Some embodiments of the disclosure provide systems and methods for a bearingless hydraulic rotary stirring water distributor. According to an embodiment, the bearingless hydraulic rotary stirring water distributor includes a rotary inlet pipe, stirring pipes, water distribution pipes, a ball head shaft, a fixed inlet pipe, a bowl seat, a first seal ring, and a second seal ring. The stirring water distributor is vertically mounted, the fixed inlet pipe is vertically arranged and inserted into the rotary inlet pipe, the fixed inlet pipe and the rotary inlet pipe are mechanically sealed through the seal rings therebetween, the rotary inlet pipe is a vertically mounted pipe, and the rotary inlet pipe is vertically mounted in a semispherical groove of the bowl seat through the ball head shaft mounted at one end of the rotary inlet pipe.

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 blending system is shown and described herein. The blending system may include a base including a motor, a blade base assembly selectively and operably engaged with the base, where the motor drives a blade assembly of the blade base, and a blending container engageable with the blade base. The blade base may be configured to prevent driving of the blade assembly when the blending container is not engaged with the blade base assembly. The blade base may be engaged with the blending container and the blade assembly may mechanically engage with the motor.

A microwavable container for use in a microwave oven that includes provisions to stir or mix food during microwave cooking. This mixing action is achieved by utilizing the motor of the microwave oven. Such mixing provides more even heating of food, and reduces the need to stop the microwave oven to manually stir food.

The sealing performance of a stirring device and the abrasion resistance of a seal are improved. A stirring device includes a stirring tank that defines a stirring chamber; a plurality of stirring blades that are disposed in the stirring chamber; a shear blade drive shaft that extends from a lower side of the stirring tank to the stirring chamber and rotationally drives at least one shear blade among the plurality of stirring blades; and a fixed ring and a rotating ring that is disposed radially outside the shear blade drive shaft and seals between the stirring tank and the shear blade drive shaft. A sealing surface of the mechanical seal structure is formed at the same height as or above a lowermost portion of the stirring chamber.

A fluid mixing system includes a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment. A first rotational assembly includes a first casing mounted to the first end of the flexible bag and a first hub rotatably mounted to the first casing. A second rotational assembly includes a second casing mounted to the second end of the flexible bag and a second hub rotatably mounted to the second casing. An elongated member has a first end coupled with the first hub and an opposing second end coupled with the second hub, the connector being flexible and having a uniform flexibility along its entire length. A first impeller is mounted to the connector.
