Abstract: A drain tray for a solenoid valve of a machine for coffee dispensing includes a base portion that defines a collection cavity for at least one fluid coming from the machine. The drain tray includes a cover portion that defines a cover cavity which, together with the collection cavity of the base portion, defines a respective compartment. The drain tray includes at least one inlet connectable to the solenoid valve of the machine for the transit of a respective hot waste fluid towards the compartment. The drain tray includes an outlet for the outflow of at least one fluid coming from the machine accumulated inside the collection cavity of the base portion. The drain tray includes a heat exchanger, arranged inside the compartment having at least one coil arranged to remain at least partially immersed in the fluid of the solenoid valve of the machine.

Abstract: Filter holder for espresso coffee machines having a cup-shaped body of circular profile, suitable for internally housing the filter, as well as a pouring device of the beverage disposed under the cup-shaped body and provided with at least one pouring spout, the filter holder being provided with connections for connecting the pouring device to the cup-shaped body, wherein the connections enable a bayonet coupling between the pouring device and the cup-shaped body.

Abstract: Coffee machine having a water system in which pressurized hot water circulates, at least one dispensing unit fed with pressurized hot water, a first filter holder housing a first filter for the preparation of espresso coffee, a second filter for the preparation of American coffee, having a funnel-shaped basket which with an upper collar with a cylindrical shape, which is inferiorly joined with a conical hopper perforated with a plurality of holes.

Abstract: A steam production system for professional coffee machines includes a nozzle; a boiler for producing steam in flow communication with a water source and the nozzle. The boiler is equipped with an independent heating device for the initial production of steam. The system further includes a heating assembly to instantaneously produce steam in flow communication with the boiler and/or the nozzle. The heating assembly includes an electric heating element; a heat exchanger associated with the electric heating element; and a water passage circuit associated with the heat exchanger which has an inlet joined to a water supply source or to a duct arriving from the latter and an outlet of the produced steam connected to the boiler and/or to the nozzle. The system also includes a programmable electronic unit operatively connected to the boiler and to the heating assembly to ensure the supply of steam to the nozzle.

Abstract: A set includes a plurality of coffee grinders, each coffee grinder including: a body, a grinding unit, actuation means to activate the grinding unit, a load cell to weigh a filter holder, and booking means to book the activation of the coffee grinder; the set has a central control unit to receive a booking signal from the booking means of each coffee grinder and create an ordered list with an activation sequence of the coffee grinders; the central control unit is connected to the load cell of all coffee grinders to send an activation command of the load cell to a coffee grinder at a time according to the sequence indicated by the ordered list.

Abstract: A coffee machine including a main body including a circuit for dispensing coffee having an inlet that can be hydraulically connected to a water supply line; a central processing and control unit configured to control at least the circuit for dispensing coffee; a communication interface configured to connect with a telecommunications network; a sensor system for the detection of parameters related to possible operation anomalies or failures of the coffee machine provided inside the main body; a peripheral processing unit at least connected to the sensor system and configured to carry out a first local processing of the data detected by the sensors and to send the locally processed data to one or more remote server by the communication interface.
