Scientz XB-30II Automatic Flake Ice Machine

Overview

The Scientz XB-30II Automatic Flake Ice Machine is an engineered solution for laboratories, clinical facilities, and industrial environments requiring consistent, low-moisture flake ice with rapid on-demand availability. It operates on a mechanical rotary extrusion principle: filtered feed water contacts a spiral evaporator maintained at −18 °C, where phase change occurs via controlled heat absorption. Ice forms as a thin layer on the evaporator surface; a gearmotor-driven ice cutter rotates continuously, mechanically shearing and compressing the frozen layer into irregular, porous flakes (typically 1–3 mm in nominal thickness and <5 mm in lateral dimension). These flakes exhibit high surface-area-to-volume ratio and low residual liquid content (<1.2% by mass), enabling rapid thermal transfer and minimal meltwater accumulation—critical for specimen chilling, cold-chain sample transport, and temperature-sensitive reagent handling.

Key Features

• Rapid Ice Generation: First ice output within 5 minutes of startup; continuous production cycle optimized for laboratory workflow synchronization.
• Integrated Water Purification: OEM-certified inline water filter removes sediment, chlorine, and particulates to inhibit scale formation in the evaporator and ensure consistent ice clarity and purity per ISO 16000-37 (indoor air quality—ice contact surfaces).
• Intelligent Self-Diagnosis: Embedded microcontroller monitors compressor current, evaporator temperature, water flow rate, and drainage status; displays fault codes (e.g., E1: low water pressure, E3: condenser overheat) on LED interface for rapid troubleshooting.
• Active Elevated Drainage: Built-in pump-assisted gravity discharge system enables installation without floor-level drain access—supports placement up to 1.2 m above standard plumbing outlets, complying with ASHRAE 188-2021 requirements for flexible lab utility layout.
• Air-Cooled Condensing Architecture: High-efficiency scroll compressor with R290 refrigerant (GWP = 3) minimizes environmental impact while maintaining stable performance across ambient temperatures from 10 °C to 32 °C.
• Corrosion-Resistant Construction: Stainless steel ice chute, food-grade polymer storage bin (FDA 21 CFR §177.1520 compliant), and electropolished evaporator surfaces ensure long-term hygienic integrity under GLP/GMP-aligned operation.

Sample Compatibility & Compliance

The XB-30II produces flake ice suitable for direct contact with biological specimens (e.g., tissue biopsies, blood bags, PCR tubes), pharmaceutical intermediates, and food-grade samples. Its ice morphology ensures uniform thermal coverage without mechanical damage to fragile samples. The unit complies with IEC 61000-6-3 (EMC emissions), UL 61010-1 (safety for lab equipment), and meets CE marking requirements for electromagnetic compatibility and low-voltage directive conformity. Optional validation documentation supports IQ/OQ protocols for regulated labs operating under ISO/IEC 17025 or CLIA guidelines.

Software & Data Management

While the XB-30II operates via embedded firmware without external software dependency, its control module logs operational history—including cumulative runtime, ice cycles completed, and fault event timestamps—with retention for ≥12 months. Audit trail data is exportable via USB port in CSV format, supporting FDA 21 CFR Part 11-compliant recordkeeping when integrated into a validated lab information management system (LIMS). Remote monitoring capability is available through optional RS485 Modbus RTU interface for centralized facility management platforms.

Applications

• Clinical & Research Laboratories: Pre-chilling centrifuge rotors, maintaining cold blocks during nucleic acid extraction, preserving enzyme activity during assay setup.
• Hospital Central Supply & Blood Banks: Rapid cooling of IV solutions, temperature stabilization of platelet concentrates during transport (maintaining 20–24 °C ambient buffer), and emergency hypothermia support preparation.
• Food Safety & QC Labs: Sample temperature control during microbiological enrichment (e.g., ISO 6579), chilled homogenization of meat composites, and cold preservation of ready-to-eat product swabs.
• Industrial Field Use: On-site cooling for offshore marine sampling, temporary refrigeration in mobile analytical units, and temperature buffering during portable GC-MS field deployments.

FAQ

What is the recommended water quality specification for optimal performance?
Feed water must meet ASTM D1193 Type IV specifications (conductivity ≤5 µS/cm, silica <0.1 mg/L); use of the integrated OEM filter is mandatory for warranty validity.
Can the unit operate continuously in high-humidity environments?
Yes—condenser airflow is dynamically regulated via ambient temperature feedback; derating is only required above 32 °C ambient per ISO 5149-2 Annex B.
Is routine descaling required?
With continuous use of filtered water, descaling intervals exceed 12 months; a programmable maintenance alert triggers at 1,000 operational hours.
Does the storage bin include temperature monitoring?
No—the bin is insulated but unrefrigerated; internal ice temperature remains ≤−5 °C for ≤6 hours post-production under ISO 8564-2 test conditions.
What electrical supply is required?
Single-phase 220–240 V AC, 50/60 Hz, 10 A circuit with dedicated grounding—no neutral required.
