In some embodiments, apparatuses and methods are provided herein useful to utilizing a sonication probe. In some embodiments, there is provided a system for utilizing a sonication probe to cook rice including a housing; a pH sensor; a temperature sensor; a viscosity sensor; an ultrasonic generator; a memory; and a control circuit configured to: receive a desired shelf life value of one or more shelf life values; obtain a first predetermined combination of a plurality of different predetermined combinations corresponding to the desired shelf life value; control an operation of the ultrasonic generator; determine the pH value, the temperature value, and the viscosity value; determine whether each of the pH value, the temperature value, and the viscosity value are respectively within a corresponding threshold; and in response, cause the ultrasonic generator to stop emitting one or more sound waves to substantially halt breakdown of amylose of the rice.

A liquid heating appliance for making a beverage, the liquid heating appliance comprising: a plurality of heating components for heating a liquid, where at least a first of the plurality of heating components is powered using mains power, a power management system, wherein the power management system comprises: a controller, and an energy storage device, wherein the controller is arranged to control an amount of the mains power applied to the first of the plurality of heating components, and further arranged to control an amount of stored power from the energy storage device to be applied to at least a second of the plurality of heating components.

An electric dispensing kettle system with a dispensing kettle seats on to and docks to a control station. The dispensing kettle includes a weighted handle for controlled or balanced pouring. The control station provides controlled power to a heating element within the dispensing kettle with the dispensing kettle seated on to docked to the control station. The control sation includes a PID controller or control loop feedback circuit that continuously modulates power to the heating element based on actual temperature reading received from a thermocouple structure. The control station also includes an electronic dispaly that simultaneously displays an actual temperature of the steeping liquid and the target temperature of the steeping liquid within the dispensing kettle.

A hot water dispenser and a method for determining a boiling point of water in the same. The hot water dispenser contains a reservoir, a heating element, and a sensor. The method includes heating water in the reservoir with a first power value of the heating element during a first period of time until a value indicative of a threshold temperature of water is determined; upon reaching the threshold temperature, heating the reservoir water with a second power value of the heating element, which is lower than the first power value, during a second period of time until a water-temperature-rise-per-time value is lower than a first predetermined value; subsequently, increasing the power value of the heating element to a third power value during a third period of time; determining the boiling-point temperature of water by determining the highest temperature of water between the first and third periods of time.
