2.What is the working principle of vacuum emulsifying mixers?

The working principle of vacuum emulsifying mixer is as follow:

The working principle of a vacuum homogenizer is almost similar to a high-shear emulsifying mixer.

• Making of a stable, emulsifying mixture followed by series of steps such as cutting, strong dispersing, emulsifying, and homogenizing with a help of rotor and stator.  A precise and accurate technology of vacuum emulsifying mixer is accompanied by strong coordination between rotor and stator.
• Firstly, a vacuum vessel creates an air-free environment where no oxidation takes place that ensures a high-quality mixing procedure to meet manufacturing requirements.The transferring of ingredients from the oil and water phase is allowed to the main working chamber.
• A motor facilitates strong speed rotation that ultimately results in the formation of a vacuum between rotor and stator.
• Mixing ingredients are introduced from the upper and lower part of the rotor and stator. A rotor is directly connected to a homogenizing motor with flanges. The average speed of the rotor is estimated as 3000rpm that generates a powerful suction force.
• All material is mixed by heating and continuous stirring side by side. With the help of attached Teflon blades. Adhesive ingredients are scraped off from the wall of emulsifying tank and flares upward to avoid further sticking and burning.

High Shearing Emulsification process of Vacuum Emulsifying Mixer

• By the action of several forces from multiple directions leads to generate strong turbulence that triggers the crushing, dispersing, centrifugation, and high shearing between rotor and stator.
• The cutting of material in the shearing seam takes place that quickly breaks the mixing particles into 200nm-2um in an emulsifying pot.
• In a vacuum state, air bubbles are produced during the stirring process which is removed at the time of the vacuum homogenizer mixer.A piece of auxiliary equipment, such as a water ring vacuum pump which pulls out the air bubbles and helps in generating strong mixing and homogenizing process.
• Because of strong forces by impeller and wall scraper, the mixing ingredients moves to top from bottom and this process repeatedly occurs. When the mixing has completed the heat from the jacket is rapidly transfer to inside the wall.
• The auxiliary equipment is connected for all-around targets. Such as an oil hydraulic pump is employed to boost the main body of the mixer. The purpose of safety equipment ensures the mixing of the product would not initiate till the cover is lifted.

There is a certain kind of fluid that requires some additional effort to get a uniform mix. For instance, mixing of water and oil phase.

The mixing of oil and water phase is a primary and mandatory method involved in the manufacturing of creams and ointments. Thus, their mixing requires a high shearing homogenization which is achieved by a vacuum emulsifying mixer efficiently.

When you combine these two phases (oil & water), the viscosity and texture of the sample are the targeted factors of the mixing game. So, always opt for those mixers that can efficiently handle these factors.

3.Lesser Waste Production

Using a vacuum emulsifying mixer has a better reduction in the wastage of materials. The presence of a scraper agitator has net-centrifugal effects throughout the operation and making perfect scraping around the wall of the emulsifying tank that collectively solves the complications of the sticky material around the pot with no adhesive particles so fewer chances of product deterioration.

Furthermore, the concentration of raw material wastage during each production process is now controlled than before. This is very commonly observed that at the end of the production cycle you get a large cost due to wastage of raw material, so vacuum emulsifying mixer has intricately surmounted this problem ultimately saves you extra cost.

4.High Production Capacity

If you have understood the above-mentioned benefits, you will get an idea that how the following factors of vacuum emulsifying mixers are directly proportional to an increase in the production capacity of the manufacturing unit.

In simpler words, timesaving, and reduction of wastage can increase your productivity. So, this is improving the production capacity. Similarly, here you are not requiring spending more time and investment of large costs on arranging raw materials. An enhanced turnaround and excellent production volume will give you more market to sell your products. An accelerated rate of production and high- quality directly benefits the consumer as well as the manufacturer.

8.How to troubleshoot the problems associated with vacuum emulsifying mixers?

A vacuum emulsifying mixer is a multi-functional device that can warm and cool the ingredients as well as mix and emulsify them.

But this process, sometimes an emulsified tank heats abnormally that transfers the unnecessary heat to mixing ingredients which greatly influences the production and processing of ingredients.

This problem occurs due to an increase in the absorption rate of heat in stainless steel. The reaction of the steel kettle is much greater than the heat supply that ultimately increases the temperature inside. For this purpose do not disassemble the parts of the machine by yourself to avoid unwanted damage to a mixer, rather contact the manufacturer to carry the maintenance.

Moreover, sometimes, machines generate heat due to high control on reducing the pressure and overflow valve. For this, you need to assess whether the vacuum valve is open or refueled properly. Also, you need to check if a sealing ring is leaked, a water tank is filled with water and the potation path is correct or not.

• Sometimes, the heating temperature of the vacuum emulsifying mixer cannot go up. For this, you need to examine certain points.
• There might be a problem with the heating power supply and heating motor configuration.
• A stainless-steel reactor which is an important part of a vacuum emulsifying mixer is appeared to be disconnected with heat resistance wire or simply damaged that results in a stoppage of temperature rising.
• A computed configuration might be damaged so the user cannot observe the disturbance in temperature visually.
• Occasionally you encountered failure in the hydraulic lifting system. To troubleshoot failure of the hydraulic lifting system of the vacuum emulsifying mixer, you need to properly check the surface cleaning, appearance, and viscosity of hydraulic transmission oil. You can also assess the smell of transmission oil to get an idea if it is present in the right state. Check the temperature of the oil can also help to prevent serious damage or failure of the system.
• Always check if the delivery of energy is smooth without any leaking into the electrical cord.
• Always check if the blades of the motor are functioning correctly.

