Description

BEVERAGE DISPENSER WITH
SELECTABLE BEVERAGE SENSORY PARAMETERS
Field of the invention
The present invention relates to a beverage dispenser for preparing beverages - in particular coffee - according to a choice of the consumer based on the beverage sensory profile.
Background of the invention
The invention particularly relates to beverage dispensers preparing coffee based beverages from a soluble coffee product. This soluble coffee product is diluted with a diluent usually hot water. The dilution can be operated in a dilution or mixing chamber and, depending on the nature of the beverage ordered by the consumer, the mixture of the coffee product and the diluent can be whipped to create foam at the top of the beverage.
These dispensers generally present a user interface proposing to the consumer a choice of different coffee based beverages types like espresso, coffee with milk, American coffee, cappuccino, macchiato, ... The interface also usually enables to select the sugar intensity, the temperature or the volume of the beverage. Usually the coffee based beverages types have been market tested and the recipes for their preparation are set in a memory on which the control unit of the dispenser relies. Consequently, the consumers can only get a limited choice of beverages in the dispenser. Then there is a need for a dispenser that could propose to the consumers beverages different from those initially set in the dispenser and that could enable the consumers to define their own beverages according to their own taste.
US 2006/0188620 describes a system for making and delivering a customized coffee beverage in which the customer can select the size, the colour, the strength, the temperature of the coffee and the introduction of additional flavours. The control of the strength of the coffee is made by utilization of delayed dilution, delayed mixing and/or delayed filtering of coffee extracts issued from roast and ground coffee brewing. Liquid extracts of different strengths are produced and can then be mixed so as to reach the strength desired by the customer.
In the field of beverage dispensers preparing beverages from soluble ingredients, WO 2009/032877 describes a juices based beverages dispenser in which the consumer can select the nature of the different components of her/his beverage and the ratio of these selected components. This process enables the consumer to invent her/his own recipe. Due to the fact that the consumer knows exactly the taste of different juice flavours (apple, orange, ...) she/he can guess what the resulting mixture will taste. In the field of beverage dispensers preparing beverages from a soluble coffee product, there is not such a large choices of flavours with which the consumer can play. Actually the coffee dispensers generally comprise two sources of coffee ingredient : a soluble coffee powder and a soluble decaffeinated coffee powder. In such coffee dispensers, there is a need to propose to consumers to change the beverages recipes initially set in the dispenser so that the consumer can get the coffee beverage he likes in terms of coffee sensory profile not only in terms of the strength and colour of the coffee beverage, but also in terms the quality of the crema at the top of the coffee beverage, of the aroma and of the taste of the coffee beverage.
The aim of the present invention is to propose a coffee based beverage dispenser preparing beverage from coffee soluble ingredients which prepare the beverage according to a sensory profile defined by the consumer.
It has also been observed that the taste of consumers varies from one world area to another : European consumers do not drink their coffee like American. Asian consumers like their coffee in another third way too. Yet the same beverage dispenser is generally produced for being sold and used in every part of the world. If the dispenser is set for a European consumer taste, it won't answer the demand of the consumers of the rest of the world and won't have success there.
Besides the beverage dispensers produced by the dispensers' manufacturers are usually sold to customers or operators who manage the operation of the dispensers. These operators usually want all their dispensers to deliver the same type of beverages, in particular presenting the same taste, so as to develop consumers' loyalty. Yet again the same beverage dispenser is generally produced for being sold to all operators. If the dispenser is set for one operator taste, it won't answer the demand of the other operators.
Therefore there is need for manufacturing dispensers that can be individually set for answering all the expectations of the consumers or the operators.
In particular there is a need for a dispenser that incorporates usual components for making a beverage but that can be set for providing beverages according to the consumer or the operator taste. Summary of the invention
