The device includes a vessel to be filled with a mixture of water and a component producing foam, where the vessel comprises a device for blowing air into the mixture to produce foam. It is provided according to the disclosure that the device comprises at least two vessels to be filled with the mixture arranged one above the other in a vertical direction in tiers, where the vessels comprise the device for blowing air into the mixture to produce foam, where the vessels are open towards an outlet region such that the foam produced in the vessels is merged in the outlet region.

Disclosed are various embodiments of a rocker-style treatment tank equipped with instrumentation. In one embodiment, a rocker treatment tank includes a dasher configured to oscillate within treatment liquid in the rocker treatment tank. The dasher includes a dasher shaft, one or more dasher arms coupled to the dasher shaft, and at least one dasher blade coupled to the dasher arm(s). The rocker treatment tank also includes one or more sensors configured to provide data directly or indirectly indicating a torque transmitted to the dasher to effect oscillation.

A method for controlling the saturation level of gas in a liquid discharge includes obtaining temperature and pressure measurements of a solvent in a mixing vessel and obtaining a pressure measurement of a source feedstock in a feedstock tank, correlating the temperature and pressure measurements of the solvent to baseline data to generate a theoretical uptake rate for the source feedstock into the solvent and a theoretical flow rate of the source feedstock into the mixing vessel, and determining a required opening setting for a feedstock valve in the feedstock input line in order to achieve a desired liquid displacement in the mixing vessel. The method includes determining an uptake duration and achieving an uptake displacement equivalent to the reverse of the desired liquid displacement. The method includes generating a valve operating control law for how the feedstock valve should function in a cycle.

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.

The controller that receives at least one sensor signal indicative of a measured profile of a particulate material within a storage tank of an agricultural system. The controller also determines whether a variation between the measured profile and a target profile is greater than a threshold value. The controller outputs a first output signal to a user interface indicative of instructions to inform an operator of a profile variation, outputs a second output signal to an agitator indicative of activation of the agitator, or a combination thereof, in response to determining that the variation between the measured profile and the target profile is greater than the threshold value.

A particulate material sensing and agitation control system of an agricultural system having a drive system configured to operate an agitating system, and a controller having a memory and a processor. The controller is configured to receive at least one sensor signal indicative of a profile of a particulate material within the agricultural system, and output a control signal to instruct the drive system to operate the agitating system in a selected operating mode of a plurality of operating modes based on the profile of the particulate material. The agitating system is configured to interact with the particulate material in each operating mode of the plurality of operating modes, and the plurality of operating modes includes an agitation mode and a leveling mode.

A particulate material agitation and leveling control system includes a controller having a memory and a processor. The processor is configured to receive a sensor signal indicative of a measured load on a drive system coupled to an agitation and leveling system, select an operating mode of the agitation and leveling system from an agitation mode and a leveling mode based on the measured load, and instruct the drive system to operate the agitation and leveling system based on the operating mode.

An agitation control system of an agricultural system. The agitation control system includes an agitator that induces movement of particulate material through the agricultural system. An agitator motor couples to the agricultural system to move the agitator. A first motor couples to the agitation control system. The first motor includes a first sensor that detects a first temperature of the first motor and emits a first signal indicative of the first temperature. A controller couples to the agitator motor and to the first motor. The controller receives the first signal indicative of the first temperature from the first sensor and determines an ambient temperature from the first temperature. The controller controls the agitator motor in response to the ambient temperature.

A method of manufacturing a coffee grounds powder includes: an inputting process in which coffee grounds are input into a mixing portion of a caffeine reduction apparatus; a water inputting process in which an inlet and outlet pipe is opened and water is filled inside the main housing such that the coffee grounds input into the mixing portion are submerged; an ultraviolet ray emitting process in which ultraviolet rays are emitted to the water and an inside of the mixing portion; an elution water discharging process in which an elution water in which caffeine is decomposed is discharged to an outside from the main housing; a drying process in which the coffee grounds that remain in the mixing portion are dried by rotating the mixing portion; and a mixing process in which the coffee grounds in which drying is finished are mixed with a viscous additive.