• When there is difficulty in mixing two- different phases, then always pay attention to the type of mixing, proper quantity of mixing ingredients, time, speed, and heating during the process. By considering these factors you mayachieve a homogenous mix.
• To avoid sedimentation, use a rapid high shear mixing with increased mixing time, as well as reduce the air incorporation with mixture.
• To avoid lumping and clogging is very important to manage the mixing correctly. This is a common problem that occurs when you deal with highly viscous material. To avoid this problem, you need to choose the right temperature and mixing speed. So, it can dissolve efficiently high viscosity ingredients in a larger concentration. 

9.How do you operate a vacuum emulsifying mixer?

To operate the vacuum emulsifying mixer, you need to follow certain assigned steps.

• Switch ON the power and heating button to pre-heat the oil and water pot.
• Monitor the emulsification equipment if valves are closed.
• When equipment is heated, add ingredients, and close the valves.
•   When the temperature of the process reached a required protocol, then stir the pots to attain a uniform temperature throughout the ingredients.
• After assuring the water and oil pot have estimated temperature up to 60 ° C or above, then open the heating valve of the vacuum emulsifying mixer.
• Adjust the speed of homogenization and homogenize the emulsification pot.
• Open the vacuum emulsifying tank when you observe a required temperature is achieved. By pressing the vacuum button on the touch screen panel, the upper valve of the vacuum emulsifying tank opens. The vacuum pumping is carried out when pressure is up to 0.2Mpa or more. After completing pumping, close the pumping valve. The vacuum is halted/ closed when the pressure is taken to 0.4Mpa.
• By using a hydraulic lifting system discharge the material and pour it over-discharging containers.
• Clean the equipment with the de-greasing solution and tap water (cooled and hot).

10.What do you know about the high shear homogenizing mixer?

A high shear homogenizing mixer is well-structured equipment used to mix, stir, emulsify, disperse as well as homogenize the immiscible material to form a uniform phase. The presence of the rotor and stator inside the homogenizing pot allows the material to pass through and create a shear.

This high shear ultimately results in the formation of a smooth emulsion, micro aeration, and perfect suspension in liquids. The high shear homogenizer is suitable to reduce the particles and stir the adhesive substances, chemicals, medicines, food and cosmetics, etc. The speed of fluid around the diameter of rotor is much higher than the mid of the rotor. The larger the velocity variation, the higher would be the shear. This machine is ideal for larger batches of high viscous ingredients such as gels, deodorant, and other sticky materials.

11.What do you know about the low-shear homogenizing mixer?

A low shear homogenizing mixers are characterized by mixing the ingredient without dispersing or reducing the particles' size.

This type of mixing machines is suitable for blending highly delicate and sensitive materials such as foods products, certain adhesives, or bio-pharmaceutically active compounds.

Pharmaceutical components such as protein, biological serums, cells are very sensitive to shear stress. Whenever you mix, always confirm the balance between homogeneity and protection of sensitive mixture. Because when protein or other biological components meet high shear forces, they will break and agglomerate which indicates the failure of product quality.

12.What are the major difference between high and low shear emulsifying mixers?

1) A high shear mix requires a lot of energy to shear the mixing particles. The impact of mixing disperses the particles and mix them freely. Whereas the low shear mixer allows the mixing procedures which are relatively ordered. The process of mixing occurs in a low speed and the material’s particles movements occur in an orderly manner throughout the mixer.

2)- The high shear mixing is ideal for those particles that use great energy to mix the cohesive material. Whereas the low shear mixing significantly ideal for free flowing and heat sensitive ingredients.

13.Does the vacuum emulsifying mixer comply with quality standards?

Vacuum emulsifying mixer is specially designed to meet high cGMP and FDA requirement necessary for pharmaceutical, food and beverages and biological laboratories. Adherence to the cGMP regulations, conforms the identity, potency, as well as quality of manufacturing operations.

cGMP also determines a  strong quality management systems with robust operating procedures also offers product quality deviations.

Additionally, vacuum emulsifying mixer has to comply with CIP and SIP system. The CIP or cleaning in place and SIP or Sterilization in place, are designed to bring automatic cleaning and sterilization of equipment without causing major disassembling or equipment or a workplace.

14.What is the optimum operational and temperature range provided by a vacuum emulsifying mixer?

The optimum temperature ranges this machine can produce is between 50-80 ⁰C.  Depending on the procedure this temperature can exceed up to 100 ⁰C. However, mixing that leads to a temperature rise to 105 ⁰C is not usually conducted in vacuum emulsifying mixer.  As previously mentioned for longer procedures that can increase the temperature exceeding 105 ⁰C, machines with integrated cooling systems are preferred that can control temperatures up to 150 ⁰C.

15.What safety measures need to be considered and are built in a vacuum emulsifying mixer?

To avoid occupational hazards several steps, need to be checked before operating the mixer.

• All the electrical wirings should be grounded.
• Functionality of valves and pressure gauge should be monitored.
• A number of built-in safety features are available to avoid mishaps during the manufacturing process such as coloured push buttons that reduce accidental activation and alarm system that indicates loosely held vacuum valves.
• The platform should be dry at all times to reduce chances of injury by falling.

16.How can you enhance the life of the vacuum emulsifying mixer?

All Accessories are made of high-quality stainless steel that makes it durable and functional for a number of years if properly maintained and taken care of. Following are the points that can further improve functional years of any equipment.

• Proper lubrication of gears and parts that runs over each other.
• Inspection on a regular basis of vacuum valves and pressure gauges.
• To improve mixing quality the distance between agitator and bowl should be checked every half a year.
