A device for preparing coffee by manual brewing includes: a filter holder for receiving a filter insert with ground coffee; a holder in which the filter holder is inserted; a vessel arranged under the filter holder into which the brewed coffee can be filled; a drain arranged on the filter holder; and a closure element arranged on the drain for opening and closing the drain. An actuating element for the closure element is provided on the filter holder by which the closure element can be moved between an open position and a closed position independently of the vessel.

The disclosure herein relates to a portable capsule percolator with a drinking cup. In particular, the disclosure relates to a portable and easy to use capsule percolator, operable, using capsules readily available on the market, for making a desired percolated beverage such as coffee, tea, vegetarian drinks and the like, on the go, at the office, while travelling and more specifically, whenever or wherever such a drink is desired. The portable capsule percolator is operable by a pressure differential mechanism without the need of a power source. The portable capsule percolator includes an air-extracting mechanism operable to extract air from a first internal space and a sealing mechanism associated with the flask lid section configured to let outside air into a second internal space generating the pressure differential, activating the percolating process by pushing the liquid through a beverage capsule into a percolating section.

A method and a system are disclosed for managing a brewing process in which a solution is produced by mixing a solvent with a solute and a beverage is extracted from the solution. The system includes a temperature sensor device for sensing a temperature change per unit time of the solvent to create temperature information; a first measurement device for sensing a weight increase per unit time of the beverage to create first weight information while counting the time elapsed in the brewing process to create timing information; and a computing device comparing preset standard-state information with the temperature, first weight and timing information. A warning message is displayed on the computing device to remind a brewing operator to stop brewing the beverage when any of the temperature, first weight and timing information created at a specific unit time does not match the standard-state information of the same unit time.

A method for examining beverage brewing and extracting process includes the steps of adding a solvent to a solute, mixing the solvent and the solute together to produce a solution, and subjecting the solution to an extraction process to output an extract liquid; measuring a solvent weight increase per unit time of the added solvent and measuring an extract liquid weight increase per unit time of the output extract liquid at the same time during the step of adding the solvent to the solute; and performing a calculation on the solvent weight increase and the extract liquid weight increase to output a graphic data to represent the extraction process. By referring to the graphic data, even an inexperienced brewing operator can always ensure a consistent taste for the brewed solution.

The present invention relates to a method for extracting Dutch coffee and an apparatus thereof, and more particularly, to a method for extracting Dutch coffee, which can exactly control a speed of extraction of Dutch coffee and an amount of coffee to be extracted by supplying water during a predetermined time repeatedly at regular time intervals in each step, can always provide Dutch coffee of a constant concentration to consumers by uniformly distributing water to a filtering container, and can provide a rich aroma of Dutch coffee by collecting the aroma of Dutch coffee not to dissipate, and an apparatus thereof. The method for extracting Dutch coffee controls an amount of extracted coffee by setting an opening time of a valve mounted between a water tank and a filtering container, controls a speed of extraction by setting one cycle length, and mechanically controls a total speed of extraction by setting a total time, and the Dutch coffee extraction apparatus includes: an upper main body frame; a lower main body frame which is formed on a lower portion of the upper main body frame and has a width shorter than that of the upper main body frame; a side frame which connects the upper main body frame and the lower main body frame with each other; a water tank which is disposed inside the upper main body frame and has a cover provided on an upper portion thereof to store water therein; a filtering container which is disposed at both sides of the lower main body frame, is connected with the water tank via a nozzle to receive water from the water tank, and stores ground coffee thereon; an extracted liquid storage container which is disposed under the filtering container to store an extracted liquid thereon; and a digital operation unit which is formed on one side of the side frame.
