摘要:
In a post-mix beverage dispenser system including beverage concentrate containers and a storage tank for the supply of diluent through an electromagnetically actuated valve, the beverage concentrate is provided to the mixing station in a series of individual pulsed portions by a reciprocating piston pump coupled to the containers for the beverage concentrate. An electromechanical control circuit is also provided for rhythmically opening and closing the electromagnetic valve for a pulsed supply of diluent in synchronism with the pulsed delivery of the beverage concentrate for providing a mixture of precise proportions.

Apparatus for supplying water to a carbonator tank in a liquid dispensing system includes a water supply delivery control circuit which generates a periodic supply enabling signal of a relatively short duration when the water level in the tank falls below a predetermined level and an enabling signal of a comparatively longer duration when an initial filling of the tank is desired or a system reset switch is manually activated. Both periods are selected so as to prevent damage to the delivery pump, for example, due to an overload condition caused by an interruption of the water supply.

A method for roasting coffee beans in a roasting chamber, which includes depositing a quantity of coffee beans in the roasting chamber being small in proportion to the volume of the roasting chamber, directing a heatable air current through the roasting chamber substantially vertically from the bottom upward for rotating, upwardly whirling and circulating the coffee beans in a freely suspended state substantially untouched by each other and by the roasting chamber, and a device for carrying out the method.
摘要:
An electromagnetic assembly including an electromagnetic coil wound on a core of ferromagnetically conductive material. A temperature protection circuit includes a fuse which breaks when the electromagnetic assembly becomes overheated. The fuse is thermally coupled to pole pieces of the assembly and is in electrical circuit with the coil.
摘要:
A circulation pump system in a storage vessel for liquids, more particularly in a carbonizing tank of a beverage dispenser in which soda water, a mixture of CO.sub.2 gas and fresh water, is chilled and stored under pressure for withdrawal via an outlet connection. The circulation pump is mounted directly above the discharge port of the storage vessel so that the small amount of heat released by the circulation pump is utilized to keep the outlet opening free of ice.
摘要:
A water-carbonation system having a pressurized tank which is preferably cooled, a water supply and a CO.sub.2 gas supply. The CO.sub.2 gas supply has a pressure-reducing valve assembly in the supply line. The valve of this assembly is maintained in a closed position by the gas pressure in the tank. However, when this pressure falls below a predetermined limit, the valve will move to an open position to vent the tank to the atmosphere. A signal may be used in conjunction with the valve to notify an operator of the drop in pressure. The valve may also be manually operated to vent the tank. This water-carbonation system can be used in beverage dispensers in which the carbonized water is mixed with beverage concentrates to prepare a beverage that is ready for consumption.
摘要:
A carbonator tank in a post-mix beverage dispenser is provided with an electrically powered circulating pump. The pump is mounted in an opening in the bottom of the tank and includes a flow-through channel for dispensing carbonated liquid from the tank through the housing of the pump. The tank includes a cooling coil for forming an ice bank around the interior walls. The heat generated by the pump motor precludes the freezing of the carbonated water in the flow-through channel.
摘要:
A circuit configuration for regulating the filling and refilling of containers with liquids, such as a carbonator vessel, and comprises a liquid container and an electronic circuit for reading the liquid level in the container at a single level and generating a level signal corresponding to the liquid level sensed, and in the event the level falls below a predetermined level, causes a flow regulator controlled by a timer to provide a refilling with an overshoot so as to permit the liquid level to rise to a second predetermined level above the first predetermined level so that the volume of the head space and pressure within the container is held substantially constant.
摘要:
Automatic household beverage dispenser including an equipment cabinet having a front and defining a mixing space with a dispensing station and an equipment space formed therein, detachable and replaceable functional parts including supply tanks for beverage concentrate and a device for dispensing carbon dioxide, electrical and flow devices for proportionate dispensing of concentrate, forming a mixture of concentrate and water and conducting the mixture to the dispensing station, the equipment space having a coverable opening formed at the front of the equipment cabinet for removal and replacement of all of the functional parts.
摘要:
An assembly, especially for a beverage-vending machine with a container for the storing, cooling and carbonating of water including two measuring electrodes arranged in the container at differing horizontal and vertical distances from an electrically conductive inner wall of the container connected to ground, one of these in the area of the ice layer under formation. The measuring electrodes obtain resistance values for the ice and/or water that arise between the electrode and the inner wall of the container. In order to cool the water independently from its physical-chemical composition, potentials corresponding to the resistances are derived and are supplied to a differential amplifier. Depending on a size comparison of the two resistance values, a cooling apparatus that affects the contents of the container is switched on or off.
