Ultrasonic Homogenizer | www.sefluid.com

An ultrasonic homogenizer, also known as an ultrasonic disruptor or sonicator, is a scientific instrument used for sample preparation in various fields, including biology, chemistry, materials science, and food technology. It utilizes high-frequency sound waves to disrupt and homogenize samples, resulting in the dispersion of particles, cell disruption, emulsification, and mixing of components.

SeFluid’s ultrasonic homogenizer series comprises a range of instruments designed to provide efficient and consistent sample processing. The series encompasses different models, each tailored to meet specific requirements of various applications. From small-scale laboratory experiments to large-scale industrial processes, SeFluid offers a comprehensive solution to meet diverse needs.

How Ultrasonic Homogenizer Works

The ultrasonic homogenizer works based on the principle of acoustic cavitation. It utilizes high-frequency sound waves to create alternating compression and rarefaction cycles in a liquid medium containing the sample. Here’s a step-by-step explanation of how an ultrasonic homogenizer operates:

  • Transducer: The ultrasonic homogenizer consists of a transducer, which is typically made of piezoelectric materials such as ceramics or crystals. The transducer is responsible for converting electrical energy into high-frequency mechanical vibrations.
  • Generator: The ultrasonic homogenizer is connected to a generator that supplies electrical energy to the transducer. The generator produces high-frequency electrical signals, typically in the range of 20 kHz to a few megahertz, depending on the specific application.

  • Probe or Horn: The transducer is attached to a probe or horn, which is immersed in the liquid medium containing the sample. The probe serves as a medium to transmit the mechanical vibrations generated by the transducer to the sample.
  • Acoustic Cavitation: When the generator is turned on, the transducer starts vibrating at the desired frequency, generating ultrasonic waves. These waves propagate through the liquid medium and create alternating cycles of compression and rarefaction.
  • Bubble Formation: During the rarefaction phase of the sound wave, microscopic bubbles form in the liquid. These bubbles are typically formed at locations with imperfections or dissolved gas in the liquid.
  • Bubble Growth: As the rarefaction cycle continues, the bubbles grow in size due to the decrease in pressure. The growth of these bubbles is assisted by the continuous supply of gas from the liquid or the diffusion of gas trapped within the liquid.
  • Bubble Collapse: When the compression phase of the sound wave arrives, the pressure increases rapidly, causing the bubbles to collapse violently. This collapse is known as acoustic cavitation.
  • Energy Release: The rapid collapse of the bubbles releases a tremendous amount of energy in the form of shockwaves, microjets, and localized heating. The collapse of the bubbles near solid surfaces can generate even higher energy levels.
  • Disruption and Homogenization: The energy released during acoustic cavitation creates mechanical forces that disrupt cells, break down particles, and promote mixing within the sample. The intense shear forces, microstreaming, and local temperature increases contribute to the homogenization process.
  • Control and Optimization: The ultrasonic homogenizer allows the user to control various parameters such as power, amplitude, and sonication time. These parameters can be adjusted based on the specific sample characteristics and desired outcomes, enabling optimization of the homogenization process.

By utilizing the phenomenon of acoustic cavitation, the ultrasonic homogenizer efficiently disrupts and homogenizes samples, leading to cell disruption, particle dispersion, emulsification, and mixing. The precise control over sonication parameters allows researchers to tailor the process according to their specific needs, resulting in effective sample preparation in various scientific and industrial applications.

Material of Ultrasonic Homogenizer

The material of the ultrasonic horn or probe can vary depending on the specific application and the manufacturer. Common materials used for ultrasonic homogenizer probes include:

  • Titanium: Titanium is a popular choice due to its high strength, corrosion resistance, and ability to transmit ultrasonic energy efficiently. Titanium probes are suitable for a wide range of applications and are often used in biological and chemical laboratories.

  • Stainless Steel: Stainless steel is another common material for ultrasonic homogenizer probes. It is durable, resistant to corrosion, and has good mechanical properties. Stainless steel probes are often used for general laboratory applications.

  • Aluminum: Aluminum is lightweight and has good thermal conductivity. Aluminum probes are suitable for applications where weight is a concern, and they are commonly used in smaller-scale laboratory setups.

  • Zirconium: Zirconium is chosen for its corrosion resistance and high-temperature stability. Zirconium probes may be used in applications where aggressive chemicals are present.

  • Plastics: In some cases, plastic materials such as PEEK (polyether ether ketone) or Teflon may be used for probes, especially in applications where chemical compatibility and non-reactivity are critical.

It's essential to choose the appropriate material based on the specific requirements of your application, taking into consideration factors such as the type of samples being processed, the chemicals involved, and the desired performance characteristics.

Horizontal Bead Mill | www.sefluid.com

Introduction of Bead Mill

The bead mill, also referred to as the sand mill, is a kind of milling equipment used for particle size reduction and dispersion of solid particles in a liquid medium. The working of a bead mill is based on intense agitation and grinding between the solid particles and the grinding media (beads) within a cylindrical chamber. The chamber is typically filled with grinding beads made of materials such as zirconia, ceramic, or metal. There is an agitator in the chamber, usually in the form of a rotating shaft with discs or pins attached. Its high-speed rotation generates a strong turbulent flow within the chamber, causing the grinding beads and the material to collide and interact.

As the material is fed into the mill from one end, it is subjected to the high shear forces generated by the agitator and grinding beads. This intense agitation breaks down the particles, reducing their size and promoting dispersion. The grinding beads effectively grind and disperse the material, ensuring a uniform particle size distribution in the final product.

Compared with similar products from other competitors, SeFluid's bead mill series are cost-effective and easy to maintain with an economic price that customers can afford but can achieve nano-level grinding fineness. In many fields such as coatings, rubber, pesticides, cosmetics, etc., SeFluid's bead mills are widely used and widely welcomed by users.

