XUEKE IMS-85 Flake Ice Machine

Overview

The XUEKE IMS-85 Flake Ice Machine is a compact, laboratory-grade refrigeration system engineered for consistent, on-demand production of irregular, low-density flake ice—ideal for temperature-sensitive sample handling, biological specimen preservation, chromatography cooling baths, and cold-chain support in analytical workflows. Unlike cubed or nugget ice machines, the IMS-85 utilizes a vertical evaporator drum with controlled water film distribution and rapid surface freezing to generate thin, dry, high-surface-area flakes (typically 1–3 mm in thickness and <10 mm in diameter). This morphology ensures rapid thermal transfer, minimal meltwater generation, and uniform packing around vials, centrifuge tubes, or tissue samples—critical attributes for maintaining sample integrity during preparation, transport, or short-term storage. Designed for continuous unattended operation in ISO Class 7–8 cleanrooms and general-purpose lab environments, the unit complies with IEC 61000-6-3 (EMC emission standards) and meets structural safety requirements per GB 4706.13 (China’s household and similar electrical appliances standard), adapted for institutional use.

Key Features

• Fully automatic microprocessor control with real-time status display (ice level, cycle phase, fault diagnostics)
• High-efficiency, low-GWP refrigerant-compatible rotary compressor (R290 or R600a), optimized for stable operation at ambient temperatures up to 32°C
• Air-cooled condenser with intelligent fan modulation—eliminates need for external water drainage or chiller integration
• Stainless steel ice bin (304 grade) with insulated lid and ergonomic front-access door for hygienic, tool-free ice retrieval
• Self-cleaning cycle activated automatically after each harvest to inhibit biofilm accumulation in the water distribution system
• Low-noise design (<58 dB[A] at 1 m), suitable for placement adjacent to analytical instrumentation or shared lab workspaces

Sample Compatibility & Compliance

The IMS-85 supports routine cold preservation protocols across life science, clinical diagnostics, and materials testing laboratories. Its flake ice is compatible with cryogenic sample staging for PCR setup, histology sectioning, electrophoresis buffer cooling, and reagent pre-chilling prior to HPLC or mass spectrometry analysis. While not certified under FDA 21 CFR Part 11 or ISO 13485 as a medical device, the unit adheres to general laboratory equipment hygiene principles outlined in CLSI GP26-A3 and supports GLP-compliant documentation when paired with external loggers (e.g., calibrated thermistors placed within ice loads). All wetted components comply with NSF/ANSI Standard 12 for food equipment—ensuring material safety for incidental contact with biological samples.

Software & Data Management

The IMS-85 operates via embedded firmware without cloud connectivity or proprietary software dependencies. Cycle logs—including start time, harvest duration, and cumulative ice output—are stored locally in non-volatile memory for up to 30 days and accessible via front-panel navigation. Optional RS-485 Modbus RTU interface (available on request) enables integration into building management systems (BMS) or centralized lab monitoring platforms for remote status polling and alarm relay (e.g., high-temperature shutdown, low-water cutoff). Audit trails meet basic GLP record-keeping expectations when exported manually via USB data dump (firmware v2.1+).

Applications

• Cold chain maintenance during sample transit between collection points and analytical labs
• Temperature stabilization of enzymatic assays and protein purification buffers
• Pre-cooling of NMR probe inserts and XRD sample holders
• Support for ASTM D4006 (crude oil water content) and USP <797> compounding environment controls
• Backup cooling for refrigerated centrifuges or low-temperature incubators during maintenance windows

FAQ

What type of refrigerant does the IMS-85 use?
The unit is configured for R290 (propane) or R600a (isobutane) refrigerants—both natural, low-global-warming-potential alternatives compliant with EU F-Gas Regulation No. 517/2014 Annex III and China’s HCFC Phase-out Management Plan.
Is potable water required for operation?
Yes. The IMS-85 requires feed water meeting WHO Guidelines for Drinking-water Quality (2022) or local municipal potable standards. Reverse osmosis or deionized water is not recommended due to insufficient mineral content for optimal ice adhesion and evaporator film formation.
Can the IMS-85 be installed under a benchtop?
No. Minimum clearance of 150 mm must be maintained above and behind the unit for unrestricted airflow across the air-cooled condenser. Wall-mounting or recessed cabinetry is not supported.
Does it support continuous ice dispensing?
The IMS-85 features batch-mode harvesting only—ice is accumulated in the bin and dispensed manually. It does not include auger-based or gravity-fed dispensing mechanisms.
What maintenance intervals are recommended?
Daily visual inspection of water inlet filter; quarterly descaling using citric acid solution (0.5% w/v); annual compressor oil and refrigerant charge verification by authorized service technician.
