An agitator mixing tank is the workhorse vessel used to blend, dissolve, suspend and maintain product uniformity before filling. Unlike a high-shear emulsifier, it focuses on bulk circulation with low to medium shear, which protects sensitive ingredients while ensuring batch repeatability.

Its role in blending, dissolving, suspending and maintaining product uniformity makes it essential for sauces, syrups, shampoos, detergents, and pharmaceutical liquids. Food and beverage manufacturers, cosmetic manufacturers, sauce and condiment producers, and chemical plants use it as both a process tank and a buffer before the filler. The key is matching agitator type and tank geometry to viscosity and process goal.

A propeller that works at 1,000 cP will stall at 80,000 cP. King-Pack’s customized mixing tank solutions are configured around actual product viscosity, batch size, and downstream filling requirements rather than a one-size-fits-all design. This guide explores the different types of agitator mixing tanks, their applications, and key considerations when selecting equipment for industrial production.

What Is an Agitator Mixing Tank?

A mixing tank with agitator consists of a vessel that stores and processes material and an agitated mixing system that moves it. The motor drives the shaft and impeller. The impeller creates fluid circulation — axial flow for top-to-bottom turnover, radial flow for side-to-side shear, or combined flow for full-tank blending.

Mixing can combine liquids, dissolve powders like sugar or salt, or keep solids suspended like spices or TiO2. Optional systems provide heating, cooling, vacuum and automatic control via PLC.

A standard agitated mixing tank is mainly used for blending and circulation. Products requiring intense particle reduction or stable emulsification — such as cream, lotion, mayonnaise — may need a high shear mixer or vacuum emulsifying mixer. Using the wrong tool either damages the product or fails to create a stable emulsion.

How Does an Agitator Mixing Tank Work?

Typical process in an industrial mixing tank:

Raw Material Feeding → Agitator Start-Up → Bulk Material Circulation → Ingredient Blending or Dissolution → Heating or Cooling if Required → Quality Inspection → Discharge or Transfer

The motor rotates the agitator shaft through a gear reducer. The impeller generates flow patterns based on its design. Baffles may be used to reduce vortex formation and improve top-to-bottom mixing, especially with low-viscosity liquids.

Mixing speed and time depend on viscosity, tank size and product requirements. For example, a 1,000 L liquid mixing tank with 5,000 cP syrup may run at 60 rpm for 15 minutes, while a 500 L sanitary mixing tank with 50,000 cP gel needs an anchor agitator at 20 rpm for 40 minutes.

For food plants, heating is often via jacket with hot water at 85°C; cooling via chilled water at 7°C. Temperature sensors ensure the batch never exceeds the heat sensitivity limit.

Main Components of an Agitator Mixing Tank

A complete stainless steel mixing tank system includes:

• Stainless steel tank body, single-wall or jacketed

Types of Agitators for Mixing Tanks

Choosing agitator type is the most important decision for an industrial agitator tank. Multiple agitators may be combined in one tank, for example anchor plus high-speed disperser, depending on process.

Propeller Agitator

Suitable for low-viscosity liquids below 2,000 cP, rapid circulation, liquid-to-liquid blending. Used for beverages and cleaning liquids, water-like chemical blending.

Paddle Agitator

Suitable for gentle mixing, medium-viscosity products up to 10,000 cP, products requiring limited shear such as fragrances added to shampoo.

Turbine Agitator

Suitable for liquid blending, solid suspension, gas-liquid dispersion, processes requiring stronger turbulence. Generates both radial and axial flow.

Anchor Agitator

Suitable for creams, sauces, gels, medium- and high-viscosity products 10,000–80,000 cP. Scrapes near wall, prevents dead zones.

Frame Agitator

Suitable for thick liquids, pastes, products requiring full-tank circulation. Larger diameter than paddle, better turnover for 50,000–150,000 cP.

Scraper Agitator

Suitable for products that stick to the tank wall, heated creams and sauces, high-viscosity materials. PTFE scrapers maintain contact during heating.

