vacuum homogenizer cream mixer

The vacuum homogenizer cream mixer is a device that makes liquid and gas medium forced convection and uniform mixing. The type, size, and rotating speed of the mixer influence the distribution of mixing power between the overall flow and turbulent fluctuation. Generally speaking, the power distribution of the turbine mixer is beneficial to the turbulent pulsation, while the propeller mixer is beneficial to the overall flow.

For the same type of mixer, under the condition of the same power consumption, the power of the mixer with a large diameter and low speed is mainly consumed in the overall flow, which is conducive to macro mixing. The power of the vacuum homogenizer cream mixer with a small diameter and high speed is mainly consumed in turbulent fluctuation, which is conducive to micromixing. The scale-up of the mixer is a complex problem related to the technological process. Up to now, it can only be scaled up step by step and extrapolated to the industrial scale according to the obtained scaling up criteria.

Analysis and introduction of vacuum homogenizer cream mixer selection steps

The design and type selection of the  are closely combined to mix operation. Different mixing processes need to be realized by the operation of different mixing devices. In the design and model selection, the vacuum homogenizer cream mixer type, motor power, and mixing speed should be determined according to the purpose and requirements of the process for mixing operation, and then the reducer, frame, mixing shaft, shaft seal, and other components should be selected. The specific steps are as follows:

 1.select the mixing machine type according to the process conditions, mixing purpose, and requirements. When selecting the mixing machine type, fully grasp the dynamic characteristics of the mixer and the causal relationship between the flow state generated by the mixer during the mixing process and various mixing purposes.

 2.determine the motor power, mixing speed, and agitator diameter through experimental means and computer simulation design according to the determined mixing model, the flow state generated by the mixer during mixing, and the control requirements of the process on mixing time, settling speed and dispersion.

 3.according to the motor power, mixing speed and process conditions, select and determine the reducer model from the reducer model selection table. If the reducer is selected according to the actual working torque, the actual working torque shall be less than the allowable torque of the reducer.

 4.select the frame and coupling with the same model and specification as d according to the output shaft head D of the reducer and the support mode of the mixing shaft system.

 5.the shaft seal type shall be selected according to the do size, installation space, working pressure, and working temperature of the mixing shaft head of the rack.

 6.according to the installation form and structural requirements, the structural type of mixing shaft shall be designed and selected, and its strength and stiffness shall be checked.

 7.install the bottom cover, flange base, or flange according to the nominal center size DN of the rack, the bearing type, and the pressure grade of the mixing shaft.

 8.determine whether to configure auxiliary support according to support and anti-vibration conditions.

In the above selection process, the combination and configuration of the vacuum homogenizer cream mixer device can be referred to (schematic diagram of mixing device design and selection process). During the configuration process, the key dimension of the connection between the components is the size of the shaft head. In principle, the components of the same size as the shaft head can be interchanged and combined.
