There is disclosed a computer-controlled dispenser system. The system includes a first set of repositories for fluid components suitable for combination into different mixtures, a second set of repositories for viscous components suitable for combination into different mixtures, and a dispensing nozzle where the fluid and viscous components are dispensed. The system further includes a set of valves and pumps for moving fluid and viscous components to a dispensing nozzle and a scale for measuring an amount of fluid and viscous components dispensed from the dispensing nozzle. The system enables computer control to ensure accurate output of both fluid and viscous components according to the instructions received for their creation.

In accordance with presently disclosed embodiments, systems and methods for efficiently handling dry additives to be mixed with bulk material in a blender are provided. The systems may include a support structure used to direct bulk material from one or more portable containers on the support structure to a first outlet location, and a combined metering/transferring system for directing dry additives from another portable container to a second outlet location. Specifically, the metering/transferring system may output a metered flow of dry additives to the blender mixer to be combined with bulk material that is released from the portable containers. The metering/transferring system may utilize a gravity feed outlet coupled to a metered screw or other conveying device to move the dry additive from the portable container to the second outlet location.

Systems and methods for aeration and mixing processes are disclosed.

A system for agricultural irrigation water oxygenation for enriching soil oxygen level comprises a source of compressed oxygen (and not compressed air) coupled to a water line feeding an irrigation system, such as a drip irrigation system. The coupling system may include a pressure sensor for measuring the pressure in the water line, a solenoid safety valve, a control valve, a flow meter and a controller that controls the flow of oxygen from the source of compressed liquid oxygen to the water line using the components of the coupling system, without using a special cavitation valve and using off-the-shelf components while achieving the same benefits as a system incorporating the special cavitation valve.

A temperature-measuring device including a transmitter and a receiver. The transmitter is configured to measure the temperature of the material being contained in a container being revolved and/or rotated, and is configured to transmit data including a value of the measured temperature. The receiver is configured to receive the transmitted data. The transmitter is disposed in or on an upper lid detachably secured to the container, so that the transmitter can detect an incident light emitted from the material, and the transmitter can be revolved along with the container.

A liquid dispensing pump (10) comprises: a first liquid storage cylinder (11), a second liquid storage cylinder (12), a first plunger (13) movably connected to the first liquid storage cylinder (11), a second plunger (14) movably connected to the second liquid storage cylinder (12), and a drive assembly (15) connected to the first plunger (13) and the second plunger (14). The first liquid storage cylinder (11) is provided with a first liquid entry and exit port (111). The second liquid storage cylinder (12) is provided with a second liquid entry and exit port (121). One end of the first plunger (13) is inserted into an internal cavity of the first liquid storage cylinder (11). One end of the second plunger (14) is inserted into an internal cavity of the second liquid storage cylinder (12). Further provided is a liquid dispensing device (100). The advantageous effect of the invention is: during each linear reciprocating movement cycle of the first plunger (13) and the second plunger (14), the first liquid storage cylinder (11) and the second liquid storage cylinder (12) discharge corresponding ingredients according to a pre-determined mixing ratio, and a mixed solution according to the pre-determined mixing ratio is obtained, thereby achieving precise mixing of different ingredients. In addition, the dispensing pump (10) discharges ingredients at a consistent ratio, thereby achieving uniform mixing without a dedicated mixer.

A polymer dispersion system for use in a hydraulic fracturing operation is disclosed. The system comprises (a) a tank assembly comprising an ingress, an egress, and an interior volume for collecting mother solution; (b) a first transfer pump coupled with the egress of the tank assembly: and (c) a second transfer pump coupled with the egress of the tank assembly. The first transfer pump is configured for coupling to a missile unit and a blender unit downstream thereof, but in fluid communication with only one of such units at any given time when coupled. A method of operating said polymer dispersion system is also disclosed.

The present invention relates to a system for the preparation of a packaged food composition, wherein the system comprises a collecting unit, a weighting unit, a mixing unit, a filling unit, transferring units and a control unit.

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.

A portable preparation assembly to prepare liquid cosmetic/cleanser products in a personalised way has a container which is configured to contain a solvent liquid and includes a base wall, a lateral wall and an upper opening opposite to the base wall; a housing seat configured to house a solid cosmetic/cleanser and arranged at least partially inside the container; and a stirring device which is configured to stir the solvent liquid in the container so as to determine at least partial dissolution of the solid cosmetic/cleanser in the solvent liquid and mix the dissolved solid cosmetic/cleanser with the solvent liquid to obtain the liquid cosmetic/cleanser product.
