Vacuum Mixer Homogenizer Paste Mixing tank Electric Heating Stirring Pot Stainless Steel Liquid Soap Making Machine

Core Components & Key Features

1. Stainless Steel Paste Mixing Tank – Durable & Hygienic

• Material: Constructed from 304 stainless steel (optional 316L for high-corrosion resistance), meeting food-grade and cosmetic-grade hygiene standards. The smooth inner surface prevents residue buildup and is easy to clean, reducing cross-contamination risks.
• Capacity Options: Available in 50L, 100L, 200L, and 500L variants to match different production scales—suitable for small-batch testing (e.g., 50L) or daily mass production (e.g., 500L).
• Structural Design: Equipped with a sealed lid (compatible with the vacuum system) and a tilted discharge port for easy, residue-free product collection. The tank’s thickened wall ensures heat retention during the heating process, improving energy efficiency.

2. Electric Heating Stirring Pot – Precise Temperature Control

• Heating Method: Electric heating with a jacketed tank design, enabling uniform heat distribution across the tank wall. Avoids direct contact between heating elements and raw materials, preventing local overheating (a common cause of soap ingredient degradation).
• Temperature Range & Accuracy: Adjustable temperature from 20°C to 120°C, with a digital display and PID control system for precise regulation (±1°C). Ideal for melting solid ingredients (e.g., sodium laureth sulfate, waxes) and maintaining optimal temperatures for chemical reactions (e.g., saponification).
• Stirring Mechanism: Equipped with a dual-impeller stirring system (anchor + paddle) that ensures full mixing of viscous liquids. The anchor impeller scrapes the tank wall to prevent material sticking and burning, while the paddle impeller creates radial flow for uniform blending of ingredients.
• Safety Features: Built-in over-temperature protection and automatic power-off function—shuts down the heating system if temperatures exceed the set limit to avoid equipment damage or safety hazards.

3. High-Shear Homogenizer – Uniform Texture & Stability

• Homogenization Principle: High-speed rotor-stator assembly (1,500–10,000 RPM adjustable) generates intense shear forces to break down agglomerates (e.g., undissolved powder ingredients) and emulsify immiscible components (e.g., oil and water). Ensures liquid soap has a smooth, non-grainy texture and long-term stability (prevents phase separation during storage).
• Homogenizer Position: Mounted on the tank lid for vertical immersion, with adjustable depth to accommodate different liquid levels. Suitable for both low-viscosity (e.g., liquid hand soap) and high-viscosity (e.g., body wash with thickeners) formulations.

4. Vacuum Mixer System – Foam Reduction & Quality Improvement

• Vacuum Function: Reduces air pressure inside the tank to ≤ -0.095 MPa, effectively removing air bubbles generated during mixing and homogenization. Eliminates foam in the final product—critical for liquid soap, as foam can affect appearance, texture, and shelf life.
• Vacuum Control: Equipped with a vacuum gauge and one-way valve to maintain stable vacuum pressure. The system works in sync with the stirring and homogenization processes, ensuring continuous deaeration without interrupting production.
