How to Use a Vacuum Emulsifier to Make Creams and Ointments

Vacuum emulsifier is a piece of equipment that helps refine and disperse creams and ointments. It also makes sure there are no dead or hard corners in the finished product.

It is used in many industries that require a lot of mixing procedures like making gels, preparations, ointments, and product suspensions. It is mainly composed of water tank, oil tank, emulsify pot, lifting system, vacuum pump and electric control system while PLC is optional.

Homogenization

A vacuum homogenizer mixer is an ideal machine for emulsifying, dispersing, and mixing immiscible materials in pharmaceutical and cosmetics industries. The machine’s high shear and high speed combine to form a uniform phase. It can also be used to make creams, ointments, and product suspensions. Its operating platform, emulsifying pot, and lifting mechanism are all designed to provide a closed system for effective homogenization.

The homogenization process is performed using the powerful kinetic energy of a rotor and stator, which creates strong hydraulic shears within the gap between them. These shears can be used to squeeze, disperse, and impact the materials. The homogenizer mixer also has a cooling circulation and vacuum institutions. The mixing process is regulated by an electric control system.

Compared to SDS, the LEC molecules have larger hydrophilic heads and tails. This makes the emulsifier more steric hindered, and reduces the degradation of curcumin in the oil phase [24]. Moreover, LEC has better lipid solubility, and can protect the emulsion by forming three-dimensional supramolecular networks.

Vacuum Homogenizer mixer is a high-end professional equipment that is widely used in various industries. It can produce viscous emulsion, dispersion and suspension in daily Vacuum emulsifier chemical care products, biopharmaceutical industry, food industry, printing and dyeing auxiliaries, pulp and paper, nanometer materials, pesticide, fertilizer, plastic & rubber, and electrics & electronics.

Dispersion

If you make ointments and other highly viscous products, you need to mix them correctly in order to get the best results. The wrong mixture or mixing speed can cause lumping, clogging and other problems. The solution is to use a high shear mixer with the right temperature and mixing time to produce an evenly mixed product. This will also prevent air incorporation into the product during stirring.

The vacuum emulsifier is designed to shear, disperse and impact the materials quickly and evenly. It uses the strong shear forces to push the materials inside the gap between rotor and stator and creates a powerful turbulence. These shear forces also cause the material to undergo strong squeezing, impact, centrifugal extrusion and crushing and generate liquid layer friction to make it fly through the gap.

The vacuum emulsifier is an excellent choice for making creams and ointments that contain many solids. It can also help you create suspensions and other products that need to be dispersed. It can even help you make oil with a lot of solids into an emulsion. This machine is easy to operate and can handle a large amount of powder. It also has a dust-free system and auto feeding. This makes it a good option for laboratories. Its small size and simple operation allow you to work in a limited space without worrying about contamination.

Stability

There are several factors that can influence the stability of a dispersion system. In addition to the viscosity of the aqueous phase and the droplet size, the density difference between the inner and outer phases is also important. Detecting this denser layer and taking steps to stabilize it can prevent demulsification. One of the most common methods of stabilizing an emulsion is injecting chemical treatments into the aqueous phase. However, these chemicals must be carefully chosen to avoid destabilizing the emulsion.

Stabilization can be achieved by surfactants, which are able to reduce the interfacial tension between the oil and water phases. They Automation equipment supplier can also adsorb onto the surface of the droplets to form a protective film, which prevents the dispersed droplets from aggregating or coalescing. Other effective methods for stabilizing emulsions include incorporating solid particles into the dispersion medium. These particles can be either oil-wet or water-wet and should be of sufficient concentration.

Another way to increase the stability of an emulsion is by adding polyelectrolytes. These molecules have a charge and are able to decrease the electrostatic repulsion between dispersed drops. A high concentration of polyelectrolytes can also prevent the formation of a coalescing layer, which is induced by steric effects. These polyelectrolytes can also be used to increase the viscosity of the aqueous dispersion phase and reduce the concentration of ions in the bulk phase.

Efficiency

The efficiency of vacuum emulsifying mixer is influenced by several factors such as the type of mixing and temperature. The mixing time and speed also affect the final result of a homogenous mix. High-speed emulsification with proper heating can avoid the formation of lumps, clogging and other issues that can cause a decrease in mixing efficiency.

Vacuum emulsifiers are used to emulsify products with different viscosities in the cosmetic, food and pharmaceutical industries. They are also widely used in the oil industry to improve water-flooding efficiency. Emulsified crude oil can increase the recovery for a low water cut, whereas spontaneous emulsion flooding and micro-emulsion floods are essential technologies for high water cuts.

In the vacuum emulsifying machine, liquids are mixed by a blades-mixer and pumped into an emulsifying pot through a vacuum pump. The rotor has scrapers to scrape the surface of the emulsifying pot to prevent dead corners. The scraping action of the rotor creates a downward current that mixes and pushes the materials going through the homogenizer continuously.

Vacuum emulsifiers also have a center edge stirrer to disperse particles and reduce the size of drops. This ensures a uniform distribution of the materials in the emulsion and prevents clogging of the vacuum pump. They are available with a variety of features, including high-speed shearing and blending power. They are ideal for emulsifying heavy products, such as oils and fats.
