What is lab emulsifier?

Lab emulsifier is an apparatus that shears, disperses, and impacts materials through the high-speed rotation of the homogenizing head connected to the engine. The material treated by the laboratory emulsifier will become more delicate, prompting the oil and water to melt.

The lab emulsifier is used to test a small amount of cream material whether its performance can reach the design requirements, and to pave the way for the industrial production of batches. This machine has the advantages of small size, easy to move, simple operation, and no requirements for the site.

In the laboratory emulsifier, all the parts in contact with the material are made of high-quality stainless steel. The internal joints of the pot are smoothly arced, and the bottom of the pot and the dumping of the material ensure that there is no residual material in the pot. It is suitable for fine emulsification, high-quality dispersion, and high-efficiency mixing. All-round scraping wall stirring material tumbling without dead angle.

The lab emulsifier can be used in scientific research, schools, small institutions, and other places. It can be used by just placing it horizontally. The lab emulsifier mixer is compact and easy to move, which is a piece of good equipment for emulsifying small output materials.

Working principle of lab emulsifier

The working head of the lab emulsifier has a unique structure. It uses the rotor driven by the motor at high speed, rotating at high linear velocity, producing strong liquid shear force and violent high-frequency mechanical effect. Then, it prompts the experimental fluid materials to shear and disperses each other through the rotor and stator under the action of huge centrifugal force, so that the experimental materials are subjected to shearing, tearing, and mixing up to tens of thousands of times per minute to achieve the effect of dispersion and homogenization. The precision fit of rotor and stator, claw structure of working head (made of forged rotor and stator), bidirectional suction, and high shearing efficiency. Different sizes of working heads are designed to meet different experimental needs.

Laboratory emulsifiers are generally high shear emulsifiers. Intermittent high shear dispersion emulsification homogenizer through the rotor high-speed smooth rotation to form a high-frequency, strong circumferential tangential velocity, angular velocity, and other comprehensive kinetic energy efficiencies. Under the action of the stator, the stator and rotor form a strong reciprocal hydraulic shear, friction, centrifugal extrusion, liquid flow collision, and other comprehensive effects in a reasonably narrow gap. Materials in the container cycle reciprocate the above work process and finally obtain the product.

Intermittent high shear working process

a. Under the action of centrifugal force generated by the rotor rotating at high speed, the material is simultaneously sucked into the working cavity along the axial direction from the upper and lower feeding areas of the working head.

b. The strong centrifugal force throws the material from the radial direction into the narrow and precise gap between the fixed and rotor. The material is simultaneously subjected to centrifugal extrusion, impact, and other forces to make it carry out preliminary dispersion and emulsification.

c. The outer end of the rotor rotating at high speed generates a linear speed of at least 15m/s or more, up to 40m/s, and forms strong mechanical and hydraulic shear, liquid layer friction, and impact tearing, so that the material is fully dispersed, emulsified, homogenized, broken, and shot out through the stator slot at the same time.

d. The material is constantly shot out from the radial direction at high speed and changes the flow direction under the resistance of the material itself and the vessel wall. At the same time, under the action of the upper and lower axial suction force generated in the rotor area, two strong turbulent flows are formed on and off. After several cycles, the material is dispersed, emulsified, and homogenized at last.

Feature of lab emulsifier

a. Small size, reasonable and compact structure, easy to move.

b. Simple operation. High rotational speed, safe and reliable operation.

c. No requirement for working site.

d. High shear emulsifying head device, no dead angle emulsification.

e. Special CNC processing emulsifying head, not easy to break and deformation.

f. Convenient speed regulation and digital display of operating status function assure collecting experimental data.

Use of lab emulsifier

In biopharmaceutical, food, daily chemical, new materials, and other industries, research and development is the driving force for these industries to maintain core competitiveness. In the research and development of these industries, the small high-shear emulsifier is often required in the laboratory mixing and stirring heating equipment. Through the laboratory vacuum emulsifier's strong centrifugal extrusion, shear and other mechanical force, and mature process formula under the joint action, the experimental materials uniformly fine mixing, dispersion, homogenization, and emulsification to achieve a satisfactory finished product effect.

The operating components of the lab emulsifier are the main pot stirring system, the main pot homogenizing system, the main pot lifting system, the secondary pot stirring system, and the vacuum pump system. It can be controlled by the buttons on the panel, which can control the lighting and extinguishing, the operation of the main pot stirring, the operation of the main pot homogenizing, the operation of the secondary pot stirring, the operation of the vacuum pump and the heating of the main and secondary pots.

a. Turn on the power.

b. Add material to the oil-water pot.

c. Close the lid of the oil-water pot.

d. Heating and stirring the oil-water pot.

e. Close the lid of the homogenizer, close the other valves on the lid and open the vacuum valve for vacuuming to absorb the material.

f. Heating homogenizing pot, temperature adjustable.

g. Homogenize and stir the emulsified through-difference material. When the time is up, stop heating.

h. Open the material valve to release the material.

i. After cleaning, you can raise the lid of the pot to dump the drainage and then close the lid.

j. Cycle the previous work.

Precaution of lab emulsifier

a. Power supply voltage must match, and pay attention to grounding.

b. Every time after the motor is wired, or when it is not used for a long time, it should be started for a test run. Confirm that there is no error before allowing the homogenizer to operate normally.

c. A spot test should be performed before each stirring start to check if there is any abnormality in the stirring scraping wall. If there is, it should be excluded immediately.

d. Before stirring and vacuuming, make sure to check whether the pot is flat against the lid and whether the pot mouth and material mouth cover are covered tightly and sealed reliably.

e. Before flushing nitrogen into the homogenizing pot, the ball valve under the vacuum gauge should be closed to prevent the vacuum gauge from being broken.

f. Before shutting down the vacuum pump, the ball valve on the vacuum system purifier should be closed first.

g. The vacuum pump can be started only under the sealed condition of the homogenizer. If there is a special need to start the pump by opening the atmosphere, the operation should not exceed 3 minutes.

h. The purifier is connected to cooling water.

i. If you want to open the lid of the pot and the cover of the material outlet, make sure to do it when there is no vacuum pressure inside the pot. If there is vacuum pressure in the pot, you should close the ball valve on the purifier and turn off the vacuum pump. Then open the bleeder valve on the lid so that there is no vacuum pressure inside the pot. Open the lid only after these operations have been performed.

j. The vacuum pump is strictly prohibited to run without oil. It is forbidden to block the exhaust port when the pump is running.

k. The equipment must be disconnected from the power supply before any maintenance or cleaning is performed.

l. Never put your hand into the pot when the equipment is running to prevent accidents.

m. If there is a strange noise during operation, the machine should stop running immediately. You should check to remove the fault before starting the machine.
