The invention relates to a device for producing a multi-component mixture, comprising a mixing chamber and a mixing device, wherein the mixing device has a stirrer which is arranged in the mixing chamber and which is rotatably driven about an axis of rotation L, wherein a temperature control channel system for controlling the temperature of the stirrer and through which a temperature control medium can flow is arranged inside the stirrer.

The invention relates to a device for producing and processing a multi-component mixture, the device comprising a mixing chamber which has an outlet, wherein the device has a closure element which can be moved in the direction of a longitudinal axis L of the mixing chamber in order to open or close the outlet of the mixing chamber; wherein the device has an apparatus for controlling an axial speed of the closure element, the apparatus comprising: a hydraulic system in which a hydraulic fluid is guided; a cylinder which is connected to the nozzle closure element and cooperates with at least one chamber of the hydraulic system; and a controllable throttle gap arranged in the hydraulic system.

The invention relates to a method in which a polyester melt containing one or more polyesters is produced, the polyester melt being foamed by a blowing agent and a foamed granulate is produced from the foamed polyester melt. The intrinsic viscosity (IV) of the polyester melt is reduced by the blowing agent about at least 0.05 dl/g, measured according to ASTM D4603, and the IV of the foamed granulate is then increased by means of a solid phase polycondensation (SSP).

Device and method for dispersing solids, liquids and gases in an extruder, having at least one shaft (1) and one housing (2), wherein at least one disk (4) with recesses is attached to the shaft, which at least one disk co-rotates with the shaft, and a non-co-rotating disk (3) is arranged immediately adjacent to the disk either in a product flow direction or counter to the product flow direction, which non-co-rotating disk likewise has recesses, and wherein the co-rotating disk is connected to the rotating shaft and has a gap (14) with respect to the housing, and the non-co-rotating disk is connected to the housing and has a gap (15) with respect to the rotating core shaft.

A mixing device includes a first feed opening for a first liquid—preferably gas-laden—plastics component, a second feed opening for a second liquid plastics component, and a discharge opening for discharging a mixture of the first and the second liquid plastics component. The mixing device has a rotating agitator for mixing the first and second liquid plastics components, and a gap remains between the agitator and the discharge opening. An adjustment device is provided which either varies the gap by a relative movement between the discharge opening and the agitator, or varies the size of the discharge opening. A regulating device is connected in signal-transmitting fashion to a sensor for determining a pressure prevailing in the mixing device. The regulating device sets the gap, or the size of the discharge opening, by the adjustment device such that the pressure prevailing in the mixing device has a predetermined value.

A liquid polymer or chemical activation system, having a chamber; a top cover plate, a middle cover plate and a bottom cover plate; wherein such configuration creates a hollow space inside the chamber that is flanked by the top cover plate and the bottom cover plate; a hybrid pump blending reactor having a progressive cavity pump and one or more inlets for receiving first and second substances; an upper multistage mixing cup configured to receive the first and second substances from the hybrid pump blending reactor; at least one high shear mixer for mixing the first and second substances; at least one submersible actuator for actuating the high shear mixer; an intermediate blending section for receiving the mix of first and second substances from the upper multistage mixing cup; a lower multistage aging cup for further mixing of the first and second substances; and at least one outlet on the bottom cover plate for releasing the mix of first and second substances.

The invention relates to continuous methods for compounding and applying adhesives, characterized in that (i) a base component of the adhesive is mixed continuously with at least one aggregate so as to produce a compounded adhesive; and (ii) the adhesive compounded in this manner is applied to a substrate. The invention also relates to such methods where a device as described here is used to carry out the method.

A hopper charged with a powder material, a screw arranged below the hopper and exposed at a supply port formed at the bottom of the hopper, and a rolling element in contact with the screw at the supply port are provided. The rolling element is larger than a space between end portions of the supply port and a screw groove of the screw.

The invention herein pertains to a device and system for controlled mixing of textured material along a linear path by means variable ohmic controls. The device comprising the following components: a dual auger unit wherein two linear augers are held within a single linear casing, each said linear augers having an increased diameter pitch along its length, perforations along the length of said single linear casing, electro-conductive plates attachable to each said perforation. The preferred embodiment of this invention is intended to be used for mixing pasta filata cheese curds to form a singular cheese mass with consistent texture. The device may also be used to mix other types of fluid textured material including food and non-food substances.
