1、 Preparation before operation
1. Equipment inspection
Check the reliability of power grounding and confirm that the hydraulic system and cooling water supply are normal.
Verify the cleanliness of the emulsifying pot (no residue, no odor), and close all valve interfaces.
Check whether the homogenizer cutting wheel rotates flexibly and whether there is any jamming phenomenon.
2. Material pretreatment
Preheat the oil/water phase materials separately to the process temperature (usually 80 ℃± 5 ℃), filter and remove clumped impurities.
2、 Operation process
1. Vacuum pumping and feeding
Close the lid of the pot, open the vacuum valve, and evacuate to above -0.09MPa.
Inhale the pre treated oil and water phase materials into the main emulsifying pot under negative pressure.
2. Mixed emulsion
Primary mixing: Start scraping and stirring (speed 0-60rpm) to allow the material to initially blend.
Homogenization and emulsification: Open the homogenizer and increase the pressure in stages (such as 10Mpa first and then 40Mpa), and crush the particles through shear force.
Temperature control: The interlayer is heated by steam or circulated with cooling water to maintain a process temperature of ± 2 ℃.
3. Loop and completion
According to the properties of the material, cycle for 3-10 minutes and remove bubbles under vacuum.
Stop the homogenizer after reaching the target particle size, turn off the stirring, and break the vacuum.
3、 Shutdown and Cleaning
1. Discharge material
Tilt the pot body (or open the bottom valve) to discharge the finished product and avoid residue.
2. Cleaning procedures
Immediately clean the homogenization head and pipeline with clean water to prevent material solidification.
Regularly disassemble homogeneous components, scrub dead corners, and check for wear and tear.
4、 Safety precautions
1. No idling: The homogenizer must be started when the material is submerged to prevent dry grinding damage.
2. Anti scalding and anti pressure: Keep away from high-temperature surfaces during operation, and strictly prohibit opening the pot lid under pressure.
3. Parameter monitoring: Real time recording of pressure and temperature data, immediate shutdown for abnormal fluctuations.
Note: Specific parameters (such as pressure, time) need to be adjusted according to material viscosity and target particle size.
