Embodiments of the present disclosure include a matrix of raw materials that 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. 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.

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.

A method and apparatus for extracting compounds from raw materials with an extraction column is provided. The control and manipulation of pressure exerted 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 method may include directing a flow of pressurized solvent into a base of the extraction column and utilizing the flow of pressurized solvent to create a pressure gradient applied to the raw materials. The method may further include compressing the raw materials with hydraulic compression. As the raw materials become further compressed, frictional heating may result allowing most, if not all, of the volatile aromatic heat sensitive compounds and constituencies to be extracted depending on the pressure strength applied to the raw materials. As such, manipulating the pressure gradients for each extraction process allows for distinct and specific flavor profiles to be extracted from the raw materials.

An infusion chamber has a top perimeter cover that defmes an aperture to pass air to an air vent and receive fluid from fluid outlets. The infusion chamber has an outer chamber and an inner chamber positioned within the outer chamber, where the spacing between the outer chamber and the inner chamber defmes a void. An air manifold is positioned at the base of the inner chamber. The air manifold includes air inlet channels, air exit channels and an interior solids filter. The infusion chamber also has a base housing positioned at the bottom of the infusion chamber, and a plunger positioned in the base housing to selectively evict liquid from the inner chamber.

The present disclosure relates to a spray head assembly for a beverage making machine comprising a mounting for connection to a flow of liquid from a reservoir or other water source and a surface for joining to a spray head. A face portion of the spray head has an interior surface with relative rises and depressions or hills and valleys. Orifices are located generally at the peak of a hill with valleys being defined between neighboring hills.

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.

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.

A beverage machine that includes a brewing chamber; and a dispensing spout for dispensing liquid into the brewing chamber, wherein the dispensing spout includes a liquid inlet; a main body having a central axis and at least a first liquid outlet and a second liquid outlet, wherein the second liquid outlet has a larger distance from the central axis than the first liquid outlet; a liquid distributor fluidly connecting the liquid inlet selectively to the first liquid outlet or to the second liquid outlet, and an actuator for changing a position of the liquid distributor relative to the main body between at least a first position, wherein the liquid inlet is fluidly connected to the first liquid outlet and a second position, wherein the liquid inlet is fluidly connected to the second liquid outlet.

A coffee machine includes a device for supplying hot water to an outlet device into which a filter-paper insert with ground coffee is insertable. The outlet device is adapted for being arranged above a filter vessel and for receiving the hot water from the hot water supply. The outlet device has a central outlet opening over a middle region of the filter-paper insert when filled with ground coffee and a plurality of outer outlet openings arranged above a middle region of the side walls of the filled filter-paper insert. A controllable selector switch controls a rate of hot water through individual outlet openings of the outlet device. The controllable selector switch has at least three switching positions for adjusting coffee strength. In all switching positions of the controllable selector switch the hot water is at least partially supplied via the outer outlet openings over the filled filter-paper insert.

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.
