What are the key components of a vacuum lifting emulsifier, and what are their functions?

• Vacuum System: Composed of a vacuum pump, vacuum gauge, and airtight valves. Its main function is to evacuate air from the tank to create a vacuum environment (usually -0.06~-0.095 MPa), preventing air bubbles in materials, avoiding oxidation of active ingredients, and ensuring the smoothness and stability of finished products.
• Lifting Mechanism: Including a hydraulic or electric lifting device and a guide rail. It is responsible for driving the emulsification head to move up and down stably. The lifting stroke can be adjusted according to the tank height and material level, ensuring that the emulsification head can fully contact materials of different heights and avoid dead zones.
• High-Shear Emulsification Head: The core functional component, usually a rotor-stator structure. When rotating at high speed (8,000~20,000 rpm), it generates strong shear force to break down material particles and integrate oil-water phases. The design of the rotor and stator directly affects the emulsification effect and particle size distribution.
• Mixing Tank: A closed container made of 316L stainless steel (compliant with food, pharmaceutical, and cosmetic grade standards). It is used to hold materials and provide a closed environment for vacuum processing. The tank inner wall is usually polished to Ra ≤ 0.8 μm to avoid material residue and cross-contamination.
• Stirring System: Equipped with low-speed stirrers (such as anchor stirrers or paddle stirrers) to assist in mixing materials. It can prevent local material accumulation, promote overall material circulation, and cooperate with the high-shear emulsification head to improve processing efficiency.
• Temperature Control System: Adopts a double-jacket structure outside the tank, with heat transfer media (steam or water) circulating inside. It is used to heat or cool materials to the optimal processing temperature (room temperature~120℃), ensuring the activity of functional ingredients and the stability of the emulsification process.
• Control System: Usually a PLC touchscreen control system, which can accurately set and adjust parameters such as vacuum degree, emulsification speed, lifting stroke, stirring speed, temperature, and processing time. It supports automatic operation and parameter recording, ensuring consistent processing effects between batches.
