The Benefits of a Vacuum Mixer
Vacuum mixers can help improve the quality of your materials and make your manufacturing process more efficient. They can also reduce oxidation and contamination. They can also shorten processing time.
Our Vac-U-Mixers are great for mixing phosphate investments, alginates and die materials. They can be used with our Power Mixer Plus or Combination Unit.
Mixer blades
Mixing under a vacuum helps to avoid incorporating air into the mix, which can cause bubbles. It also prevents the mixing of air-sensitive compounds. Many companies offer vacuum mixers for scientific, food service, and medical use. They can come with various mixing attachments to suit different applications. These can include a squeegee blade that wipes the sides of the container continuously. They can also be equipped with a degassing function to vent off excess gas that can cause oxidation.
The squeegee blade increases the axial flow of the mixture during mixing and improves heat transfer. It can also help to reduce the number of defects in the vacuum mixer finished product, and it makes it easy to clean between batches. The squeegee blade is an optional feature of many vacuum mixer models.
The HV Blade enhances the capability of a double planetary mixer for high-viscosity materials. The angled surfaces on the vertical bars and the lower crossbar of traditional planetary blades promote effective axial flow, but these blades are not suitable for heavy materials. The HV Blades eliminate these problems and are ideal for highly filled adhesives and sealants. They have a flat leading edge and a helix-shaped trailing edge that prevents heavy materials from climbing up the shafts. The HV blades are suitable for mixing a wide variety of materials, including butyl and liquid-butyl sealants, bulk molding compounds, and lithium-ion batteries.
Vacuum chambers
Vacuum chambers are an important part of a vacuum mixer. They help prevent air bubbles from forming in the mix and help the material expand evenly. They can be made of a variety of materials, including metals and glass. The best method for creating a vacuum chamber is welding, which requires highly skilled welders. There are a number of welding techniques that can be used, including butt, lap, corner, and tee welds.
A vacuum mixer is useful for mixing and degassing high-viscosity products, such as pharmaceutical drugs, cosmetics, and polyurethanes. It can also be used to chop foods in a vacuum state, which reduces food waste and keeps the product fresh for longer. Its rotation and revolution mixing function eliminates the formation of air bubbles, allowing for faster processing than traditional hand-mixing methods.
The mixer can be fitted with a vacuum pump and a selection valve. The selector valve connects the dram with the vacuum throat and the pump creates a vacuum pressure below 29 inches of mercury. This allows the material to expand up to 4-5 times its original volume, which is important for the quality of the final product.
Vacuum chambers are also essential for testing and manufacturing products that need to endure a wide range of temperatures and conditions. For example, the aerospace industry uses large vacuum chambers to test components and parts before they go into space. They can be constructed from a variety of materials, but they have to be strong enough to withstand drastic changes in pressure.
Vacuum pumps
In order for a vacuum mixer to operate, it needs a power source and a pump. It is important to understand the different types of pumps available and how they work in order to choose the right one for your application. For example, liquid ring pumps have an off-center impeller with vanes that bend towards rotation and form a moving cylindrical ring of liquid from centrifugal acceleration. As the rings move, the volume of each space changes allowing the liquid to seal off and draw in gases. Scroll pumps, on the other hand, provide hydrocarbon-free vacuum by compressing gases using two tip-sealed spirals.
A wet vacuum pump requires a special lubrication system to protect it from heat and contaminants. This system consists of a pump and an auxiliary lubrication system that uses oil for sealing and cooling. These systems have the advantage mixer manufacturer of being able to handle liquids and dusts that would otherwise damage other vacuum pumps. However, this type of pump is usually more expensive and requires an additional contaminant-rejection system downstream.
Vacuum mixers are used to disperse and bind powdered active pharmaceutical ingredients for manufacturing solid dosage forms such as tablets, effervescent pills, oral capsules, or suppositories. They also help to reduce drying times by lowering the overall system pressure. The agitation system in the vacuum mixer is typically made of counter-rotating anchor or blade and high shear homogenizing turbine agitators to ensure that all of the powdered ingredients are thoroughly dispersed.
Safety
Mixing, blending, and drying under vacuum reduces oxidation and improves the overall quality of your product. This is because mixing under vacuum removes oxygen from the mixture and keeps it in its natural state, reducing degradation and increasing shelf life. Moreover, vacuum also eliminates airborne pathogens and helps keep a uniform batch size.
The emulsifying pot of vacuum mixer is equipped with a mirror, which allows you to observe the emulsion inside it and monitor the process. This feature ensures a safe and efficient operation. It also makes the homogenization of high viscous materials faster and easier. Besides, it saves raw materials and reduces the cost of production.
A vacuum emulsifying mixer is more energy-efficient than conventional mixers. It consumes less electricity and gas to run, so you can save money on your utility bills. Furthermore, it has a built-in safety valve that prevents the opening of the pot lid when there is a vacuum present inside the container.
It is important to understand the different types of mixers and how they work. This will help you choose the right equipment for your application. In addition, a good mixer should be easy to maintain and safe to use. Make sure to follow the manufacturer’s instructions for maintenance and cleaning. Also, be sure to lock out all power supplies before performing any maintenance or repairs on the equipment.
