A coffee maker provides a controlled release of heated water into brewing material. In one embodiment the coffee maker includes a spiraling nozzle releasing heated water over brewing material held in the coffee maker. The nozzle provides a single release point at each instant providing improved exposure of the brewing material to the heated water. In another embodiment the coffee maker includes a rotating sprinkler arm releasing heated water into the brewing material. In either embodiment motion may be provided by the flow of heated water, or by an electric motor.

An apparatus and method are provided for extraction compounds from raw materials. The control and manipulation of heat formed and contained within the extraction vessel or column may be vital in obtaining a certain flavor profile or intensity of the effluent extracted from the raw materials. As such, the solvent entering the apparatus to extract the raw materials may be heated to a specified temperature range with the aid of energy already formed within the extraction column. The apparatus to extract the raw materials may include a body comprising a pressure vessel capable of withstanding high temperatures and pressures. Additionally, a flow of pressurized solvent may enter the base of the extraction column, where the flow of pressurized solvent has a select temperature such that the temperature may be manipulated to obtain a distinct flavor profile of the effluent extracted from the raw materials.

Embodiments of the present disclosure include a matrix of raw materials, also referred to as a poly-grain grind matrix. In some embodiments, the matrix of raw materials may form an interlocking network of varied particle grind sizes that allows the particles to nest and interlock with one another when packed into an extraction vessel, so that most, but not all of the interstitial spacing within the matrix of raw materials is closed. Additionally, the varied particle sizes may be selected by pre-determined weight ranges and size classifications so that the particle grind sizes achieve the desired consistency uniformity. This may allow the network of particles to act as its own best filtering agent during the extraction process. Moreover, the nesting and interlocking network of the particles within the matrix of raw materials may allow the particles to be effectively packed within the extraction column, thus allowing for an efficient and high quality extraction to be performed consistently each and every time.

A group head vortex shower is used in a coffee machine and includes a bottom wall, a surrounding wall and a reflection wall. The surrounding wall extends from the bottom wall, surrounds a central axis, cooperates with the bottom wall to define a water inlet space, and has a plurality of outer outlets that are in fluid communication with the water inlet space. The reflection wall is sleeved around the surrounding wall, and has at least one curved inner surface that surrounds the central axis. Each of the outer outlets outputs a water jet from the water inlet space in a water outlet direction towards the at least one curved inner surface of the reflection wall. An imaginary extension line of each of the outer outlets and the central axis are skew lines.

A sprayhead for a pour over coffee brewing machine for delivering hot water to coffee grounds held in a brew basket therebelow, has a housing with a water inlet at one end thereof, which is connectable to an intermittent source of hot water. A holding chamber for accumulating a quantity of hot water therein is located within the housing and is connected to the water inlet. A dispensing chamber is located within the housing and below the holding chamber, in use. A bell siphon located in the holding chamber delivers the accumulated quantity of water from the holding chamber to the dispensing chamber, and then to the coffee grounds, once the water level in the holding chamber rises above an open end of a siphon tube.

A system and method are provided for extracting compounds from raw materials packed into an extraction column. The system may include a flowing solvent source connected to an extraction column to provide a flow of solvent for extracting the raw materials. The system may also include an electrodeionizer to separate positive ions and negative ions within the flowing solvent to create an imbalance of ions and transform the solvent to a deionized solvent. In further embodiments, the extraction column includes a solvent surface layer in contact with a bed of raw materials, such that the hydraulic pressure applied within the extraction column results in the formation of catalyzing energy to generate a self-perpetuating energy cycle to extract the raw materials.

An automatic beverage system for producing a hot flavored beverage. The system includes a base unit having a water reservoir, a control system for heating liquid from the reservoir, a cartridge arm having a water injector and a cartridge holder, a pump and tubing system connecting the water reservoir to the cartridge holder and used to move water, the control system housed within the base unit and coupled to the heating element and pump to control temperature and movement of the liquid from the reservoir to the cartridge holder, and a container base positioned in an area adjacent the base unit and below the cartridge holder. The cartridge holder is adapted to receive interchangeable cartridges depending on the type and size of beverage desired. The beverage system is capable of using a beverage pod to dispense an individual cup of coffee or the like, and it is also capable of brewing larger volumes of coffee using freshly ground coffee beans. The heating element and related safety features ensure that the water is safely heated and maintained at an optimal brewing temperature.

An automatic machine for preparing infusion beverages has a housing and an infusion vessel inserted or insertable into the housing. The infusion vessel has a lower inner surface and a lateral inner surface, which together define an interior space serving to receive infusion material and water, as well as an outlet opening. For discharging the infusion beverage from the infusion vessel, an outlet conduit is connected or connectable to the outlet opening. An outlet valve is provided to open or close, the discharge of the infusion beverage through the outlet conduit. The automatic machine also has an inlet device for admitting a liquid into the infusion vessel, which is configured in such a way that the liquid flows uniformly over the lateral inner surface into the interior of the infusion vessel. A method for the automatic cleaning of an infusion vessel used for the preparation of an infusion beverage is also disclosed.

Apparatus and methods are provided for extracting compounds from raw materials. One such apparatus may include an extraction column where it is a one column, one pass design capable of withstanding high temperatures and pressure. Additionally, the extraction column may also be capable of containing a self-perpetuating energy cycle used to achieve the required solubilization and mass transfer temperatures necessary for optimal extraction. The apparatus may also include a first opening and a second opening to control the flow of incoming solvent and filter extraneous sediment trapped within the fully extracted effluent. Additionally, the apparatus may be configured to create a self-perpetuating and self-sustaining energy cycle by manipulating the pressure and temperature generated within the apparatus. While the generated temperatures may help achieve a dynamic and efficient extraction process, a trailing cool layer of solvent is also present to effectively preserve the heat sensitive compounds extracted from the raw materials.
