A system for receiving a single-use vessel containing a mixing device has a support structure adapted to receive the single-use vessel and a drive-unit adapted to power, to control, or to power and control a mixing of contents of the single-use vessel when the single-use vessel is arranged in the support structure. The support structure and the drive-unit are provided as separate components that may be arranged both in an operating position, where the drive-unit is connectable to the mixing device of the single-use bag in the support structure, and in a separated position, where the drive-unit is separated from the support structure. The drive-unit comprises a tag reader that, in the operating position, is arranged to read a vessel tag of the single-use vessel arranged in the support structure.

A mixing device for preparing aligot, including a mixing case containing a chamber that opens at an inlet for conveying material to be mixed, and a mixing member, where the mixing member includes at least one roller that is mounted rotating on a motorised shaft, one or more bearing surfaces of the roller being designed to engage in a crushing manner with the surfaces of the chamber of the case.

A control method and control system for an agitating mechanism are provided. The control method includes receiving a load current detected by a current detecting apparatus when the agitating mechanism is rotating along a specific direction; determining whether the rotation of the agitating mechanism meets a preset trigger condition based on the load current; and controlling the agitating mechanism to rotate in a direction opposite from the specific direction when the trigger condition is met. The present invention can reduce the possibility of the electrical components of the agitating mechanism being burnt out and prolong the lifespan of the agitating mechanism. The present invention can improve agitation results of the agitating mechanism. At low speed, the agitating mechanism can perform the agitation gently without damaging the texture of the solid food. At high speed, the agitating mechanism can more homogeneously and finely agitate the mushy food with enhanced agitating efficiency.

The invention provides a system for the preshearing based control of the flow and deformation behavior, i.e., the setting kinetics, and the time dependent shear viscosity, elasticity of aqueous cementitious suspensions that can be used for bone repair and regeneration. The dynamic cement microstructure is tailored to the demands of the surgical tasks (faster/slower setting) or additive manufacturing tasks (lower/higher viscosity) by application of various preshearing conditions. The relationships between the preshearing and pressurization conditions and the setting kinetics and the time dependent changes in elasticity and viscosity are complex and characterization of viscoelastic properties using advanced rheological characterization techniques including small-amplitude oscillatory and steady torsional rheometry is needed a priori to enable such tailoring. The preshearing system is intended to give control on the injectability and setting time of any calcium phosphate cement formulation to the surgeon during an orthopedic surgery where a batch of bone cement is processed. Other possible utilizations of the system include controlling the setting kinetics, shear viscosity and facilitating the resultant flow stability of cementitious ceramic suspensions processed in direct ink writing assemblies for additive manufacturing of cement constructs, in injection systems for restoration and fracking.
