Vacuum dispersing machine is a special equipment used for effective liquid mixing, dispersing and homogenizing treatment in vacuum environment. It is widely used in chemical, pharmaceutical, food, cosmetics and other industries, for the preparation of high quality suspension, emulsion, colloidal solution, etc. The following is the introduction of the principle, structure, characteristics, advantages, specific applications and core parameters of the vacuum dispersion machine:

The working principle, structure, characteristic advantage, specific application and operation method of vacuum dispersing machine

Working principle
Vacuum disperser takes advantage of the negative pressure effect in the vacuum environment to quickly remove bubbles and gases in the liquid, so as to achieve a more efficient mixing and dispersing process. It combines high-speed stirring and vacuum pumping techniques to generate shear and centrifugal forces by rotating or stirring devices to evenly disperse particles, powders or solutes in the liquid into the substrate.

Vacuum dispersing machine usually consists of the following main parts:

Dispersion chamber: Used to hold mixture and dispersion tools, usually having a sealed structure to maintain a vacuum environment.

Dispersion tools: such as stirring blades, rotating disks, etc., are used to provide shear and centrifugal forces to facilitate the mixing and dispersion process.

Vacuum system: Includes vacuum pumps and lines to create and maintain a vacuum environment.

Control system: Used to adjust dispersion speed, vacuum degree and other process parameters.

Characteristic advantage
Effective mixing and dispersion: Under vacuum environment, bubbles and gases can be quickly removed to improve mixing and dispersion effect.

Uniformity and stability: can achieve uniform dispersion and homogenization processing, to ensure stable product quality.

No oxidation reaction: under vacuum environment, oxidation reaction can be reduced to protect the stability of sensitive components.

Controllability and repeatability: Precise control of dispersion speed, vacuum and other process parameters to provide a repeatable production process.

Improve production efficiency: Reduce production time and increase productivity through high-speed mixing and dispersion.

Specific application
Vacuum dispersers are widely used in many fields, including:

Cosmetics and personal care products: preparation of lotions, cream cosmetics, emulsified perfumes, etc.

Pharmaceutical preparations: preparation of injection, oral suspension, capsules, etc.

Food and beverage: preparation of milk drinks, jams, condiments, etc.

Paints and inks: preparation of pigment dispersion, ink homogenization, etc.

Chemical engineering: preparation of colloidal solution, suspension, polymer dispersion, etc.

Core parameter
Dispersion speed: dispersion tool rotation speed and stirring force.

Vacuum degree: vacuum system pumping efficiency and vacuum degree control range.

Dispersion capacity: The volume of the dispersion chamber, which determines the amount of liquid to be processed each time.

Control system accuracy: Control system accuracy and stability to dispersion speed, vacuum degree and other parameters.

Operation method
The following is the general operation method of vacuum dispersion machine:

Preparation work:

Check the equipment: ensure that the parts of the dispersing machine are intact and the safety device is normal.

Prepare materials: Prepare liquid, solid particles or powder to be dispersed, and weigh well according to process requirements.

Prepare the container: Select the appropriate material for container loading and ensure that the container is clean and dry.

Set parameters:

Turn on the main power supply: turn on the main power switch of the disperser.

Adjust the speed: according to the process requirements, set the appropriate speed of the dispersion tool.

Adjust the vacuum degree: open the vacuum pump and set the appropriate vacuum degree according to the technological requirements.

Begin to disperse:

Pour the pre-weighed material into the dispersion chamber.

Close the dispersion chamber sealing device to ensure good sealing performance.

Start the dispersion machine: Press the start button to start the dispersion tool rotation.

Start vacuum pumping: Start the vacuum pump according to the requirements of the device.

Observe the dispersion process: pay attention to the liquid state and particle dispersion in the dispersion room.

Scattered completion:

Set dispersion time or observe dispersion effect according to process requirements.

When the dispersion is finished, stop the rotation of the dispersion tool.

Shut down vacuum pumping: shut down the vacuum pump to stop pumping air.

Open the dispersion chamber sealing device, open the dispersion chamber, and take out the dispersed liquid.

Cleaning and maintenance:

Turn off the main power supply to the distributor.

Clean dispersion chamber and dispersion tools to ensure no residue.

Check and maintain the components of the equipment to ensure their normal operation.

Replace lubricating oil and maintain hydraulic system regularly according to equipment requirements (if any).

Please note that the above instructions are a general guide and the specific procedure may vary depending on the vacuum dispersion model number and manufacturer. Therefore, before operating the device, carefully read and follow the operation manual and safety guide provided by the manufacturer to ensure proper operation and safe use of the device.
