A vacuum emulsifying mixer or emulsifier machine is used to mix, disperse, homogenize, emulsify, and aspirate materials that are very thick. This machine has a heating and cooling system as well as a vacuum system. It is widely used to mix creams, lotions, ointments, liquid creams, etc.
Depending on production needs, this emulsifier machine can be semi-automatic or fully automatic. Now, what is the difference between them?
Semi-Automatic Vacuum Emulsifying Mixer
A semi-automatic emulsifier mixer needs both human and machine input to work. The materials are put into the pots by hand, and the machine is set to run. This machine does emulsifying work, and the finished product must be taken out of the tank by hand. Also, it has to be cleaned and sanitized by hand. This is because CIP and SIP are not built into the semi-automatic emulsifying mixer.
Water and oil containers, a vacuum system, a hydraulic lifting system, and a tilting mechanism are also included in a semi-automatic. It also features a heating and cooling system, a temperature control system, and an electric control panel. It operates the same way as the automated version, but human input is necessary for the emulsification process to be effective.
Automatic Vacuum Emulsifying Mixer
Because it has a high-speed shear head , a fully automatic emulsifier machine can move at a very high speed. It has a blade mixer for mixing ingredients that are very thick and a high-speed homogenizer that makes emulsification easier.
This automatic emulsifier mixer gets rid of dead corners by using scrapers to remove all the materials stuck on the surface of the mixing tank. A downward current is made to help mix the materials and move them along in a continuous process. High speed causes pressure to change from the bottom to the top of the homo-head. This causes breaking, mixing, and emulsification. The materials pour out of the homo-head’s top, and the blade mixer’s down-force brings them back. This happens when the force going up goes down.
Low viscosity materials may be easily emulsified with this kind of equipment. The raw ingredients are automatically sucked into the mixer using a vacuum function. Vacuuming, heating, and chilling may all be done in a single process. quickly as it is automated.
It is fully automated and controlled by a touch button, a timer, and a process recorder. Stainless steel is used to make parts that don’t touch the materials. Because it works in a vacuum, it automatically stops air from getting into the chamber where the mixer is. This machine can also be set up with CIP, which helps the mixer regularly clean itself automatically.
Other Vacuum Emulsifying Mixer Efficiency Factors
How do vacuum emulsifying mixers vary in efficiency?
The effectiveness of a vacuum emulsifying mixer depends on a number of factors. They can be:
◎ Material density, dispersion, wettability, stickiness, and other physical qualities all impact the vacuum mixer’s efficiency.
◎ The natural properties of the ingredients that need to be emulsified are also important. Rough things tend to stick together, which makes a perfect emulsion.
◎ For ingredients to mix well, pieces should be about the same size. Particle size variation produces unwanted effects.
◎ The shape of the ingredients is another thing that affects how well this machine works. Materials that have round shapes tend to mix well with each other. Material particles with odd shapes don’t mix well.
◎ Electrostatically charged particles that tend to stick to each other tend to move away from other materials. This makes it harder for the oil and water to mix together.
◎ The choice of vacuum emulsifying mixer is the last and most crucial factor. Choose a machine that works well, doesn’t cost too much, and works consistently to ensure excellent results.
What is the operating temperature range of the vacuum emulsifying mixer?
The temperature at which work can be done can be between 50 and 60 degrees Celsius . When the valves are closed, you press the power button to start preheating the water and oil pots. The temperature needs to go up to 50 degrees Celsius, and then it needs to be stirred to keep going up.
You not only heat the materials to the right temperature, but you also stir them. This is done to ensure that the ingredients in creams are heated to the same temperature as the mixer. The emulsifying pot is heated to the same temperature (around 60 degrees Celsius) as the water and oil pot.
But first, the heating valve must be turned on while the input and outlet valves are shut. A vacuum emulsifying mixer’s operating temperature may sometimes reach 80 degrees Celsius. However, adding a cooling system to the emulsifying pump and bearing plate may work out nice. With a single-stage emulsion pump, this works well.
If you have a three-stage emulsion pump, a high-temperature O-ring can also help. This can work well at temperatures as high as 220 degrees Celsius. For emulsification to go on all the time, you should use a machine with a cooling system. This will help the machine handle the high temperatures that will rise as it works.
