A vane for an impeller of an agitator includes a socket having a base plane configured to mount the vane to an impeller, and a blade configured to mix a process fluid, the blade having a leading edge, a trailing edge, and a blade tip extending from the leading edge to the trailing edge at an end of the blade facing away from the socket, the blade having a pressure side and a suction side, and the pressure side having a first concave region towards the leading edge, a second concave region toward the trailing edge and a convex region between the first and second concave regions.

A small-scale, batch-wise device to simulate high-shear, short-duration emulsification of fluids from various industrial processes at elevated temperatures and pressures for the purpose of determining the quality and stability of those emulsions under different conditions and with different additives. A threaded, transparent tube capable high temperature and pressure is fitted with a threaded bearing with a shaft sealed gas tight at two points with spring-loaded, internally-facing, open rings. A socket head on the external end of the shaft held on a high-speed motor-drive rotates mixing blades on the internal end of the shaft. Process fluids and additives are added to the tube with a vaporizing liquid. The tube is sealed, heated to the process temperature under pressure, then inverted onto the motor drive, by which the blades are rotated at high-speed for a short duration. The tube is righted and the emulsion observed over time at process temperature under pressure.

A mixer is transportable and storable without using much space. A mixer includes a body including a motor and an output shaft rotatable when driven by the motor, extending downward, and being connectable to a mixer shaft, a handle attachable to the body, and a lock unit located on the body. The lock unit is engageable with the handle at an attachment position of the handle to the body to lock the handle at the attachment position. The lock unit is operable to disengage from the handle to unlock the handle at the attachment position.

A rotary machine for acting on a process fluid includes an impeller, a shaft, a drive, a seal and a flush casing. The impeller acts on the process fluid and is mounted on the shaft. The drive is connected to the shaft and rotates the shaft and the impeller about an axial direction. The seal has a sealing element sealing the shaft during rotation of the shaft. The flush casing receives a flushing fluid for flushing the sealing element, and delimits an annular flush chamber extending about the sealing element. The flush casing includes a bushing surrounding the sealing element and delimits a radial leakage gap arranged between the sealing element and the bushing. The bushing delimits an axial leakage gap between the impeller and the bushing, and the width of the axial leakage gap in the axial direction is adjustable.

This disclosure relates to equipment utilized to manufacture chemical agents, particularly biopharmaceuticals. In some embodiments, reactor systems comprising a mobile carriage assembly; a disposable reaction container removably attached to the carriage assembly; and, a carriage holder into which the mobile carriage assembly may be removably inserted are provided.

An industrial mixing machine is disclosed for mixing material to be mixed in mixing containers that are open on the connection side and differ in at least one feature of their design, wherein one mixing container is attachable in each case to the mixing head of the mixing machine for mixing the material to be mixed contained therein, and wherein at least two mixing tools differing in at least one feature of their design are mountable on a mixing head of the mixing machine. The mixing machine has a detection device which is configured to determine whether the mixing tool currently mounted on the mixing head matches with the mixing container which is to be connected to the mixing head and in which the material to be mixed is located, and a safety device in communication with the detection device, which prevents the mixing tool and the mixing container opening from being brought together when the detection device detects that the mixing tool mounted on the mixing head does not match with the mixing container.

A jar or other storage container with an integrated stirring device, where the contents of the jar or storage container can be stirred and mixed together without having to completely open the jar or storage container. The core components in one embodiment are a top portion that contains external threads, a lid portion which contains internal threads, a spindle with an etched self-reversing screw pattern, a hub, one or more stirring blades, and a nut. The stirring blades have one end attached at a hub that is free to rotate on the spindle, the other end is attached to a nut that can travel up and down the self-reversing screw pattern, and the spindle is fixed to the lid portion. The surface area of the stirring blade(s) can be changed to accommodate different thicknesses and viscosities of different fluids and semi-fluids placed in the storage container.

An electric mixer can include a motor, an interchangeable paddle assembly, and a mounting plate. The mounting plate attaches to the top of a cooking vessel and includes a pair of clamping plates adapted to span a diameter of various size cooking vessels. The motor is attached to the mounting plate and is operably connected to the paddle assembly providing power to rotate the paddle and stir the contents of the cooking vessel.

A rotary machine for mixing, pumping or agitating a fluid includes an impeller for acting on the fluid, a drive unit for rotating the impeller around a rotation axis, a drive shaft connecting the impeller with the drive unit, a mounting flange for fastening the rotary machine to a wall of a vessel, and a support structure for supporting the rotary machine, the support structure comprising at least one leg, each leg extending in a vertical plane from a first end along a longitudinal axis to a second end, each leg including an outer member and an inner member coaxially arranged in the outer member, and the inner member slidingly movable relative to the outer member for adjusting the length of the respective leg. In addition, a method of mounting a rotary machine for mixing, pumping or agitating a fluid to a wall of a vessel is proposed.

Disclosed is a stirring device (D) including a screw shaft (1) driven by a drive unit, the screw shaft (1) being guided with respect to a body by way of a bearing, the stirring device furthermore including a seal (8) rigidly secured to the body and in contact with the ball joint (7) so as to ensure sealing with respect to the fluid to be stirred. The seal (8) is mounted on a seal holder (9), the seal holder (9) including a contact region (10) and being able to take up two positions, a first, operating position in which the seal (8) is in contact with the ball joint (7), and a second, maintenance position in which the contact region (10) is in contact with the ball joint (7).
