Described is a stirrer of a machine for making and dispensing ice cream products, the stirrer rotating about an axis inside a mixing and cooling cylinder and comprising: a body defining a plurality of helical scraping blades extending around the axis and acting on an inside wall of the mixing and cooling cylinder to be scraped; a shaft for rotating the stirrer about the axis of rotation; a plurality of scraping members, each designed to be coupled to a blade and equipped with elastic coupling means for the blade adapted to be elastically deformed in order to allow it to be coupled to the blade.

A scraper blade for a frozen dessert machine includes a blade body extending from a first end to a second end. The blade body includes a cutting edge on a first side of the blade body facing a scraping direction. A biasing projection extends from a second side of the blade body in a direction opposite the scraping direction of the cutting edge. A frozen product machine includes a freezing cylinder defining a longitudinal axis and a rotating beater assembly within the freezing cylinder. The rotating beater assembly includes a beater body and a scraper blade as described above. The scraper blade is operatively connected to the beater body. The biasing projection of the scraper blade biases the cutting edge against an inner diameter surface of the freezing cylinder.

A drill assembly attachment having a handle, a drill mount, and a throttle. The throttle may have a first portion and a second portion rotationally engaged with the first portion such that the second portion is rotationally actuated in response to linear actuation of the first portion of the throttle. The throttle is positioned with respect to the drill mount and the handle such that the first portion may be linearly actuated by a user with a hand grasping the handle. The drill assembly attachment receives a drill assembly such that the throttle adjustably engages a trigger of the drill assembly. The drill assembly attachment or the drill assembly receives an auger or other tool and the drill assembly attachment with the drill assembly and auger or other tool is used in a method of rotating the auger or other tool.

Provided is a mixing apparatus. The mixing apparatus comprises a housing defining a primary chamber, an inlet for receiving material into the mixing apparatus, as well as an outlet for discharging material from the mixing apparatus. The housing provides within the primary chamber a plurality of rotating shafts, each rotating shaft having a plurality of flailing fixtures associated therewith.

The invention relates to a mixing and conveying system for dry mortar materials. The dry mortar materials can be obtained from a storage silo (1) through an openable closure panel (3). A pipe (17), in which a drivable screw conveyor (4) is mounted, is arranged under the closure panel (3). The pipe (17) leads into a mixing and buffer container (18), in which a coil (20) is rotatably mounted on a central axis (19). The mixing and buffer container (18) has a volume which equals at least 1.5-times the minute capacity of the pump-screw conveyor (14). It is thus ensured that the dry mortar material is mixed therein with the added water for at least 90 seconds or longer. The mixing and buffer container (18) leads into a pipe (15) at the bottom having a pump-screw conveyor (14) which conveys the mixed mortar into a hose (5). The pump-screw conveyor (14) can be allowed to run backward. The coil (20) runs continually such that the mortar is constantly agitated to prevent setting.

A stirring device includes: a stirring tank that accommodates a fluid; a fluid blade that is rotated to make the fluid flow in the stirring tank; and a stirring blade that is provided between a bottom portion of the stirring tank and the fluid blade, is rotated to stir the fluid, and includes a substantially-plate-shaped blade portion that extends from a rotary shaft of the stirring blade to a side wall of the stirring tank, in which a normal direction of a stirring surface of the substantially-plate-shaped blade portion is inclined with respect to both an axial direction of the rotary shaft and a rotation direction of the blade portion, and a blade diameter of the substantially-plate-shaped blade portion in an extension direction is between about 50% and 70% of a tank diameter of the stirring tank.

Coned augers for bulk mixers are described. The coned augers comprise first end and second end an auger post having a first end opposite a second end; fighting extending along and about the auger post, the pitch oriented to move bulk material generally from the first end toward the second end during operation of the auger; a coned section along the auger post, the coned section comprising a first cone protruding about the periphery of the auger post, the first cone having a tapered end opposite a wide end. Mixers comprising the coned augers are also described.
