Static mixers are precision engineering machines used to combine fluid materials. As we know that fluid material is always present in any industry, such as the food and beverage industry, chemical industry, pharmaceuticals, plastic industry, etc.
This machine is able to mix various types of compounds; solid and liquid, liquid and liquid, liquid and gas compounds too. Static mixer manufacturers design these tools in various sizes depending on the application. Static mixers that are applied to the food and beverage industry are different from machine designs that are applied to the chemical and pharmaceutical industries.
They are also used to form a mixture of colloids. Colloid is an assorted mixture of two or more substances in which particles of the size between 1 and 1000 nm are dispersed evenly in the medium of other substances. The colloidal mixture is created due to the loss of energy from the mixing elements flowing through a mixing mechanism on a static mixer.
This mixer is static, meaning that this machine does not have a moving element such as a mechanical mixer. The mixing process with the static method aims to control the flow of compounds. So it will be perfectly mixed so as to form a homogeneous mixture.
Mixing elements experience two working principles in static mixers to become perfectly homogeneous mixtures. The working principle is laminar flow and turbulent flow.
The turbulent flow makes the mixer cut or cut the flow of compounds in a controlled manner. This is achieved by periodic rotation of internal components in a predetermined degree. And the number of times the action is taken. The speed and number of rotations can be controlled externally. Which will achieve the desired homogeneity of the mixture produced.
Using the principle of laminar flow, the material that needs to be mixed is repeated, divided into several thin layers using static mixing elements. And finally put together in the end. Thinness and number of layers can be controlled. Thus determining the level of mixing of the compound. This is achieved by increasing the number of static elements inside the engine and controlling the speed of material input externally.
A static mixer has no moving components. The static type uses certain chemical properties of the materials needed for mixing without using any pressure or force. When the liquid is mixed in the engine, the right amount of air pressure is sealed inside the unit. As a result, it has created a system that produces a certain amount of pressure needed in an environment. Such air pressure forces components and fluids to move and mix inside the engine. So, the point is that the mixing process in the static mixer occurs because of the perfect air pressure.
