A milk powder brewing machine comprising a shell, a mixing bin, a milk powder box, a water storage tank, a constant-temperature bin, a drip tray, a thick-film heater, a spiral cooling pipe and a controller. An air extraction port is provided on the mixing bin, and a moisture-proof assembly is arranged above the air extraction port. The moisture-proof assembly comprises a draught fan and a wind-shield cover. Water outlet of the water storage tank is connected to a cooling pipe, and a spiral pipe is arranged in the cooling pipe. A normal-temperature water outlet is connected with the cooling pipe, which is further connected with the thick-film heater. The thick-film heater is connected with a spiral cooling pipe, which is further connected with the constant-temperature bin through a spiral pipe. The present disclosure is moisture-proof, may be conveniently disassembled, and is capable of improving the cooling effect.

An improved flow rate metering device that provides for the mixing and dispensing of two or more fluids to form final mixture, for example, for automatic washing of cars and trucks. More specifically, the invention is a system that mixes and ejects chemicals, creating a very precise mixture of one or more chemicals with a dilutant, such as water. The device also has the capability of monitoring an entire chemical dilution and release system, comprising multiple chemicals, and using software to document past and current usage rates, along with predicting future usage rates based upon both past usage rates and environmental conditions.

A feed mixer apparatus that includes a mixing chamber for receiving feed, and having a mixing element situated therein for mixing the feed, a transmission having a plurality of gears and connected with a mixing element, a drive system having a plurality of drive system components, including the transmission, a torque sensor interconnected with at least one drive system component, a control unit having a display and a plurality of user inputs, wherein the control unit is in at least indirect communication with the transmission and the torque sensor, and wherein the control unit receives a plurality of outputs from one or more of the transmission and torque sensor, and based at least in part on the plurality of outputs, provides an output command to effectuate a gear change in the transmission.

A portable, self-contained beverage apparatus includes a container assembly having a known storage capacity for storing a consumable liquid, and a dispensing assembly disposed within the container assembly that dispenses variable, non-zero quantities of additives into the consumable liquid. The dispensing assembly includes multiple apertures structured and arranged to retain vessels containing the additives to be dispensed into the consumable liquid. The beverage apparatus also includes a level sensor disposed within the container assembly that determines a consumable liquid level of the consumable liquid stored in the container assembly. In certain embodiments, one or more positive displacement pumping mechanisms are configured to pump additive liquid from additive containers into a beverage chamber.

The present invention relates a grinding liquid mixing and supplying system, comprising: a stock solution barrel, a stock solution circulation tank, a grinding liquid mixing tank, a grinding liquid supplying tank, which are configured with pipelines that interconnects each other; and capacitive liquid level sensors connected in parallel with these tanks. The stock solution circulation tank is provided with a first pipeline, the first pipeline is provided with a first filter and a first pump, and the first pipeline allows the stock solution to flow out from the stock solution circulation tank, to be pressurized by the first pump, to be sent to the first filter, and to flow back, so as to be circulated and filtered. The capacitive liquid level sensor detects a liquid level and monitor whether the liquid is normal in the tanks, so as to maintain and ensure the output quality of the grinding liquid.

Embodiments of the present disclosure involve methods, devices, and systems for hydrating polymers using multiple mixing chambers. Adjacent mixing chambers may be coupled using an under-over baffle, and each mixing chamber may be generally rectangular with rounded corners.
