A foldable stirring cutter includes a cutter assembly rotationally disposed on a base; a bearing component detachably disposed on the cutter assembly and including a central bearing plate and equally spaced extension plates having an internally threaded connection hole; cutter components including a cutter handle, a cutter body, and a blade portion; and movable connection assemblies including a through hole through the cutter handle, an arc-shaped limiting groove in the through hole, an internally threaded limiting rod having a threaded portion on a lower portion of an outer surface and being threadedly fastened in the connection hole, and a limiting block on an upper portion of the outer surface of the limiting rod and being moveable in the limiting groove, and a limiting bolt being driven through the through hole to secure to the limiting rod. The cutter assembly folds in response to hitting a stirred material.

The present invention involves a drum assembly including a barrel having a top and a bottom. The top has a valve port and a mixer port. The bottom has a downwardly conical shape. The barrel interior storage extends from the top to the conical center of the bottom for extracting liquid from the barrel. The mixer port supports a mixer tool having a shaft with mixing paddles extending into the interior of the barrel.

There is provided apparatus (301) for mixing contents of a receptacle, the apparatus comprising a rotary shaft (302) equipped at a proximal end with a connection for removable attachment to a means of providing rotation. The rotary shaft has a mixing element (303) fixedly connected at a distal end of the shaft opposite to said proximal end. The mixing element comprises at least two arms (304) at the distal most end of the shaft, a corkscrew neck (306) on the shaft and a collar (305) on the shaft positioned in between the at least two arms and the corkscrew neck. The at least two arms are configured in a first partially-open resting position and are moveable to a second fully-open operative position. The mixing element further comprises a blade (307) positioned across the shaft more proximally than the corkscrew neck.

A fluid storage device includes a container and a torsion sensor. The container stores a fluid to be agitated. The torsion sensor has a substrate and detects torsion of the substrate. The substrate has a first end inserted in the container and a second end fixed to the container or a housing.

A fluid mixing system includes a container, such as a flexible bag, bounding a compartment. A flexible drive line is disposed within the compartment, the drive line having a first end rotatably connected to a first end of the container and an opposing second end rotatably connected to a second end of the container. At least one mixing element, such as an impeller, can be coupled with the flexible drive line. Rotation of the drive line facilitates rotation of the impeller within the container.

Apparatus for cooking foods includes an external container, an internal container, open at the top, a heating device and a rotating mixing device. The mixing device is selectively removable and comprises at least one mixing blade driven by the rotation motion.

A container (1) for a viscous liquid, in particular a colorant for paint, may comprise a stirrer (2) having a rotatable shaft (3) and a plurality of paddles (4) connected to the shaft (3). At least one of the paddles (4) and/or the connections (5) between the paddles (4) and the shaft (4) is flexible.

Disclosed in an embodiment of the present application is a mixing apparatus, mixing machine, and cooking utensil. A mixing apparatus that can be fitted to an electric motor assembly. The electric motor assembly is able to drive the mixing apparatus to rotate for mixing food ingredients. The mixing apparatus comprises a connection part, stirring rods extended from the connection part and stirring bars. The positions at which the stirring bars are fitted to the stirring rods can be adjusted based on the type and quantity of food ingredients to increase mixing uniformity.

Systems and methods for preparing construction material mixtures. A container can include a flexible body having an interior for receiving and holding construction material mixture components to be mixed. The construction material mixture components can be mixed in the interior by rotating a mixing tool. The flexible body is collapsible for forcing the construction material mixture out of a mouth of the container. The flexible body can be everted to facilitate cleaning the interior of the flexible body. The system can also include a stand, a mixing tool, a funnel, and/or a measuring cup.

A mixing device includes a base, shaft, impeller sleeve, and impeller blades. The base can be constructed for releasable attachment to an opening of a container, such as a 55-gallon drum. The shaft extends from the base and is coupled thereto such that rotation can be transmitted to the shaft by way of or through the base. The impeller sleeve is mounted on the shaft and supports the impeller blades. Each impeller blade includes an attachment leg and a stirring leg extending from the attachment leg. The impeller blades are supported so as to transition from a collapsed position with the stirring leg proximal to a central axis of the shaft to an extended position with the stirring leg distal from the central axis when the shaft is rotated. Each impeller blade can be formed of a plastic, such as a glass-filled polypropylene or glass-filled nylon.
