Abstract:
The invention relates to a rotary shaft for processing foodstuffs, the rotary shaft has a rotation axis and the rotary shaft comprises at least one tool which extends along the rotation axis. The tool has an airfoil profile such that the tool comprises a leading edge, a trailing edge, an upper surface and a lower surface. Further, the tool comprises at least one fluid channel between the mean camber line of the airfoil profile and the upper surface of the tool.
Abstract:
The invention relates to a device for mixing and/or kneading food products. The device is provided with at least one container having a container inlet and, spaced therefrom, a container outlet, and at least one rotary shaft extending substantially in the longitudinal direction of the container between the container inlet and the container outlet. The shaft is provided with a mixing and/or kneading element for mixing and/or kneading the food products substantially in a continuous manner. In the container, an operative space is formed between the container inlet and the container outlet, where mixing and/or kneading of the food products is to take place. According to the invention, the device is provided with pressure means for adjusting the pressure in the operative space, and with pushing means for at least partially forming a sealing wall of the operative space with the food products to be mixed and/or kneaded.
Abstract:
A machine for producing and dispensing liquid or semi-liquid consumer food products, comprising: a tank (2) for holding a liquid base product; a treatment circuit (10) for said liquid base product, so as to obtain a liquid or semi-liquid food product; means (30) for dispensing said food product; one or more actuators (40) acting on said base product, said food product and/or parts of said machine (1). At least one of said one or more actuators (40) is a brushless motor (41).
Abstract:
The application relates to a device for mixing and kneading masses (1), in particular chocolate masses, and to a method for mixing and kneading masses, in particular chocolate masses. The device comprises a kettle (2) having an inner wall (3), which at least partially emulates the outer surface of a rotational body, and a shaft (11) and at least one tool (10, 13) fastened thereto. At least one, in particular planar, deflector surface (8) is arranged in the kettle (2), the surface extending in the axial direction.
Abstract:
The invention relates to a method of clarifying and/or thickening a solution containing solids i.e. a slurry, and the apparatus for accomplishing this. Using the method and apparatus of the present invention, the flocculant to be fed into the clarification and thickening equipment is mixed evenly and with a small shear force into the slurry in the feedwell of the apparatus. The feedwell is equipped with a mixing device. The slurry is taken onwards from the feedwell evenly into the clarification tank inside the underflow layer, which enables the separation of a clear overflow solution.
Abstract:
At least one single-stage or multistage stirrer which produces not only a tangential flow component but also an axial flow field is used in a stirred-vessel reactor in connection with the preparation of polymers by liquid phase polymerization.
Abstract:
A continuous flow particulate material blender includes a tubular housing having an input on a first end of the housing and an output on a second end of the housing. A shaft is mounted for rotation within the housing and includes ribbon flighting to urge the flow of particulate material towards the output, flow bars for mixing the particulate material in the direction of the flow and retarder bars for mixing the particulate material against the flow. Located near the first end of the housing are fluid additive lines and a dry additive dispenser for supplying additives to the particulate material. An end plate is mounted on both ends of the housing. An aperture in each of the end plates receives a respective end of the shaft. Bearings mounted externally on each end of the housing support the shaft. The rotation of the shaft is driven by a motor mounted on the first end of the housing which connects to the shaft through a gearbox. Access doors along the housing are provided to allow access to the interior of the housing for cleaning purposes.
Abstract:
Lower and upper covers permanently secured together form a vial enclosing chamber in a cap assembly which encloses the top of a bone cement mixing apparatus mixing chamber having prepackaged premeasured bone cement powder. The vial contains a monomer bone cement liquid and may be glass. The vial has two valve seats in corresponding ports on opposing vial side walls sealed by a releaseably secured preferably glass valve member threaded to a nozzle attached to the cap assembly. The vial ports are aligned with a mixing chamber liquid inlet port to permit the cement liquid to flow into the mixing chamber from the opened valves. The vial may be supplied enclosed in a separate package and includes valves on a valve stem attached to the package for opening and sealing the vial. In the alternative, the vial is frangible glass and may be opened by fracturing it and retaining the fragments in the vial receiving chamber to release the liquid to the mixing chamber.
Abstract:
A self-cleaning mixer includes a cylindrical housing and a feedscrew extending longitudinally through the housing for mixing water and cement and conveying the slurry through the housing. A chute at the infeed end of the housing receives a batch of material and directs the material into the housing. The feedscrew turns on a hollow shaft including a plurality of outwardly directed nozzles along a portion of the length of the shaft. The housing includes a plurality of inwardly directed nozzles fed from a pair of manifolds. During a cleaning cycle, one of the manifolds is shut off, thereby increasing the water pressure in the other manifold and increasing the force of the spray to enhance cleaning. The housing is slightly inclined to provide gravity feed of slurry in addition to the feedscrew.
