The bread machine has single mixing blades and double mixing blades. That's good
Double blade speed is relatively low, the power and torque is moderate, mixing amount is not too much, do not need high speed and high torque motor, the output power balance, low speed can reach the effect of high speed single blade, mechanical wear small, self generated heat is small, but the process is complex, the leaf structure was not strong. Short service life, easy to break, high cost.
The leaf will have higher power output, the mixing amount of force is large, but the need for high power motor, output torque will not balance, is easy to damage the shaft, but also more prone to heat, but the processing is simple, the leaf structure is solid, so the blade has long service life and low cost.
Each has advantages, disadvantages, and individual specific requirements to choose the appropriate style.
