High-shear emulsifying pumps possess powerful functions for comprehensively mixing, blending, dispersing, homogenizing, and emulsifying materials. Utilizing four-stage high-speed dispersion and homogenization technology, these pumps can instantly and uniformly disperse and emulsify the materials to be processed within a short period. Through high-frequency recycling, stable and high-quality products are obtained. Now, let's delve into the key points for selecting a high-shear emulsifying pump!

The high-shear emulsifying pump adopts an upright design, allowing all materials to enter the dispersion chamber, meeting process and fluid mechanics requirements, and enhancing production efficiency. The low-outlet material design complies with production requirements, making the machine operate more stably under vertical pressure and facilitating cleaning. Fully considering FDA and EHEDG standards, the materials in contact with ERS2000 are selected according to production requirements, using SS316 steel or more acid and alkali-resistant Hastelloy alloy, significantly enhancing wear resistance and corrosion resistance, and preventing contamination of equipment and materials due to physical and chemical changes. It adopts a three-layer cartridge mechanical seal design, which is quick to install and highly reliable, suitable for the pharmaceutical industry. According to pharmaceutical specifications, the dispersion chamber and outlet are surface-treated with high-quality surface treatment and no-dead-end design, facilitating cleaning and complying with CIP and SIP cleaning standards.

From the perspective of high-shear emulsifying pumps, factors affecting dispersion and emulsification effects include:

       1.The structure of the high-shear emulsifying pump. High-shear emulsifying pumps are generally divided into batch emulsifiers and inline emulsifiers. Inline emulsifiers provide better emulsification effects, with materials fully dispersed and emulsified, resulting in high efficiency. IKN high-shear emulsifiers utilize inline emulsification methods.

       2.The shear speed of the high-shear emulsifying pump. The core parameter of high-shear emulsifying pump equipment is shear speed. Generally, the higher the shear speed, the better the dispersion and emulsification effect, although this is also determined by specific material processes. IKN emulsifiers use belt acceleration with a low speed of 99,000 rpm, which is three times the domestic emulsifier speed, and a high speed of up to 21,000 rpm.

       3.Processing time. The longer the material stays in the chamber, the better the corresponding dispersion and emulsification effect. The more processing cycles, the better the general dispersion and emulsification effect. The structural design of IKN emulsifiers adopts a vertical split structure with short operating times.

       4.The precision of the emulsifying head. Traditional high-shear emulsifying pumps use single-layer emulsifying heads with rough processing, while IKN nano-homogenizing emulsifiers use three-step emulsifying heads with smaller gaps, higher precision, and better emulsification effects.

High-shear operating process:

       1.Under the centrifugal force generated by the high-speed rotating rotor, the material is axially suctioned into the working chamber simultaneously from the upper and lower feed areas of the working head.

       2.The material is radially thrown into the narrow and precise gap between the stable rotors through strong centrifugal force. Simultaneously, due to centrifugal extrusion, collision, and other forces, the material is initially dispersed and emulsified.

       3.The outer end of the high-speed rotating rotor generates a linear speed of at least 15m/s, up to 40m/s, forming fluid shear, liquid layer friction, and collision fracture with strong mechanics, allowing the material to be fully dispersed, emulsified, homogenized, and crushed while being ejected from the stator slot. The emulsifier shears, disperses, and collides materials through the high-speed rotation of the homogenizing nozzle connected to the engine. This makes the material finer and promotes the fusion of oil and water. Emulsifiers are used in the food industry for sauces, juices, etc., and in petrochemicals, paints, coatings, inks, etc., for mixing, stirring, dispersing, homogenizing, emulsifying, and grinding applications in experimental or industrial production processes.

       4.As the material is continuously ejected at high speed radially, it changes direction under the resistance of the material itself and the container wall. Simultaneously, under the action of the upward and downward axial suction force generated in the rotor area, two strong overturning turbulent flows are formed. The material undergoes several cycles to complete the dispersion, emulsification, and homogenization process.

Key points for selecting a high-shear emulsifying pump:

       1.Clarify the desired effects and purposes of using the equipment.

       2.Thoroughly understand and grasp the properties of the materials being studied, including their physical and chemical properties.

       3.Select the equipment mixer based on the materials.

       4.Reconfirm the equipment operating parameters and structural design.

       5.Comprehensively consider the equipment cost.
