Described herein is a mixing apparatus for mixing a non-homogenized food product contained within a container. The apparatus includes a housing including 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, and a battery positioned in the cavity and enclosed within the housing, the battery operatively coupled to the motor to provide power thereto to drive the first roller.

A mixing device for cylindrical jars, the device having two drive rollers and two guide rollers extending upward from a housing and through a top surface of the housing. The rear end of the top surface has a stop member. The drive rollers on one side of the jar and the guide rollers on an opposite side of the jar are mounted on axles positioned in the interior of the housing, wherein the axles slant downward 2 to 45 degrees from the front end to the rear end of the housing. A motor and transmission in the housing are connected operatively to the drive rollers. The drive rollers will rotate the jar at least 5 RPM with the jar tilted downward. Ajar of natural peanut butter rotated for 5 to 20 minutes will remain uniformly mixed for a week.

A mixing apparatus includes a motor. A first plate is connected to the motor. The first plate includes a spiral groove. A second plate is disposed on the first plate. The second plate includes a first surface and a second surface opposite to the first surface. The second plate is disposed on the first plate. A plurality of clamping posts is disposed on the second plate. Each of the plurality of clamping posts is connected to the spiral groove through the second surface of the second plate, and the plurality of clamping posts is configured to guide and secure a vessel to a center of the first surface of the second plate, by rotating the first and second plates with respect to each other. A content of the vessel is mixed by rotating the first plate, the second plate, and the vessel about their respective centers.

An apparatus is provided that is configured to be used with a container having contents to permit mixing of the contents of the container. The apparatus includes a main body having a geometrical shape having an open end, a closed end, and a longitudinally extending bore or opening extending from the open end to the closed end. The opening or bore is configured to receive at least a portion of a container. A shaft is generally orthogonally positioned from a portion of the closed end. The shaft is configured to be received by a rotational device. The mixing apparatus can be used to mix various sized containers containing contents having one or more materials to be mixed.

A container assembly with improved mixing dynamics for mixing substances in preparation for injection by an injection device or for the dispersion of additives in the collection and analysis of biological samples is disclosed. In one configuration, the container assembly includes a first mixing element protruding into an interior of a container. With the container rotated about its longitudinal axis, the first mixing element forms at least one vortex which effectuates mixing of a first substance provided within the container interior and a second substance provided within the container interior.
