Abstract
This invention provides a system and a method of economically dispensing hot beverages at precise temperature ranges in a continuous manner suitable for large-scale high-volume usage. An on-demand heater is used to heat water to a preset temperature range. The hot water is circulated to a dispensing head and recirculated back to the heater by a recirculation pump to provide a continuous flow of hot water. A supply of beverage concentrate is flowed into the dispensing head by a peristaltic pump. Upon activation of a button, the hot water is flowed into a nozzle of the dispensing head to create a vortex-like flow. The beverage concentrate is injected into the vortex-like flow and mixed with the hot water to form the hot beverage which is dispensed from the dispensing head.
