Abstract

The invention relates a mixer assembly for mixing liquids in a tubular container including: (a.) an electrically conductive central shaft member, (1) having a top end portion and a bottom end portion; (2) where the central shaft member is oriented longitudinally along the length of the mixing blade assembly; and (3) wherein the central shaft member is threaded along at least a portion of its circumference; (b.) a plurality of shearing members fixedly attached to the central shaft member for shearing the liquids when the shaft member is rotated; (c.) a vortex breaker member positioned below the blade members and above the bottom end portion of the central shaft member; wherein the vortex breaker member comprises: (1) a concave-shaped disk having an aperture substantially at its center, (2) wherein the central shaft member is positioned through, and fixedly attached at, the aperture of the vortex breaker member; (3) wherein the concave-shaped side of the vortex breaker member is oriented toward the bottom end portion of the central shaft member; (4) wherein all points along the perimeter of the circumference of the vortex breaker member are substantially equidistance from the center of the central shaft member.

A mixer assembly for mixing liquids in a tubular container comprising:

a. an electrically conductive central shaft member,
(1) having a top end portion and a bottom end portion;
(2) wherein said central shaft member is oriented longitudinally along the length of said mixing blade assembly;
and
(3) wherein said central shaft member is threaded along at least a portion of its circumference;
b. a plurality of shearing members fixedly attached to said central shaft member for shearing said liquids when said shaft member is rotated;
c. a vortex breaker member positioned below said blade members and above said bottom end portion of said central shaft member;
wherein said vortex breaker member comprises:
(1) a concave-shaped disk having an aperture substantially at its center,
(2) wherein said central shaft member is positioned through, and fixedly attached at, said aperture of said vortex breaker member;
(3) wherein the concave-shaped side of said vortex breaker member is oriented toward the bottom end portion of said central shaft member;
(4) wherein all points along the perimeter of the circumference of said vortex breaker member are substantially equidistance from the center of said central shaft member;
d. a stopper member for removably affixing said mixing assembly inside a tubular container, said stopper member;
(1) having threads around at least a portion of its circumference, for removably affixing said stopper member to said tubular container;
(2) having a passage substantially through its center;
and
(3) wherein said stopper member is in threaded communication with threads of an open end of said tubular containers;
e. a sleeve casing member oriented within and along substantially the same axis of said passage of said stopper member for receipt of a pair of bushing members;
f. a pair of bushing members for receipt of a spindle member;
(1) one of said bushing members disposed within and along substantially the same axis as a lower portion of said sleeve casing member;
(2) another of said bushing members disposed within and along substantially the same axis as an upper portion of said sleeve casing member;
g. a spindle member positioned within and along substantially the same axis as said pair of bushing members,
(1) said spindle member having threaded hollows at its top and bottom end portions for attachment of a coupling to its top end portion and said central shaft member to its bottom portion;
h. a coupling member,
(1) having a threaded lower portion,
(2) wherein said coupling member is in threaded communication with the threaded hollow of the top end portion of said spindle member, and
(3) a top portion of said coupling member is for removable mated connection to a corresponding coupling member attached to a gear for rotating said mixing blade assembly;
i. wherein said sleeve casing member is threaded around the circumference of an upper portion thereof;
and
j. a pressure cap member for preventing leakage of gas or liquid when said liquids are heated;
(1) said pressure cap member having a threaded hollow in a bottom portion thereof for removable attachment to the threads around the circumference of the upper portion of said sleeve casing member;
(2) wherein when said central shaft member is being rotated for mixing said liquids, said pressure cap is not attached to said sleeve casing member;
and
(3) wherein when said liquids are being heated and said central shaft member is not being rotated, said pressure cap member is threadably attached to said sleeve casing member.
