Vacuum Emulsifying Mixer for Toothpaste & Sunscreen: Shear Force & Temperature Control Technology

1. Core Technology Overview

Jiangsu GangBen Mixer Manufacturer specializes in vacuum emulsifying mixers designed for high-precision applications in the toothpaste and sunscreen industries. Its technology focuses on two critical parameters: shear force optimization and temperature control, ensuring product stability, consistency, and energy efficiency.

2. Shear Force Technology

GangBen’s mixers utilize high-speed homogenizers (up to 3,500 RPM) combined with multi-stage rotor-stator systems to generate intense shear forces. This technology achieves:

Fine Particle Dispersion: Reduces particle size to 0.2–5 μm, critical for sunscreen’s UV-blocking efficacy and toothpaste’s abrasive uniformity.

Stable Emulsions: Prevents phase separation in sunscreen (oil-water) and toothpaste (abrasive-liquid) formulations.

Customizable Shear Intensity: Adjustable via variable frequency drives (VFD) to accommodate different viscosities (e.g., low-viscosity sunscreen lotions vs. high-viscosity toothpaste).

3. Temperature Control Technology

Precision temperature management is vital for:

Sunscreen: Maintaining 40–60°C to preserve UV filter stability (e.g., avobenzone) while ensuring smooth emulsification.

Toothpaste: Controlling 50–70°C to optimize fluoride reactivity and prevent premature gelation of thickeners (e.g., carboxymethyl cellulose).

GangBen’s mixers integrate:

Dual-Zone Heating/Cooling:

Jacketed Vessel: Steam or thermal fluid circulation for rapid heating.

Chilled Water System: PID-controlled cooling to stabilize emulsions post-homogenization.

Inline Temperature Sensors: Real-time monitoring with ±0.5°C accuracy, ensuring compliance with ISO 22716 (GMP for cosmetics) and ISO 28399 (toothpaste standards).

4. Energy Efficiency & Process Optimization

GangBen’s fourth-generation mixers reduce power consumption by 40% through:

Intelligent Vacuum System:

Maintains -0.095 MPa vacuum levels with 28% lower energy use compared to traditional pumps.

Minimizes air incorporation, reducing post-processing deaeration time.

Heat Recovery:

Recycles homogenization-generated friction heat to pre-warm raw materials, cutting steam consumption by 37%.

5. Industry-Specific Applications

Sunscreen Production:

Homogenizes zinc oxide/titanium dioxide nanoparticles without agglomeration.

Supports SPF 50+ formulations with uniform UV filter distribution.

Toothpaste Manufacturing:

Ensures homogeneous abrasive dispersion (e.g., calcium carbonate, silica) for consistent cleaning efficacy.

Prevents fluoride-thickener interactions at incorrect temperatures, avoiding product defects.

6. Competitive Advantages

Customization: Modular designs accommodate 5–3,000 L/batch capacities.

Compliance: Meets FDA, EMA, and China NMPA regulations for cosmetic and pharmaceutical equipment.

Global Reach: Exports to 30+ countries, with clients including leading sunscreen and oral care brands.

Jiangsu GangBen Mixer Manufacturer’s vacuum emulsifying mixers combine advanced shear force control and precision temperature management to deliver high-quality, energy-efficient production for toothpaste and sunscreen manufacturers. Its focus on customization, compliance, and sustainability positions it as a leader in the global cosmetic and pharmaceutical equipment market.
