SDR Multi-Stage Continuous Emulsifier
The SDR series is a three-stage high-shear emulsifier primarily designed for the production of microemulsions and ultrafine suspensions, achieving a narrow particle size distribution. The machine chamber houses three sets of stator and rotor emulsifying heads, arranged sequentially, suitable for both recirculating and fully continuous production processes. This series offers stator and rotor head modules with various tooth profiles to precisely adapt to diverse application requirements and enable quick and easy replacement. The SDR series shares the same exceptional scalability and cleanliness characteristics of the SUTL series, and is fully compatible with CIP and SIP systems, meeting stringent production cleanliness requirements.
Product Overview
| Viscosity | ≤20,000 cps |
| Capacity | 60m³/h |
| Application Areas |
Suitable for dispersion, emulsification, and homogenization of materials in industries such as biology, pharmaceuticals, food, coatings, inks, textile auxiliaries, cosmetics, lubricants, and pesticides. (For more application areas, please click "Free Consultation") |
| Applicable Materials | It can be used in processes where solids and liquids, or liquids and liquids are mixed to form solutions, colloids, suspensions, or emulsions; it can be used for more than a thousand materials, including juices, soups, dairy products, tissue homogenates, cosmetics, surfactants, asphalt, emulsifiers, and oilfield chemicals. |
Product Advantages
-
Easy to operate
Can be used with pipe or container inlets/outlets, easy to install, with good conveying capacity, no need for additional conveying pump.
-
High efficiency and good product quality
The equipment has a linear velocity of over 23m/s, which can quickly and evenly distribute one phase into another or more phases, achieving fine homogenization, dispersion, and emulsification effects. The final product is stable and not prone to stratification.
-
High processing precision
The rotor and stator are made of forged materials and machined by CNC machining center. The rotor-stator gap is extremely small, with good shear limit fineness and high emulsification and dispersion efficiency. At the same time, nanomaterials can be sprayed to improve the service life of the product.
-
Strong non-standardization
The material can be customized according to requirements, such as SS304, SS321, SS316L stainless steel or titanium alloy and other unconventional materials; mechanical seals and pressure balance tanks can be configured to meet pressurized working conditions; explosion-proof equipment can be customized.

*The pump flow rate generated by the machine itself is calculated using H₂O as the medium, and the machine is configured with a standard emulsifier head.
Working Principle
The SDR series is a three-stage high-shear emulsifier. The working chamber contains three sets of rotors and stators, precisely fitted and matched. A motor drives the intermediate shaft to rotate at high speed, creating a vacuum between the rotor and stator. Material is drawn into the rotor-stator chamber through the inlet. The powerful kinetic energy generates extremely high linear velocity in the rotor, causing the material to undergo intense impact, crushing, centrifugal extrusion, liquid layer friction, and strong shearing between the rotor and stator before being ejected. Under the action of forces in multiple directions, strong turbulence is generated, and the material flows out from the outlet. This process instantly and uniformly disperses and emulsifies immiscible solid, liquid, and gaseous media. The equipment can undergo multiple cycles to ultimately obtain a stable, high-quality product.
