What is a Stirring tank / Mixing Tank?

A mixing tank is a container used to blend, mix, and stir liquids or powders, widely utilized in chemical processing, food and beverage production, pharmaceuticals, cosmetics, and environmental engineering. It is essential for promoting reactions, ensuring uniform composition, and enhancing heat exchange efficiency.

A mixing tank consists of a main tank, an agitator, and an impeller (blade). The impeller rotates to create liquid flow, ensuring efficient mixing. Tanks come in various materials, such as stainless steel (SUS304, SUS316), glass-lined steel, and polyethylene, chosen based on the application.

Different mixing methods include propeller, turbine, paddle, and anchor types, each suited for specific viscosities and purposes. For example, propeller mixers work well for low-viscosity liquids, while anchor mixers are better for high-viscosity materials.

Mixing tanks play a crucial role in homogenization, emulsification, dispersion, and reaction facilitation, contributing to higher production efficiency and product quality stability.

Application of Stirring tank / Mixing Tank

✅ Chemical Industry – Promoting Chemical Reactions
Example: Manufacturing plastics and paints
Mixing tanks are used to blend raw materials evenly and facilitate chemical reactions. In polymer synthesis and adhesive production, controlled mixing ensures high-quality output by maintaining uniform temperature and concentration.
✅ Food & Beverage Industry – Liquid Mixing
Example: Juice and dairy production
Mixing tanks help homogenize fruit juice and milk. For example, in yogurt production, consistent stirring ensures that lactic acid bacteria mix well with raw ingredients, enabling smooth fermentation.
✅ Pharmaceutical & Cosmetic Industry – Emulsification & Dispersion
Example: Lotion and cream manufacturing
In cosmetic production, lotions and hand creams require oil and water to be blended into a stable emulsion. Mixing tanks with impellers create fine emulsions, ensuring smooth and uniform textures.
✅ Environmental Technology – Wastewater Treatment
Example: Water purification plants
Mixing tanks play a crucial role in treating wastewater by adding chemicals to coagulate and settle contaminants. Uniform mixing helps pollutants settle efficiently, leading to effective purification.
✅ Biotechnology – Fermentation Process
Example: Brewing beer and biofuel production
Fermentation tanks, a type of mixing tank, are used for cultivating microorganisms. In beer brewing and biofuel production, stirring ensures that yeast and bacteria receive oxygen and nutrients, optimizing fermentation.
