The emulsifier is an indispensable equipment in industrial production, especially playing a key role in fine chemical industry, pharmaceutical, food processing and other fields. It mainly used to process two or more immiscible liquids (such as oil and water) into uniform and stable emulsion by physical methods. With more than 20 years of in the research, design and manufacturing of emulsifiers, Jin Zong Enterprise will introduce the main components, working principle and influencing factors of the emulsifier in detail.


Main construction of the emulsifier   Motor and transmission mechanism   Motor: As the power source, select the power according to different application needs to ensure sufficient speed and torque to drive other components of the emulsifier.   Reducer: Used to adjust the output speed of motor to meet the needs of different process conditions.   Coupling: Connects the motor and the main shaft, transmitting torque while playing a buffering and protective role.   Agitation device   Main shaft: Usually made of stainless steel, with good corrosion resistance and strength.   Impeller: The design of the impeller according to different emulsification requirements. Common types include flat blade, turbine type, anchor type and other forms to meet different shear force requirements.   Stator and system   The stator and rotor constitute the core part of the emulsifier. The precise fit clearance between the two determines the goodness of the emulsification effect. rotor forms a strong shear force field with the stator when rotating at high speed. The material is subjected to strong shear, friction and turbulent forces when passing through this area, thus emulsification.   Container   The emulsifier is usually equipped with a special reaction container to accommodate the material to be processed, and to ensure that theulsification process is carried out in a closed environment, reducing the possibility of external pollution.


Feeding and Discharge System        Including components such as feed ports, filters, valves, etc., that materials can smoothly enter the emulsification chamber and be discharged after emulsification.        Control System        The control system is responsible for monitoring the operation status the emulsifier, including functions such as speed regulation, temperature monitoring, and pressure detection, to ensure the safety and controllability of the emulsification process.        ooling System        For materials sensitive to high temperatures, the cooling system can effectively control the temperature rise during the emulsification process, preventing material deterioration. Working Principle of the Emulsifier        The emulsification process mainly relies on mechanical shear force, turbulent flow, and cavitation effects. When materials enter the emifier, they are subjected to extremely high shear force in a very short time due to the interaction between the high-speed rotating rotor and the stationary stator, causing droplets or to be rapidly broken down and reassembled into smaller units. At the same time, due to the high-speed motion of the rotor, a strong turbulent effect is produced, promoting the uniform dispersion of materials.        In addition, the cavitation effect is also an important mechanism in the emulsification process. When bubbles in the liquid are compressed their limits under high pressure, they will suddenly burst in low-pressure areas, producing strong shock waves and high temperatures, which helps to refine and emulsify the materials.        Factors Affecting Emulsification Effectiveness        Speed: Higher speeds mean stronger shear forces, which help to improve emulsification efficiency.        G between stator and rotor: Appropriate gap can optimize shear force; too small may lead to mechanical wear, while too large cannot achieve the desired emulsification effect.        Material properties: Factors such as viscosity, surface tension, etc., can affect emulsification effectiveness.        Selection of emulsifier: Appropriate emifier can reduce the interfacial tension between the two phases, which helps to form a stable emulsion.        Conclusion        In summary, the emulsifier efficient emulsification through a complex mechanical structure and precise control strategy. With the advancement of technology, the design and manufacturing technology of emulsifiers are also constantly innovating, developing more intelligent and efficient directions. For technicians engaged in related industries, a deep understanding of the working principle and influencing factors of emulsifiers is of great significance for optimizing production processes and product quality.
