Embodiments described herein relate to systems and methods of extracting liquid from empty barrels. In one aspect, a method includes heating a barrel with less than about 10 ml of free liquid disposed therein to expand pores in the barrel. The method further includes applying, after the heating, a negative pressure to an interior of a vessel in which the barrel is disposed, such that an amount of liquid is extracted from the barrel. The method includes collecting, after the applying, the amount of liquid within a collection container. In some embodiments, collecting the amount of liquid includes pumping the liquid through a tube that is disposed between an outer surface of the barrel and the collection container. In some embodiments, heating the barrel is via a heated blanket wrapped around the barrel. In some embodiments, heating the barrel is via placing the barrel in an oven.

A vehicle fluid exchange machine is disclosed that allows the technician to control the flow into the vehicle or stand-alone cooling or hydraulic system either manually or automatically based on a safe working pressure for the vehicle. If the vehicle's cooling system can handle a higher pressure for example, the technician may adjust the machine's flow to a flow rate consistent with the higher pressure rating while monitoring the pressure across the system. The default setting for the air injection process is automatic, but can also be switched to manual by the technician.

A stirrer includes a stirring shaft; a plurality of mixing wings extending from the lower end of the stirring shaft and spaced from each other around the stirring shaft; and a conical hub connecting the lower ends of the mixing wings.

A system is provided using targeted narrowband radiation emitting devices or arrays of devices that offers a solution to the difficulties surrounding heated product dispensing. Rather than maintaining an entire reservoir of product at a raised temperature, much smaller volumes (single portions or small multiples thereof) can be held ready and at temperature to be dispensed without wasting additional energy on keeping a large volume of product warm. This is achieved by leveraging the unique, targeted nature of these devices to quickly and accurately heat a small amount of product separated out from the main reservoir and held ready for dispensing.

An automated consumable dispenser with a precision method for delivering consumable ingredients in specific proportions to a container up to a specified volume. This method involves the use of a system of sensors and a micro-microprocessor, which detects, digitizes and develops a three dimensional rendering of the container, calculates the container volume and dispenses specific amounts of consumable ingredients. A user is able to pick the level in the vessel to which the consumable ingredients should be dispensed and displays the selected desired level. The embodiments described include an automated dispenser capable of dispensing beverages and food items, either separately or together.

The refillable drinking container for use with a water-dispensing system. The refillable drinking container for use with a water-dispensing system stores a fluid that is consumed as a beverage. The refillable drinking container for use with a water-dispensing system measures the stored fluid. The refillable drinking container for use with a water-dispensing system refills the fluid when the volume of the stored fluid falls below a previously determined level. The refillable drinking container for use with a water-dispensing system heats the stored fluid at a previously determined temperature.

A multiple-piece vacuum-insulated heating tank for use in a water dispenser includes a threaded cover, a thermal insulation cover, and a heating tank body. The threaded cover is mounted on an upper opening of the heating tank body and includes a plastic cover and a protective cover mounted on and around the plastic cover. The thermal insulation cover is fitted in the upper opening and includes an upper cover and a lower cover. The lower cover is cup-shaped; is mounted with a heating tube, a water inlet pipe, a water outlet pipe, a thermowell, a temperature-sensing heat pipe, a heat collector block, and two snap-action thermostats at the bottom side; and has a sidewall formed with a step adjacent to the bottom side. The heating tank not only has a multiple-piece structure that facilitates mass production and maintenance, but also dispenses with electronic temperature control as is conventionally required.

A water purifier includes a hot water tank for receiving and heating received water by induction heating, a water outlet portion that is at least partially exposed to an outside of the water purifier for discharging hot water, a hot water line that is connected to the water outlet portion to communicate the hot water from the hot water tank to the water outlet portion, a hot water outlet valve that is located at the hot water line and that opens or closes the hot water line based on a control command, a connector that includes a hot water inlet connected to a water outlet pipe of the hot water tank and a hot water outlet connected to the hot water line, and a temperature sensor that is connected to the connector and that is configured to measure a temperature of the hot water that passes through the connector.

A control device, for a water purifier, that dispenses hot water and that includes: an input unit that is configured to receive a command signal; and a controller that is configured to control the water purifier based on the command signal, wherein the controller is configured to: control power output of a heating unit that is configured to heat water stored in a hot water tank of the water purifier, and based on the power output of the heating unit, control temperature of hot water dispensed by the water purifier is disclosed.

A beverage dispense system for a countertop having a water inlet including a solenoid valve and a beverage concentrate inlet to which a bag-in-box containing a supply of liquid coffee concentrate is attached. A beverage dispense font is mounted on the countertop. A water conduit connects the water inlet with the dispense font. A separate liquid beverage concentrate conduit connects the beverage concentrate inlet with the beverage dispense font. An electric syrup pump pumps liquid coffee concentrate from the bag-in-box to the end of the dispense font. A control unit controls the separate delivery of water from the mains water inlet and/or liquid coffee concentrate to the end of the beverage dispense font. Where water and liquid coffee concentrate are delivered, they will mix in the beverage receptacle.
