Industry-Verified Manufacturing Data (2026)

Stainless Steel Washing Tank

Based on aggregated insights from multiple verified factory profiles within the CNFX directory, the standard Stainless Steel Washing Tank used in the Food Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical Stainless Steel Washing Tank is characterized by the integration of Tank Body and Drain Valve. In industrial production environments, manufacturers listed on CNFX commonly emphasize Austenitic Stainless Steel (e.g., AISI 304, 316L) construction to support stable, high-cycle operation across diverse manufacturing scenarios.

Technical details and manufacturing context for Stainless Steel Washing Tank

Definition
A stainless steel washing tank serves as the core cleaning chamber in an industrial ultrasonic vegetable washer. It holds the water-based cleaning solution and the vegetables to be processed. Ultrasonic transducers, typically mounted to the tank's exterior bottom or sides, generate high-frequency sound waves that create microscopic cavitation bubbles within the solution. These imploding bubbles provide a thorough, non-abrasive scrubbing action that removes soil, pesticides, and microorganisms from the vegetable surfaces. The tank's design is critical for efficient energy transfer, solution circulation, and easy loading/unloading of produce.
Working Principle
The tank contains a liquid medium (typically water with optional detergents). Ultrasonic energy is transmitted through the tank walls into this medium, creating alternating high-pressure and low-pressure waves. During low-pressure cycles, microscopic vacuum bubbles form (cavitation). These bubbles rapidly collapse during high-pressure cycles, releasing intense localized energy that dislodges contaminants from vegetables submerged in the tank.
Common Materials
Austenitic Stainless Steel (e.g., AISI 304, 316L)
Technical Parameters
  • Internal dimensions (Length × Width × Depth) defining the processing volume capacity. (mm) Customizable
Components / BOM
  • Tank Body
    Primary structure containing the cleaning solution and produce. Designed for structural integrity and efficient ultrasonic transmission.
    Material: Stainless Steel
  • Drain Valve
    Allows for controlled emptying of the used cleaning solution from the tank.
    Material: Stainless Steel or Brass
  • Overflow Weir/Drain
    Manages fluid level and prevents overflow, often connected to a filtration or recirculation system.
    Material: Stainless Steel
  • Mounting Flanges/Brackets
    Secure the tank to the washer's frame and provide attachment points for ultrasonic transducers.
    Material: Stainless Steel
Engineering Reasoning
0.1-0.5 MPa (1-5 bar) internal pressure, 20-60°C fluid temperature, 40-100 kHz ultrasonic frequency
Yield strength of 316L stainless steel (205 MPa) exceeded at stress concentration points, cavitation bubble collapse pressure exceeding 1000 MPa at surface, chloride concentration >25 ppm at 60°C
Design Rationale: Stress corrosion cracking from chloride ions at grain boundaries, ultrasonic cavitation erosion from bubble collapse microjets exceeding material hardness (1500 HV), thermal fatigue from cyclic heating (ΔT>30°C) during ultrasonic operation
Risk Mitigation (FMEA)
Trigger Chloride ion concentration exceeding 25 ppm in wash water at temperatures above 50°C
Mode: Intergranular stress corrosion cracking initiating at weld heat-affected zones
Strategy: Implement 316L stainless steel with <0.03% carbon content, post-weld solution annealing at 1050°C followed by rapid quenching
Trigger Ultrasonic transducer power density exceeding 2 W/cm² at tank surface
Mode: Cavitation erosion creating surface pitting exceeding 0.1 mm depth per 1000 operating hours
Strategy: Apply HVOF-sprayed WC-12Co coating (1200 HV hardness) to interior surfaces exposed to direct ultrasonic energy

Application Fit & Sizing Matrix

Operational Limits
pressure: Atmospheric to 0.5 bar gauge (typical), 2 bar maximum design pressure
flow rate: 0-50 L/min (recirculation), 0-200 L/min (drain/fill)
temperature: 5°C to 80°C (operating), -20°C to 120°C (material limits)
slurry concentration: Up to 15% solids by weight (typical), 25% maximum with agitation
Media Compatibility
✓ Fresh produce wash water with mild detergents ✓ Food-grade acidic cleaning solutions (pH 3-8) ✓ Salt brine solutions for vegetable processing
Unsuitable: Chloride concentrations above 500 ppm at elevated temperatures (>60°C) due to risk of stress corrosion cracking
Sizing Data Required
  • Maximum batch volume (L) of produce to be processed
  • Required ultrasonic power density (W/L) for effective cavitation
  • Available footprint dimensions (L x W x H) for installation

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Pitting corrosion
Cause: Chloride ion exposure from cleaning agents or water sources, leading to localized breakdown of the passive oxide layer on stainless steel surfaces.
Stress corrosion cracking
Cause: Combination of tensile stress (from welding, fabrication, or operational loads) and corrosive environment (particularly chlorides), causing crack propagation in susceptible stainless steel grades.
Maintenance Indicators
  • Visible reddish-brown staining or rust spots on stainless steel surfaces, indicating active corrosion
  • Audible hissing or bubbling sounds from tank walls or seams, suggesting leaks or pressure-related failures
Engineering Tips
  • Implement regular water quality monitoring and control chloride concentration below 25 ppm, using deionized or softened water when possible
  • Apply post-weld heat treatment or passivation after any repairs to restore the protective oxide layer and reduce residual stresses

Compliance & Manufacturing Standards

Reference Standards
ISO 9001:2015 Quality Management Systems ASTM A240/A240M Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications CE Marking (EU Regulation 305/2011 Construction Products Regulation for relevant components)
Manufacturing Precision
  • Wall Thickness: +/- 0.5 mm
  • Surface Flatness: 0.2 mm per meter
Quality Inspection
  • Dye Penetrant Test (PT) for weld seam integrity
  • Passivation Test (ASTM A967) for corrosion resistance
