Patent number: 11702331Abstract: A beverage dispensing machine includes a dispensing valve having a first flow path configured to dispense a first fluid and a second flow path configured to dispense a second fluid such that the first fluid and the second fluid mix downstream and form a mixed beverage. A flow control device regulates flow rate of the first fluid through the first flow path, and a shutoff valve selectively closes to stop flow of the first fluid through the first flow path. A sensor is configured to sense the flow rate of the first fluid, and a controller automatically controls the flow control device to adjust the flow rate of the first fluid and thereby obtain a desired fluid ratio of the mixed beverage.Type: GrantFiled: May 1, 2020Date of Patent: July 18, 2023Assignee: Marmon Foodservice Technologies, Inc.Inventors: Brian Mastro, Christopher F. Zemko, Mark Lytell, David K. Njaastad, Craig Pavlich, Steven M. Shei

Patent number: 11454438Abstract: An ice dispensing system is provided. The system includes multiple sidewalls forming an ice bin cavity configured to store ice. The system further includes an auger drive assembly. The auger drive assembly includes a drive assembly that is coupled to one of the multiple sidewalls and has a motor configured to rotate a drive gear. The auger drive assembly further includes an auger assembly positioned within the ice bin cavity. The auger assembly includes a helical auger coupled to an auger gear. The drive gear is configured to mate with the auger gear to drive rotation of the helical auger and cause ice to be dispensed through an ice chute.

Patent number: 11230467Abstract: A detection device for detecting that a source is sold-out for a beverage dispenser, the beverage dispenser dispensing from the source via a valve controlled by a solenoid. A circuit board is configured to be positioned on the valve proximal to the solenoid. A detector is coupled to the circuit board, where the solenoid creates a magnetic field when dispensing from the valve, and where the detector detects the magnetic field created by the solenoid and consequently produces an electrical output. A control system is coupled to the circuit board in communication with the detector. The control system is configured to access threshold data and to compare the electrical output of the detector to the threshold data. The control system indicates that the source is sold-out based upon the comparison of the electrical output to the threshold data.Type: GrantFiled: November 3, 2020Date of Patent: January 25, 2022Assignee: Marmon Foodservice Technologies, Inc.Inventors: Daniel Prochaska, E.
