Bottom-entry mixers are widely used in industries such as chemical processing, food and beverage, pharmaceuticals, wastewater treatment, paper and pulp production, and oil and gas extraction. Featuring an impeller mounted at the bottom of the tank, these mixers rotate to create a vortex that draws liquid downward and disperses it radially, forming a homogeneous mixture. Their key advantages include efficient mixing in large tanks, easy access for maintenance, space-saving design, versatility, and energy efficiency. AxFlow supplies bottom-entry mixers for diverse applications, offering expert guidance from seasoned process engineers and independent access to leading global process technology providers.

How Bottom-Entry Mixers Work
Bottom-entry mixers are a popular type of mixer used in many industries. Their working principle is based on a mixing rotor attached to the lower end of the shaft and mounted at the bottom of a tank or vessel. The mixer rotates at the bottom, generating a swirling force that pulls the liquid suspension downward toward the rotor. The rotor then disperses the liquid or suspension radially, creating a homogeneous mixture.
The rotor of a bottom-entry mixer can come in various designs such as propellers, turbines, or flat blades. Each rotor type suits different applications and can generate distinct flow patterns. For example, propeller rotors are ideal for low-viscosity fluids, while turbine rotors are better suited for high-viscosity fluids. The shaft is powered by an electric motor or other energy source, producing the rotational mixing force. The mixer’s speed and power can be adjusted to achieve desired mixing results.
Bottom-entry mixers are often used in large tanks or vessels in industries like chemicals, pharmaceuticals, and food processing. They are ideal for mixing fluids requiring gentle agitation, such as suspensions or emulsions, and are capable of handling viscous materials.
Advantages of Bottom-Entry Mixers
Bottom-entry mixers offer several benefits compared to other types of mixers, making them a popular choice across various industries. These advantages include:
- Efficient mixing of materials in large tanks or vessels, ensuring consistent and uniform results, which is crucial for maintaining the high quality of the final product where ingredients must be well mixed.
- Easier access and maintenance due to their position at the bottom, reducing downtime and maintenance costs.
- Space-saving design, making them ideal for facilities with limited space and increasing production area capacity without needing additional floor space.
- Customization to specific mixing requirements such as speed, mixer design, and flow rates. This versatility allows them to be adapted to various industries including pharmaceuticals, food and beverage production, and chemicals.
- Energy-efficient motors and rotor designs that reduce energy consumption and operational costs.
Industries and Applications Using Bottom-Entry Mixers
Bottom-entry mixers are extensively used across a wide range of industries and processes. In the chemical industry, they play a vital role in mixing chemicals, solvents, and raw materials in applications such as polymerization, fermentation, and liquid-liquid extraction. In the food and beverage sector, these mixers are employed to blend ingredients in products like sauces, marinades, and dressings, as well as to process liquids such as dairy products, juices, and other beverages. The pharmaceutical industry relies on them for blending, emulsifying, and homogenizing products including vaccines, antibiotics, and creams. Bottom-entry mixers are also integral to wastewater treatment, pulp and paper production, and oil and gas extraction. Thanks to their adaptable design and the option for energy-efficient motors and impellers, these mixers can be customized to meet specific process requirements while reducing energy consumption and operational costs.
