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.

A portable warming blender includes a base assembly with a recessed portion; a temperature control system; a detachable agitator rotatably mounted on an axle extending longitudinally into the recessed portion; an electric motor; a rechargeable power system; and a controller. The base assembly includes a housing with a cylindrical sidewall, housing the motor, the power system, and the controller. An inner surface of the recessed portion is threaded. The temperature control system includes a temperature sensor and a heating element. The temperature sensor is mounted adjacent to the axle. The heating element heats the recessed portion. The motor is magnetically coupled with the agitator. The rechargeable power system includes a rechargeable battery and a charging port. The controller selectively transmits power to the temperature control system and the motor from the power system when an operating mode is selected. The blender warms, blends, or both in one device anywhere, anytime.

A fluid mixing system includes a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment; a retainer coupled to the second end of the flexible bag, the retainer having a retention cavity formed thereon that communicates with the compartment of the flexible bag; and an elongated member having a first end rotatably coupled to the first end of the flexible bag and an opposing second end freely disposed within the retention cavity of the retainer so that the second end of the elongated member can rotate within the retention cavity relative to the retainer.

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.

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.
