Vacuum Homogenizing Mixer
Product Overview
Our Vacuum mixing tank is a multi-functional processing system engineered for the production of high-viscosity emulsions, suspensions, and homogenous blends across pharmaceutical and cosmetic manufacturing. The Vacuum mixing tank combines three core operations - slow-speed wall-scraping agitation, high-shear bottom homogenization, and vacuum deaeration - within a single closed vessel, delivering consistent particle size reduction and bubble-free finished products. The vacuum mixing tank suitable for the pharmaceutical and cosmetic industries for the production of liquid medicines, ointments, toothpaste, cosmetic, etc.
The defining design features - hydraulic lid lifting and tilting vessel discharge - set this system apart from fixed-top emulsifiers. The hydraulic system raises the entire mixing head and lid assembly for full internal access, while the tilting cradle allows the vessel to rotate up to 120° for complete product discharge and thorough manual cleaning. This dual-mechanism design dramatically simplifies changeover, reduces product loss, and supports rigorous cleaning validation protocols required by regulated industries.

Core Structural Advantages

Hydraulic Lid Lifting System
The entire lid assembly - including the central agitator shaft, scraper blades, and all top-mounted instrumentation - elevates vertically via dual hydraulic cylinders, providing unobstructed access to the vessel interior.
• Full Accessibility: Complete exposure of internal surfaces for inspection, manual cleaning, and maintenance of seals and agitator components
• Safe Powder Charging: Open-top loading of raw materials without restrictive manhole openings, reducing dust exposure and improving operator ergonomics
• Quick Seal Replacement: Mechanical seals are fully accessible without vessel disassembly, minimizing downtime during preventive maintenance
• Controlled Descent: Hydraulic speed regulation ensures smooth, safe lowering with automatic safety locks in raised position
Tilting Vessel Discharge Mechanism
The processing vessel is mounted on a heavy-duty cradle frame with hydraulic or manual tilting capability (up to 120°), enabling gravity discharge of finished product.
- Maximize Product Yield: Complete gravity drainage of high-viscosity materials (ointments, creams, toothpaste) that resist bottom-valve discharge - product residual typically < 0.5%
- Cleaning Validation Friendly: Tilted position allows full drainage of cleaning solutions with no pooling zones; all internal surfaces are visible for swab sampling access
- Flexible Discharge Options: Direct discharge into filling machine hoppers, mobile tanks, or intermediate containers without additional transfer pumps
- No Dead-Leg Valves: Eliminates bottom discharge valves as potential contamination points and product build-up areas.


Triple-Action Mixing System
Three independent mixing systems work in synergy to achieve uniform emulsification across a broad viscosity range:
|
Mixing Mechanism |
Function |
Speed Range |
|
Anchor Scraper Agitator |
Slow-speed bulk mixing; PTFE scrapers sweep vessel walls and bottom to prevent burn-on and ensure uniform heat transfer |
10 – 60 RPM (VFD controlled) |
|
High-Shear Homogenizer (Bottom) |
Rotor-stator assembly generates 2800+ RPM shear forces; reduces particle/droplet size to sub-micron range for stable emulsions |
0 – 3500 RPM (VFD controlled) |
|
Central Disperser (Optional) |
Medium-speed turbine for powder wetting and intermediate dispersion between bulk mixing and high-shear homogenization |
0 – 1500 RPM (VFD controlled) |
Dual-Industry Process Adaptability
Pharmaceutical Applications
Engineered to meet the stringent requirements of topical pharmaceutical manufacturing:
• Ointments & Creams: Precise temperature control during emulsification phase; vacuum environment prevents microbial ingress and air entrapment
• Gels & Suspensions: Adjustable shear profiles for sensitive API dispersion without degradation; validated batch records for regulatory submission
• Oral Liquids & Syrups: Gentle mixing modes for low-viscosity solutions; CIP-compatible design for multi-product facilities
• Toothpaste & Dental Products: High-viscosity handling with silica abrasive dispersion; tilting discharge for direct transfer to tube filling lines
Cosmetic & Personal Care Applications
Optimized for premium emulsion quality and aesthetic product characteristics:
• Face Creams & Lotions: Sub-micron droplet size delivers smooth texture and skin feel; vacuum processing ensures crystal-clear appearance for transparent gels
• Shampoos & Conditioners: Controlled surfactant thickening with adjustable shear to avoid viscosity loss
• Serums & Emulsions: Temperature-ramp cooling profiles for stable crystalline structures; post-homogenization maturation cycles
• Toothpaste & Oral Care: High-viscosity mixing with abrasive and humectant incorporation; deaeration for glossy, streak-free paste
Common Production Challenges & Solutions
|
Production Issue |
Root Cause |
Our Engineering Solution |
|
Coarse emulsion / large droplet size causing unstable product, short shelf life |
Insufficient shear energy; poor homogenizer-to-bulk circulation |
Bottom-mounted high-shear rotor-stator (3500 RPM) + anchor scraper continuously feeds fresh material through the homogenizing zone |
|
Air bubbles in finished product causing packaging voids, oxidation, and texture defects |
Air entrainment during high-shear mixing; inadequate deaeration time |
Closed vacuum system (-0.08 to -0.095 MPa) operating throughout mixing cycle; controlled agitation speed to minimize vortex formation |
|
Wall build-up / burnt product at jacket heating surfaces |
Material adhering to vessel walls and overheating |
PTFE scraper blades conforming to vessel geometry; continuously wipes heat transfer surfaces during processing |
|
High product residual after discharge - yield loss and cleaning difficulty |
Bottom valve dead legs; high-viscosity material clinging to walls |
Tilting vessel gravity discharge (120° tilt angle); smooth electropolished internal surfaces (Ra ≤ 0.8μm) |
|
Long changeover times between product batches |
Difficult internal access; complex disassembly for cleaning |
Hydraulic lid lift provides full interior access; tilting vessel drains completely; tool-free seal and scraper removal |
|
Cross-contamination risk in multi-product facilities |
Hidden crevices and hard-to-clean areas |
Sanitary design with no dead legs; drainable in tilted position; CIP spray ball coverage validated; all product-contact surfaces electropolished |
