What is a Double Planetary Mixer? When working with dough, icing, or any other viscous material, a planetary mixer is an indispensable tool. You may use them to mince or grind all sorts of foods, including veggies, fruits, and even meat. Pasta makers, grinders, and shredders are all available as attachments for certain versions of planetary mixers.
Double Planetary Mixer
A Double Planetary Mixer combines required mixing with great efficiency and full functionality. A frame, hydraulic lifting system, geared motor, agitator, planetary carrier, wall scraper, and barrel make up the double planetary mixer.
Two blades in this mixer spin around the mixing vessel on a shared axis, while also rotating on their individual axes. Striking away at the vessel’s outside, the blades move relentlessly, transferring material to the inside. With only one full rotation, the blades will have gone around the whole vessel; three full rotations will have mixed the majority of components; and 36 full rotations will have touched almost every part of the batch.
- Effective kneading, dissolving, mixing, and reaction capabilities.
- There are four main types of agitators: paddle, twist, claw, and frame.
Structure
The double planetary mixer has an intricate structure. It completely incorporates the benefits of planetary mixers with strong dispersers by combining their respective properties.
In contrast to the planetary mixer’s slower impeller rotation and revolution, this one combines a series of fast dispersing shafts and a dispersing disc to achieve both high-speed dispersion and low-speed stirring. While running, it is possible to modify the frequency to alter its speed and achieve simultaneous self-rotation and revolution.
Working Principle
The two stirring shafts inside the mixer’s housing will begin to spin once the double planetary mixer is turned on since the planetary frame will spin in tandem with it. It will knead and shear the materials vigorously as it spins around the barrel’s axis at high speeds. With the goal of complete dispersion and mixing in mind. Also, on the planetary frame, you’ll find a row of wall-scraping knives. These knives spin in tandem with the planetary frame and cling to the cylinder wall, scraping relentlessly to remove any debris that has settled there.
Spiral Mixer VS Planetary Mixer? The process of mixing ingredients is where planetary mixers and spiral mixers differ.
Application
The following industries may benefit from the use of a double planetary mixer:
Food
The versatility of this mixer makes it a great investment for any food preparation, whether you’re making sauces, bread, batter, or many other ingredients. In the food business, where speed and accuracy are most important, a mixer is an indispensable instrument because of its great efficiency and reliable output.
Cosmetics
A double planetary mixer finds further application in the cosmetics sector to blend various cosmetic items such as lotions, creams, and more. In the very precise and quality-conscious cosmetics sector, the mixer is an essential equipment due to its versatility and capacity to provide consistent results with a variety of components.
Pharmaceutical
The pharmaceutical sector is another user of double planetary mixers, which are useful for combining various lotions, ointments, and powders. If you work in the pharmaceutical sector, where precision and sanitation are crucial, you need a mixer that can handle a wide variety of substances and consistently provide results.
Chemical
To combine various compounds, the chemical industry also makes use of double planetary mixers. Because of its versatility and reliability, the mixer is a must-have in the chemical sector, where precision and safety are paramount.
Emulsions, coatings, polymer materials, pastes for batteries, and more.
Features
Sufficient Capacity
Making batteries calls for additional pole parts and demands more consistent batteries. Accordingly, the solution must have a particular consistency. Because the mixing procedure involves stirring, timing, and feeding in a certain order, the slurry in every pot will vary. The consistency could vary. So, there’s a minimum capacity for the mixer. Currently, the capacity of the big mixer may be up to 2000 liters. Materials’ mixing abilities and effects must be taken into account when the capacity is sufficiently big.
Reliable Technique for Vacuum Sealing
There are three key reasons why the mixer needs a reliable vacuum sealing system:
- Temperatures will grow during the stirring operation as a result of rising heat generation from the materials and the agitator’s frequent collisions and frictions. As the temperature rises, some solvents, such as PVDF and NMP, release a strong, unpleasant odor. When inhaled, organic gasses cause severe health problems for humans.
- Poor closed-system handling of the powder during the dry powder premixing step may lead to dust dispersion. Which in turn can hurt workers, decrease product quality, and impact the surrounding environment.
