摘要:
A driven hollow shaft carries propeller means in the form of a screw-shaped vane which at its lower edge widens to a chamber communicating through a channel with the interior of the hollow shaft and having an outlet opening through which gas supplied through the hollow shaft is discharged into a liquid in which the propeller means are immersed. The chamber is formed by two downwardly diverging screw-shaped surfaces of the vane and has a V-shaped cross section with the apex pointing outwardly from the driven shaft.

A dough mixer having a chopper section and a mixer section. The chopper section is at the inlet end of the mixer and includes a series of blades spaced longitudinally on a mixer shaft. The chopper blades are disposed in a plurality of planes normal to the shaft's axis, and extend outwardly from that shaft through a grilled floor in an inlet hopper, thereby insuring a complete and thorough break up of recycled dough. The mixer section is downstream of the chopper section and also includes a series of blades fixed to the mixer shaft. The mixer blades are also disposed in a plurality of planes normal to the shaft's axis but the mixer blades within each plane are angulated or pitched relative to that plane. Further, the mixer blades increase in pitch between succeeding planes from the inlet end to the outlet end of the mixer section, thereby insuring a homogeneous dough. The dough is exhausted from the dough mixer by gravity through an outlet port.
摘要:
A device for treating e.g. mixing of different substances comprising a vessel with a vertical axis of symmetry, at least one stirring member provided in said vessel, means provided to support the upper end of the or each stirring member, whereas drive means are provided for rotating the or each stirring member about its own axis and simultaneously about the vertical axis of symmetry of the vessel, a combined system consisting of an injection pipe and at least one pair of stirring members provided in a portion of the bottom of the vessel beyond the reach of the or each stirring member.

Apparatuses for measuring rheological properties of fluids and methods for using same are provided. In a general embodiment, the present disclosure provides a mixer sensor that is configured to be attached to a rheometer drive head and used to measure rheological properties of a fluid having particulates over a wide range of temperatures and shear rates. Apparatuses capable of obtaining rheological data of a fluid having particulates over a wide range of temperatures and shear rates provides for more precise rheological measurements. The temperatures may be very high temperatures that exceed 100° C., and the shear rates may includes a range of shear rates that are typically found in a processing pipeline system.
摘要:
A kneading apparatus has a housing and first and second rotary shafts mounted in the housing in parallel to one another for undergoing rotation about respective axes in opposite directions at unequal speeds to one another for kneading an object. The first and second rotary shafts have respective first and second stirring members arranged helically at a predetermined helical pitch and at predetermined angular pitch intervals, with the second stirring members being arranged with an inverse helix from that of the first stirring members. Side blocking plates disposed in the housing partially block the kneaded object and move it between the first and second rotary shafts. The side blocking plates are spaced apart from one another to provide a space above the first and second rotary shafts such that the kneaded object can pass through the space in the axial direction of the first and second rotary shafts.
