A device for slurrying a suspension and a method for operating such a device are disclosed. In an embodiment a device includes a mixing container with an inlet opening configured to introduce the suspension into the mixing container a distributor element having a collecting container and an outlet arm fastened to the collecting container and a shaft with a longitudinal axis, wherein the shaft and the distributor element are arranged inside the mixing container, wherein the distributor element is mounted so as to be freely rotatable around the shaft, wherein the collecting container comprises a collecting opening configured to pass the suspension from the inlet opening into the distributor element, wherein the outlet arm comprises an outflow opening configured to let the suspension leave the distributor element, and wherein the outlet arm is designed such that the suspension is able to flow out of the distributor element starting from the collecting container via the outlet arm and the outflow opening, a flow of the suspension causing a torque on the distributor element so that the torque supports a rotation around the shaft.

The present invention provides a gas-containing base material that can contain and retain a functional gas with a high concentration and a method of producing the same. A method of producing a gas-containing base material including a functional-gas-containing composition includes the following processes.

Process (1):

In this process, a functional gas is supplied to a raw material composition having a gelation temperature in a range of 0.5 C. or higher and 65 C. or lower at which a liquid form is able to be changed to a solid form by cooling while the temperature is maintained at a degree at which the raw material composition is in a liquid form, and the amount of the functional gas which exceeds a saturated solubility when the raw material composition is in a liquid form is uniformly dispersed as fine bubbles

Process (2):

In this process, the liquid raw material composition in which fine bubbles of the obtained functional gas are dispersed is transferred into a filling container and the filling container is filled and sealed.

Process (3):

In this process, the liquid raw material composition in which the obtained fine functional gas bubbles in the sealed filling container are dispersed is cooled at a temperature equal to or lower than the gelation temperature of the raw material composition and solidified.

A mixing unit for mixing a flow of liquid product is provided. The mixing unit comprises a stator forming a hollow sleeve, and a rotor having a circular displacement plate with two opposite sides, wherein at least one side has at least two chambers formed by a plurality of vanes extending in a direction being parallel with a longitudinal axis of the stator, wherein the rotor is arranged within the stator for rotating liquid product arranged in said chambers relative the stator. The displacement plate is tilted relative a longitudinal axis of the stator such that said at least two chambers have different volumes, and a side wall of the stator has at least one exit area comprising at least one through hole for allowing liquid product to exit the stator.

A device and a method for dispersing at least one substance in a fluid is disclosed. The device includes a process housing with a rotor, a fluid supply, a feed line for the at least one substance to be dispersed having at least one outlet opening, as well as a product outlet. The rotor brings about an axial delivery of a supplied fluid at least in some sections. Furthermore, the rotor brings about a radial delivery of the supplied fluid at least in some sections.

The present invention provides subsurface irrigation systems and air injection mechanism and microbubble generating mechanism. The systems of the present invention are operable to provide an evenly distributed air microbubbles in a stream of fluid (e.g., subsurface irrigation water) to evenly provide gas therein (e.g., oxygen for plants receiving the irrigation water along an entire length of an irrigation line). The microbubble generating mechanism may use pressure generated from flow of fluid to cavitate the fluid and thereby distribute gas microbubbles in the fluid. In irrigation examples, the resulting air infused water delivers an effective amount of oxygen to the roots of the irrigation crops.