Principle of Bead Mill

https://youtu.be/6mqaXifFtTo

There are a group of cylindrical agitating rod pins installed on the hollow rotor shaft. These pins work with the horizontal ceramic shell to form a high-density energy grinding chamber. There are different materials for the pins according to different material properties. When running, the hollow stirring shaft drives the rod pins to do high-speed operation. Then, the rod pin drives the medium to carry out fierce collision and grinding. Therefore, the medium experiences strong impact force and high shear force. After that, good milling and dispersing effect will be achieved.

Advantage of SESM Bead Mill Series

Silicon Carbide Inner Milling Cylinder

Bead Mill Silicon Carbide Inner Milling Cylinder_SeFluid

In SeFluid's series of bead mill, we take silicon carbide ceramic as grinding cylinder material. It is sintered over many days at high temperatures. As the hardness of silicon carbide is second only to diamond, it is highly wear resistant and long lasting. Meanwhile, it has high strength, high hardness, excellent wear and corrosion resistance and good temperature resistance (-50℃ to 1350℃). In addition, the smooth surface of silicon carbide ceramic can prevent dust accumulation. So, it is ideal material for milling parts.

Long Life Milling Assembly

bead mill milling assembly material 3_SeFluid

Rotor assembly is one of the key parts of an agitator bead mill. It is also the final kinetic energy conversion device. Due to the high speed of rotation, the rotor assembly must be highly resistant to fatigue, corrosion and abrasion. Therefore, it is made of special materials and subjected to many rigorous tests, depending on the customer's material requirements. This ensures that our bead mill series achieves consistent and efficient grinding performance. For all SeFluid's bead mill products, we have various wear resistant materials for user's options ranging from ceramic to hard alloy.

Cartridge Mechanical Seal Adopted

Modular design is adopted in the use of cartridge mechanical seals, where the seal module is directly installed on the bead mill shaft during installation. During maintenance, only the seal module needs to be disassembled, without the need to dismantle other components such as bearings. This greatly simplifies the installation process and reduces maintenance costs.

When a bead mill is in operation, a large amount of grinding fluid is generated. If the seal is not tight, it can lead to leakage of the grinding fluid, which can affect the normal operation of the equipment and even cause safety accidents. Moreover, the grinding fluid can enter the bearings, resulting in damage to the bearings. Cartridge mechanical seals have excellent sealing performance, effectively preventing leakage of the grinding fluid, protecting the normal operation of the bearings, prolonging the service life of the equipment, and reducing operational costs.

High Efficiency Cooling Systems

bead mill cooling system_SeFluid

Good cooling is necessary to ensure the long-term stable running of a bead mill. If the large amounts of heat are not removed in time, the mechanical seal and milling parts are apt to be damaged. Meanwhile, the milled material can also change its physical or chemical properties due to the high temperature. In SeFluid's bead mill series, we have specially designed two efficient cooling systems. Firstly there is an oil circulation cooling system for the mechanical seals. Secondly, there is a jacket cooling system for the grinding cylinder. Moreover, the system allows users to keep track of the temperature rise.

Introduction of Rotary Lobe Pump

The Rotary Lobe Pump is a positive displacement pump widely utilized for various liquid transfer applications, including viscous, shear-sensitive, and abrasive fluids. Operating on the principle of rotating lobes, it creates a vacuum that draws in fluid and expels it through the discharge port. Comprised of two or more non-contacting lobes housed within a metal or rubber casing, this design minimizes wear and tear, reducing maintenance needs. Lobes can be customized with different profiles like bi-wing, tri-wing, or four-wing to optimize flow rate and pressure for specific uses.

Renowned for their efficiency, reliability, and accuracy in metering and dosing tasks, Rotary Lobe Pumps can accommodate solids up to a certain size and maintain consistent flow even with changing viscosities or pressures. Commonly found in industries such as food and beverage, pharmaceuticals, chemicals, and wastewater treatment. SeFluid's rotary lobe pump series has technical advantages such as sanitary, new structure, high flow rate and good precision.

Stage C
Principle of rotary lobe pump work - 4 | SeFluid
Stage D

A rotary lobe pump works on the principle of positive displacement, meaning it traps a specific volume of fluid and moves it from the suction side to the discharge side with each rotation of the lobes. Here's a step-by-step explanation of how a rotary lobe pump works:

Fluid enters the pump

The process begins when fluid enters the pump through the suction inlet. The lobes rotate, creating a vacuum in the space between the lobes and the casing.

Fluid trapping

As the lobes continue to rotate, the fluid is trapped in the spaces between the lobes and the casing. The shape of the lobes and the close tolerances between the lobes and the casing prevent the fluid from flowing back to the suction side.

Fluid transport

As the lobes rotate further, the trapped fluid is carried around the casing. The fluid is effectively transported from the suction side to the discharge side of the pump.

Discharge of fluid

As the lobes complete their rotation, the trapped fluid reaches the discharge outlet. At this point, the fluid is forced out of the pump and into the discharge piping or system.

Repeat the process

The rotation of the lobes continues, and the cycle repeats. With each rotation, a fixed volume of fluid is transferred from the suction side to the discharge side.

It's important to note that rotary lobe pumps generally have two or more lobes that rotate in opposite directions. This design helps maintain a balanced flow and reduces pulsation. The lobes are typically synchronized using gears or timing belts to ensure proper alignment and efficient pumping.

The pump's performance can be adjusted by varying the speed of the rotation, the clearance between the lobes and the casing, and the size and shape of the lobes. These factors influence the pump's capacity, pressure capabilities, and efficiency.
