Technical details and manufacturing context for Solution Tank

Definition

The Solution Tank is a critical component of a CIP (Clean-in-Place) Cleaning Module, designed to hold and manage the various chemical solutions (e.g., caustic, acid, sanitizer, rinse water) used in automated cleaning cycles. It typically includes features for solution level monitoring, temperature control, and connection to the CIP supply and return lines. Constructed from stainless steel (commonly 316L for corrosive chemicals), the tank is engineered to withstand specified working pressures and temperatures, with internal surface finishes suitable for hygienic cleaning. The tank's nominal capacity ranges from 500 to 10,000 liters, and its design pressure is 0.2–0.6 MPa. Design temperature spans -10 to 120 °C, accommodating hot water and caustic solutions. Wall thickness varies from 4 to 12 mm, and internal surface roughness is ≤0.8 μm Ra (ISO 4287) to facilitate sanitation. Insulation thickness of 50–100 mm helps maintain solution temperature. Empty weight ranges from 200 to 3000 kg, and overall dimensions (diameter × height) are typically 800–2500 mm × 1500–5000 mm. These values are reference ranges; actual specifications must be confirmed with the manufacturer for the specific model and application. The tank operates by receiving and storing prepared cleaning solutions. During a CIP cycle, a pump draws solution from the tank and circulates it under pressure through process piping and equipment. The solution may be heated within or before entering the tank to enhance cleaning efficacy. After use, the solution is either drained, recovered for reuse, or returned to the tank for subsequent cycles, depending on system design. When selecting a solution tank, verify that the nominal capacity matches the cleaning cycle volume and flow rate, and that the working pressure and temperature ratings align with your process requirements. Confirm material grade (e.g., 316L) for chemical compatibility, and ensure internal surface finish meets hygiene standards. Check that the tank's dimensions and weight fit your installation space and structural support. Always consult the legal manufacturer or supplier to validate model-specific values and standards.

Working Principle

The tank receives and stores a prepared cleaning solution. During a CIP cycle, a pump draws solution from the tank and circulates it under pressure through the process piping and equipment to be cleaned. The solution may be heated within or before entering the tank to enhance cleaning efficacy. After use, the solution is either drained, recovered for reuse, or returned to the tank for subsequent cycles, depending on the system design.

Frequently Asked Questions

What is the typical capacity range for a CIP solution tank?

According to reference data, the nominal capacity ranges from 500 to 10,000 liters. The actual capacity should be selected based on the cleaning cycle volume and flow rate required for your specific process. Always confirm the exact capacity with the manufacturer for your application.

What materials are commonly used for solution tanks?

The material grade on file is Stainless Steel 316L, which is suitable for corrosive chemicals. Other grades like 304 may be available, but the reference data lists 304/316L as a range. Verify the material grade with the supplier to ensure compatibility with your cleaning solutions.

What working pressure and temperature can the tank handle?

The reference working pressure is 0.2–0.6 MPa, and the design temperature range is -10 to 120 °C. These are reference values; the actual ratings depend on the tank's design and construction. Confirm with the manufacturer for your specific model.

How do I ensure the tank meets hygiene requirements?

The internal surface roughness is specified as ≤0.8 μm Ra (ISO 4287), which is suitable for hygienic cleaning. Additionally, the tank may have insulation to maintain temperature. For specific hygiene standards, consult the manufacturer and relevant regulations for your industry.
