Hanuo FM30 Standalone Flake Ice Machine

Overview

The Hanuo FM30 Standalone Flake Ice Machine is an engineered solution for laboratories requiring consistent, hygienic, and on-demand flake ice production. Unlike cubed or nugget ice systems, this unit employs a dual-screw extrusion compression mechanism to produce irregular, thin, and highly surface-area-rich flake ice—ideal for rapid thermal transfer, sample cooling, and biological specimen preservation. The machine operates autonomously with no external chiller or glycol loop required, making it suitable for benchtop or under-counter installation in space-constrained lab environments. Its air-cooled condensing system eliminates the need for dedicated water drainage infrastructure, while the R134a refrigerant ensures compliance with current environmental regulations governing ozone depletion potential (ODP = 0) and global warming potential (GWP) thresholds applicable to laboratory-grade refrigeration equipment.

Key Features

• Full microprocessor-based control system with real-time status monitoring: operational mode, ice-full detection, low-water alarm, and fault diagnostics displayed via LED interface.
• Stainless steel 304 construction throughout the ice-making chamber, auger housing, and exterior cabinet—resistant to corrosion, easy to sanitize, and compliant with ISO 13485-informed cleanroom handling protocols.
• Dual-screw extrusion design ensures uniform ice density and minimal mechanical stress on the ice matrix, reducing melt rate during short-term storage and improving thermal contact efficiency with temperature-sensitive samples.
• Automatic municipal water feed with integrated float valve and anti-dry-run protection—eliminates manual refilling and prevents compressor damage due to insufficient coolant circulation.
• Energy-optimized operation at 300 W nominal power draw; meets IEC 61000-3-2 harmonic current emission standards for laboratory electrical compatibility.

Sample Compatibility & Compliance

The FM30 produces microbiologically inert flake ice suitable for direct contact with non-sterile biological materials—including tissue samples, enzyme solutions, centrifuged pellets, and PCR reagent stocks—provided end-user sterilization protocols (e.g., UV exposure or filtered water supply) are implemented upstream. While the unit itself is not certified as medical device (Class I or II), its stainless steel wetted surfaces and absence of lubricants in the ice path align with general Good Laboratory Practice (GLP) requirements for ancillary cold-chain support equipment. It conforms to CE marking directives for electromagnetic compatibility (EMC) and low-voltage equipment (LVD), and complies with RoHS 2011/65/EU restrictions on hazardous substances.

Software & Data Management

This is a standalone, non-networked appliance with no embedded software stack or data export capability. All operational parameters are managed via front-panel controls and visual indicators only. No firmware updates, remote diagnostics, or audit trail functionality are provided—consistent with ISO/IEC 17025 Annex A.2 guidance that defines “non-measuring support equipment” as exempt from formal calibration or electronic record retention requirements. Users intending integration into 21 CFR Part 11–compliant workflows must implement external logging (e.g., facility SCADA or lab information management system [LIMS] interfaces) for ice production timestamps and maintenance events.

Applications

• Cooling of electrophoresis gels and blotting membranes during transfer procedures.
• Temperature stabilization of enzymatic reaction mixtures prior to incubation or analysis.
• Short-term cryoprotection of freshly isolated primary cells before freezing media addition.
• Chilling of HPLC autosampler trays and GC inlet liners to minimize analyte degradation.
• Supporting histology labs in maintaining optimal sectioning temperatures for frozen tissue blocks.
• Providing rapid, localized cooling for QA/QC sampling in pharmaceutical manufacturing environments where controlled ambient temperature deviation is restricted per USP .

FAQ

Is the FM30 suitable for GMP-regulated cleanrooms?
It can be installed in ISO Class 7 or lower cleanrooms if placed outside the critical processing zone and supplied with filtered potable water; however, it lacks HEPA-filtered air intake or static-dissipative housing required for ISO Class 5 environments.
What maintenance intervals are recommended?
Descale the evaporator plate every 3 months using food-grade citric acid solution; inspect and clean the air intake grille weekly to maintain condenser efficiency.
Can the unit operate continuously without manual intervention?
Yes—once connected to a stable water source and power supply, it cycles automatically between ice production and standby based on bin-level sensor feedback.
Does the machine meet NSF/ANSI Standard 12 for food equipment?
No—this model is designed exclusively for laboratory use and has not undergone NSF certification testing for food contact surfaces or sanitation validation.
What is the expected service life under typical lab usage?
With proper descaling and ambient temperature control (15–32 °C), the compressor and extrusion assembly demonstrate >8,000 operating hours before major component replacement is indicated.
