A counter-rotating dough making mechanism, including a drive shaft (9) that is provided with an upper dough hook assembly (1) and a lower dough hook assembly (2) is disclosed. The lower dough hook assembly (2) is preferably provided with a stir plate (3) which enhances the thorough mixing of flour during dough kneading. The upper dough hook assembly (1) and the lower dough hook assembly (2) are connected by gears (42a, 42b, 42c) so that they rotate synchronously but in the opposite direction. By the counter-rotating action of the upper dough hook assembly (1) and the lower dough hook assembly (2), the dough making process is more effective as compared to the usual single piece dough hook as used in many stand mixers. The design and construction of the disclosed counter-rotating dough making mechanism is simple, robust, and reliable, and can deliver superior performance in dough making.

The present invention relates to a large-scale magnetic purification system, including: a liquid storage apparatus, capable of being connected to a liquid source and a waste liquid barrel through a liquid path system; a stirring system mounted above the liquid storage apparatus, where a stirring paddle of the stirring system is inserted into the liquid storage apparatus for stirring; magnets mounted around the liquid storage apparatus; a magnet actuating mechanism for manipulating the magnets to move away from or close to the liquid storage apparatus; and a control system, connected to the liquid path system, the magnet actuating mechanism, and the stirring system and controlling the liquid path system, the magnet actuating mechanism, and the stirring system.

An apparatus for the continuous ohmic thermal treatment of a fluid product includes a conduit defining a longitudinal flow path for the product to be treated extending between an inlet and an outlet. The conduit includes a first and a second heating chamber that are disposed longitudinally along an axis and arranged in sequence, with each heating chamber including a first electrode and a second electrode, separated by an electrical insulating member. The first electrode is located near the inlet or the outlet of the conduit, and the second electrode is located in an intermediate zone of the conduit. A first and a second rotor extend into the first chamber and the second chamber, respectively, and are rotatable about the longitudinal axis. A support system is configured to support in the radial direction the first and second rotors at the intermediate zone of the conduit.

A stirring/mixing device is provided, comprising a container and a motorized stirring element that permits substances within the container to be stirred without an attendant. In a preferred embodiment, two blades are provided that are shaped to push material away from the wall of the container and fold the substances together so as to provide a substantive mixing of whatever is placed within the container. The device can be configured so that mixing is controlled by a panel or remote control and the speed and direction can be adjusted, such that proper mixing is achieved without direct supervision. To provide proper force, the blades can be attached on a gear drive that rotates about the opening of the container

A dynamic mixer for a plurality of fluid components contains a housing and a rotor element which is rotatably arranged in the housing, with the housing having an inlet opening for at least one respective component and having at least one outlet opening. A ring-shaped intermediate space is provided between the rotor element and the housing in which a mixing element connected to the rotor element is arranged. The mixing element has a vane element which is formed as a directing element for conveying the components from the inlet opening to the outlet opening. The vane element is a directing element and has a directing surface which has a concave curvature with respect to the outlet opening and is further remote from the outlet opening at the onflow side than at the outflow side.

The embodiments of the present disclosure provide a stirring and separating device for high-value components of a waste PCB and a control method thereof. The stirring and separating device comprises an insulated outer tank for accommodating a desoldering flux. The insulated outer tank is provided with a stirring mechanism. The stirring mechanism includes a main rotation shaft. A plurality of spaced cross beams are mounted at a bottom of the main rotation shaft. Each of the cross beams is provided with a secondary rotation shaft. A bottom of each of the secondary rotation shafts is rotationally connected with a stirring wheel through at least two connecting rods. At least two connection points are formed between each of the at least two connecting rods and the stirring wheel. When any one or more of the at least two connection points are disconnected, the stirring wheel rotates to a different angle.

A robot comprises an auger-based drive system, a memory, and a processor coupled with the memory and configured to control movement of the robot, via the auger-based drive system, relative to grain in a grain bin. The processor is further configured to direct traversal, by the robot, of a landing zone portion of a surface of a pile of the grain during load-in of the grain to disperse broken grain and foreign material away from the landing zone portion. The landing zone portion is located in a center of the grain bin where the grain lands as it is augured into the grain bin during load-in. The dispersal is affected in part by rotation of augers of the auger-based drive system.
