Process principle and characteristics of dispersing emulsifier
Date: 2025-09-17Read: 6
A dispersing emulsifier is an instrument and equipment that achieves the mixing of multiphase substances through high-speed shearing. Its process principle and characteristics are as follows:
1、 Process principle
1. High speed shearing mechanism: By using a linear velocity of 15-40m/s between the rotor and stator of a centrifugal high-speed emulsifying head, mechanical shearing, hydraulic friction, and turbulent circulation are generated to achieve material refinement. After axial suction, the material is dispersed through steps such as centrifugal extrusion, impact tearing, etc.
2. Multi layer fixed rotor structure: The horizontal model adopts a multi-layer fixed rotor design, with a speed of hundreds of thousands of times per minute. Strong shear force and turbulence are formed through a precision gap of 0.1-0.4mm, combined with centrifugal extrusion to process materials.
3. Cavitation and homogenization: Some models (such as the SRH series) generate cavitation effects through high-speed rotor rotation, further refining droplets to the micrometer or even nanometer level.
2、 Core Features
1. Efficient mixing: The upright design ensures that materials pass through shearing, solving the problem of bottom sedimentation; The horizontal model supports fine processing at the 0.5 μ m level, suitable for continuous production in medium to large quantities.
2. Process adaptability: It can operate under normal pressure, vacuum or positive pressure conditions, with a temperature adaptability range covering -30 to 200 ℃. The chamber is made of wear-resistant stainless steel material.
3. Industry specificity: Compliant with CIP and SIP cleaning standards, suitable for high hygiene requirements fields such as food and pharmaceuticals; The laboratory model can simulate online working conditions for small-scale cyclic processing.
4. Intelligent trend: Future development directions include high shear process optimization, large-scale design, and IoT integration to achieve remote monitoring and intelligent control.
Compared with ordinary models, the fine dispersion emulsification machine can achieve smaller oil drop size (such as nano emulsion) and improve the stability of lotion by adding dispersion devices and control systems, which is especially suitable for medicine, new energy and other fields.
