What Is a Chemical Vacuum Double Planetary Mixer and How Does It Work

Especially in chemistry related industries where the processing of chemical and material involves mixing activities, it must be efficient in its every mixing task. The Chemical Vacuum Double Planetary Mixer by Shanghai Rumi Electromechanical Technology Co., Ltd. can be stated as one of the most efficient machines for this purpose. This elegant piece of equipment is used in many industries ranging from the pharmaceuticals to the plastics industry. But what does this mixer in fact mean and how does it operate? I believe it is now time to get into more details on the vacuum double planetary mixer in terms of its structure and use, functions and advantages.

Understanding the Structure and Application of the Vacuum Double Planetary Mixer

The Vacuum Double Planetary Mixer by Shanghai Rumi Electromechanical Technology Co., Ltd. is mainly a sophisticated mixing equipment which is developed to mix the high viscosity and high density of the material. The general design of this mixer is characterized by a complex and highly effective system that enables excellent mixing functions. What makes this device to stand out from the rest is the aspect of vacuum technology and the double planetary mixing process.

Structure

It is a cylindrical, or occasionally conical, mixing vessel that may be jacketed to accommodate thermal conditioning. Inside this vessel, two planetary gears turn both on their own bearings and also on the common axis. This dual operation mimics a planet’s orbiting and that is why it is call the planetary mixer. It is the blades on these gears that help to mix it thoroughly.

In the case of the mixer, the vacuum aspect is specifically large. In order to manufacture the entire compound under vacuum conditions the whole mixing process is often performed under a vacuum. The reduction of voids within the material being blended results in better quality of the finished product. Moreover, there are also efficiencies such as that under vacuum conditions, degassing of the materials is possible, oxidation is decreased, and the chemical reactions between the components being mixed are improved.

Applications

Due to its wide application features, Vacuum Double Planetary Mixer can be applied in various fields. In the pharmaceutical field, it is applied in combination of the active pharmaceutical ingredients (APIs) together with the excipients in order to achieve homogeneity. This means that there is less variation in dosage forms such as tablet and capsules.

In the chemical industry, the mixer handles highly elastically thixotropic products such as adhesives and sealants or lubricants. It is also involved in the manufacture of various types of plastics and composites especially in applications where homogenously distributed addendum and /or fillers are essential.

This mixer is also used by cosmetics manufacturers to apply creams, lotions and gels to form products without containing visible air bubbles.

The Function of the Double Planetary Mixer

The primary application of the Double Planetary Mixer is to achieve uniform batch, isotonic and non-isotonic blending of precursor materials, binder systems, and additives with different viscosity and specific gravity. Here's a closer look at how this is achieved:

Dual Planetary Action

The two type of movements refer to the mobility of the moving blades in a planetary system; whereby the blades move in circular motion around the fixed axial spindle, they also can move in circular motion on their own spindles. This motion makes it possible for the enlarged mass of the material to be continuously rotated and blended. It assists disperse the agglomerates and makes sure that they are distributed all through the system.

Vacuum Environment

Looking at it from this perspective, the operating of the mixer under vacuum has several advantages. First of all, it does not allow air to be entrained – this is especially critical in high viscosity mixes. Any kind of void or gap between the two parts will cause problems to the final product, for instance they can produce voids or even uneven texture. Due to the exclusion of air, the mixer results to the development of a denser and uniform quality.

The vacuum also helps in degassing since volatile gases and water are removed as they are required especially for some reactions and also product shelf life. For instance in the pharmaceutical industry this enables the company to prevent wet sensitive products such as a compound to degrade during the mixing process.

Temperature Control

Some Vacuum Double Planetary Mixers are also fitted with a temperature control. The mixing vessel may be jacketed so that heating or cooling fluids may be circulated through the jacketing. This feature is very important for processes, where temperature control is important for getting the right blend characteristic of the products.

Homogeneous Mixing

Because of a rigid construction and operation of the Double Planetary Mixer, a high homogeneity is provided. Regardless which type of bulk is being handled, powders, pastes or semi solids, the mixer helps make sure that such batches are well mixed. Such consistency is important for the quality and performance of the products, involved in the food chain.
