Description

TECHNICAL FIELD

[0001] The utility model relates to domestic milk making technical field, concretely relates to a milk separator. BACKGROUND

[0002] A milk separator is a dairy product processing equipment, which is usually used to separate the fat in milk, so as to obtain milk or dairy products with different fat contents. The milk separator separates the fat in milk by centrifugal force, which usually consists of a separation pump and an electric motor. The milk is sucked into the separation pump, and then the separation pump starts to rotate at high speed to generate centrifugal force. Since the fat has a higher density than other components (such as protein and lactose), it will be pushed to the middle position of the separation piece in the separation pump, thereby separating the fat, and the milk will be pushed to the periphery of the separation pump. The separated milk and fat will be discharged through different outlets.

[0003] For example, the Chinese utility model patent application No. 201220412573.1 (authorized announcement No. CN 202750552U) discloses a milk separator, which includes a base, a motor, a milk basin, a middle seat, a top seat, a cream tank, a milk tank and a separation assembly. The top seat has an upper cavity and a lower cavity, and the partition plate between the upper cavity and the lower cavity has a flow guide hole and is provided with a flow guide pipe in communication with the flow guide hole. The flow guide pipe is located in the lower cavity and is in communication with the top of the separation assembly. The milk basin is arranged on the top of the top seat, and the middle part of the milk basin has a liquid guide hole. A switch valve is arranged on the liquid guide hole of the milk basin. The switch valve includes a valve body, a valve core and a valve rod. The valve body has an axial valve core cavity and a radial liquid inlet channel. The lower end of the valve core has a lower opening flow guide cavity and a radial liquid inlet hole. The valve core is rotationally connected with the valve core cavity.

[0004] However, such a milk separator device also has problems. Since the milk separation mechanism is arranged on the top of the separator body, and the driving motor for driving the milk separation mechanism to separate the milk is installed in the separator body, the output end of the power output shaft of the driving motor passes through the top of the separator body and is connected with the milk separation mechanism, so as to assemble all the components into a complete milk separator. In the above-mentioned milk separator, since the power output shaft of the motor and the separation mechanism are hard connected, the whole body will be severely shaken due to the vibration of the driving motor during operation, thereby destroying the balance and stability of the cooperative operation of the motor and the separation mechanism, and also causing a particularly large noise during operation. In addition, the hard connection between the power output shaft and the separation mechanism does not have a buffer space between them, which will reduce the service life of the motor and the separation mechanism if they are frequently subjected to impact load.
