What are Differences among Homogenizers, Stirrers and Emulsifiers?

Homogenizers, stirrers and emulsifiers are widely used in bio-pharmaceutical field, food industry, daily care products and other fine chemicals. Actually, they vary from each other, mainly reflecting in principles, applications, and their pros and cons.

  • They have different principles.

A homogenizer works by the precise coordination of a rotor and a stator. The rotor rotates stably at a high speed to form high-frequency and intense circumferential tangent velocity and angular velocity to achieve homogenization. A stirrer works by the high-speed rotation of a blade at the bottom, which can stirrer and break materials repeatedly under the action of current. An emulsifier works by the high-speed rotation of a homogenizing head connecting to the motor, which can shear, scatter and impact materials. In this way, materials will become more delicate.

  • They are used in various fields.

A homogenizer is generally used for tissue dispersion in the field of biotechnology, sample preparation in the field of medicine, and enzyme processing in the food industry. A stirrer can be commonly used in chemical, food, pharmaceutical, cosmetics, environmental protection and other fields. Some of them can be used to mix, homogenize, suspend, and recirculate large volumes and high-viscosity substances. And even some of them can keep liquids being stirred automatically as they are heated for a faster reaction. An emulsifier is widely used in adhesive, paint coating, cosmetics, food, medicine, plastic resin, printing and dyeing, ink, asphalt and other industries.

  • All of them have pros and cons.

A homogenizer can mix best, but it has a big power consumption, low output. A stirrer is the most traditional stirring method with wide applications, which is convenient to use. But it can only mix materials simply without shear and fining effects. An emulsifier has a great mixing effect. A suitable emulsification head can be applied in a great variety of conditions. But it has a relatively low output and is not suitable for hard granular materials and high viscosity materials.
