Each blade consists of a concave surface which extends radially and has an annular sector-like shape, the projections of the upper and lower portions of the blade in the horizontal plane are two annular sectors, and the radian of the annular sector obtained by the projection of the upper portion is larger than that of the lower portion, and the annular sector-like shape and the rotation direction of blades are the same, so that each portion of the blades directly faces an incoming flow, the utilization efficiency of blades is increased and the impeller has low energy consumption and high gas-liquid dispersion efficiency. The device is efficient and energy-saving, has low power consumption, high mixing performance and high gas holdup and mass transfer performance.

A cavitation device is supplied by a disc pump with fluids for mixing. A cavitation rotor, having an array of cavities on its cylindrical surface, is fixed to a shaft for rotation by a motor. The disc pump and the cavitation device are beneficially in the same housing. At least one disc is spaced from and attached to the rotor near the inlet end of the cylindrical housing, so it will rotate with the rotor. A central hole in the (at least one) disc permits fluid to enter the space between the disc and the rotor; it is flung toward the peripheral space between the rotor and the cylindrical housing, where it is subjected to cavitation, and then passed to an outlet. The shaft may pass through one or both of the end walls of the cylindrical housing. The cavitation pump is especially useful for mixing oil field fluids.

The present disclosure discloses a yogurt maker and its method of use for using the same. A vertical upwardly extending mixing container protrusion is set at the bottom of the mixing container of the yogurt maker and a mixing head is detachably sleeved on the mixing container protrusion, and the rotation of the mixing head is driven by a power device so that the mixing head can mix the mixture in the mixing container well. At the same time, a temperature sensor is installed at the bottom of the mixing container to monitor the temperature of the mixing container, so as to ensure constant heat preservation conditions in different environments. The mixing device can be detached easily, which eliminates hygienic blind spots and ensures that the yogurt maker can be cleaned easily after making yogurt.
