Shumei KQ-500SW Benchtop Sieve & Die-Specific Ultrasonic Cleaner

Overview

The Shumei KQ-500SW is a benchtop ultrasonic cleaner engineered specifically for the precision cleaning of industrial and laboratory-grade sieves, test sieves, wire mesh screens, stamping dies, and perforated plates. It operates on the principle of high-frequency acoustic cavitation—generating controlled microbubble implosions within the cleaning solution at two selectable frequencies (35 kHz and 53 kHz), enabling optimized energy delivery across diverse pore geometries and contaminant types. Unlike standard ultrasonic cleaners, the KQ-500SW integrates purpose-built mechanical fixtures, programmable multi-stage cycles, and dual-mode operation (degas + sparge) to address the unique challenges of deeply embedded particulates, viscous residues, metal fines, and polymer-based fouling in fine-mesh substrates. Its 16.5 L tank volume accommodates standard ASTM E11 and ISO 3310-1 compliant test sieves up to 300 mm diameter, as well as custom-shaped dies and filtration panels used in food processing, mining, pharmaceutical granulation, and printed circuit board manufacturing.

Key Features

• Two-frequency ultrasonic generation (35 kHz / 53 kHz ±1 kHz) for adaptive cleaning—lower frequency delivers higher cavitation intensity for heavy particulate removal; higher frequency enhances resolution for sub-50 µm apertures.
• Full-range ultrasonic power modulation (0–100%) with real-time digital feedback, ensuring reproducible energy input across batch loads and material sensitivities.
• Precise temperature control (ambient to 80 °C) via integrated 800 W heating element, supporting aqueous and mild solvent-based cleaning protocols compliant with ISO 14001 and OSHA hygiene standards.
• Programmable timer (1–480 minutes) with memory retention for up to 10 user-defined cleaning profiles—ideal for GLP-aligned documentation and repeatable QC workflows.
• Stainless steel tank with epoxy-coated exterior housing, resistant to corrosion from alkaline detergents, citric acid solutions, and ethanol-based rinses.
• Digital touchscreen interface with intuitive navigation, real-time parameter display, and audible end-of-cycle alert.
• Integrated degassing mode reduces dissolved gas content prior to cleaning—critical for achieving uniform cavitation distribution in high-aspect-ratio mesh structures.
• Sparging (air bubbling) function enhances fluid circulation and surface agitation during post-cavitation rinse phases, minimizing redeposition of dislodged contaminants.
• Standard inclusion of adjustable stainless steel support racks and custom-fit mesh holders compatible with round, square, and irregularly contoured sieve frames and die plates.

Sample Compatibility & Compliance

The KQ-500SW is validated for use with ASTM E11, ISO 3310-1, and BS 410 test sieves; stainless steel, brass, and nickel-plated wire mesh filters; hardened steel stamping and punching dies; and polymer-reinforced filtration membranes. Its non-contact cleaning mechanism preserves dimensional integrity and surface finish—no risk of abrasion or mechanical deformation. All electrical components meet IEC 61010-1 safety requirements for laboratory equipment. The unit supports audit-ready operation when paired with external logging software, fulfilling traceability prerequisites under FDA 21 CFR Part 11 for regulated environments where sieve calibration and cleanliness verification are documented per SOP.

Software & Data Management

While the KQ-500SW operates via embedded firmware without cloud connectivity, its touchscreen interface logs operational history—including date/time stamps, cycle parameters (frequency, power %, temp, duration), and fault codes—for manual export via USB snapshot (optional accessory). When deployed in GMP-compliant labs, it interfaces seamlessly with LIMS platforms through RS-232 or optional Ethernet module (KQ-500SW-E), enabling automated capture of cleaning metadata for electronic batch records and preventive maintenance scheduling.

Applications

• Restoration of ASTM-certified particle size analysis sieves after mineral, cement, or pharmaceutical powder testing.
• Cleaning of vibrating screen decks and trommel mesh in aggregate and mining operations.
• Removal of ink residue and dried emulsion from silk-screen printing plates and stencils.
• Pre-sterilization preparation of stainless steel filter housings and capsule filters in bioprocessing suites.
• Maintenance of precision wire EDM electrode guides and laser-cut metal shims in metrology labs.
• Decontamination of food-grade stainless steel strainers and centrifugal basket filters between production runs.

FAQ

What sieve sizes and shapes does the KQ-500SW accommodate?
Standard configurations support 200 mm and 300 mm diameter test sieves (ASTM E11), as well as rectangular trays up to 330 × 330 mm. Custom mounting fixtures are available upon request for irregular or oversized mesh panels.
Is the unit suitable for use with flammable solvents?
No. The KQ-500SW is rated for aqueous and water-miscible cleaning solutions only. Solvent use requires explosion-proof certification not included in this model.
Can the ultrasonic frequency be switched during an active cycle?
Yes—frequency selection (35 kHz or 53 kHz) is fully programmable and may be assigned to distinct stages within a multi-step cleaning protocol.
Does the drain system include a filtration trap?
The standard drain valve is unfiltered; however, an inline 50 µm stainless steel mesh strainer kit is available as an accessory to prevent particulate recirculation.
How is temperature stability maintained during extended cleaning cycles?
A PID-controlled heating system with dual thermal sensors ensures ±1.5 °C accuracy across the full 20–80 °C operating range, even under variable ambient conditions.
