30L Bottom Homogenizer Vacuum Emulsifying Mixer | 3-in-1 Cosmetic Cream & Pharmaceutical Mixing System
The 30L Bottom Homogenizer Vacuum Emulsifying Mixer is a state-of-the-art, 3-in-1 processing system designed for the production of high-quality emulsions, creams, lotions, and pastes. This complete system includes the main emulsifying pot, an oil phase tank, and a water phase tank, enabling precise control over the entire mixing and emulsification process .
Ideal for the cosmetic, pharmaceutical, food, and chemical industries, this machine is engineered to handle high-viscosity, highly thixotropic pastes and achieve exceptionally fine particle sizes, down to the nanoscale (6nm-2um) . Its bottom-mounted homogenizer design provides a significant advantage for processing such materials, ensuring efficient particle size reduction and uniform product texture .
Core Technical Specifications
Key Features and Benefits
1. Complete 3-in-1 System
The system includes the main mixing pot, an oil phase pot, and a water phase pot . This configuration allows for the separate preparation and pre-heating of oil and water phases, which are then combined under vacuum in the main pot for final emulsification. This process is crucial for creating stable, high-quality emulsions.
2. Bottom-Mounted Homogenizer Design
A standout feature of this machine is the bottom homogenizer . Unlike top-mounted designs, the homogenizing head is placed at the lowest point of the vessel. This positioning leverages gravity, allowing high-viscosity and thixotropic materials to flow naturally into the high-shear zone for more effective particle size reduction .
3. High-Shear Homogenization
The homogenizer operates at 3000 RPM with a rotor-stator design . This high-speed shearing action subjects materials to intense hydraulic shear, centrifugal extrusion, impact, and turbulence. As a result, particles are broken down to between 6nm and 2um in size, creating a smooth, stable, and uniform end product free from agglomerates .
4. Efficient Wall-Scraping Mixing
The machine features a low-speed, all-round wall-scraping mixer fitted with PTFE scraper blades . The scraping action continuously removes material from the vessel wall and bottom, preventing dead zones and ensuring every part of the batch is uniformly mixed. The scraping speed is adjustable via a frequency converter from 10-120 RPM, allowing for process optimization .
5. Vacuum Operation
The main pot operates under a vacuum of -0.09 MPa . This is essential for several reasons:
Air Bubble Removal: Vacuum conditions immediately draw out air bubbles generated during high-speed mixing, resulting in a dense, bubble-free product.
Deaeration: Removes dissolved gases, improving product stability and appearance.
Oxidation Prevention: Protects oxygen-sensitive ingredients from degradation.
Vacuum Material Transfer: Materials from the water and oil pots can be drawn into the main pot via vacuum, reducing contamination risks.
6. Heating and Cooling Capabilities
The tank features a three-layer jacket design, allowing for both heating and cooling as required by the process .
Heating: Options include steam heating or electric heating, with automatic temperature control.
Cooling: Water cooling can be introduced through the jacket for rapid temperature reduction after processing.
7. Superior Sanitary Design
The pot body is constructed from imported three-layer stainless steel, and the tank interior and pipes undergo mirror polishing . This high-quality surface finish prevents product adhesion, is easy to clean, and fully complies with GMP standards , making it suitable for food, cosmetic, and pharmaceutical applications.
8. Flexible Discharge Options
Finished product discharge is facilitated through a bottom valve or by tilting the pot, allowing for fast, efficient, and residue-free emptying of even the most viscous materials .
Detailed Working Principle
The 30L Vacuum Emulsifying Mixer operates through a precise, multi-stage process to achieve the highest quality emulsions:
Preparation: Raw materials are weighed and loaded into the oil and water phase tanks.
Pre-Heating & Mixing: The contents of the oil and water phase tanks are independently heated and mixed to the required temperature. This ensures ingredients are fully dissolved or melted before they are combined.
Vacuum Transfer: Under vacuum pressure, the prepared oil and water phases are drawn from their respective tanks directly into the main emulsifying pot via a pipeline.
Emulsification: Once the main pot is charged and sealed, the scraping mixer begins rotating to ensure bulk mixing. Simultaneously, the bottom homogenizer starts operating at 3000 RPM.
Shearing Process: The material is drawn into the homogenizer head, where it is subjected to intense shear between the high-speed rotor and the fixed stator. This action breaks down the particles into droplets of 2-6um .
Cooling: After emulsification, the jacket is supplied with cooling water to reduce the temperature of the finished product while mixing continues.
Discharge: The final, de-aerated, and uniform emulsion is discharged from the main pot using the bottom valve or by tilting the vessel .
Applications
The versatility of the 30L bottom homogenizer vacuum emulsifying mixer makes it suitable for a vast range of products.
