To simplify the handling of a dispersing device (1) and for the unique identification of dispersing tools (5) that are connectable to a drive unit (3) of the dispersing device (1), it is provided that the dispersing tool (5) has a transponder (10) and the dispersing device has a transmitter-receiver unit (11) for reading out the transponder (10).

This invention belongs to the field of biomass energy utilization at the large scale. A material stirring device for a biomass bin includes a transmission mechanism, a main stirring mechanism, and an auxiliary stirring mechanism. The main stirring mechanism includes a cylinder connected to the transmission mechanism. The outer wall of the cylinder is provided with a hollow stirring rod. The auxiliary stirring mechanism includes a rotating shaft vertically penetrating through the hollow stirring rod. Both ends of the rotating shaft are provided with stirring blades and the rotating shaft is connected to the transmission mechanism. That the stirring device is easily damaged due to too high density of the biomass material is overcome through the automatic conversion adjustment of the main and auxiliary stirring mechanisms. The continuous discharge efficiency of the biomass bin is improved by the organic integration of over and partial stirring.

The present invention relates to a biological material extraction apparatus. According to the present invention, a tube in which a solution for use in extracting a biological material is contained is rotated to directly mix the solution, and cells where stirring is being conducted in each step are sealed to fundamentally block stirring-induced pollution between cells, thereby improving an extraction efficiency.

An implement attachment holder for a hand mixer includes a body defining opposed first and second surfaces and first and second mounting projections coupled with the body and extending away from the first surface of the body at respective first and second locations spaced apart at a first distance along a first direction. The attachment holder further includes a device retention projection extending away from the second surface of the body and partially along the first surface to at least partially overlie the first and second locations from which the first and second mounting projections extend. The device retention projection further defines a plurality of attachment channels extending in a second direction normal to the first direction at spaced-apart locations along the device retention projection.

A method for assembling a mixer-container intended for receiving a biopharmaceutical fluid includes providing a container with a mixing device including at least one shaft having an adjustable length, and at least one first bearing attached to a wall of the container, the shaft extending at least into the inner space from the first bearing; a rigid outer device that compresses the container; and a drive motor located outside the container, the first bearing of the container is placed so as to be spaced apart from the motor, and the length of the shaft is adjusted along the main axis by arranging the shaft opposite the motor to enable the motor to rotate the shaft.

A fluid mixing system includes a support housing having an interior surface bounding a chamber. A flexible bag is disposed within the chamber of the support housing, the flexible bag having an interior surface bounding a compartment. An impeller is disposed within the chamber of the flexible bag. A drive shaft is coupled with the impeller such that rotation of the drive shaft facilitates rotation of the impeller. A drive motor assembly is coupled with the draft shaft and is adapted to rotate the drive shaft. An adjustable arm assembly is coupled with the drive motor assembly and is adapted to move the drive motor assembly which in turn moves the position of the drive shaft and impeller. An electrical controller can control movement of the adjustable arm.
