to release it into a coffee machine. This avoids using machine water for coffee and allows using bottled water. The capsules insert together into a machine and the perforator punctures the coffee capsule first before the water capsule releases water. This keeps the coffee contained while the water flows out.

A coffee capsule that allows a machine to produce a coffee beverage with taste and body similar to filter coffee. The capsule contains roast and ground coffee plus soluble coffee. By having a majority of roast and ground coffee and arranging it closer to the outlet side of the capsule, the capsule can be brewed at higher pressure without clogging.

Method for preparing coffee extract using low-temperature, low-pressure extraction that produces coffee extract with excellent flavor and aroma in high yield. The method involves grinding coffee beans into two sizes - coarse (10-20 mesh) and fine (20-40 mesh) - and adding them in specific ratios to an extraction column. Hot water is added and allowed to stand before extracting. This sequence prevents clogging and allows stable extraction at lower temperatures and pressures. The coarse grind at the bottom prevents clogs, the fine grind on top allows flavor, and the mix in between balances yield.

Coffee extraction apparatus and method that aims to extract coffee with better flavor and consistency compared to traditional methods like espresso and brewing. The apparatus has two extraction units stacked on top of each other. The top unit has a larger filter hole and higher pressure extraction. The bottom unit has a smaller filter hole and lower pressure. Coffee is first extracted in the top unit, then gravity feeds into the bottom unit for further extraction. This two-stage process allows extracting different coffee fractions optimally. The larger top filter lets through more oils and larger particles, while the smaller bottom filter captures finer particles.

Preparing coffee-based drinks using a beverage cartridge with finer grind coffee and lower extraction temperature compared to conventional coffee pods. The method involves extracting finely ground coffee (Helos D50 less than or equal to 200 microns) at lower temperatures around 90°C instead of boiling water. This allows brewing coffee without preheating the water, reducing energy consumption. The finer grind allows extraction at lower temperatures due to better contact between water and coffee particles. The lower extraction temperature prevents bitterness and preserves flavor compounds compared to boiling water extraction. The resulting beverage has good taste and aroma with lower bitterness.
