Aroma Enhancement in Coffee Pod Brewing

A professional espresso coffee machine that dynamically regulates water flow rate during brewing to improve coffee quality and customization. The machine, called DFC (Dynamic Flow Control), regulates water flow rate based on coffee characteristics to adapt to variable conditions. It does not impose a fixed water flow rate throughout brewing. Instead, it modifies the flow rate profile to match coffee resistance. This allows repeatable, customizable brewing without compromising water pressure. The machine has steps of pre-brewing, pressurization, and brewing. The flow rate is initially high, then stabilizes as pressure builds, then drops as water passes through the coffee. By adjusting flow rate based on coffee characteristics, it improves extraction and repeatability.

Quantity control device for brewing coffee with customizable extraction parameters. It allows extracting coffee beans using different water quantities and pressures to create custom flavors and aromas. The device has separate cold and hot water lines with solenoid valves and ball valves to control water flow. It also has a pump, return lines, and a flow control valve. To brew coffee, cold water is supplied through the ball valve. For hot water, hot water is pumped and returned. This allows adjusting extraction parameters like water volume and pressure. The flow control valve stabilizes hot water pressure. The return lines circulate water for cleaning.

Coffee brewing flow control method and brewer that stabilizes water flow rate during brewing for consistent coffee quality. A flow meter detects real-time water flow, which is sent to a controller. The controller adjusts the gear pump speed to maintain stable water flow into the brewer. This links the flow meter and pump for real-time regulation of water flow. The brewer also includes a safety valve to prevent overpressure.

Coffee machine water system that allows adjustable pre-soaking time and pressure for better coffee extraction. The system has parallel water and supply water paths connecting the tank and brewer. The water path includes a low-pressure pump for pre-soaking. The supply path has a higher pressure pump. This lets brewing start with low pressure for pre-soaking then switch to higher pressure for extraction. The parallel paths provide flexibility to customize the extraction process.

Device for stable and effective coffee extraction with adjustable pressure and flow control. It uses two electromagnetic pumps, a water tank, pressure relief valves, and a flow meter to maintain consistent water flow during extraction. The pumps provide continuous output to prevent flow instability caused by single pump pressure regulation. A central processor determines the needed pump frequency based on target extraction pressure and adjusts accordingly. This ensures sufficient flow rate and extraction stability.

Coffee machine that maintains consistent brewing pressure to improve coffee taste. The machine has a flow meter on the water outlet pipe that measures the water flow. A processor analyzes the flow data to determine the brewing pressure. This allows adjusting the water flow rate to compensate for factors like coffee powder amount and thickness that affect resistance. By controlling the brewing pressure, it aims to provide more consistent coffee taste compared to relying solely on pump output.

Pressure-controlled coffee extraction system and method that allows stable and precise coffee extraction water pressure without additional waste water drainage. The system uses two water pumps that operate in staggered phases to jointly supply water to the extraction component. A control circuit drives the pumps to cross zero and work out of phase. This allows adjusting the water pressure by controlling the pumps based on detected pressure vs preset target. This prevents pressure spikes and instability compared to single pump systems.

A small manual coffee maker with a detachable cup body and brewing base that allows brewing one cup at a time. The coffee maker has separate water, coffee, and pressure chambers. Water is filled into the water chamber through an inlet valve, which allows one-way flow into the pressure chamber. The pressure chamber pushes water into the coffee chamber through an outlet valve. The cup body also has a piston rod that extends into the pressure chamber. The detachable design allows brewing directly into a cup, and the separate chambers prevent over-extraction.

Coffee machine that improves the aroma and flavor of espresso by pressurizing the water in two stages to extract the coffee at the optimal pressure. The machine has a water supply circuit with a pump, valve, flow meter, and pressure sensor. The pump pressurizes the water in one step. The valve controls the flow rate. An actuator pressurizes the water further in a second step. The electronic controller adjusts the valve and actuator based on user settings and sensor readings to reach the desired extraction pressure. This two-stage pressurization improves coffee quality by avoiding under-extraction issues when using a single pump.

A system for reproducing the brewing state of a coffee machine using sensors, wireless communication, and computer control. The system digitizes and displays brewing parameters like pressure, flow rate, and temperature. It allows recording, reviewing, and sharing brewing data. Closed-loop control lets adjusting pressure or flow rate targets automatically adjust pump power. The system also reproduces brewing curves using priority or adaptive modes based on recorded data.

A coffee extraction system that allows for both constant pressure and variable pressure brewing. The system uses a heating chamber with a pump, three-way valve, and pressure limiting valve. The pump pumps water into the chamber to extract coffee. The three-way valve connects the chamber to the brewer or waste container. The pressure limiting valve prevents overpressure. A sensor detects chamber pressure. During extraction, if pressure rises too high, the pump voltage/frequency is adjusted to lower pressure. After extraction, if pressure is too high, the three-way valve is switched to release pressure. If pressure is too low, the three-way valve is closed and pump starts to raise pressure. This allows consistent extraction at lower pressures and variable extraction at higher pressures.

A coffee machine water system that allows flexible and stable water pressure during brewing to improve coffee extraction quality. The system has separate pumps with different maximum pressures and flow rates for pre-soaking and extraction stages. This enables customizing the water pressure and time for pre-soaking to prevent channeling effects. During extraction, the pump with lower flow rate but higher pressure maintains stable pressure for consistent extraction.

A two-stage water volume coffee brewing device with separate flow control for extracting coffee aroma substances in advance to improve coffee layering and avoid bitterness. The device has a boiler connected to a pipeline with two parallel branches. Two sets of control structures, one for initial extraction and one for post-extraction, are installed on the branches. During brewing, initially only the first set is open while the second is closed. Then, at the end, the second set is opened while the first is closed. This allows selective flow control to accurately extract coffee in stages.

A coffee brewing machine that consistently delivers coffee with optimal flavor by regulating water pressure and temperature during brewing. The machine has separate heating elements in the water reservoir and brewing chamber, along with pressure sensors. A control unit monitors the water pressure during brewing and adjusts the heating power in each section based on the counter-pressure from the coffee grounds. This maintains consistent water temperature and pressure through the brewing process for consistent flavor.

The machine has separate in-line heaters to rapidly change the temperature of the water instead of relying on a fixed-temperature boiler. A syringe pump controls pressure. Sensors monitor temperatures at each heating element. Electronic modules estimate flow rate based on temperatures and adjust power to the final heater to compensate. This allows precise temperature profiling during extraction by directly controlling the flow rate. It provides better control than traditional machines with fixed pressure pumps and boilers.
