Abstract
Procedure and machine for preparing hot drinks starting from a tank of water at atmospheric pressure that allows fine adjustment of the infusion and extraction parameters, as well as automatic or manual management thereof, by way of at least one control unit, with selection being allowed by way of a rotary coder with a button function, the machine being equipped with a single rotary pump controlled by way of a pulse-width modulation circuit and with wireless communication means. The machine is destined for the industrial sector of manufacturing machines for preparing hot drinks.
Claims2
A machine for preparing hot drinks for which it is possible to measure and to adjust parameters of pressure, time, and temperature that are needed in the phases of infusion and extraction, wherein said machine has a single DC motorized rotary pump regulated by a pulse width modulation circuit for which the water supply at atmospheric pressure is provided from a tank, the upper portion of which is open, and which has means of ensuring its water level by means of a capacitive water level sensor and by the supplemental operation of an electric valve connected to the supply mains;
- and in that it has at least one flow meter situated between the tank and the boiler with heating element, a pressure transducer downstream from the pump, a check valve and a dispensing assembly with an actuator, in that it has a control unit to enter the type of beverage being prepared, and for allowing a variation of the parameters for preparing the beverage and recording these for future use in at least one memory, these means of selection being embodied by a rotary encoder with push-button function and a graphics display interface having a conventional keypad;
- the machine comprises means of communication such as a USB port and/or wireless means such as WiFi or Bluetooth.
