One variation of a mixing system includes: a container configured to store consumable beverages; a lid; and a mixer. The lid is configured to transiently couple to the container and includes: a housing; a mixer receptacle; a set of user controls arranged on an outer face of the lid; a set of electronics arranged within the housing and including a motor, a controller configured to actuate the motor responsive to selection of the set of user controls, and a power supply configured to supply power to the motor and the controller; and a set of supports arranged between the motor and walls of the housing and configured to absorb energy output by the motor. The mixer includes: a connector section configured to engage the mixer receptacle to couple the mixer to the motor; and a mixing section configured to mix ingredients in the container responsive to actuation of the motor.

Provided herein are gas mixing systems, comprising a gas inlet for receiving two or more gases and a mixing chamber with a static mixer for mixing the gases. Preferred mixing chambers further comprise a reduced pressure compartment downstream of the static mixer that is in fluid communication with the gas inlet. A gas outlet is in fluid communication with the mixing chamber, and one or more sensors are coupled to the reduced pressure compartment and are configured to continuously sense various parameters such as barometric pressure and the percentage of oxygen in the gas mixture moving through the mixing device. Most typically, the readings of the sensor are pre-compensated for temperature, pressure, and humidity. Also provided herein are methods for using the same.

An algae cultivation system may include: a plurality of panels within a cultivation container, positioned along a first axis perpendicular to the gravitational force, wherein a cultivation volume is created between each pair of panels, and wherein the cultivation volumes are fluidly coupled so as to allow horizontal flow therebetween along the first axis; at least one first sparger, to distribute a first fluid into the container at a first operating flow rate; at least one second sparger, to distribute a second fluid into the container at a second operating flow rate; and at least one controller, to control the first operating flow rate and the second operating flow rate. The first operating flow rate may be adapted to allow turbulent mixing the algae in the cultivation container, and the second operating flow rate may be adapted to allow assimilation of materials in a liquid in the cultivation container.

An exemplary process air recirculation system, and an electric heater mixing apparatus is disclosed herein. Exemplary process air recirculation systems comprise the electric heating mixing apparatus. An exemplary electric heating mixing apparatus comprises: walls defining a first chamber having a first upstream opening and a first downstream opening, and a second chamber having a first upstream opening and a first downstream opening, wherein the second chamber is adjacently disposed to the first chamber, a first inlet damper disposed at the first upstream opening, a second inlet damper disposed at the second upstream opening, and a resistance-type electric air heater disposed in the first chamber.

Metastable state spore incubation mixing systems are described. An example system includes a spores container to store spores, a nutrient container to store nutrients, a water supply line, a syringe tank, a syringe pump, an adjustable valve, a heater, and a controller. In a drawing phase of the system, a controller can cause the syringe pump and the adjustable valve to draw into the syringe tank a volume of spores, nutrients, and water to form a mixture. The controller causes the heater to heat the mixture for a period of time. In a dispensing phase of the system, the controller can cause the syringe pump to expel the mixture through the adjustable valve and into a water distribution system. The controller can direct the system through a number of other phases of operation.

A tumbler crystallizer for crystallizing pelleted, tacky, polymeric materials includes a housing for rotatably supporting a removable paneled drum on rollers. The removable panels may be made of a transparent, heat-insulating material. The drum receives a flow of hot pellets through an inlet chute, and a tumbling action of the drum and internal agitators keeps the pellets in motion relative to each other to prevent agglomeration until they reach a desired level of crystallinity and are no longer tacky. Baffle plates are provided at intervals along the length of the drum to slow the flow of pellets therethrough to increase residence time. Damper plates are provided near the exit end of the drum to aid in building a bed of pellets within the drum, and also to control residence time of the pellets within the drum.

An exhaust aftertreatment system for an internal combustion engine includes an outer casing defining an exhaust flow path for exhaust gases from the internal combustion engine, a selective catalytic reduction unit provided in the exhaust flow path for reducing nitrogen oxides, a urea dosing device for adding urea to the exhaust flow upstream of the selective catalytic reduction unit, and a rotatable mixer device for mixing the urea with exhaust gases upstream of the selective catalytic reduction unit. The exhaust aftertreatment system further comprises an air inlet valve provided upstream of the mixer device for introducing air into the exhaust flow path, and an electric motor arranged for rotating the mixer device to create a suction of air into the exhaust flow path via the air inlet valve.

A sensor system, particularly for monitoring the mixing of at least two fluids and a method for monitoring the mixture of at least two liquids. The present invention provides a sensor system for fluids, comprising at least two level sensor which are arranged vertically one upon the other on and connected to an electronic circuit board, four electrodes of four conductivity sensors which are arranged horizontally next to each other at the bottom of and connected to the electronic circuit board; and a temperature sensor which is connected to the electronic circuit board; a connector for connecting the electronic circuit board to a controller; wherein the electronic circuit board is embedded in a hot melt compound which is surrounded by an injection molded housing.

A caffeine reduction apparatus includes: a main housing provided with an inlet and outlet pipe; a mixing portion including an accommodating portion through which coffee grounds are input inside the accommodating portion, and a blade configured to be rotated inside the accommodating portion such that the coffee grounds are mixed; a driving portion configured to rotate the blade; and an ultraviolet ray emitting portion positioned at an upper portion of the main housing and mounted at an inner side surface of a door that seals an inner portion of the mixing portion, the ultraviolet ray emitting portion being configured to emit ultraviolet rays toward the mixing portion.