Agitator Type	Suitable Viscosity	Typical Application	Main Function
Propeller Agitator	<2,000 cP	Beverage blending, CIP solution, thin solvents	High-speed axial circulation
Paddle Agitator	1,000–15,000 cP	Syrup mixing, light lotion, flavor blending	Gentle bulk blending
Turbine Agitator	1,000–20,000 cP	Solid suspension, neutralization, chemical blending	Turbulent mixing and dispersion
Anchor Agitator	10,000–80,000 cP	Sauce, cream base, gel	Wall scraping and full turnover
Frame Agitator	20,000–150,000 cP	Paste, thick detergent, ketchup base	Full-tank circulation
Scraper Agitator	30,000–200,000 cP	Heated sauce, cosmetic cream, caramel	Prevents burning and wall buildup

For mixing vessel with agitator designs, anchor plus disperser combination is common when you need both viscosity handling and powder wetting.

Mixing Tank Bottom and Vessel Design

Tank geometry affects drainage, cleaning, and mixing efficiency.

Flat Bottom

Simple structure, suitable for general liquid blending, economical configuration. Harder to drain fully.

Sloped Bottom

Improves drainage, guides product toward discharge valve, reduces residue to <0.5%.

Cone Bottom

Suitable for complete discharge, useful for products containing solids or sediment like dressings with herbs.

Dished Bottom

Supports smooth circulation, reduces material accumulation in corners, suitable for sanitary applications and CIP. Most sanitary mixing tank designs use 2B or electropolished interior Ra<0.8 μm.

Stainless Steel Mixing Tank Materials

Commonly available options for stainless steel mixing tank construction:

SS304

Suitable for many general food, beverage, cosmetic and industrial liquid applications. Cost-effective, good corrosion resistance for neutral pH products.

SS316L

Suitable when greater corrosion resistance or stricter hygienic requirements are needed, such as salty sauces, acidic dressings, chloride-containing detergents.

Material selection depends on product composition, acidity, salt content, cleaning chemicals, production standards, and corrosion risk. For pH <4 or chloride >200 ppm, SS316L is recommended. For more information on stainless steel grades, refer to the British Stainless Steel Association.

Applications of Agitator Mixing Tanks

Food and Beverage

Examples: sauces, syrups, marinades, dressings, beverages, dairy products, liquid seasonings. A jacketed mixing tank with scraper agitator handles tomato sauce at 30,000–60,000 cP.

Cosmetics and Personal Care

Examples: shampoo, conditioner, liquid soap, lotion, gel, cleanser. Requires foam control and often vacuum to avoid bubbles.

Pharmaceutical Products

Examples: syrups, liquid preparations, suspensions, gels, cleaning solutions. Needs 316L and documentation for GMP.

Chemical Products

Examples: detergents, lubricants, paints, coatings, solvents, fertilizers, industrial chemicals. May need explosion-proof motors and ATEX rating.

Agitator Mixing Tank vs Emulsifying Mixer

The main difference is the type of mixing each machine performs. An agitator mixing tank is designed for blending, dissolving, and maintaining product uniformity, while an emulsifying mixer uses high shear to create stable emulsions from immiscible liquids. The table below compares their key differences.

Comparison	Agitator Mixing Tank	Emulsifying Mixer
Main function	Blending and circulation	High-shear emulsification and homogenization
Shear level	Low to medium	High, rotor-stator at 3,000 rpm
Suitable products	Liquids and blended products, shampoo, syrup, detergent	Creams, emulsions and fine dispersions
Droplet reduction	Limited, >50 μm	Strong, 2–10 μm
Vacuum option	Optional	Commonly integrated
Typical applications	Shampoo, syrup, detergent	Cream, lotion, mayonnaise, ointment

Choose an agitator mixing tank when objective is blending, dissolving or maintaining uniformity. Choose an emulsifying mixer, like a Vacuum Emulsifying Mixer or High Shear Mixer, when product requires fine droplet reduction, strong dispersion or stable oil-water emulsion. King-Pack offers both lines so the upstream tank matches downstream filling.

Mixing can combine liquids, dissolve powders like sugar or salt, or keep solids suspended like spices or TiO2. Optional systems provide heating, cooling, vacuum and automatic control via PLC.

A standard agitated mixing tank is mainly used for blending and circulation. Products requiring intense particle reduction or stable emulsification — such as cream, lotion, mayonnaise — may need a high shear mixer or vacuum emulsifying mixer. Using the wrong tool either damages the product or fails to create a stable emulsion.

