Forces and loads on the impeller are directly supported by the motor and measured by the multi-axis load cell. In some embodiments, a programmable controller generates control signals that control the motor's speed (RPM), torque and direction of rotation, and receives feedback signals for adjusting the motor's speed and/or torque and/or direction of rotation.

The present set of embodiments relate to a bioproduction system, method, and apparatus for creating a scalable bioreactor system. Specifically, the present set of embodiments enable the determination of bioreaction performance characteristics of a commercial scale by matching operational parameters between a small test scale bioreaction to that of a commercial scale bioreaction. The system and methods do not rely on simply making bioreactor apparatuses across scales the same dimensionally which would not account for differences in fluid dynamic properties between very small to very large volumes, but requires tuning of a variety of systems (mixing assembly, sparger system, and headspace airflow system) in conjunction with one another to achieve predictive outcomes.

The invention relates to a method for monitoring and controlling the operation of a liquid flow generator (1) configured for operation in a tank (18) housing in a liquid comprising solid matter. The flow generator (1) comprises a propeller (3) and a main body (7) having a drive unit (4), wherein a control unit (4) is operatively connected to the flow generator (1) in order to monitor and control the operation of the flow generator (1), the method comprises the steps of: a) driving the propeller (3) in a normal direction of rotation, wherein the liquid flow is directed from an upstream side of the propeller (3) towards a downstream side of the propeller (3), wherein the main body (7) is located at the upstream side of the propeller (3), b) performing a cleaning sequence in response to a main body cleaning signal, wherein the cleaning sequence comprises the steps of: i) stopping the propeller (3) from rotating in the normal direction of rotation, ii) driving the propeller (3) in a reverse direction of rotation, wherein the liquid flow is directed from the downstream side of the propeller (3) towards the upstream side of the propeller (3) and along the main body (7) in order to remove any solid matter accumulated on the main body (7), and iii) stopping the propeller (3) from rotating in the reverse direction of rotation, c) resume driving of the propeller (3) in the normal direction of rotation.

A meshing-type rubber internal mixer and a working method thereof are provided. The meshing rubber internal mixer includes a frame mechanism, a mixing mechanism, and an unloading mechanism. The mixing mechanism is on the upper side of the unloading mechanism. The mixing mechanism and the unloading mechanism are in the frame mechanism. An internal mixing chamber is of a closed structure through first automatic telescopic plates and second automatic telescopic plates. The gap between a first meshing-type rotor and a second meshing-type rotor is small, a material is compressed to enter the space between the first meshing-type rotor and the second meshing-type rotor to be extruded with an internal mixing chamber wall. The material is flaky in the internal mixing chamber, so that the material produces great strain deformation, thereby achieving excellent dispersing and mixing effects.
