Devices for treating aqueous pulps of organic materials usable in the food industry, perfumes, in the production of technical and food alcohol, in the processing of organic waste, etc., are provided. A rotary-pulsation device contains a drive, a stator, and a rotor installed in a housing. A vibration sensor is installed on an outer side of the stator to diagnose conditions of the working bodies and for continuous correction the shaft rotation speed. Reliability of the rotary-pulsation device and processing efficiency are increased by reducing manual cleaning related stops and breakage-related failures. The scope of usage is expanded because automatic processing of water pulps containing large-sized and extended fragments becomes possible; the treated pulp is saturated with small gas bubbles; and automation capabilities may be expanded when integrating the device into substrate processing systems.

A mixing agitator, for industrial use in mixing processes, that overcomes disadvantages associated with glass coated mixing agitators in the prior art. In particular, the mixing agitator includes a glass coated metal hub radially symmetrical about a central axis. The hub is at least partially embedded within a fluorinated polymer. The fluorinated polymer extends beyond the hub and forms agitator blades that may be reinforced. The hub has a centrally located receiving portion for receiving a drive shaft for rotating the agitator. The agitator is lighter weight than prior art glass coated steel agitators yet still has excellent chemical resistance and good temperature resistance. The agitator of the invention reduces likelihood of glass damage and permits agitator blade shapes not useable by glass coated agitators in the prior art. The invention also includes a mixing apparatus incorporating the hub and a method for mixing using the agitator.

A mixing machine includes a mixing head and at least one connection means for connecting a mixing container to the mixing head for forming a closed mixing container. The mixing head is pivotably mounted with respect to a frame such that the closed mixing container formed from the mixing head and container can be pivoted relative to the frame for performing the mixing process. The mixing head carries at least one rotationally-driven mixing tool. The mixing head comprises a head plate having a connecting flange molded thereon which is configured as an annular disc and comprises a planar contact surface. This contact surface has a radial extension such that mixing containers with different connection diameters on their mixing head connection side can be connected to the mixing head. The at least one connection means is configured for gripping mixing containers which differ in the diameter of their connection sides.

Provided is a highly efficient pipe-type flocculation mixer, comprising: a feeding pipe, a mixing pipe, a discharging pipe and a mixer. The feeding pipe, the mixing pipe and the discharging pipe are disposed in parallel and sequentially communicated. The mixing pipe is a circular pipe and has two blind ends. The mixer comprises a driving motor, a mixing blade and a central shaft. One end of the central shaft is coupled to the driving motor, and another end of the central shaft is coupled to the mixing blade. The size of the mixing blade enables the mixing pipe to exactly accommodate the mixing blade. Also provided is a feeding-mixing device, wherein an agent can be introduced into a hollow central shaft via an agent feeding chamber, and be sprayed out from the central shaft into a mixing chamber; said agent feeding manner enables sufficient mixing.

A stirrer for inserting into a bottom opening of a vessel bottom of a stirring vessel of an electric motor operated kitchen appliance has a plurality of positioning protrusions embodied on its circumferential surface one behind the other in the circumferential direction. A plurality of first positioning protrusions of the circumferential surface protrude with a first radial length difference beyond a smallest radius of the circumferential surface. At least one second positioning protrusion protrudes with a second radial length difference beyond the smallest radius of the circumferential surface, which second radial length difference is smaller than the first radial length difference.

Embodiments of the present disclosure include an agitating system of an agricultural system having a drive system configured to operate an agitator and a controller comprising a memory and a processor. The controller is configured to alternatingly instruct the drive system to operate the agitator in an active operation for an active time and instruct the drive system to suspend operation of the agitator for a dwell time after the active time.

A blending device (100) is provided including a blade assembly (106) having a blade coupling structure, the blade coupling structure comprising a set of blade electrical connectors (128). The blending device also includes a blender base assembly (104) having a base coupling structure, the base coupling structure comprising a plurality of base electrical connector coupler sets (130A-130C). Each base electrical connector coupler set corresponds with a coupling position of the blade coupling structure and the base coupling structure. The blade assembly and the blender base assembly are electrically coupled in a closed configuration in which the set of blade electrical connectors is in contact with one of the plurality of base electrical connector coupler sets. A method of manufacturing the blending device is also provided.

A mini mixer system includes a mixer, for executing a continuous mixing operation for an extended period of time, the mixing operation includes a mixing production process with corrosiveness, high viscosity and high mixing risks. The mixer includes a motor, a coupling and torsion meter, a reduction gear, a plurality of couplings, a frame group, a gear box group, at least one mixing element, a mixing can and a lifting mechanism group. The motor, the coupling and torsion meter and the reduction gear are connected to one another by the couplings. The reduction gear is connected to the gear box group by the coupling. The motor, the reduction gear, the gear box group and the lifting mechanism group are all fixed on the frame group. The mixer is assembled in a gear mechanism of the gear box group. The mixing can is disposed on the lifting mechanism group.

An installation for carrying out a continuous multi-stage industrial process includes a housing that defines a first space and a second space that is connected to the first through a first connecting channel. Different pressure conditions prevail in these spaces during the course of the process. A process material is passed sequentially through the first space, the first connecting channel and the second space. A transported material is provided in the first connecting channel to form a free-flowing sealing zone with the process material and ensures that different process conditions will be maintained in the two spaces, and in particular that different pressures will be maintained in the two spaces. The invention also relates to a multi-stage continuous industrial process using such an installation.
