Abstract: A blender mechanism for applying a mixing action on containerized non-homogenized products. The blender mechanism includes a housing having a drive roller and an idler roller with the rollers being mounted in spaced apart parallel relationship with respect to each other and disposed in a substantially horizontal attitude. A drive assembly is coupled to the drive roller for rotational driving thereof and the drive assembly preferably includes a variable speed electric motor which is coupled through a gear train to the drive roller.

Abstract: A mixing device for compounding polymers by elongational deformation is described. The device has a casing (1) with an inlet (2) and an outlet (3). The casing has inner walls (4) defining an enclosure (5) which communicates with the inlet and the outlet. A core (6) is arranged in the enclosure and defines a mixing space (7) between the core (6) and the enclosure wall (4). The mixing space (7) is divided into several slits (9) and chambers (10) by protrusions (8). The device is characterised in that the enclosure (5) and the core (6) are concentrically arranged around a common axis (A) and are conically tapered towards the outlet (3), and that the protrusions (8) are circumferentially arranged on at least one of the core (6) and the enclosure wall (4) with a slit gap in the range from about 0.5 mm to about 10 mm and a width of the slit gap in the range of 0 to about 5 mm. Preferably, the enclosure wall (4) and the core (6) are adjustable relative to each other for adjustment of the slit gap.

Abstract: A kneading trough for the industrial production of dough for baking bread, Viennese bakery products, pastry or the like, designed to supply a processing unit, such as a dough divider (6) having one or several vats (2, 2A) provided with a kneading mechanism (3) and a mechanism for measuring out (4) ingredients to supply the vat(s) (2, 2A) at each kneading cycle. This kneading trough (1) includes the vat(s) (2, 2A) which are are mounted tilting on a supporting frame (10) located above the dough-processing unit (6), and, furthermore, the mechanism for measuring out (4) ingredients (I1, I2, I3, I4, I5) is mounted on the supporting frame (10) above the vat(s) (2, 2A).

Abstract: The barrel (20) comprises at least two intersecting lobes (21a,21b) of cylindrical bores having parallel axes each corresponding to a screw and defining in the region of their intersection at least two longitudinal parallel edges (22). Each lobe comprises at least one shearing zone (23a,23b) adapted to cooperate with a shearing element mounted on the respective screws. The shearing zone (23a,23b) of each lobe is formed by least one groove (24a,24b) extending in the direction of the flow of the material and provided on the inner side of the barrel (20), the groove providing therebetween and each edge (22) a portion of a continuous surface of the cylindrical bore forming the corresponding lobe.

Abstract: The invention relates to a mixer in which at least one end wall and at least one part of the peripheral wall can be moved relative to one another in such a way that the interior of the mixing vessel is freely accessible from the periphery. Such a mixer is distinguished by a very good cleaning facility.

Abstract: Apparatus for use in processing radioactive waste materials for shipment and storage in solid form in a container is disclosed. The container includes a top, and an opening in the top which is smaller than the outer circumference of the container.The apparatus includes an enclosure into which the container is placed, solution feed apparatus for adding a solution containing radioactive waste materials into the container through the container opening, and at least one rotatable blade for blending the solution with a fixing agent such as cement or the like as the solution is added into the container.The blade is constructed so that it can pass through the opening in the top of the container. The rotational axis of the blade is displaced from the center of the blade so that after the blade passes through the opening, the blade and container can be adjusted so that one edge of the blade is adjacent the cylindrical wall of the container, to insure thorough mixing.

Thereafter, the kneading belt (on which the pieces of dough are carried) is periodically advanced.

Abstract: An automatic dough-producing system including a controllable mixing stage into which are fed flour and a dough-forming solution to produce a paste which is then supplied to a development stage yielding dough. In the development stage, the incoming paste is fed through a lateral inlet to a screw rotating within an elongated tube at a variable speed, the inlet position being adjustable along the screw to vary the length of that portion of the screw which acts to knead and develop the paste to produce the dough, this adjustment being independent of the mixing stage.
