Planetary Mixer – Advantages in Pharmaceutical, Biotech and Chemical Industry

A planetary mixer has several applications and mainly used for the purpose of intensive mixing. The agitation pattern of this mixing assembly is planetary in nature and hence the name. This is an effective method of mixing since there is a rotation of the planetary blades on their own axis in addition to the rotation around the center of a mixing bowl.

This special design allows a shifting of the mass in a uniform method, hence allowing for an effective mixing of medium to high viscous liquid. This article goes on to explain all main features of a planetary mixer and advantages of using it.

 Planetary Mixer – Main features

There are many factors that can vary depending on the type of planetary mixer you have opted for. Different models have different specifications with varying gross capacity, working capacity, lifting motor, main motor, RPM beater, space requirement.

Few main elements of a planetary-mixer are:

  • Bowl to place the ingredients.
  • A mixing element of some kind like hook, flat beater, etc.
  • Motor to enable the whisks moments.
  • An operator box to control mixing process, timing, speed and more.
Additionally, there are also several accessories like a dough hook which comes handy to knead bread dough, cakes, pizza, cookies, etc. A mixing paddle helps with mixing cream, masses of the Genoese, etc. A whisk accessory allows to beat egg white portion, also mayonnaise and soft cream, etc.

Listed here are few main features of a planetary-mixer:

  • Single or double Planetary Blades.
  • Floating scraper blade which adjusts itself to bowl contour.
  • Mounting simplicity with a single base structure.
  • Manually and hydraulically operated lift using an air or an oil electric pump.
  • Durable special steel planetary gears known for long life are also heat treated and hardened.
  • Multiple blade options like stirrup, vertical, or a combination.
  • It has a high mixing efficiency since speed of the blades can be controlled.
  • It is very easy to handle, clean and maintain.
  • It ensures uniform consistency and a homogeneous mixing.
  • Consists of a control panel to limit the traverse motion as well as other elements.
Benefits of using a Planetary Mixer

This is mainly used for blending a mixture of thick ingredients that is hard to blend. It is usually not used to blend liquid substances. This mixer helps reduce manual labor and the big effort involved in mixing a major portion of the substances as per industry requirements.

Here are the advantages of using a planetary-mixer:

  • A planetary-mixer can handle all challenging materials to provide an optimum homogenization mixture.
  • A major advantage being it has low wear and tear with very little maintenance required.
  • Wastage of material and other substances is kept to the minimum.
  • The mixing stars rotation is on different axis, thus making it more efficient.
  • All material is completely recirculated as well.
Common Applications

Type of blades on a mixer is variable. It can also be of different shape and size and is mounted on a unique axis. This has many applications in a bakery due to few interchangeable utensils and the several accessories that are easily available.

It has many other applications of which few are listed here:

  • General Chemical Industries
  • Adhesive and Sealant
  • Caulking and Wax Compound
  • Dental Fillers, Powder Coating, Blending powders
  • Battery Pastes, Gel Products
  • Food products, Bakeries
  • Pharmaceuticals, Cosmetics products, creams, lotion etc.,
  • Biotech industries, Emulsions, Explosive
  • Agricultural pesticide products
  • High-Viscosity product
  • Colors, Resins
