When your goal is to create a uniform combination of two or more materials that don't mix together easily, you have several options for which method of mixing you use. Two of the most effective options are high shear mixing and homogenizing.
High shear mixers and dispersers are frequently used in a variety of industries, including the chemical, cosmetic, pharmaceutical, and food industries. Here at Canaan, we offer varying degrees of high shear mixers, which are a popular choice for businesses requiring liquid mixers or laboratory mixers and employ a “flow-driven” process to achieve results. Made up of a stationary stator and an inside rotor, or impeller, that turns at high speeds, high shear mixers are often used for emulsification, homogenization, particle size reduction, and dispersion. Mixing speed required to achieve a uniform mix will depend on various properties of the ingredients, such as their viscosity.
By contrast, high pressure homogenization breaks down particles and creates a uniform substance by forcing substances through a narrow space. This method uses force in combination with high levels of pressure to create a consistent and uniform mix. Typically, the high pressure homogenization process is best suited for both micro and nano-emulsions.
By studying the working principle of the two, we can see that the high shear homogenizer is mainly due to the high shear effect of the relative high speed motion between the stator and rotor, accompanied by strong cavitation the material particles were dispersed, refined and homogenized; and high-pressure homogenizer is mainly due to high-pressure fluid to produce a strong, full hole effect and turbulence in the fluid dispersed phase particles to achieve homogeneous purpose. It is easy to understand that the high pressure homogenizer is suitable for the treatment of soft and semi-soft granular materials due to the strong cavitation. It is found that the most effective force field for the pulverization of the fiber is shear force and grinding force, the impact force at room temperature is incapable for the fiber, and the high shear mixer can produces a strong shear and grinding effect on the material, so the high shear homogenizer is more suitable for the treatment of more fiber or high viscosity, hard particles material.
|High Shear Mixer
|High Pressure Homogenizer
|Raw material requirements
|Powder, lumps or fruit can be directly input
|The material must first be melted and mixed into a fluid to be homogenized
|No replacement parts within two years, no wearing parts
|Homogeneous valves and seals need to be replaced frequently for two or three months, with greater maintenance effort, especially under high pressure
|Flexible, simple, no need special operation
|Need special operation and adjustment
|Power consumption is 1/3 for the high pressure homogenizer
|High power consumption, waste of energy
|Wide range of applications
|Not suitable for high viscosity materials
|Homogeneous fineness up to 1μm below, good stability
|Homogeneous fineness small, good stability. In some industries, however, the results are poor
|Mixing, sterilizing, homogenizing complete at the same time
|Can only be used separately

Explore our range of high shear mixing equipment, including state-of-the-art blades like our F – blade, which is interchangeable with all other manufacturer's standard high shear blades and in fact, will last much longer and produce more sheer and pumping action. Or, take a look at our D – blade, also known as the “Ring” blade, a patented innovation that handles the toughest pigment agglomerates, rapidly dissolves resins, gums, and similar materials. Also be sure to consider our high shear mixers like the rotor stator which utilizes a rotor and a stationary stator that typically operates at very high speeds, creating a vortex circulating the product through the gap between the rotor and stator, resulting in a very homogeneous dispersion.
