Devices and methods for beverage brewer regulation

Abstract

An apparatus for controlling pressure in a brewing system during a brew cycle can include a sensor for reading a temperature of a fluid in a heater tank and means, coupled to the sensor, for selectively activating a heater element in the heater tank based at least in part on the temperature reading. The apparatus can also include means, coupled to the sensor, for determining if the temperature of the fluid in the heater tank has reached a desired temperature. The apparatus can also include a pump for displacing the fluid in the heater tank with additional fluid from a reservoir, means for measuring a current drawn by the pump, means for comparing the measured current drawn by the pump to a threshold current, and means for selectively changing a voltage supplied to the pump to displace a desired amount of fluid in the heater tank.
