A modular stirrer for liquid or semi-liquid food products which can be fixed to a rotary shaft of a stirring machine including a stirring element shaped in the form of a teaspoon and a fixing body, equipped with first means for coupling to said stirring element and second means for coupling to the rotary shaft.

A slurry mixer for a battery electrodecapable of maximally simplifying a configuration of a high-speed stirring body to minimize a rotational load, such that a stirring time of the slurry may be greatly reduced and productivity may be increased, preventing a powdery material from being accumulated on an upper side face and an upper surface of a low-speed stirring body, preventing a deterioration in a performance, failure and a reduction in a life span of a high-speed stirring shaft and bearing, and uniformly stirring mixed materials located at inner corners and a bottom of a container, thereby further increasing stirring efficiency.

A stirring apparatus includes a power tool such as a drill or cordless screwdriver, and a stirring bit that may be removably inserted into the power tool in the conventional manner for stirring a liquid or any other material that requires stirring or agitation for proper use or consumption. The stirring bit, in a preferred embodiment, is a generally longitudinal structure having a first and a second end, where the first end includes a hexagonal cross section, similarly to any standard drill bit, and a second end that include a clamp mechanism. The clamp mechanism is used for attaching a stirring stick or paddle to the stirring bit. In another embodiment, the stirring bit may include a beater or frothing mechanism, rather than the clamp mechanism.

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 stirring element device, in particular for mixing media with a wide range of viscosities, in particular for a polycondensation reactor, includes at least one inner stirring blade and at least one outer stirring blade which are rotatable about a common axis of rotation, wherein at least the inner stirring blade is inclined at least section-wise relative to the axis of rotation. The inner stirring blade is arranged entirely in a subregion around the axis of rotation which is equivalent to a cylinder sector with a circular sector of less than 360 as base area.

A food preparation appliance has a base, a blade member rotatable in a direction of rotation, and a container with a closed bottom, an open top and a tubular sidewall together defining an interior space of the container. The top of the container is configured for releasable connection with the base, with the blade member disposed within the interior space of the container. The sidewall has a rib projecting inward of the interior space of the container and extending lengthwise along at least a portion of the sidewall from the top of the container toward the bottom of the container. The rib has, in the direction of rotation of the blade member, a peak defined as the shortest transverse dimension measured from the center of the container to the sidewall at a respective height along the portion of the sidewall having the rib, the rib being asymmetric in transverse cross-section.

A novel device for frothing milk and corresponding method are disclosed. The frothing device preferably comprises a rotatable shaft, an impeller rotatable by the shaft, and a screen disposed about the bottom of the impeller downstream of milk being pushed by the impeller. In another embodiment, the frothing device may further comprise a pitcher having a bottom wall, wherein the rotatable shaft extends upward from the bottom wall of the pitcher. This embodiment may further comprise a heater in the base of the pitcher. In yet another embodiment, the frothing device may further comprise a pitcher having a bottom wall, wherein the rotatable shaft extends upward from the bottom wall of the pitcher. This embodiment may further comprise a housing having a heater and a nub extending upwardly from the housing. The nub is configured to engage an opening at the bottom of the shaft for rotating the shaft. The disclosed embodiments advantageously create foam and further break the foam bubbles down into microscopic bubbles resulting in a silky smooth foam-textured milk without the conventional use of a steam wand or other such device.

A helical blade body attachable to a food mixer by a shaft, the helical blade body formed from at least three helical blade members each of which has a first end connecting with a cap portion and a second end connecting with a base portion for creating a mixing zone within the helical blade body, each of the helical blade members having a spiraled configuration and extending from the cap portion to the base portion, wherein each of the helical blade members have the spiral angled in the same rotational direction, and wherein each of the helical blade members comprises a leading edge and a trailing edge with an upward facing spiraled flat surface in between with a predefined width and thickness so that during rotation of the blade body in a select rotational direction the spiraled flat surface will urge product being mixed upward, and wherein each helical blade is formed integrally with the cap portion and the base portion of a high strength plastic material. The unique shape of the helical beater described herein not only achieves higher mixing performance but also power efficiency. By using high strength plastics instead of metal, the improved helical beater design described herein will lower or fix material and manufacturing costs and will provide a better method of controlling the geometry of the beater body.
