Digester (1) having an agitating device (10) and an agitating device (10) and a method for manufacturing an agitating device (10), the agitating device (10) comprising multiple agitator blades (21-29) which agitator blades (11-13) comprise a plurality of blade sections (21-29) angled relative to one another. The blade sections (21-29) of the agitator blade (11-13) are angled relative to one another such that the agitator blade gradient (11-13) decreases with the distance (30) from a central rotational axis (19) increasing to configure the agitator blade in a flow-optimized three-dimensional shape.

Provided herein are containerized liquid formulations comprising a plurality of agrochemicals. The formulations comprise a plurality of parallel liquid layers, wherein each layer is disposed within the container such that it is in contact with at least one adjacent layer at an interface. Also provided are methods of preparing, storing, shipping, and using the containerized liquid formulations.

A mixing system for mixing a liquid includes a first impeller segment having a first mount and a first mixing blade secured to the first mount and a second impeller segment having a second mount and a first mixing blade secured to the second mount, the second impeller segment being separate and discrete from the first impeller segment. One or more drive members are secured to the first impeller segment and the second impeller segment for concurrently rotating the first impeller segment and the second impeller segment about a rotational axis. The first impeller segment and the second impeller segment are secured to the one or more drive members so that a plane extending normal to the axis of rotation intersects with the first mixing blade of the first impeller segment and the first mixing blade of the second impeller segment.

An agitator for being disposed in a container and rotated to agitate fluid in the container includes a shaft and an impeller attached thereto. The shaft, being supported relative to the container, provides an input for attachment of a rotation mechanism for causing rotation of the impeller and shaft. The impeller includes an impeller body defined by a hub portion for receiving and being mounted to the shaft, and a plurality of blades extending radially outwardly from a longitudinal axis of the hub portion. The impeller body is a single piece of unitary construction, such as where the plurality of blades are formed in a manner that the blades are integral with the hub portion at the formation of the blades.

Disclosed is a rotating propeller (1), comprising a rotating shaft (2), a hub (3), and a plurality of blades (4). The rotating shaft (2) is connected to the hub (3). The plurality of the blades (4) are circumferentially and uniformly arranged by taking the axis line (201) of the rotating shaft (2) as a center. All of the blades (4) are rotatably connected to the hub (3) and can rotate along axes of rotary shafts (401) corresponding to the blades (4). All of the axes of the rotary shafts (401) do not pass through the axis line (201) of the rotating shaft (2).

In one embodiment, a method, comprising influencing fluid flow from a tank to one or more nozzles via a filtering apparatus; and diverting a portion of the fluid flow through plural filters of a different mesh size back to an agitating mechanism through a lower portion of the tank.

Disclosed is a container for transporting a biopharmaceutical fluid, the container including a leak-tight wall having an outer portion and an inner portion, the outer portion and the inner portion delimiting between them an intermediate space that may be inflated under pressure with an inflation gas, the container being adapted to be alternately in: a non-inflated state in which the container is empty of pressurized inflation gas; an inflated state in which the wall of the container is inflated and delimits an internal cavity adapted to contain the biopharmaceutical fluid. The wall includes a peripheral lateral wall around the internal cavity, the peripheral lateral wall being completely rigid or semi-rigid when the container is in the inflated state so as to ensure a protection of the biopharmaceutical fluid.

A liquid mixing system includes a support housing at least partially bounding a compartment. A mount is secured to the support housing. A drive motor assembly is configured to engage a drive shaft for moving the drive shaft within the compartment of the support housing. A four bar linkage system extends between the mount and the drive motor assembly, the four bar linkage system being movable between a first position wherein the drive motor assembly is disposed at a first elevation and a second position wherein the drive motor assembly is disposed at a second elevation that is different from the first elevation.

A chemical mixer tool for use in a storage drum is described. The chemical mixer tool typically comprises a mixer housing assembly in which one end of a mixer shaft is secured, the distal end of the mixer shaft having at least one collapsible impeller assembly removably attached thereon. The chemical mixer tool is configured to be removably secured to the top portion of the storage drum, with the distal end of the mixing shaft extending into the interior of the storage drum.
