Working Principle And Application Of Yuy-r Sanitary Emulsifying Pump

For food and beverage applications, the YUY-R sanitary emulsification pump processes materials at 960-1400 rpm, generating high shear that reduces droplets and particles to micron sizes for stable emulsions. Available in capacities from 0.5T to 13T with motor power ranging from 0.37KW to 5.5KW, this pump uses a rotor-stator system with SUS304 or SUS316L construction. The inline design supports continuous processing for dressings, sauces, dairy products, and beverages.

Rotor-Stator High-Shear Principle

Mechanical Force Generation

• The emulsifying pump contains precision-machined stator and rotor assemblies within the working chamber.

• As the rotor turns at 960-1400 rpm, centrifugal force draws product through the narrow gap between stationary stator teeth and rotating rotor teeth.

• This design subjects materials to hydraulic shear, centrifugal extrusion, impact rupture, liquid-layer friction, and turbulence.

Droplet Size Reduction Mechanism

• The emulsification pump processes materials in milliseconds as they pass through the rotor-stator gap.

• Each pass subjects the product to thousands of shear events per second.

• Droplets and agglomerates break down progressively, yielding stable emulsions and uniform dispersions.

Technical Specifications

Applications in Food Processing

• Salad dressings and sauces: the emulsifying pump creates stable oil-in-water emulsions without separation.

• Dairy products: ice cream mix, yogurt, and cream achieve uniform fat globule distribution.

• Beverages: fruit juice concentrates and protein drinks maintain consistent viscosity.

• Confectionery: chocolate and sugar syrups obtain smooth, lump-free textures.

Operational Workflow

1. Product enters the pump chamber through the inlet port.

2. Rotor spins at 960-1400 rpm, drawing material into the stator-rotor zone.

3. Material passes through the narrow gap, experiencing intense shear.

4. Processed product exits through the outlet for collection or recirculation.

5. Multiple passes refine particle size further if required.

Sanitary Design Features

• The high shear emulsifying pump features SUS304 or SUS316L stainless steel for all wetted parts.

• Electropolished surfaces of Ra ≤ 0.8 µm support CIP/SIP protocols.

• Double mechanical seals prevent product contamination and leakage.

• Modular design allows stator-rotor configuration changes for different viscosity ranges.

Maintenance and Validation

• Inspect stator and rotor teeth for wear every 500 operating hours.

• Check mechanical seal integrity for leakage or product contamination.

• Verify surface finish remains within specification after cleaning cycles.

• Validate particle size reduction efficiency using laser diffraction testing.

Engineering Value for Food Processing

The high shear emulsifying pump reduces processing time compared to conventional agitators. Continuous inline operation eliminates batch-to-batch variation, ensuring product consistency. The pump combines mixing and short-distance conveying in one unit. Capacities from 0.5T to 13T accommodate various production scales.

Proper pump selection ensures optimal emulsification results. Match capacity and power to production requirements and product viscosity.

1. Select capacity (0.5T – 13T) based on production volume.

2. Verify motor power (0.37KW – 5.5KW) meets process requirements.

3. Choose material (SUS304 for general use, SUS316L for aggressive media).

4. Confirm seal type (single for standard, double for sterile applications).

These measures ensure consistent, high-quality emulsification. Properly specified sanitary emulsification pumps deliver stable emulsions and uniform dispersions in food processing applications.

Product introduce

Santiary Pipeline high speed shearing emulsifier is of functional to smash, to refine and to mix/disperse and to emulsify the suspensions, aerosols and emulsions, efficiently, quickly and evenly.

YUY-R series In - Line high shear homogeneous pump is used in online sustained or cyclic processing elaborate materials in the narrow chamber, it is with 1 - 3 groups of coupling double rotators and stators The materials are sheared by the equal probability when through the work chamber and the granule size reduced. upgrade the effect. On - line eliminating the quantity difference between different batches, make sue the constant quality. Stator and rotator module combination make it suitable for different operating condition requirement Online measur - ement of mixing design makes the intensive production come true it has short distance low - lift transport function.

Pipeline type single - stage emulsion pump is efficient, rapid, uniform to a phase or multiple phases (liquid, solid, gas) into another immiscible continuous phase (usually  liquid) process equipment, But in typically each phase is immiscible. When the external energy input, a two material reorganization to become homogeneous. Pipeline type single -stage emulsion pump with high speed rotation of the rotor generated by high tangential velocity and high frequency mechanical effect brought about by strong momentum, so that materials in the stator rotor, narrow gap by the strong mechanical and hydraulic shear, centrifugal extrusion, liquid layer friction, collisions and turbulence integrated action, forming a suspension (solid / emulsion (liquid), liquid / liquid)and foam (gas /liquid). Horizontal pipeline type single - stage emulsion pump so that the insoluble solid phase, liquid Phase, gas rase in the corresponding ripe technology and proper amount of additive joint action falls, Instant fine dispersed emulsion, emulsion pump through frequency move in circles, finally get a stable high-quality products.

YUY-R series is a single-stage multi-layer and three-stage multi-layer sanitary shear homogeneous emulsification pump specially designed by our company for customers.

The high tangential speed generated by the high-speed rotation of the rotor and the strong kinetic energy brought by the high-frequency mechanical effect make the material flow in the narrow space between the stator and the rotor.

The gap is subjected to comprehensive effects such as strong mechanical and hydraulic shearing, centrifugal extrusion, liquid layer friction, collision tearing and turbulent flow.

Instantly fully and effectively mix and homogeneously emulsify multi-phase (solid, liquid, gas) media.

The mainstream design of the stator-rotor structure is the stator-rotor mesh type and the blade mesh type. The cutting head can be set as single circle or multiple ring, single-stage or multi-stage, and various stators and rotors can be easily disassembled and combined according to needs to obtain optimized Dispersion and mixing effects.

Application of Single-Stage Multi-Layer Emulsifying Pump in the Preparation Process of Suspensions

During the preparation process of suspensions, it is necessary to avoid problems such as precipitation and agglomeration of the main materials, and to ensure uniform sediment concentration after discharge, so as not to affect the batch quality of the finished product.

In the processing of large quantities of materials, conventional shear in-tank processing has dead angles in the dispersion system of suspensions, making it difficult to control the feeding ratio. To address such dispersion processes, Yuan En adopts a more efficient and improved solution: using the YUY En single-stage multi-layer emulsifying pump for external circulation online shear of materials, which can effectively avoid dead angles in processing, fully disperse the main materials uniformly, and ensure the uniformity of the materials.

Based on actual case data, it can be observed that with the use of the single-stage multi-layer emulsifying pump, the probability of shear for 100L of material is nearly 100%, and after two cycles, uniform dispersion can be achieved, significantly improving the efficiency of mixing and dispersion in the tank. Post-shear observation shows no agglomerated fine particles, and the liquid exhibits viscosity. The main drug is uniformly dispersed, with a particle size of around 5-10um, meeting the process requirements.
