Device for heating and working up milk
First Claim
1. A device for heating and working up milk for preparing cappuccinos on a coffee machine, comprising:
- a steam generating boiler;
conveyor means equipped with an open submergible end, wherein said submergible end can be submerged in a vessel containing milk;
a first pipe for supplying steam, connected between said boiler and said conveyor means;
a shut-off member;
pressurized air source;
a second pipe for supplying pressurized air, connected between said pressurized air source and said conveyor means;
a temperature sensor associated with said submergible end of the conveyor means to detect the temperature of the milk in said vessel;
a control unit connected to the shut-off member, to the pressurized air source as well as to the sensor, which is sensitive to the temperature of the milk, said control unit being programmable to control the open and close of said shut-off member and to actuate said pressurized air source, one independently from the other, according to the desired temperature and/or working up for the milk.
