A mixing apparatus includes a housing that includes a first end wall, a second end wall, and a top wall that at least partially define a cavity of the housing. The apparatus also includes a pair of rollers extending from the first end wall to the second end wall and coupled to the housing such that each roller is rotatable relative to the housing. The apparatus also includes a motor positioned in the cavity and enclosed within the housing, the motor operatively coupled to a first roller of the pair of rollers and configured to drive the first roller to rotate for rotating the container. The motor is operatively coupleable to a power source to drive the first roller of the pair of rollers.

A filtering and ventilating mechanism is driven by motors. The filtering mechanism rotates and presses downwards so its pressing surface is against a sample container. A ventilation needle is inserted into the sample container for ventilation. A mixing mechanism is arranged below the filtering mechanism and is driven by a mixing motor. The sample container is accommodated in a seat and is driven by the mixing motor. A test tube carrying mechanism is arranged below the mixing mechanism, and has an accommodating hole for a test tube. A jacking mechanism is arranged below the mixing mechanism, and is driven by a jacking motor. When the jacking mechanism moves upwards, a jacking platform is pressed against the bottom of the test tube, so that the test tube is butted against the bottom of the sample container, and a sample preparation in the sample container is dripped into the test tube.

Mixer systems 200 are provided. A representative mixer system 200 includes a power circuit 105 that powers the mixer apparatus 200; a motor 110 that is electrically coupled and powered by the power circuit 105; and a rotating structure 115 that is mechanically coupled to the motor 110, which rotates the rotating structure 115. The rotating structure 115 includes container chambers 230a,b that a container 240a,b is aligned therein, wherein the rotation of the container 240a,b mixes substances that are contained in the container 240a,b to have a homogeneous or heterogeneous mixture.

A mixer for fluid products, including a base, a support structure mounted on the base and rotatable about a first axis of rotation, and a housing structure having a housing for a container of fluid products. The housing structure is mounted on the support structure at a radial distance from the first axis, and can be rotated about a second axis of rotation which is at a radial distance from the first axis. A motor is mounted on the base for transmitting a rotational movement to the support structure about the first axis a first transmission. A second transmission transmits the rotational movement to the housing structure about the second axis. The housing for a fluid product container is at a radial distance from the second axis so as to impart, during use, a combined epicyclic movement to at least one container accommodated on the housing structure.

The mixing machine is a motorized cement mixer that designed to mix cement in batches of less than 1 cubic foot. The mixing machine comprises a mixing bucket, a paddle insert, a motor, a drive system, a housing, and a control system. The mixing bucket is used to contain the cement or concrete mixture. The paddle insert is an insert designed to go into the mixing bucket. The paddle insert further comprises a plurality of paddles that are used to agitate the concrete mixture to insure efficient mixing. The motor and drive system are used to rotate the mixing bucket to efficiently mix the concrete mixture, and to prevent the concrete mixture from setting in the mixing bucket. The mixing machine comprises a mixing bucket, a paddle insert, a motor, a drive system, a housing, and a control system.

A mixer is provided for mixing a substance in a container. The mixer includes a motor; a frame configured to be controlled by the motor to rotate on an axis; a carrier disposed at a first end of the frame and configured to hold the container; a counterweight disposed at a second end of the frame opposite to the carrier, wherein the counterweight position relative to the axis is adjustable. The mixer may be a stand-alone unit, or it may be disposed in an apparatus for dispensing a cosmetic composition.

An apparatus is provided which comprises a barrel having a substantially cylindrical configuration. The barrel comprises an exterior surface and defines an interior volume. A base unit comprises a drive motor being configured to rotate the barrel by interfacing with the exterior surface of the barrel. The barrel comprises a thermoelectric heat pump attached thereto and being controllable for at least one of transferring heat out of the interior volume and transferring heat into the interior volume.

A roller mixer system including a tube roller and a tube holder. The tube roller includes a motor and a plurality of rollers rotated by the motor. The tube holder includes a main shaft defining a shaft width and including a side, a first end defining a first width, a second end opposite the first end, and a clip disposed on the side and configured to receive a tube. The first width is greater than the shaft width. The second end defines a second width greater than the shaft width.
