The present invention relates to a stirring rod of hot and cold foods supplying machine and an assembled stirring unit thereof. The assembled stirring unit includes an assembled piece and a stirring blade, wherein a length direction of the assembled piece is an axial direction, a direction perpendicular to the axial direction is a radial direction, and the assembled piece has a first joining piece and a second joining piece respectively at two ends thereof in the axial direction. The stirring blade is provided on the assembled piece and extends towards the radial direction, and the stirring blade is twisted at an angle by having the radial direction as an axis. The stirring rod is formed by serially connecting multiple assembled stirring units along the axial direction.

A reactor is described. The reactor comprises a housing having a reaction space to accommodate a reactant; an outlet pipe connected to a lower part of the reaction space; a rotating shaft disposed in the housing; and a plurality of stirring blades mounted on the rotating shaft. The housing has a lower converging region, and a cross-sectional area of the lower converging region decreases toward the outlet pipe. At least one of the plurality of stirring blades is located in the lower converging region. The outlet pipe includes a first region connected to the lower converging region and a second region extending from the first region in a discharge direction, a cross-sectional area of the first region decreases in a direction from the lower converging region toward the discharge direction, and the second region has a constant cross-sectional area.

Stirrer (1) for stirring molten glass (16), whereby the stirrer (1) comprises a shaft (2) having a tip (4) and having a central longitudinal axis (L), and one or more inner stirrer blades (5,6) which are attached to the shaft (2), and one or more outer stirrer blades (7,8) which are attached to the shaft (2), whereby the inner stirrer blades (5,6) are attached closer to the shaft (2) than the outer stirrer blades (7,8), whereby, when considering the stirrer in a cylindrical coordinate system (11), both the one or more inner stirrer blades (5,6) as well as the one or more outer stirrer blades (7,8) are disposed at an angle (, ) to the central longitudinal axis (L), whereby said angle (, ) is between 0 and 90 not including these values, and are disposed having a least a blade section with a normal vector (N, P, Q, R), on the side directed towards the tip (4), with an angular component (N.sub.A, P.sub.A, Q.sub.A, R.sub.A).

The solution proposed by the present invention consists of the different shape of the bottom of a horizontal digester (1) having at the terminal part of its length (the end side), at the opposite end from the feed inlet side, a sediment separator (9) which is in the shape of a conic pyramid (91), a linear V (92), or a mixed form (96), which is emptied periodically, allowing the removal of the sediments deposited on the bottom. In the conic pyramidal sediment separator (91) the emptying occurs by gravity through a controlled valve (93), while in the V-shaped linear sediment separator (92) or the mixed-form sediment separator (96) the emptying is by means of a helical impeller (94) at the bottom. The sediment separator allows the use of an organic fraction of municipal solid waste coming from a less sophisticated selection process with a greater presence of residual inorganic waste.

According to one aspect, a method of producing a product having mixed constituents comprises the step of providing a mixing apparatus including a main housing having an inlet and an outlet opposite the inlet wherein the outlet is disposed at a lower portion of the main housing, a mixing drum disposed in the main housing wherein the mixing drum includes an opening that is movable between a first position aligned with the inlet and a second position aligned with the outlet, and an agitator disposed inside the mixing drum. The method further includes the step of providing first and second materials, positioning the mixing drum at the first position, and introducing the first and second materials into the mixing drum through the aligned opening and inlet. Still further, the method includes the steps of operating the agitator to mix the first and second materials to produce a human-edible product, moving the mixing drum to the second position, and removing the human-edible product from the mixing drum through the aligned opening and outlet. A mixing apparatus is also disclosed.

A liner element for lining a vertical grinding mill agitator including one or more primary mounting portions configured to releasably mount the liner to a shaft of the agitator; and one or more secondary mounting portions configured to releasably mount one or more wear members to the liner. A liner segment including the liner element and at least one wear member is also disclosed.

Methods and mechanisms for mixing and dispensing multipart materials is provided. The methods and mechanisms may be used for mix on demand operations as well as for encapsulation of electronic components. The methods and mechanisms may incorporate a mixer assembly from which material is substantially directly dispensed. The methods and mechanisms may incorporate mix on demand where first and second material supply sources include pumping arrangements for pumping first and second materials through a mixing arrangement. The pumping forces provided by the pumping arrangements also provide the force to dispense the mixed material where it will ultimately be formed, such as a potting location or a mold.
