Title:
METHOD AND SYSTEM FOR BREWING INGREDIENTS IN A SOLVENT, APPARATUS USING SAID SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/085813
Kind Code:
A3
Abstract:
The invention relates to a method and a system (1) for brewing ingredients in a solvent, said system comprising: -a first unit (5) for measuring a change of the electro-conductivity (ΔEC) of said solvent, -a second unit (6) for comparing said change of the electro-conductivity (ΔEC) with a predetermined threshold (TH), to generate a signal (S) indicating that the ingredients should be separated from the solvent. This system allows determining when the brewing of ingredients has to be stopped, without the need for a user to have a preset brewing time duration.
