A method for mixing a fluid includes: dispensing a first volume of a fluid into a flexible container, the flexible container being at least partially disposed within the chamber of a support housing; repeatedly moving the support housing and the flexible container contained therein so as to mix the first volume of fluid within the flexible container; adding further fluid into the flexible container after moving the support housing to form a second volume of fluid; and manipulating a mixing element within the flexible container so as to mix the second volume of fluid.

A food processing hub (10) comprising an attachment connector (15) for connecting to a food processing attachment (20); wherein the hub (10) is adapted to supply a fluid to the attachment (20) via the attachment connector (15).

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.

An animal trap sensor includes a base having a distal end and a proximal end, a switch having a first metallic element and a second metallic element, and a signal unit, in which, when the first metallic element contacting the second metallic element, thereby forming a closed circuit, such that the signal unit transmits a signal to an off-site receiver. Or, an animal trap sensor includes a first portion and a second portion electrically connected with a signal unit including a power supply, in which, when the first and the second portions are disposed at a first distance between each other, thereby generating an output property, in which, when the first and the second portions are disposed at a second distance between each other, which is different from the first distance, thereby changing the output property and causing the signal unit to transmit a signal to an off-site receiver.

Agitating device (10) for a digester (1) of a biogas plant (100) having a housing (11) and a driving device (12) for rotatably driving the agitator blades (13-15). The driving device (12) comprises a drive shaft (16) and an electric drive motor (20) wherein the drive motor (20) is accommodated sealed in the housing (11). The drive motor (20) comprises an outer, hollow stator (21) and a rotary rotor (22) which is centrally accommodated therein and is configured at least partially hollow. The rotor (22) is rotatably supported at the housing (11) and comprises a coupling device (23) for non-rotatable coupling with the drive shaft (16) to drive the at least one agitator blade (13-15) by means of the drive shaft (16).

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.
