A rotary machine for acting on a process fluid includes an impeller, a shaft, a drive, a seal and a flush casing. The impeller acts on the process fluid and is mounted on the shaft. The drive is connected to the shaft and rotates the shaft and the impeller about an axial direction. The seal has a sealing element sealing the shaft during rotation of the shaft. The flush casing receives a flushing fluid for flushing the sealing element, and delimits an annular flush chamber extending about the sealing element. The flush casing includes a bushing surrounding the sealing element and delimits a radial leakage gap arranged between the sealing element and the bushing. The bushing delimits an axial leakage gap between the impeller and the bushing, and the width of the axial leakage gap in the axial direction is adjustable.

A carbonated beverage apparatus includes a freezing cylinder for receiving a mixture, and a stirring pusher disposed inside the freezing cylinder for pushing and mixing the mixture from an inlet of the freezing cylinder to an outlet thereof in a spiral manner, wherein the mixture is removed from the inner wall of the freezing cylinder radially back into a center portion of the freezing cylinder by the stirring pusher.

A direct contact steam injection heater that allows shear to be adjusted by modifying a lateral position of a movable combining tube. The movable combining tube includes a rack on an outer surface of the combining tube that engages a movable lever arm of an adjustment mechanism. The pivoting movement of the lever arm moves the combining tube in a lateral direction to adjust the shear in the product being heated. The combining tube is supported in a housing by a pair of lateral bushing and a pair of end seals prevent product from entering the combining tube housing. The lever arm is coupled to a worm gear shaft such that rotation of the worm gear shaft creates pivoting movement of the lever arm and lateral movement of the combining tube.

A sanitary mixing tank steady bearing is replaceable without lifting a mixing tank shaft. The steady bearing is insertable into and removable from the bottom of a bearing support attached inside the base of the sanitary mixing tank. The steady bearing may thus be replaced by a service technician working through a man way/man hole on the top of the tank allowing service without lifting the mixing tank shaft. Gaps are provided between the bearing support and steady bearing allowing flushing material from around the steady bearing to easily maintain a sanitary environment.

A device made of a temperature control device (1) and a stirring head (2), wherein the temperature control device (1) comprises an adapter (3), and the adapter (3) comprises an outer adapter surface (7), an adapter interior (8) with an inner adapter surface (9), and a temperature control element (10) for heating the adapter (3) to an operating temperature, and wherein the adapter (3) is open on a face side toward the adapter interior (8), and the stirring head (2) has a bearing hub (4) with an outer bearing hub surface (5), an inner bearing hub surface (6) and a bearing bush, and the bearing bush is positively fitted into the bearing hub (4), while abutting the inner bearing hub surface (6), and wherein the adapter interior (8) is designed for accommodating the bearing hub (4), with the outer bearing hub surface (5) abutting the inner adapter surface (9) essentially completely.

A carbonated beverage apparatus includes a freezing cylinder for receiving a mixture, a beater device disposed inside the freezing cylinder for pushing the mixture in a spiral manner from an inlet of the freezing cylinder to an outlet thereof, and a baffle supporting arrangement positioned surrounded by the beater device, wherein the beater device is rotatable to remove the mixture from an inner wall of the freezing cylinder radially back into the freezing cylinder and to stir the mixture via the baffle supporting arrangement before flowing out of the outlet.

A dual centrifuge (10) embodies the following: a driveshaft (16), a rotor (20), which is mounted on the driveshaft (16) and which can be removed axially in a removal direction (E), for a dual centrifuge, having at least one rotational unit (30); an opening (18) in the rotor (20), wherein an end region (16a) of the driveshaft (16) at least engages into said opening; and an additional drive mechanism (32) for the rotational unit or the rotational units (30). The dual centrifuge additionally has a design for operating various additional types of rotors; however, only one rotor (20, 40, 50) can be arranged on the driveshaft (16) at all times. The various rotor types (40, 50) are also adapted to the additional drive mechanism (32) for the rotational units (30) such that the function is not adversely affected. A design for operating at least one angular head rotor (40) and a swing-out rotor (50). For this purpose, the driveshaft (16) and the various rotor types (40, 50) are adapted to each other. The bearing (16), the driveshaft (16), and the various rotor types (40, 50) are adapted to one another such that each non-dual rotor (40, 50) has a geometry that is measured such that when the rotor (40, 50) is mounted, a drive device (32a) of the additional drive mechanism (32) for the rotational units (30) is arranged so as to not contact the mounted rotor (40, 50).

A chemical mixer tool for use in a storage drum is described. The chemical mixer tool typically comprises a mixer housing assembly in which one end of a mixer shaft is secured, the distal end of the mixer shaft having at least one collapsible impeller assembly removably attached thereon. The chemical mixer tool is configured to be removably secured to the top portion of the storage drum, with the distal end of the mixing shaft extending into the interior of the storage drum.

A blender with a blending assembly is shown and described. The blender may include a container and a blending assembly attached thereto. The blending assembly may include a blade, an axle, and a thick, molded bearing mount. The bearing may include a stiffening portion and a thick molded portion. The blending assembly may include a vibration dampening member. The vibration dampening member may be positioned to isolate the bearing mount and/or a bearing housing from other components.

A sanitary mixing tank steady bearing is replaceable without lifting a mixing tank shaft. The steady bearing is insertable into and removable from the bottom of a bearing support attached inside the base of the sanitary mixing tank. The steady bearing may thus be replaced by a service technician working through a man way/man hole on the top of the tank allowing service without lifting the mixing tank shaft. Gaps are provided between the bearing support and steady bearing allowing flushing material from around the steady bearing to easily maintain a sanitary environment.
