Overview of Sanitary Mixers and Blenders

Sanitary mixers are machines that blend, mix, homogenize, or emulsify various product ingredients in a processing plant. They are used extensively in hygienic industries, including food & beverage processing, pharmaceutical manufacturing, and the home and personal care industries.

Indeed, for these types of businesses, it may accurately be said that mixing and blending is one of the key value-added steps in the manufacturing process. Unlike mixers found in the home, sanitary mixers are large and complex pieces of machinery.

To maintain hygienic standards, the majority of hygienic mixing tasks are performed in closed containers with limited air supplies and under controlled temperatures.

In the hygienic processing industries, mixers prepare a wide variety of products, including:

  • Toothpaste
  • Food coloring
  • Syrups
  • Beverages such as milk and soft drinks
  • Medical ointments
  • Lotions
  • Creams
  • Vitamins
  • Shampoos
  • Hair dyes

In food processing factories, mixers add stabilizing preservatives to make food products transportable and suitable for consumption. Operators may use them to combine different types of solids (as is the case with powder mixers) and liquids of various types (both viscous and non-viscous). Mixers may also be used in specialized applications to mix a liquid into a solid or a gas.

Specific types of mixers are designed and engineered to handle each of these varying applications, as will be shown in the subsequent sections of this guide.
