Hanuo FM100 Standalone Flake Ice Machine

Overview

The Hanuo FM100 Standalone Flake Ice Machine is an air-cooled, self-contained laboratory and light-industrial ice generation system engineered for consistent production of irregular, low-density flake ice. Unlike cubed or nugget ice machines, the FM100 employs a dual-screw extrusion mechanism—where refrigerated stainless-steel barrels compress and shear water into thin, porous flakes under controlled thermal and mechanical stress. This process yields ice with high surface-area-to-volume ratio, rapid thermal transfer kinetics, and minimal meltwater retention—critical attributes for biological sample chilling, histology specimen preparation, cold-chain staging in QC labs, and temperature-sensitive reagent handling. The unit operates autonomously without external condenser water circuits or glycol loops, making it suitable for installation in standard laboratory utility spaces with adequate ventilation and 230 V / 50 Hz single-phase power.

Key Features

• Stainless steel 304 construction throughout ice-making chamber, auger housing, and storage bin—ensuring corrosion resistance, cleanability, and compliance with ISO 8573-1 (compressed air purity) and FDA-recommended food-contact surfaces.
• Dual-screw extrusion system with precision-machined helical augers and thermally stabilized barrel—enabling uniform flake morphology, reduced mechanical wear, and stable output across ambient temperatures up to 32°C.
• Integrated air-cooled condensing unit with high-efficiency rotary compressor and microchannel heat exchanger—eliminating dependency on facility cooling water and reducing total cost of ownership in non-industrial settings.
• Intelligent control board with real-time monitoring of evaporator temperature, compressor duty cycle, and ice thickness feedback—supporting automatic defrost initiation and adaptive run-time optimization.
• Front-access service panel and tool-free bin removal—facilitating routine sanitation per GLP-aligned cleaning SOPs and minimizing downtime during scheduled maintenance.

Sample Compatibility & Compliance

The FM100 generates flake ice with particle dimensions ranging from 1–3 mm in thickness and irregular lateral geometry (typical surface area ≈ 1,200–1,800 cm²/g), ideal for conformal contact with irregularly shaped samples such as tissue blocks, centrifuge tubes, PCR plates, and chromatography columns. Its design conforms to IEC 61000-6-3 (EMC emission limits) and IEC 60335-1 (general safety requirements for household and similar electrical appliances). While not certified for medical device manufacturing (ISO 13485), the unit meets baseline hygiene requirements referenced in USP environmental controls for compounding pharmacies and CLSI GP35-A4 guidelines for cold storage integrity in clinical laboratories.

Software & Data Management

The FM100 operates via embedded firmware without external software dependency. All operational parameters—including cumulative runtime, compressor cycles, and manual defrost logs—are stored in non-volatile memory with timestamping. Optional RS-485 Modbus RTU interface (available upon request) enables integration into BMS platforms or centralized lab infrastructure monitoring systems. Audit trail functionality supports basic GLP documentation needs, including operator-initiated status changes and fault event logging—though full 21 CFR Part 11 compliance requires third-party validation and supplementary electronic signature protocols.

Applications

• Pre-analytical sample stabilization: Maintaining ≤4°C core temperature during blood fractionation, urine sediment processing, and nucleic acid extraction workflows.
• Histopathology support: Rapid chilling of tissue specimens pre-embedding and cooling microtome stages during cryosectioning.
• Pharmaceutical QC: Cold holding of reference standards, dissolution media, and stability test samples prior to analysis.
• Food safety labs: Temperature-controlled transport of swab samples and enrichment broths between collection and plating stages.
• Educational laboratories: Demonstrating phase-change thermodynamics, heat transfer coefficients, and refrigeration cycle fundamentals.

FAQ

What is the recommended water quality for optimal flake ice formation?
Deionized or softened water (hardness < 1.0 gpg, TDS < 50 ppm) is strongly advised to prevent scale accumulation on evaporator surfaces and maintain long-term auger alignment accuracy.
Can the FM100 be installed in an enclosed cabinet or under a bench?
No—minimum 150 mm clearance on all sides and unobstructed airflow above the condenser grille are required to sustain rated capacity and avoid thermal shutdown.
Is the ice output suitable for direct food contact applications?
Yes, when operated with potable water meeting local regulatory standards (e.g., EPA 600/R-95/177) and maintained per manufacturer’s sanitation schedule, the ice complies with FDA 21 CFR 120.8 and EC No. 178/2002 general food safety principles.
Does the unit include a built-in water pump or require pressurized feed?
It requires continuous municipal or reservoir-fed water supply at 0.1–0.4 MPa pressure; no internal pump is integrated.
How often does the condenser coil require cleaning in typical lab environments?
Every 3–6 months under standard ambient dust conditions; more frequent inspection is advised if installed near fume hoods or powder-handling stations.
