A hydrofoil impeller includes a central hub connected to a shaft, and being in the form of a flat plate and being perpendicular to the central axis. The central hub has first bolt holes arranged to form a pattern, the number of groups of first bolt holes corresponding to a number of blades attached to the central hub. At least three blades extend radially outwardly from the central hub, and have a group of second bolt holes arranged in a corresponding pattern to the first bolt holes so that the group of second bolt holes can be aligned with the group of first bolt holes and bolts can be placed through the first and second bolt holes to form bolted joints. The pattern in which the first holes and second holes are arranged in each of the respective groups of holes has a form of a closed curved shape.

A blade assembly for a micro puree machine including a central support hub, a cutting blade, a mixing blade, a central opening, an angled ledge and an undercut. The cutting blade extends outward from a circumferential surface of the central support hub and defines a curved leading edge. The central opening is configured to receive a power shaft therein. The angled ledge is located at an upper end of the central support hub and extends about at least a portion of an outer perimeter of the central support hub. The undercut is located on the outer perimeter of the central support hub and is positioned closer to a lower end of the central support hub than the angled ledge. The undercut includes an engagement surface that extends outwards from a central axis of the central support hub and is configured to receive and retain a clip mechanism.

A method of mixing using a tubular reactor wherein process material continuously passes through the tubular reactor which is operating at predetermined reaction conditions. The tubular reactor is rotated through reciprocating arcs about the longitudinal axis of the tube as the process material passes therethrough. Static and/or dynamic mixers or agitators may be provided within the tubular reactor.

A powdery material mixing and feeding device is configured to mix at least two types of powdery materials and to feed a compression-molding machine with the mixed powdery materials. The powdery material mixing and feeding device includes a first mixer configured to rotate about a substantially vertical shaft and to mix the powdery materials, and a reservoir configured to reserve at least a part of the powdery materials, and a second mixer configured to rotate about a substantially horizontal shaft and to mix the powdery materials.

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 compost turning apparatus may include a towable mobile base being elongated in a longitudinal direction and having a lateral direction. The mobile base may comprise a frame, a tongue mounted on the frame, one or more transport wheels mountable in a transport setup and an operational setup, one or more support wheels mounted on the frame, and a drive wheel mounted on the frame. The apparatus may also include a rotor mounted on the mobile base to rotate about an axis oriented substantially parallel to the longitudinal direction of the mobile base. The rotor may have a plurality of paddles arranged in circumferential rows, with various paddle positions and paddle orientations.

An apparatus is disclosed for mixing substances, such as paint. The apparatus includes an elongate member with a plurality of openings formed within it. A filament is threaded through the openings creating bights between openings. The bights and ends of the filament sweep through the substance when the elongate member is rotated, which works to mix the substance.

A lab stirrer comprises a housing, a stirring shaft rotatably supported about an axis in the housing and a drive to drive the stirring shaft to make a rotary movement about the axis. A blocking device is provided to block the stirring shaft against a rotation about the shaft axis.

The invention of the present disclosure is that of functional packaging systems useful for reducing the separation of solid and liquid constituents of its contents. The invention is particularly useful for preventing the undesirable separation of solid and oil phases of food products such as natural peanut butter that is manufactured without the use of undesirable additives such as hydrogenated vegetable oils, lecithin, monoglycerides, diglycerides and other substances that slow separation of the solid and oil phases from one another. In one embodiment, the invention comprises a container with a rotating base which when rotated actuates the agitation of the product contained within, as a result of the concurrent rotation of one or more axes configured with an agitator or equivalent means of stirring or mixing the contents. The invention is further provided with hermetic sealing means and the like to ensure food safety.

A device and method for aerating a food substance. The device includes: an aerator, a vessel, a drive unit and a mounting. The aerator includes a plurality of filaments attached at their proximal ends and being free at their distal ends. Every filament has a first state and a second state. The filament undergoes a reversible elastic deformation when being bent by a transverse force from the first state to the second state. The filament performs a spring-back action from the second state to the first state, lowering the spring tension, when the transverse force acting on the filament drops to zero. The aerator is attachable to and rotatable by the drive unit thereby defining an axis of rotation. The vessel defines a space for holding the food substance being bordered at the sides by an inner wall. The vessel and the drive unit are attachable to the mounting. The mounting defines a spatial relationship between the axis of rotation and the inner wall of the vessel such that the distal ends of a fraction of the filaments contact the inner wall of the vessel, wherein the inner wall bends the fraction of the filaments by applying the transverse force.