How Does an Agitator Mixing Tank Work?

Typical process in an industrial mixing tank:

Raw Material Feeding → Agitator Start-Up → Bulk Material Circulation → Ingredient Blending or Dissolution → Heating or Cooling if Required → Quality Inspection → Discharge or Transfer

The motor rotates the agitator shaft through a gear reducer. The impeller generates flow patterns based on its design. Baffles may be used to reduce vortex formation and improve top-to-bottom mixing, especially with low-viscosity liquids.

Mixing speed and time depend on viscosity, tank size and product requirements. For example, a 1,000 L liquid mixing tank with 5,000 cP syrup may run at 60 rpm for 15 minutes, while a 500 L sanitary mixing tank with 50,000 cP gel needs an anchor agitator at 20 rpm for 40 minutes.

For food plants, heating is often via jacket with hot water at 85°C; cooling via chilled water at 7°C. Temperature sensors ensure the batch never exceeds the heat sensitivity limit.

Types of Agitators for Mixing Tanks

Choosing agitator type is the most important decision for an industrial agitator tank. Multiple agitators may be combined in one tank, for example anchor plus high-speed disperser, depending on process.

Propeller Agitator

Suitable for low-viscosity liquids below 2,000 cP, rapid circulation, liquid-to-liquid blending. Used for beverages and cleaning liquids, water-like chemical blending.

Paddle Agitator

Suitable for gentle mixing, medium-viscosity products up to 10,000 cP, products requiring limited shear such as fragrances added to shampoo.

Turbine Agitator

Suitable for liquid blending, solid suspension, gas-liquid dispersion, processes requiring stronger turbulence. Generates both radial and axial flow.

Anchor Agitator

Suitable for creams, sauces, gels, medium- and high-viscosity products 10,000–80,000 cP. Scrapes near wall, prevents dead zones.

Frame Agitator

Suitable for thick liquids, pastes, products requiring full-tank circulation. Larger diameter than paddle, better turnover for 50,000–150,000 cP.

Scraper Agitator

Suitable for products that stick to the tank wall, heated creams and sauces, high-viscosity materials. PTFE scrapers maintain contact during heating.

Agitator Type	Suitable Viscosity	Typical Application	Main Function
Propeller Agitator	<2,000 cP	Beverage blending, CIP solution, thin solvents	High-speed axial circulation
Paddle Agitator	1,000–15,000 cP	Syrup mixing, light lotion, flavor blending	Gentle bulk blending
Turbine Agitator	1,000–20,000 cP	Solid suspension, neutralization, chemical blending	Turbulent mixing and dispersion
Anchor Agitator	10,000–80,000 cP	Sauce, cream base, gel	Wall scraping and full turnover
Frame Agitator	20,000–150,000 cP	Paste, thick detergent, ketchup base	Full-tank circulation
Scraper Agitator	30,000–200,000 cP	Heated sauce, cosmetic cream, caramel	Prevents burning and wall buildup

For mixing vessel with agitator designs, anchor plus disperser combination is common when you need both viscosity handling and powder wetting.

Mixing Tank Bottom and Vessel Design

Tank geometry affects drainage, cleaning, and mixing efficiency.

Flat Bottom

Simple structure, suitable for general liquid blending, economical configuration. Harder to drain fully.

Sloped Bottom

Improves drainage, guides product toward discharge valve, reduces residue to <0.5%.

Cone Bottom

Suitable for complete discharge, useful for products containing solids or sediment like dressings with herbs.

Dished Bottom

Supports smooth circulation, reduces material accumulation in corners, suitable for sanitary applications and CIP. Most sanitary mixing tank designs use 2B or electropolished interior Ra<0.8 μm.

Stainless Steel Mixing Tank Materials

Commonly available options for stainless steel mixing tank construction:

SS304

Suitable for many general food, beverage, cosmetic and industrial liquid applications. Cost-effective, good corrosion resistance for neutral pH products.

SS316L

Suitable when greater corrosion resistance or stricter hygienic requirements are needed, such as salty sauces, acidic dressings, chloride-containing detergents.

