A method of processing roasted coffee to improve the retention of carbon dioxide and aromatics liberated from the roasted coffee. The method involves preparing one or more containers for receiving coffee. The containers are purged of contained air through flushing with an inert gas. Roasted coffee is transported and delivered to a grinding circuit where it is ground directly into a container filling apparatus. The container filling filling apparatus delivers the ground coffee directly into the purged containers after which the containers are sealed to maximize the retention of carbon dioxide and aromatics liberated from the roasted coffee and to minimize contact of the ground roasted coffee with the air.

Disclosed is a single-serve capsule for improved extraction efficiency and flavor retention. Extraction efficiency is improved by using ground roast coffee having an average particle size in the range of from 300 to 800 μm. Flavor retention is improved by using a filter medium made of a synthetic polymer. The capsule can be used in a process in which optimum extraction is obtained during relatively short brew times.

A method for delivering a long coffee extract from a capsule containing ground coffee within a flow time of 50 seconds or less by injection of water under pressure within the capsule. The capsule is filled with ground coffee and has a delivery membrane. The capsule is extracted in a coffee extraction device, and pressurized water is injected in the capsule under pressure. The coffee beverage is released through the beverage delivery membrane of the capsule with engaging means engaging in and / or against the membrane. The pressure loss is reduced in the coffee bed by providing in the capsule coffee ground having a controlled percentage of fines (F) depending on the average particle size (D4,3). The flow time can be lowered to 40 seconds or even less while maintaining a coffee extraction yield within a high range of 15 to 30%.

Automatic process for calibrating the single and double dose of ground and dispensed coffee by means of a specific grinder-doser integrating a weighing device with a load cell. The process is automatically and steadily carried out during the ordinary activity, with no interruptions, adapting the grinding time according to the actually detected grammages, in order to get closer as much as possible to the desired grammage in any use condition. The process, after a preliminary phase for temporary configuring the desired grammages and the grinding time, conceives self-calibration cycles continuously repeated, each of them comprising three sequential phases: a first phase for automatically checking the dispensing with progressive weight detections, a second phase for automatically processing the detected data for determining the correct grinding time, a following third phase for the automatic setting.

The present invention relates to a method of producing an extract of green coffee wherein green coffee beans are subjected to a heat treatment and extracted without being roasted.

A method for processing coffee beans (C), including the step of charging the coffee beans (C) in a vessel (10) and supplying water inside a vessel body (11) by spraying out water inside the vessel body (11) through an injection liquid charging channel (23) via a spray nozzle (23a) for allowing water to penetrate to the inside of the coffee beans (C) while the inside of the vessel body 11 is under pressure and heated, and the step of reducing the pressure inside the vessel body (11) for water having penetrated to the inside of the coffee beans (C) to expand by vaporization in grinding the coffee beans (C) that have been swollen in a porous manner using an expanding force.
