A method and equipment for extracting dissolvable solids from small particles using a staged, counter-current battery of centrifuges is described. The advantages gained by working with particles having a mean diameter smaller than 50 microns and doing the extraction with the particles dispersed in a non-flowing liquid are (1) a significant reduction in the concentration gradient of the dissolvable solids across the diameter of the particles and throughout the body of particles being extracted in a comparable standard column battery and (2) higher overall yields because extraction can be conducted to a uniform limit rather than being constrained by a local (surface or column position) limit. As regards coffee extraction, the equipment and method are intended for the production of high quality concentrated coffee extracts rather than the production of soluble or instant coffee.

An upward flow extraction method, apparatus, and extract are disclosed. The upward flow extraction method can comprise loading extraction material into an extraction cell having a bottom portion and a top portion; introducing a first aliquot of extraction medium through the bottom portion of the extraction cell; expelling gas from the extraction cell through the top portion of the extraction cell; closing the top portion of the extraction cell and increasing the pressure in the extraction cell as extraction medium flows into the bottom portion of the extraction cell; stopping the flow of extraction medium into the extraction cell; steeping the extraction material in the extraction medium under pressure to produce an extract; and introducing a second aliquot of extraction medium through the bottom portion of the extraction cell to push extract through top portion of the extraction cell.

Apparatus for distributing a solid, gel, powder, granular, liquid or viscous liquid test substance in an extraction fluid comprises: a) a flow cell for holding the test substance comprising an extraction chamber of uniform cross-sectional area, a grinding surface, an extraction fluid inlet and an extract outlet; b) a grinding head disposed within the extraction chamber and adapted to reciprocate therein; and c) a recirculating pump for driving extraction fluid: (i) into the flow cell via the extraction fluid inlet; (ii) through the extraction chamber; and (iii) back to the flow cell via the extract outlet.

An apparatus and method for brewing coffee of higher quality and better taste than any apparatus and method currently available, while also enabling users to utilize less coffee grounds per brewing cycle, thereby achieving significant cost savings for users. A basket that houses a packet of coffee grounds is housed within a carafe that stores water. The basket is fabricated so that water may enter therein and exit therefrom, and the packet of coffee grounds enables water and natural coffee oils to penetrate the packet, but does not allow coffee grounds to escape the packet. The carafe is filled with water that is gradually heated from at or around tap temperature to approximately boiling. While the water in the chamber is heated, the basket is agitated. This causes the gradually heating water to enter the basket and agitate the packet, thereby extracting natural coffee oil from the grounds stored within the packet, which creates brewed coffee. The entire brewing process may be controlled by electronic controlling means.

The present invention relates to a Turkish coffee cooking and serving machine having a cooking compartment whose inner volume is heated by a heater and wherein coffee mixture including Turkish coffee, water and optionally sugar is cooked; and when the cooking process is completed, providing transfer of the cooked coffee mixture in the cooking compartment through a discharge spout to a beverage receptacle for serving the cooked coffee to people.

An apparatus for brewing coffee in a pre-existing vessel includes a frame, a basket, a means for agitating the basket and a power source. The basket includes at least one opening that is capable of permitting liquid to transgress into and out of the basket. The power source provides the necessary power for operating the motor. The motor is attached to the frame and a linkage connects the motor to the basket. The means for agitating the basket imparts motion to the basket during operation. The apparatus may further include an on-board heat source.

A beverage extraction device includes a mesh member, a cover member that is movable between a first position and a second position; a scraper portion, an upper end portion of which is pivotally supported by the cover member with a lower end portion of the scraper portion being swingable along a vertical direction, that takes a basic attitude in which the lower end portion is positioned lower than the upper end portion under a normal condition, the lower end portion being configured to slide on the mesh member when the cover member is moved from the first position toward the second position; and a contact member configured to come into contact with the scraper portion sliding on the mesh member to cause the scraper portion to take an attitude in which the lower end portion swings upward when the cover member approaches the second position.
