A method for processing a fluid includes removably securing a retention member to a vessel that bounds a chamber; inserting a collapsible bag within the chamber of the vessel; securing the bag to the retention member so that the bag is supported within the chamber of the vessel; and dispensing a fluid into a compartment of the collapsible bag supported within the chamber of the vessel. The fluid can be mixed within bag while the bag is disposed within the vessel.

A transmission mechanism suitable for a double-rotating paint mixing machine, comprising a rotating spindle installed on a rack, a pressing spindle installed in the rotating spindle, a guide rail frame fixed at a front end of the rotating spindle, an upper supporting arm and a lower supporting arm, and an upper pressing disc and a lower pressing disc, which are installed on the upper supporting arm and the lower supporting arm and are capable of rotating, wherein the rotating spindle can drive the entire guide rail frame to rotate along the axis of the rotating spindle, meanwhile the upper pressing disc can be driven by a transmission system to rotate around its own axis at the same time, wherein the rotating spindle is engaged with and disengaged from the driving wheel through a driving disc locking device.

A fluid mixing system includes a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment. A first rotational assembly includes a first casing mounted to the first end of the flexible bag and a first hub rotatably mounted to the first casing. A second rotational assembly includes a second casing mounted to the second end of the flexible bag and a second hub rotatably mounted to the second casing. An elongated member has a first end coupled with the first hub and an opposing second end coupled with the second hub, the connector being flexible and having a uniform flexibility along its entire length. A first impeller is mounted to the connector.

A bioreactor system and packaging is provided. The bioreactor system includes a vessel for housing biomaterials for processing and a support structure. The vessel includes a flexible material defining a chamber and a mixing system positioned within the chamber. The mixing system includes an agitator for imparting motion and mixing to the contents of the vessel and includes a base affixed to the flexible material at a base section of the chamber, a shaft moveably mounted in the base and extending from the base into the chamber and at least one mixing element mounted to the shaft, the shaft configured to be driven by a motor magnetically coupled to the shaft and external to the lower portion of the chamber. The support structure is connected to the mixing system such that the shaft is moveable therein and configured to cooperate with an external structure to provide support for the shaft.

An efficient automatic liquid-liquid extracting machine includes a body. At least one set of stirring extractor is arranged on the body, the stirring extractor includes a cylindrical separating funnel and a stirring motor that are fixed on the body, a bottom funnel opening of the cylindrical separating funnel is connected to a three-way liquid separating device, the stirring motor is arranged opposite to the opening of the cylindrical separating funnel, a motor shaft of the stirring motor is connected to a stirring device, and a stirring end of the stirring device penetrates into the cylindrical separating funnel. Since multiple mechanical stirring devices are used in the analysis of semi-volatile organics, the extraction process for multiple samples can be performed synchronously at the same time, and the solvent and the solute are brought into full contact due to the rotary mechanical stirring up and down.

A universal wall and bridge mounted aeration apparatus has a track extending between two distinct elevations that is coupled to a wall and bridge mount. An aeration unit is pivotally coupled to the track and has an aerator adapted to operatively at least partially submerge within and aerate a liquid. A selective mover or drive is adapted to operatively move the aeration unit along the track and thereby vary an elevation of the aeration unit. The universal wall and bridge mount supports the track and aeration unit. The universal wall and bridge mount has a first configuration for mounting to a structure such as a stationary bridge, and a second configuration for mounting to a wall. The universal wall and bridge mounted aeration apparatus may be adjusted to position the propeller after installation under the surface of the liquid through three axes of motion freedom.

A heating and stirring device is described herein that comprises a base configured to removably attach to one of a beverage container and a beverage container lid, the base containing a power supply, a controller, and a motor, and an agitator having a body and a length with a first end portion configured to be supported by the base, and a second end portion, wherein the first terminal end is configured to be outside of the beverage container and the second end portion is configured to be inside of the beverage container. Corresponding systems and methods also are disclosed.

Apparatus that mixes non-homogenous fluid. A threaded shaft within a housing circulates fluid within a container to effect mixing. In one embodiment, when placed in a container of fluid, the housing the fluid is recirculated through opposing ends of the housing. In an embodiment of a related method for mixing, a pump housing containing a screw journaled for rotation receives fluid within a container and conveys the fluid therethrough to circulate a fluid portion in the container along an exterior surface of the housing for mixing with another fluid portion to improve fluid homogeneity. After mixing, the portion of the fluid which first circulates through the housing may recirculate through the housing with said another portion of the fluid. The fluid may be continuously mixed and recirculated through the housing.

An agitating system of an agricultural system includes a brace configured to couple to a sub-hopper of the agricultural system and a support configured to engage the brace and to support a shaft within the sub-hopper. The support includes a support piece having a first portion configured to receive the shaft and the brace has a recess configured to receive the first portion of the support piece while the support is in an installed configuration.
