Patent number: 5953981Abstract: A twin brewer system (30) with a pair of brewers (30A, 30B) each with a controller (158) for controlling the application of electrical power to a hot water heater, disables the application of electrical power to the heater (154) of one brewer (30A, 30B) in response to actuation of a start brew switch of the one brewer (30A, 30B) while electrical power is being applied to the heater (154) of the other brewer (30A, 30B). The controllers also respond to a hot water quantity sensor (164, 168) and a responsive delay circuit for disabling dispensing of hot water in response to actuation of the brew start switch (50) until a sufficient quantity of hot water is in a hot water dispenser tank (152) needed for the brew cycle. Indication lamps indicate when the brew cycle is being delayed and when brewing is not being performed. Actuation of a single emergency stop switch (138) stops hot water dispensing of both brewers (30A, 30B).Type: GrantFiled: September 18, 1997Date of Patent: September 21, 1999Assignee: Food Equipment Technologies Company, IncInventor: Zbigniew G.
