In industrial manufacturing, mixing efficiency is the foundation of consistent product quality. From blending chemicals to brewing beer, large-scale mixing operations depend heavily on the performance of large tank agitators.

These machines are designed to ensure that every component in a formulation is evenly distributed — resulting in homogeneity, stability, and improved process control.

As a leading stainless steel tank manufacturer, HAISHUN provides custom-engineered large tank agitators for multiple sectors including beer brewing, chemical production, cosmetics, pharmaceuticals, and food & beverage. Each system integrates advanced European and American technology and meets bio-pharmaceutical standards for hygiene and performance.

This article explores how to choose the best large tank agitator, what to look for in design, and how HAISHUN’s technology delivers superior mixing results.

1. Understanding Large Tank Agitators

A large tank agitator is a mechanical device mounted on top or side of a tank to facilitate movement and mixing of liquids, semi-solids, or slurries.
These agitators ensure:

Homogeneous mixing of components

Heat and mass transfer optimization
Elimination of dead zones
Improved reaction speed and product uniformity

They are indispensable in processes like fermentation, emulsification, dissolution, and suspension.

Key Components

1. Motor and Gearbox – Provide rotational force and speed control.

2. Shaft – Transfers torque from the motor to the impeller.

3. Impeller or Blade – Generates flow and turbulence.

4. Seal Assembly – Prevents leakage and contamination.

5. Mounting System – Ensures secure installation and alignment.

2. Factors to Consider When Choosing a Large Tank Agitator

Selecting the right agitator involves understanding your process requirements and the characteristics of your material. Below are the most important parameters to evaluate.

(1) Mixing Purpose and Fluid Type

Different applications require different flow patterns:

Mixing Objective	Recommended Agitator Type	Typical Industry Use
Liquid-liquid blending	Propeller or turbine	Beverage, chemical
Suspension of solids	Pitched blade turbine	Chemical, food
High-viscosity products	Anchor or helical ribbon	Cosmetics, creams
Emulsification	Disperser or high-shear mixer	Pharmaceutical, cosmetics
Fermentation	Paddle or propeller	Brewing, bioprocessing

(2) Tank Volume and Aspect Ratio

Tank geometry (height-to-diameter ratio) affects fluid circulation. HAISHUN’s engineering team adjusts impeller diameter, shaft length, and blade pitch to ensure full mixing coverage.

(3) Material Construction

For industries requiring strict hygiene, SUS304 or SUS316L stainless steel is essential. HAISHUN’s agitators feature:

Smooth polished surfaces (Ra ≤ 0.4 μm)
CIP/SIP cleaning compatibility
FDA and GMP compliance

(4) Drive System and Speed Control

Energy efficiency and torque stability are key in large mixing operations. HAISHUN uses variable frequency drive (VFD) motors and reliable European gear reducers, allowing precise speed adjustment to different viscosities.

(5) Mounting Method

Agitators can be top-mounted, side-mounted, or bottom-mounted, depending on tank design and mixing requirements. HAISHUN’s engineers provide 3D modeling to optimize fluid dynamics before installation.

3. HAISHUN Large Tank Agitator — Technical Specifications

Parameter	Specification Range	Customization Available
Tank Volume	100L – 100,000L	Yes
Material	SUS304 / SUS316L	Yes
Motor Power	0.75kW – 55kW	Yes
Impeller Type	Propeller / Paddle / Anchor / Turbine	Yes
Speed Range	10 – 200 rpm (VFD adjustable)	Yes
Seal Type	Mechanical / Magnetic / Sanitary	Yes
Surface Finish	Mirror polish / matte / custom	Yes
Cleaning	CIP / SIP system integration	Optional

All HAISHUN agitators are manufactured in accordance with bio-pharmaceutical standards to guarantee high hygiene, durability, and consistent performance.

4. Industrial Applications of Large Tank Agitators

(1) Beer Brewing

In beer brewing, agitators maintain even yeast distribution and temperature uniformity during fermentation. HAISHUN’s stainless steel fermenters and agitators ensure smooth oxygen transfer and consistent taste.

(2) Food & Beverage

Used for blending sauces, juices, and dairy products, our agitators ensure homogeneous texture and prevent sedimentation in storage or mixing tanks.

(3) Chemical Manufacturing

HAISHUN agitators provide efficient dispersion for viscous and reactive materials, enabling precise formulation and consistent chemical reactions.

(4) Cosmetic Production

For creams, lotions, and gels, agitators with anchor or helical blades guarantee smooth textures and stable emulsions without trapped air.

(5) Pharmaceutical Industry

In pharmaceutical processing, agitators must meet GMP standards. HAISHUN’s sterile design supports aseptic mixing, ensuring product integrity and contamination prevention.

5. Advantages of Choosing HAISHUN Agitation Systems

(1) Precision Engineering

Every agitator is designed using CFD (Computational Fluid Dynamics) simulation to ensure optimal flow and energy efficiency.

(2) High-Grade Materials

Using SUS316L stainless steel and laser welding technology, HAISHUN guarantees long service life, corrosion resistance, and easy cleaning.

(3) Flexible Customization

HAISHUN provides design flexibility — from lab-scale mixing vessels to 100,000L industrial tanks — all tailored to client specifications.

(4) Hygienic and Easy to Maintain

All agitators are equipped with sanitary mechanical seals and mirror-polished surfaces, reducing contamination risks and simplifying cleaning.

(5) Energy Efficiency and Cost Savings

By optimizing impeller geometry and motor power, HAISHUN agitators achieve up to 15% energy savings compared to conventional models.

6. Maintenance & Safety Guidelines

To ensure long-term performance, proper maintenance is vital:

1. Routine Inspections: Check for wear on seals, bearings, and shafts.

2. Lubrication Schedule: Maintain gearbox lubrication every 2,000 hours.

3. Vibration Monitoring: Identify imbalance or misalignment early.

4. Clean-in-Place (CIP): Run automated cleaning cycles with approved detergents.

5. Use Genuine Parts: HAISHUN-certified components ensure compatibility and safety.

A well-maintained agitator minimizes downtime, reduces energy costs, and enhances batch consistency.

7. Real-World Example — Brewing Application Case

A craft beer producer in Southeast Asia required a high-volume fermentation system with consistent yeast circulation and oxygen control.
HAISHUN supplied a 10,000L stainless steel fermenter with a top-mounted propeller agitator equipped with variable speed control.

Results:

Fermentation time reduced by 15%
Product uniformity improved by 20%
Cleaning time reduced by 30% due to CIP integration

This case demonstrates how HAISHUN’s engineering expertise delivers measurable performance improvements.
