What are common operational problems and their solutions?
Common issues and practical troubleshooting methods:
a. Uneven Paste Texture (Grainy/Lumpy)
Causes: Insufficient shear force, uneven addition of materials, or incomplete dissolution of thickeners.
Solutions: Increase homogenizing speed (within equipment limits); add dispersed phase slowly and uniformly; pre-dissolve thickeners completely; extend emulsification time by 5~10 minutes.
b. Excessive Air Bubbles in Paste
Causes: Vacuum level insufficient, homogenizing head not submerged, or material added too quickly.
Solutions: Improve vacuum level (-0.08~-0.095 MPa); ensure the homogenizing head is 2~3cm below material surface; add materials slowly under vacuum; extend vacuum defoaming time.
c. Paste Segregation (Oil-Water Separation)
Causes: Inadequate emulsification, improper temperature control, or incorrect phase ratio.
Solutions: Increase shear force or emulsification time; adjust temperature to optimal range (50~75℃); optimize oil-water phase ratio; add appropriate emulsifiers/stabilizers.
d. Equipment Overheating
Causes: Long-term high-speed operation, blocked ventilation ports, or insufficient lubrication.
Solutions: Pause operation to cool the motor; clean ventilation ports; add lubricant to rotating parts; alternate between high and low speeds during emulsification.
e. Leakage (Vacuum Models)
Causes: Damaged seals, loose tank lid, or vacuum pump failure.
Solutions: Replace O-rings/gaskets; tighten the tank lid; inspect and repair the vacuum pump; check for tank body damage.