Material selection depends on product composition, acidity, salt content, cleaning chemicals, production standards, and corrosion risk. For pH <4 or chloride >200 ppm, SS316L is recommended. For more information on stainless steel grades, refer to the British Stainless Steel Association.

Applications of Agitator Mixing Tanks

Food and Beverage

Examples: sauces, syrups, marinades, dressings, beverages, dairy products, liquid seasonings. A jacketed mixing tank with scraper agitator handles tomato sauce at 30,000–60,000 cP.

Cosmetics and Personal Care

Examples: shampoo, conditioner, liquid soap, lotion, gel, cleanser. Requires foam control and often vacuum to avoid bubbles.

Pharmaceutical Products

Examples: syrups, liquid preparations, suspensions, gels, cleaning solutions. Needs 316L and documentation for GMP.

Chemical Products

Examples: detergents, lubricants, paints, coatings, solvents, fertilizers, industrial chemicals. May need explosion-proof motors and ATEX rating.

Agitator Mixing Tank vs Emulsifying Mixer

The main difference is the type of mixing each machine performs. An agitator mixing tank is designed for blending, dissolving, and maintaining product uniformity, while an emulsifying mixer uses high shear to create stable emulsions from immiscible liquids. The table below compares their key differences.

Comparison	Agitator Mixing Tank	Emulsifying Mixer
Main function	Blending and circulation	High-shear emulsification and homogenization
Shear level	Low to medium	High, rotor-stator at 3,000 rpm
Suitable products	Liquids and blended products, shampoo, syrup, detergent	Creams, emulsions and fine dispersions
Droplet reduction	Limited, >50 μm	Strong, 2–10 μm
Vacuum option	Optional	Commonly integrated
Typical applications	Shampoo, syrup, detergent	Cream, lotion, mayonnaise, ointment

Choose an agitator mixing tank when objective is blending, dissolving or maintaining uniformity. Choose an emulsifying mixer, like a Vacuum Emulsifying Mixer or High Shear Mixer, when product requires fine droplet reduction, strong dispersion or stable oil-water emulsion. King-Pack offers both lines so the upstream tank matches downstream filling.

Frequently Asked Questions

Q1: What is an agitator mixing tank?

An agitator mixing tank is a stainless steel vessel with a motor-driven impeller that blends liquids, dissolves powders, and keeps solids suspended. It is a core type of industrial mixing tank used before filling.

Q2: What is the difference between an agitator and a mixer?

Agitator refers to the impeller inside the tank; mixer refers to the whole system including tank, motor, and controls. All agitator tanks are mixers, but not all mixers are agitator tanks.

Q3: Which agitator is suitable for high-viscosity products?

Anchor, frame, or scraper agitator with large gearbox and low rpm. For >80,000 cP, scraper with PTFE blades prevents wall burning.

Q4: Can a mixing tank heat and cool the product?

Yes. A jacketed mixing tank provides steam, hot water, or electric heating and chilled water cooling with PID temperature control.

Q5: What is the difference between a mixing tank and an emulsifying tank?

Mixing tank does bulk blending with low shear. Emulsifying tank uses high-shear rotor-stator to reduce droplets to 2–10 microns for stable emulsions.

Q6: Should I choose SS304 or SS316L?

Choose SS304 for neutral pH products. Choose SS316L for acidic, salty, or chloride-containing products and for pharma/cosmetics needing higher corrosion resistance.

Q7: How do I choose the correct mixing tank capacity?

Base it on working volume at 70–80% fill, batches per day, and growth plan. For 2,000 L/day with 500 L batches, a 600–700 L total volume tank gives headspace.

Q8: Can powders be added directly into a mixing tank?

Yes if equipped with disperser or high-shear head, but add slowly to avoid lumps. Pre-mixing in a small powder hopper is better for >5% solids.

Q9: Can an agitator mixing tank connect directly to a filling machine?

Yes. Via sanitary lobe pump and pipeline to an automatic filling machine. Include slow agitation in buffer tank to prevent settling before the filler.

Q10: Can the entry mixers tank be customized for CIP cleaning?

Yes. Options include spray ball, CIP return line, sanitary design with Ra<0.8 μm, and full drainability.
