Electric blender application
Electric blender is a device that makes liquid and gas media that force convection and uniform mixing. The type, size, speed, power, and other parameters of the blender have an important influence on the effect of mixing and stirring the medium. Different stirring processes need to be operated by different electric stirring devices.
a. Determine the purpose of stirring
Confirm what kind of operation is being performed, such as liquid-liquid mixing, solid-liquid suspension, gas-liquid, or liquid-liquid dispersion. Confirm whether you need to achieve process purposes such as heat transfer, absorption, extraction, dissolution, crystallization, etc. You should choose the stirring paddle form according to the process characteristics.
b. Calculation of mixing operation power
Mixing power is the power needed to carry out the mixing process.
Reference formula: power = power quotient * liquid density * 3 times the number of revolutions * 5 times the pulp diameter.
The calculation of power quotient is complicated, and is related to tank diameter, pulp diameter, paddle width, angle, number of layers, viscosity, number of baffles, and baffle size.
c. Motor power
The calculated value of motor power should be greater than or equal to 1.5 times the mixing operation power.
d. Determining the minimum critical mixing speed
This rpm is the minimum rpm to meet the mixing purpose rather than the critical rpm of the mixing shaft.
e. Other considerations
a) Select and calibrate the stiffness and strength of the mixing shaft and paddle according to the power.
b) When equipped with a reduction device, you should consider the use factor of the reducer and the bearing capacity of the reducer.
c) For slender shafts, you should have to consider adding support, middle or bottom support.
d) Consider the installation method, whether it is a top entry or bottom entry, or side entry.
e) Choose the support.
f) The choice of sealing form, whether packing or machine seal.

Type of electric blender
Electric blenders are often used in fine chemical experiments in order to make the reaction uniform and complete and to create good operating conditions. There are two types of electric mixers commonly used in laboratories, they are electro-mechanical blenders and electric magnetic blenders.
Electro-mechanical blenders
Electro-mechanical blender, which is also known as electronic blender, is a motor-driven, mechanically driven stirring device, and the stirring speed can be adjusted arbitrarily through electronic transmission or an external voltage regulating transformer.
Electric magnetic blender
Electric magnetic blender is a stirring device driven by an electric motor and driven by magnetic force. Usually, the electric magnetic stirrer used in the laboratory is also equipped with a heating device, which is called magnetic heating stirrer. When used, there should be grounding protection. The stirring magnet must be rinsed clean, and stirring should be stopped when placing and removing the stirring magnet. The speed of stirring should be slow to fast at the beginning. If the solution is spilled on the disk, the power should be turned off immediately and the solution should be cleared off in time to avoid the solution from penetrating the electric heating wire and the motor part.
How to select the electronic blender for laboratories?
There are various types of electronic blenders, and their parameters such as type, size, speed, and power will have an impact on the mixing effect of the stirring medium. The following are the parameters to consider when selecting an electric blender.
The electric blender
A. Select the power and speed according to the experimental requirements
The viscosity of the liquid has a great influence on the mixing state. Different viscosity of the liquid stirring need to choose different types of stirring, stirring paddle, and stirring power. If the liquid viscosity is large, you should choose a high-power electric blender. Low-speed electric blenders are used for mixing large volumes of liquids, while high-speed electric blenders are used for small volumes of liquids. High-quality electric blenders have a wide range of speed settings and high-speed accuracy.
B. Select the stirring paddle according to the stirring requirements
There are various types of stirring paddles for electronic blenders, such as four-blade, one-blade, centrifugal, fan-blade, anchor, dissolving, etc. Different stirring paddles are suitable for different speeds and liquid types. For example, four-blade, one-blade and centrifugal agitators are suitable for medium to high speeds and low or medium viscosity mixing materials, while fan-blade and anchor agitators are suitable for medium to high viscosity mixing materials. A single electric mixer may be equipped with several different stirring paddles, which you can choose according to your needs.
C. Stirring capacity
Each electric blender has a limited maximum stirring capacity, so please check the relevant parameters when using it. Choose a suitable container for mixing and make sure the stirring paddle is fully immersed in the liquid.
D. Stirring working time
The stirring time also has a great impact on the experimental results. A long stirring time helps the stabilizer and other additives to spread evenly. A good quality electronic blender should have the flexibility to set the working time, usually in the range of 0-99 minutes.
E. Quality of the electric blender
The principle of electronic blender and magnetic blender is different. The electric blender is driven by the motor to drive the stirring paddle to achieve stirring. Magnetic blenders are used to achieve stirring by constantly changing the polarity of the two ends of the base through the property that magnetic substances are homogeneous and repulsive, and they generally have a heating function.
When choosing an electronic blender, the quality of the motor has the greatest impact on the overall quality of the instrument. It is also important to take into account the overall material and workmanship of the instrument, as well as whether the instrument control system is working properly.
F. Brand and after-sales service
As with other laboratory instruments and equipment, it is important to choose a brand with good after-sales service on the basis of meeting the basic functional and parametric requirements. Laboratory instruments and equipment require a high-precision operation. Once the instrument fails, it will have a serious impact on the experimental results. Therefore, the choice of a quality product can reduce the rate of instrument failure, while good after-sales service can ensure that the first time the problem is solved to reduce the experimental losses. ANTITECK provide quality products and excellent after-sales service to our customers worldwide.

c. Turn on the power, turn on the power switch, then turn on the timer. Turn on the respective speed switch from slow to fast according to the requirement. To ensure safety, be sure to use the grounding wire.
d. When using, if you find that the electric mixer stick is not centered and the stirring is unstable, please readjust the screwing chuck to make the stirring concentric. If you use a triangular flask, you should align the stirring bar to the center and then turn on the machine to stir.
