A method and a device used to store a product inside a receptacle. The product includes a first liquid component and at least a second component. Inside the receptacle, the product is circulated by a conveying apparatus which is positioned in the region of a tubular guide element arranged inside a receptacle. At least one component of the product fed to the receptacle flows first into an internal space of the guide element.

A stirring device, in particular reactor stirring device, has at least one holder which is configured for holding at least one brittle unit within a container relative to at least one container wall of the container, and which has at least one holding unit for this purpose. At least one holding position of the holder relative to the container wall can be adapted by means of the holding unit.

A flocculation and sedimentation apparatus has: sedimentation tank that causes flocs in raw water to be sedimented and separated; sludge concentration tank that is surrounded by sedimentation tank and that collects and concentrates the flocs; and raw water supply mechanism having center line that passes through sludge concentration tank, wherein raw water supply mechanism rotates about center line and supplies the raw water to sedimentation tank. Raw water supply mechanism includes: raw water introducing portion that is located on center line and to which the raw water is introduced, raw water supply port that is open at a lower portion of an inner space of sedimentation tank and that supplies the raw water to sedimentation tank, and pipe portion that communicates both with raw water introducing portion and with raw water supply port and that extends above sludge concentration tank in a direction away from center line.

A stirring device, in particular reactor stirring device, has at least one holder which is configured for holding at least one brittle unit within a container relative to at least one container wall of the container, and which has at least one holding unit for this purpose.

At least one holding position of the holder relative to the container wall can be adapted by means of the holding unit.

A device for treating wastewater liquids, the device comprising a housing (4) incorporating a membrane supported biofilm reactor (MSBR) (2) of the type comprising a lumen containing a gas phase, a liquid phase, and a gas permeable membrane (20) providing an interface between the gas and liquid phases; and a means (6) for mixing the wastewater liquids in the device, wherein the means (6) for mixing the wastewater liquids is configured to create a mixing intensity sufficient to ensure that there is contact between the membrane (20) and the wastewater liquid to be treated.

An apparatus for producing protein breakdown on meat material is disclosed. The apparatus comprises at least one tool configured for producing protein breakdown on meat material. The tool forms a mixing chamber for meat material. The mixing chamber has opposite chamber walls rotatable relative to each other for controlling forces exerted on meat material therebetween. A method for producing protein breakdown on meat material and a meat production plant including at least one apparatus are further disclosed.

An agitator device, in particular a draft tube agitator device, with at least one stirring unit, which is rotatable around a rotary axis, which is configured for conveying a fluid in an axial conveying direction and which includes at least one rotor blade element, the projection of said rotor blade element onto a plane that is perpendicular to the rotary axis having an at least substantially circular-arc-shaped outer contour,

the rotor blade element comprises at least one first region, which is situated in a blade plane and is at least substantially planar, and includes a second region, which is curved out of the blade plane.

A decanting vessel has an internal pump for recirculating a beverage such as wine and aerating it within the decanter.

An apparatus for treating water in a reservoir includes a funnel. A support assembly supports the funnel in a lengthwise upright orientation when the funnel is submerged. A water moving arrangement is arranged to move water through the funnel in a direction from an inlet at an upper end of the funnel towards an outlet at lower end of the funnel.

A powdery-material feeding device is configured to feed a powdery material to a compression-molding machine configured to obtain a molded product by filling a die bore with the powdery material and to compress the powdery material with punches. The powdery-material feeding device includes a detector configured to detect a biologically-originated foreign matter mixedly contained in the powdery material to be fed to the compression-molding machine, and a controller configured to control to remove the powdery material mixedly containing the biologically-originated foreign matter detected by the detector to avoid feeding of the powdery material mixedly containing the biologically-originated foreign matter to the compression-molding machine, or to control to stop the feeding of the powdery material to the compression-molding machine.
