A milk tea machine with precise ingredient dispensing
This utility model relates to the field of milk tea machine technology and discloses a milk tea machine with precise ingredient dispensing, including a machine body. A cover is threadedly connected to the top of the machine body. During use, because bevel gear three meshes with bevel gear one and bevel gear two simultaneously, its rotational power is diverted and transmitted to the inner and outer rotating rods, with bevel gear one and bevel gear two rotating in opposite directions. This reverse linkage structure causes the two sets of stirring blades to rotate in opposite directions, forming a three-dimensional shear flow field, which improves the mixing efficiency of raw materials and avoids material stratification caused by unidirectional stirring. Furthermore, the radial centrifugal forces generated by the inner and outer rotating rods at high speed are equal in magnitude and opposite in direction. The torque vectors formed by the two cancel each other out within the machine body, significantly reducing the periodic vibrations generated by traditional single-axis stirring. This not only reduces mechanical noise but also provides a reliable mechanical foundation for the milk tea machine.
