What Are Mixing Tanks & How Does It Work?

Mixing tanks, or tank mixers, are industrial powerhouses harmonizing diverse substances into a seamless blend. Their secret? Impellers: rotating blades fueled by a motor. This dynamic duo crafts flow patterns inside the tank, helping substances to blend – which is this machine’s core purpose.

These tanks come in varied shapes, sizes, and configurations, tailored to specific needs:

  • Cylindrical Tanks: Versatile and common, these tanks, vertical or horizontal, host different impellers for varied flow directions and mixing intensity.
  • Square or Rectangular Tanks: Less frequent but handy for expansive surface areas, with easy cleaning due to impeller placement at corners or the center.
  • Cone-Bottom Tanks: Cylindrical with a conical bottom, facilitating smooth product discharge while preventing sediment buildup.
  • Jacketed Tanks: Sporting an outer layer filled with a temperature-controlling medium, they manage substance heat for optimal mixing performance.

In the mixing game, these tanks play hard and smart, ensuring a seamless blend every time.

What Exactly Are The Main Types And Components Of Mixing Tanks?

Easily optimizable and essential for many industries, tank mixers are crucial for diverse applications with varied types and components. Here’s a rapid-fire breakdown of some of their most important types and parts:

  1. Material: Mixing tanks come in varied materials—plastic, metal, or glass. Choosing wisely is key here. Plastic’s lightweight and customizable but can’t stand the heat. Metal is durable and heat-resistant yet prone to rust (Stainless steel resists rust and corrosion). glass is transparent and inert but handled with care—it’s fragile and pricey.
  2. Shape: Cylindrical, rectangular, square, or cone-bottom—the shape dictates flow, efficiency, and drainage. Versatile cylindrical tanks are the most favored choice, but others have their niche.
  3. Impeller: The impeller, the mixer’s powerhouse, spins the mix. Types like propellers, turbines, high-shear, or helical ribbons cater to different fluids. Propellers suit low viscosity, and turbines tackle tough, high-viscosity products. High-shear excels in intense mixing, ideal for emulsifying or homogenizing. Helical ribbons handle the viscous and solid mix surprisingly well.
  4. Agitator: The agitator housing the rotating impeller is crucial in mixing tanks. Three types have their essential roles: top-entry for high-viscosity fluids, side-entry for low-viscosity mixes, and bottom-entry for fluids prone to settling. The location of the shaft and motor dictates the choice—top, side, or bottom.
  5. Baffle: A vertical plate to squash swirling and enhance turbulence. Essential for cylindrical tanks with axial flow impellers.
  6. Sparger: Spargers inject gas or air into tanks, boosting mixing with bubbles or aeration. They tweak substance properties—pH, oxidation, or reduction potential. Submerged types, static or dynamic, sit inside; external ones, venturi or educator, are outside – depending on how the mechanism injects the gas.
  7. Temperature Control Jacket: The jacket regulates substance temperature, whether full or partial. Critical for optimal mixing and product quality.
  8. Smart Control & Sensors: Sensors and controllers monitor and regulate the operation. Analog or digital, they keep tabs on temperature, pressure, level, and more – manual or automatic adjustments can be set.

What Can You Mix In A Mixing Tank?

These versatile vessels blend liquids, solids, gases, powders, and more – handling substances with varying properties, from density to reactivity. Here’s a sneak peek into what mixing tanks can do:

  • Food & Beverage: Perfect for formulating juices, sauces, soups, yogurts, and more. Achieve the ideal taste, texture, color, and aroma while preventing separation or spoilage.
  • Pharmaceutical & Cosmetic: Mix creams, lotions, syrups, and more with precision. Ensure uniformity, stability, efficacy, and safety in pharmaceutical and cosmetic products.
  • Chemical & Petrochemical: From acids to fuels, these tanks facilitate chemical reactions. Control temperature, pressure, pH, and concentration for various products.
  • Industrial Processes: Beyond the obvious, mixing tanks improve processes like water treatment, wastewater treatment, anaerobic digestion, and fermentation.

