Sigma Kneader: The Solution for Mixing and Kneading

Mixing is an essential process in various industries, including food, pharmaceuticals, chemicals, and cosmetics. The quality of the mixing process can significantly impact the final product’s quality, consistency, and texture. Therefore, it is crucial to use the right mixing equipment to achieve the desired results. One of the most efficient and versatile mixing solutions is the Sigma Blade Mixer.

The Sigma Blade Mixer‘s principle of operation is based on the kneading and shearing action of the blades. As the blades rotate, they create a shearing force that breaks down the materials’ particles, resulting in a homogeneous mixture. The kneading action of the blades also helps to blend the materials thoroughly, ensuring that all components are evenly distributed. The mixer’s unique design allows it to achieve a high level of mixing efficiency, reducing the mixing time and energy consumption.

There are two main types of Sigma Blade Mixers: the tangential blade mixer and the intermeshing blade mixer. The tangential blade mixer features two blades that rotate in opposite directions, with one blade tangential to the mixing chamber’s wall. This design allows the mixer to handle high-viscosity materials and achieve a high level of mixing efficiency. The intermeshing blade mixer, on the other hand, features two blades that intermesh with each other, creating a more intense kneading and shearing action. This design is ideal for mixing low-viscosity materials and achieving a more uniform mixture.

Principle of Sigma Kneader

The Sigma Kneader is based on the principle of kneading, which involves the mixing of two or more materials to form a homogeneous mixture. The machine consists of two blades that rotate in opposite directions, creating a shearing and kneading action. The blades are shaped like the Greek letter sigma, hence the name Sigma Kneader. The kneading action of the blades ensures that the materials are mixed thoroughly, resulting in a uniform mixture.

Types of Sigma Kneader

There are two types of Sigma Kneaders: the single sigma kneader and the double sigma kneader. The single sigma kneader has one blade that rotates in one direction, while the double sigma kneader has two blades that rotate in opposite directions. The double sigma kneader is more efficient than the single sigma kneader, as it provides a more thorough mixing and kneading action.

Application Scope of Sigma Kneader

The Sigma Kneader is a versatile machine that can be used in various industries. It is commonly used in the pharmaceutical industry for mixing and kneading drugs, ointments, and creams. The machine is also used in the cosmetic industry for mixing and kneading lotions, creams, and gels. In the food industry, the Sigma Kneader is used for mixing and kneading dough, chocolate, and other food products. The machine is also used in the chemical industry for mixing and kneading adhesives, resins, and polymers.

Advantages of Sigma Kneader

The Sigma Kneader has several advantages over other mixing and kneading machines. Firstly, it provides a more thorough mixing and kneading action, resulting in a uniform mixture. Secondly, it is a versatile machine that can be used for a wide range of materials, including high viscosity products. Thirdly, it is a low maintenance machine that requires minimal cleaning and upkeep. Lastly, it is a cost-effective machine that provides a high return on investment.

The three most common sealing methods for Sigma kneaders

Sigma kneading machine mainly adopts a vacuum dynamic sealing device. At present, the mainstream equipment adopts packing seal, mechanical seal, and magnetic fluid seal.

Mechanical seal: It has high-quality sealing, and leakage is almost non-existent. It has strong durability and generally has a long service life, but the requirements for processing, installation, maintenance, and maintenance are higher than those of general seals. This kind of mechanical seal equipment is especially suitable for conveying petroleum and chemical media and can be used for media with different viscosities, strong corrosion, and particles.

Packing seal: The Sigma kneader sealed in this way has the characteristics of simple structure, low price, and convenient maintenance, but this kind of seal occasionally has the problems of large leakage and large power loss. Therefore, the packing seal is used to convey general media, such as water; it is not suitable for petroleum and chemical media, especially in expensive, explosive, and toxic media.

Magnetic fluid seal: Compared with packing seal, it has the following advantages: long service life in oil and water medium, generally up to 1 to 2 years or more, and in chemical medium, it can usually reach more than half a year; reliable sealing in long-term During the cycle operation, the sealing state is very stable, and the leakage is very small. According to rough statistics, the leakage is generally only 1/100 of the packing seal; wide application range. The mechanical seal can be used for low temperature, high temperature, vacuum, high pressure, and different speeds. , and the sealing of various corrosive media and media containing abrasive particles.