- After mixing the powder with the solvent, there should be many bubbles within the slurry because of the vast spaces within the powder. Degassing the slurry is an important step before coating the pole. Failure to do so will result in the coating bubbles popping, surface density changes, and possible foil exposure—all of which would have a devastating effect on the battery’s performance.
Compatible Agitator Blade Construction and Speed Design
An important factor in slurry preparation is the mixer’s mechanical design and the form of its blades, along with the mixer’s stirring range and power. There should be no dead angle in the stirring vessel and the agitator’s stirring range should be considerable enough. Today, bigger mixers use planetary agitators with two or even three shafts to mix the active ingredient thoroughly into the slurry without any particles or lumps.
The second point is that the agitator’s form design completely affects the material’s mixing, dispersion, fluidity, distributing particle size, etc. Paddle, butterfly, anchor, twist, claw, frame, and more typical forms are already available. The fast dispersion machinery is the most important piece of equipment to have on hand since dispersing some materials necessitates the use of rapid shear force.
Thirdly, the machine must have a stirring speed sufficient to achieve the targets, which are ultrafine powder dispersion and high molecular weight.
There is machinery that includes features like scraper layouts and container rotations to further enhance the effectiveness of stirring and the level of material mixing, in addition to the primary blades and stirring shaft.
Mixer Material Resists Corrosion, and Wear, and has Steady Physical and Chemical Qualities
The positive electrode material’s high alkalinity and NMP’s high corrosion resistance aren’t going to stop the mixer from needing exceptional resistance to corrosion. Because the agitator will be constantly swirling the powder during the operation, it must be durable and resistant to wear.
Mixer’s Safeties
To ensure the operator’s safety, the mixer’s design must adhere to acceptable safety standards. These can be explosion-proof, have an emergency stop mechanism, be stable, etc.
Advantages
Mixing Process
Because of its distinctive mixing action—two planetary blades that revolve around a central axis—the double planetary mixer gets its name. By simultaneously moving the contents in two different directions, the blades of this mixer provide a mixing process that is both efficient and effective. As a consequence, the mixing time decreases and the mixture is homogeneous with very little air trap.
Viscosity-Based Mixing
The mixer machine‘s capacity to process materials with a high viscosity is a major strength. The powerful shearing force from the mixing movement may dissolve and disseminate the most resistant substances. Uses requiring a high amount of shear to generate a homogenous mixture, such as sealants, pastes, and adhesives are ideal for this mixer.
Multi-Blade Setups
There is a wide range of blade configurations available for double planetary mixers. This allows them to be customized to meet specific mixing needs. Three kinds of blades—the ordinary paddle, the helical, and the scraper—are the most popular. While helical blades are better at dispersing and mixing at high shear, paddle blades are good for general blending and mixing. Scraping the inside of the mixing vessel with the scraper blade will ensure that all ingredients are well combined.
Pressure and Vacuum Abilities
The ability to regulate the mixing conditions and enhance product quality is a common feature of twin planetary mixers, which includes vacuum and pressure abilities. Pressure mixing increases stability and density, whereas vacuum mixing decreases oxidation risk and eliminates air bubbles. Pharmaceutical and cosmetic manufacturers, which place a premium on product uniformity and purity, find these characteristics helpful.
Optional Customizations
A selection of dimensions, features, and capacity choices makes double planetary mixers highly adaptable to particular demands. You may equip the mixer with heating and cooling jackets, variable speed motors, and automated controls to make it even more efficient and effective. Companies making these products have a lot of leeway in terms of vessel size and shape, blade design, and material selection.
Easy to Maintain
There is less downtime and higher productivity with the double planetary mixer because of how easy it is to clean and maintain thanks to its simple and accessible design. Because you can remove the mixing bowl and the blades, cleaning is a snap. To guarantee safe operation and prevent accidents, the mixer contains safety features such as interlocks and emergency stop buttons.
Economical
This mixer is a great option for manufacturers looking for an affordable solution, even though it has significant capabilities and features. The mixing process is efficient, which means fewer machines and manpower are necessary. The design is simple to clean, which means less repairs and maintenance expenditures. In addition to enhancing the mixer’s value and ROI, its adaptability gives manufacturers a leg up when it comes to finding uses for it.
