The present disclosure relates to an extrusion apparatus comprising: a) a planetary roller extruder; b) a melt pump arranged downstream of the extruder; c) optionally, a fluid feeding equipment; d) a static cooling mixer equipment arranged downstream of the melt pump; e) a foaming equipment arranged downstream of the static cooling mixer equipment. The present disclosure also relates to a process of manufacturing a foamed polymeric composition and uses thereof.

A liquid analyzing device includes a carrier, a rotating plate, and a driving unit. The rotating plate rotatably connected with a pivot portion of the carrier contains a test liquid. The rotating plate or the driving unit has a stopping portion. When the driving unit drives the rotating plate to rotate so the stopping portion moves to a first position and interferes with the carrier, the driving unit applies driving force to the pivot portion of the carrier along a first rotation direction through the rotating plate. When the carrier rotates along the first rotation direction and the driving unit applies driving force to the rotating plate along a second rotation direction opposite to the first rotation direction, the rotating plate rotates relative to the carrier, the stopping portion moves to a second position and interferes with the carrier, and the driving unit applies driving force to the pivot portion of the carrier along the second rotation direction through the rotating plate.

Continuous compounding systems include a feeding section and a compounding section. Method for compounding or mixing solid matter and liquid matter include providing a continuous compounding system, adding matter to the continuous compounding system, and mixing or compounding the matter.

A size of an agitating mechanism can be reduced. An agitating mechanism according to an aspect of the present disclosure is an agitating mechanism for agitating fluid flowing through inside a pipe, including: a rotary body placed inside the pipe so as to be able to rotate in a circumferential direction of an inner circumferential surface of the pipe; and a regulation part configured to regulate a movement of the rotary body in a longitudinal direction of the pipe. The rotary body includes a hollow part penetrating the pipe in the longitudinal direction of the pipe and an agitating blade provided in the hollow part.

A production method for producing a particle mixture in which two or more types of particles are mixed, including a step of adding a first additive to first particles and mixing the first additive with the first particles using a first mixer and a step of introducing the two or more types of particles including the first particles mixed with the first additive and second particles into a blender container of a gravity blender, and mixing the two or more types of particles inside the blender container.

An extruder screw for a multi-screw extruder for plastics extrusion includes: a feeding and metering zone for melting and homogenizing the plastic and an evacuating zone for carrying away gaseous constituents and a compressing and/or discharging zone; a multi-screw section, which has a plurality of planetary screws, which lie open on the outer circumference of the extruder screw, at least over part of their length; and a driving zone, in which the planetary screws engage by way of a toothing in an external toothing on a central shaft or in an internal toothing in a stator ring or in the inner wall of an extruder bore of the multi-screw extruder. The feeding and metering zone extends into the multi-screw section, wherein the respective part of the planetary screws that is lying in the metering zone is at least partially enclosed.

A food mixer is presented having mixing tool detection capability. The food mixer has a base unit with a tool attachment portion, a mixing bowl attached to the base unit, and a motor attached to the base unit. The motor has operational settings and is configured to apply a torque to the tool attachment portion. A mixing tool is removably attached to the tool attachment portion, and a controller unit of the mixer is configured to detect the mixing tool attached to the tool attachment portion and to automatically control the operational settings of the drive motor based on the mixing tool detected. A magnet carrier may be used to detect a magnetic portion of the mixing tool as it moves with respect to a magnetically-sensitive sensor in the base unit.

Provided is a production method with which a large amount of particle mixture in which two or more types of particles are mixed can be easily produced. The production method is for producing a particle mixture in which two or more types of particles are mixed, and includes the following steps (1) and (2): (1) a step of adding a first additive to first particles and mixing the first additive with the first particles using a first mixer; and (2) a step of introducing the two or more types of particles including the first particles mixed with the first additive and second particles into a blender container of a gravity blender, and mixing the two or more types of particles inside the blender container.
