Single Layer Agitator Tank for Sale: Key Specs to Compare

When sourcing a single-layer agitator tank for sale, understanding the technical specifications that directly affect performance, product quality and compliance is essential. This article summarizes the most important specs to compare — construction material (notably stainless steel mixing tank grades), agitator design, sealing and cover options, scrapers, mixing frame configuration, capacity and process compatibility — so purchasing teams can evaluate alternatives quickly and confidently for cosmetics, pharmaceuticals, food and chemical production.

Understanding the Product: What a Single Layer Agitator Tank Is

Product overview

Yuanyang single-layer agitator tank is a mixing tank with agitator paddles, mainly applied for liquid materials mixing and blending, which is widely used to manufacture low-viscosity liquids and prepare for cosmetics, pharmaceuticals, chemicals, and food industries.

Features:

⦁ Half-open cover;

⦁ Frame mixing with PTFE scrapers

⦁ Suitable for products of low viscosity liquid products;

Why stainless steel mixing tank construction matters

Most production environments require equipment made of corrosion-resistant alloys. A stainless steel mixing tank provides hygienic surfaces, chemical resistance and durability. Common grades like 304 and 316L differ in corrosion resistance — 316L is preferred for aggressive chemistries and pharmaceutical applications. For background on stainless steel properties, see the overview on Wikipedia.

Key Technical Specs to Compare

Material grade and internal finish

Compare the tank shell and internal finish: 304 vs 316L, surface roughness (Ra). For food and pharma, an internal finish of Ra ≤ 0.8 μm is typical; pharmaceutical or sterile applications may demand Ra ≤ 0.4 μm and electropolished surfaces. Material selection impacts cleanability, product compatibility and lifecycle cost.

Agitator type and power

Single layer agitator tanks often use frame-style paddle agitators for low-viscosity liquids. Key specs: agitator geometry (paddle, propeller, anchor), rotational speed (RPM), power (kW), and tip speed. These determine mixing time, shear, and vortex formation. For emulsions or shear-sensitive products, choose an agitator with appropriate blade profile and variable speed drive.

Scrapers, sealing and cover

PTFE scrapers mounted on a frame maintain a clean jacket-free wall for single-layer tanks. Scraper material and mounting influence heat transfer (if jacketed) and product loss. Sealing options (mechanical seals, lip seals, magnetic drives) are crucial for preventing leaks and contamination; for sanitary markets, comply with standards such as EHEDG or 3-A. For industry guidance, see EHEDG and 3-A Sanitary Standards.

Comparative Table: How Single-Layer Agitator Tanks Stack Up

The table below compares typical specifications buyers should review when evaluating a stainless steel mixing tank for low-viscosity liquid production.

How to interpret the table

Use the comparison to decide whether a single-layer stainless steel mixing tank meets your process needs or whether thermal control (jacketed tanks) or heavier duty mixing is required. If your product requires heating/cooling within the vessel, a jacketed design might be the right choice; for straightforward blending of low-viscosity liquids, the single-layer agitator tank is often more cost-effective and easier to clean.

Process Compatibility and Regulatory Considerations

Applications: cosmetics, pharma, food, chemicals

Single-layer agitator tanks are optimised for low-viscosity liquids: lotions, toners, syrups, liquid soaps, and many chemistry intermediates. For pharmaceuticals and food products, prioritize sanitary design: smooth welds, drainability, CIP (clean-in-place) capability and compliant seals. Regulatory standards and best practices can be reviewed through authoritative bodies such as U.S. FDA and WHO when applicable.

Sanitation and cleaning (CIP/SIP)

Assess whether the single-layer tank supports CIP or requires manual cleaning. The tank geometry, nozzle placement, and internal finish determine cleanability. PTFE scrapers reduce residue on sidewalls for products that settle or stick. For validation, you may need to run swab tests and conductivity or TOC measurements after cleaning cycles.

Documentation and compliance

Request documentation from suppliers: material certificates (EN/ASTM), surface finish reports, test records, and welding procedures (WPS/PQR). For pharmaceutical buyers, ask for IQ/OQ/PQ protocols. These documents establish equipment traceability and compliance during audits.

Installation, Operation, and Maintenance Best Practices

Site requirements and installation

Plan for adequate floor loading, foundation, and access for maintenance. Single-layer tanks are lighter than jacketed equivalents but still require level supports and secure anchoring to prevent vibration. Ensure sufficient headroom for half-open covers and agitator drive maintenance.

Operation tips for optimal mixing

Start with recommended fill levels (often 30–80% of tank volume depending on agitator type) to ensure proper vortex and mixing efficiency. Adjust agitator speed to balance mixing time and shear: higher RPM reduces mixing time but increases shear and possibly foaming. Use sampling ports for in-process checks.

Maintenance schedule

Regularly inspect seals, bearings and scrapers. PTFE scrapers wear over time and should be replaced before they damage the inner surface. Lubricate gearbox and verify motor alignment. Keep a log of maintenance activities to support lifecycle management.

FAQ — Common Questions About Single Layer Agitator Tanks

Q: Is a single-layer agitator tank suitable for heating or cooling products?

A: Single-layer tanks do not include an integrated jacket, so they are not ideal when precise heating or cooling inside the vessel is required. You can use external heat exchangers or inline heaters/coolers with circulation loops. For processes needing precise thermal control, consider a jacketed tank.

Q: What product viscosities are appropriate for this tank?

A: The Yuanyang single-layer agitator tank is optimized for low-viscosity liquids — from water-like fluids up to light syrups and lotions. Higher viscosities require specialized agitators (anchors, high-torque drives) or different tank designs.

Q: How do PTFE scrapers affect cleaning and product waste?

A: PTFE scrapers maintain a thin film of product on the walls and reduce accumulation, improving drainability and reducing product waste. They also simplify cleaning cycles by minimizing deposit formation on the inner surface.

Q: What certifications should I ask from a supplier?

A: Request material certificates (EN/ASTM), surface roughness test reports, welding procedure documents, and for regulated industries, IQ/OQ/PQ protocols. If applicable, confirm adherence to hygienic design standards from organizations like EHEDG or 3-A Sanitary Standards.

Q: Can this tank be used for pharmaceutical production?

A: Yes — when specified with 316L stainless steel, appropriate surface finish (Ra ≤ 0.4 μm when required), sanitary seals and documented validation support. Discuss required documentation and cleanability validation with the supplier to meet GMP requirements.