What Advantages & Disadvantages Do They Have?

As with most machinery, the advantages and disadvantages of mixing tanks vary based on application and desired results. Here are some key examples to give you a better idea:


  • Elevates production quality, consistency, and efficiency while optimizing resource and energy use.
  • Prevents separation, sedimentation, or spoilage, incorporating diverse ingredients for varied applications.
  • Facilitates chemical reactions, controlling temperature, pressure, pH, and concentration for precision.
  • Enhances industrial processes like water treatment, wastewater treatment, and fermentation.
  • Customizable with material, shape, size, impellers, agitators, baffles, spargers, jackets, sensors, and controllers.

Potential Disadvantages

  • High upfront, operational, and maintenance costs, particularly for large-scale or complex applications.
  • Demands substantial space, especially with large or multiple tanks.
  • Carries safety and environmental risks, including leaks, spills, explosions, fires, and contamination, especially with hazardous substances.
  • Prone to performance variations influenced by substance properties, tank design, impeller type & speed. The same can be said with the baffles’ or spargers’ presence, tank temperature and pressure, and mixing process duration and frequency. It demands meticulous consideration and adjustment for each application.

How Do You Choose The Ideal Mixing Tank For Your Application?

Choosing the ideal mixing tank demands thoughtful consideration. With these tips, navigate the complexities and find the tank that aligns with your needs:

  1. Assess Fluid Rheology: Dive deep into your fluid’s unpredictable reaction under pressure. Each fluid demands a personalized approach. Handpick a tank that syncs with its viscosity, elasticity, and thixotropy.
  2. Define Mixing Purpose: Tailor your tank to the task. For blending liquids, pick radial flow turbines. Likewise, for dissolving solids, choose axial flow propeller impellers. Emulsifying immiscible liquids would need high-speed rotor-stator mixers.
  3. Gauge Scale of Operation: Size matters with your fluid’s volume and flow rate – scaling up impacts tank size, shape, and mixer power. But doing so isn’t a simple size increase; consult an expert or use scale-up methods for optimal design.
  4. Mind the Budget: Your money, your choices – but know that plastic tanks are cost-effective but less durable, while stainless steel is pricier but corrosion-resistant. Balance your budget with materials, quality, and features that suit your needs.
  5. Prioritize Safety: Don’t cut corners on safety; adhere to industry standards. Pick non-sparking or inert materials, pressure relief valves, and grounding systems if dealing with hazardous materials. Likewise, choose sanitary materials for food, pharmaceuticals, or cosmetics and ensure easy cleaning.

Is It Safe To Operate A Mixing Tank?

Tank mixers may seem like a breeze for a well-trained operator to master – still, it’s a skill of precision and safety, and the only hands touching the tool should leave zero room for mistakes. Noticeably, the type of liquid that you work with will also define the overall difficulty experience, but here are just a few examples of some safety approaches that almost all tanks would follow:

  • Fortify Your Ground: Anchor that tank & lock down the drums—no room for wobbles.
  • Wire Control: No loose ends. Tighten those electrical connections like a pro.
  • Safety Collection: Arm your mixer with safety features—it’s the hazard zone, after all.
  • Tool for the Task: Pick the right gear for the substance.
  • Gear Up: Don the safety gear; make sure your team suits up, too.
  • Hands-off Policy: Mixer’s spinning? Keep your hands out—no tampering should be allowed.
  • Power Down, Then Clean Up: Unplug before you dive in – clean smart, not wet.
  • Tank Lockdown: No entry until that mixer’s on a total timeout. Safety is the name of the game.
  • Watch Like a Hawk: Use sensors and your judgment to regulate temperature, pressure, and substance properties.
  • Troubleshoot Swiftly: Address any mixer glitches promptly—leaks, vibrations, or poor mixing quality. Stop, consult the manual, or reach out to technical support for assistance.
