Question 1

How does a liquid mixing machine work?

Accepted Answer

The liquid mixing machine is composed of motor, reducer, bearing, swing shaft, agitator and other components. The motor is driven by a reducer to make the swing shaft rotate, and the swing shaft drives the stirrer to rotate, thereby forming a strong stirring energy to mix liquid and solid together. The impeller of the agitator adopts a special design, which can circulate the liquid in multiple dimensions, and use the rotational kinetic energy of the swing shaft to quickly and evenly mix the liquid and the solid.

In addition, the mixer can also achieve different mixing effects by controlling the rotation speed of the swing shaft. Generally speaking, the faster the rotation speed of the swing shaft, the better the mixing effect and the finer the mixture; the slower the rotation speed of the swing shaft, the worse the stirring effect and the coarser the mixture.

Question 2

What are the different types of industrial agitators？

Accepted Answer

In liquid mixing machines, the role of the agitator is very important. It is the key factor for effective liquid mixing. Choosing a suitable agitator will help us obtain high-quality products in a short period of time. Next, Immay will present 4 types of agitators that are widely used in daily use.

1. Three-blade agitator

Three-bladed impellers are often used for mixing low viscosity fluids. When stirring, the fluid is sucked in from the top of the paddle, and discharged in a cylindrical spiral form from the bottom. The fluid reaches the bottom of the container and then returns to the top of the paddle along the wall, forming an axial flow. The degree of turbulence of the fluid is not high during stirring, but the circulation volume is large.
The diameter of the three-lobe blade is usually small, but the mixing speed is fast, and it is easy to manufacture. It is suitable for the application scene with low viscosity and large flow rate. The liquid dispersion mixer can use the low stirring power to obtain better mixing effect through the three-lobe blade rotating at high speed. Although the circulation performance of the three-blade stirring paddle is good, its shearing effect is not large. It belongs to the circulation type stirring paddle. It is mainly used for uniform mixing of liquid-liquid and liquid-solid system products in the industries of medicine, food, chemical industry and cosmetics.

2. Dispersion disc agitator

Dispersing discs are mainly used for crushing, stirring and grinding of liquid, emulsion and liquid-solid products in paint, pigment, dye, paint, ink, adhesive, food, medicine, daily chemical and other industries.
The dispersing disc is connected to the main shaft of the high-speed dispersing machine. When the main shaft of the disperser is running at high speed, the top and bottom of the dispersing disc are in a rotating state, and at the same time, a turbulent zone will be formed at the edge of 2.5-5mm. The upper and lower serrations of the dispersing plate perform high-speed shearing, impacting, crushing and dispersing of coatings, paints, dry powder, solid-liquid and other materials, so as to achieve the state of rapid mixing, dissolution, dispersion and refinement.
Advantages of dispersing disc

High strength, strong and durable.
The specifications can be flexibly adjusted according to the power of the disperser, which is simple and practical.
Easy to replace, easier to clean, and pollution-free.

3.3 Frame agitator

There are two types of frame impellers: straight blades and folded blades. The blade surface of the straight blade is perpendicular to the direction of rotation, while the blade surface of the folded blade forms an oblique angle with the direction of rotation. The straight paddle mainly makes the material flow in the tangential direction, and the folded paddle can not only make the material do circular motion, but also make the material move up and down, which is more sufficient than the straight stirring effect. Under the same power, because the power consumption of the axial flow blade is less than that of the radial flow blade, the folded leaf frame type impeller is used more.
According to the mixing process and the volume of the container, the frame-type impeller can be designed with single-layer, double-layer or multi-layer blades. The frame-type impeller can make the stirring medium flow in the axial, radial and circumferential directions at the same time, so that it can reach a certain stirring intensity in a short period of time, meet the requirements of uniform and sufficient mixing, and have low hydraulic loss. It is widely used in the uniform mixing of high-viscosity products in food, medicine, cosmetics, and chemical industries.

4 Homogenizer agitator

The high-shear homogenizer is a set of precision stainless steel stator-rotor system. Due to the high tangential velocity generated by the high-speed rotation of the rotor and the strong kinetic energy brought by high-frequency mechanical effects, the material is subjected to strong mechanical and hydraulic shearing, centrifugal extrusion, liquid layer friction, impact tearing and other comprehensive effects in the narrow gap between the stator and the rotor to form suspoemulsions, emulsions and foams. So that the immiscible solid phase, liquid phase, and gas phase are uniformly and finely dispersed and emulsified in an instant under the combined action of corresponding mature technology and appropriate amount of additives. After high-frequency cycles, stable high-quality products are finally obtained.
The high-shear homogenizer has a large batch processing capacity and is suitable for industrial continuous production. It can be widely used in the large-scale production of mayonnaise, lipstick, ointment, paint, pesticides and other products in the food, pharmaceutical, cosmetic, chemical and other industries

Question 3

How to choose the right liquid mixing machine for you

Accepted Answer

If you are struggling to choose a suitable liquid mixer, we recommend that you consider the following four dimensions based on your production needs:

Mixing capacity

Corrosion resistance requirements

Process requirements

Hygiene requirements

1. Mixing capacity
① Mixing Tank With Agitator can also be called a liquid mixing tank, with a volume of 50-5000L.
Usually, if the capacity is less than 500L, a mobile caster design can be used instead of a platform to facilitate movement.If the capacity is greater than 500L, one or more continuous platforms can be used, which can achieve large-scale industrial assembly line production.

② Movable-lifting-homogenizer-mixer without a stirring container can also be called a mobile mixer (including low-speed mixer, high-speed disperser, and high shear homogenizer). The conventional mixing volume is less than 500L.

2. Corrosion resistance requirements

The corrosion resistance levels for liquid mixers are categorized as low, medium, and high. The available materials include carbon steel liquid mixers, stainless steel liquid mixers, and PP (polypropylene) liquid mixers, respectively.
① Stainless steel is a metallic material with excellent corrosion resistance. It can be used for a long time in acidic media such as sulfuric acid, hydrochloric acid, nitric acid, and hydrofluoric acid with a concentration of less than 50%. In addition, stainless steel also has good wear resistance and high temperature resistance, so it is widely used in chemical, pharmaceutical, food and other industries.
② PP (polypropylene) is a thermoplastic with excellent acid resistance. It can be used for a long time in acidic media such as sulfuric acid, hydrochloric acid, nitric acid, and hydrofluoric acid with a concentration of less than 90%. In addition, polypropylene also has good corrosion resistance, wear resistance and high temperature resistance, so it is widely used in chemical and other industries.

3. Process requirements

If the product adopts the cold mixing process, there is no need for heating and cooling during the mixing process, and a single-layer liquid mixing machine can be used. If the product adopts the hot mixing process, heating and cooling are required during the mixing process, so a three-layer liquid mixing machine is required for mixing. According to the needs of heating sources, we can provide electric heating three-layer liquid mixing machines and steam heating three-layer liquid mixing machines.

4. Hygiene requirements

According to hygiene requirements, it can be divided into open lid liquid mixing machine and sealed liquid mixing machine. In the food, medicine, and cosmetics industries, hygiene requirements are usually relatively high. We can use sealed liquid mixing machines to produce products. Sealed liquid mixing machines can effectively prevent dust and bacteria from entering the tank to pollute products. However, in the chemical industry, due to the low hygiene requirements for chemical products, We can use open lid liquid mixing machines for production.
