Abstract
A machine to prepare beverages includes at least one tank for the water fluidically connected to a filtering container suitable to contain an aromatic mixture; a pump to feed the water from said tank; a heating device to heat the water in transit; and a control and command unit connected to a user interface. The invention also concerns a method to prepare beverages.
Claims15
A machine to prepare beverages comprising at least one tank for the water, fluidly connected to a filtering container suitable to contain an aromatic mixture;
- a pump to feed water from said tank;
- a heating device to heat the water in transit;
- temperature sensors to detect the temperature of the heated water and a control and command unit connected to a user interface, comprising boiling temperature indicator means configured to monitor in real time the growth curve of the temperature of the water for preparing the beverage, and to provide said control and command unit with information on an actual water boiling temperature value, and said control and command unit is configured to regulate at least the functioning of the heating device as a function of the heating speed and of said actual water boiling temperature value, correlated to an ambient pressure surrounding the machine itself, so that the temperature of the water for preparing the beverage remains below a safety temperature value lower than said actual boiling temperature value.
The machine as in an ambient pressure measurement device configured to communicate an ambient pressure value to said control and command unit, and said control and command unit is configured to convert said pressure value into a water boiling temperature by means of tables and/or graphs, to determine a safety temperature of the water for preparing the beverage.
A method to prepare a beverage in a machine for preparing beverages comprising a tank, fluidly connected to a filtering container suitable to contain an aromatic mixture, wherein the method provides to:
- receive at entry in a control and command unit a command relating to the type and organoleptic characteristics of a beverage selected by the user by means of a user interface;
- determine the operating parameters for a pump and a heating device to regulate the water temperature and flow rate as a function of the selected beverage;
- and
- detecting the temperature of the water for preparing the beverage using sensors, to monitor in real time the growth curve of the temperature of the water for preparing a beverage, and to regulate at least the functioning of the heating device as a function of said growth curve and an actual boiling temperature value of the water, correlated to an ambient pressure surrounding the machine itself, so that the temperature of the water for preparing the beverage remains below a safety temperature value lower than said boiling temperature value.
