Y90 Fully Automated Video-Based Fat Melting Point Analyzer

Overview

The Y90 Fully Automated Video-Based Fat Melting Point Analyzer is a precision thermal analysis instrument engineered for the objective, reproducible determination of melting behavior in edible fats, oils, waxes, and related lipid-based materials. It operates on the principle of real-time optical monitoring of solid-to-liquid phase transition under controlled heating, using high-resolution digital video capture synchronized with high-fidelity platinum resistance temperature sensing (Pt100). Unlike traditional manual capillary methods reliant on visual endpoint estimation, the Y90 digitizes the entire melt progression—capturing meniscus movement, shrinkage, collapse, and complete liquefaction—and applies algorithmic threshold detection to define the onset, clear point, and midpoint temperatures per ASTM D3418 and ISO 637:2022 conventions. Its integrated water-bath heating system—constructed with borosilicate glass tubing to prevent scale formation and corrosion—ensures uniform thermal distribution and minimal thermal lag across the sample zone. The instrument is designed for compliance-driven laboratories requiring traceable, auditable, and operator-independent results in food quality control, R&D, and regulatory submission contexts.

Key Features

• Fully automated melting point detection via synchronized HD video imaging and Pt100 temperature logging—eliminates subjective visual interpretation and inter-operator variability.
• Dual-sample capacity with independent capillary positioning, enabling comparative analysis or parallel validation runs without sequential delay.
• Programmable heating profiles: 40 pre-stored experimental protocols, each supporting up to five discrete temperature segments (e.g., hold → ramp → dwell), configurable via intuitive touchscreen interface.
• High-stability water bath with rapid thermal response (<5 s settling time after setpoint change) and precise rate control from 0.1 to 10 °C/min (±0.05 °C/min linearity).
• TFT true-color display (7-inch, 800 × 480) with real-time video feed, temperature curve overlay, and live parameter status—operable without external PC connection.
• Onboard data storage: 16 GB internal flash memory + SD card slot; supports full-session video recording (H.264), timestamped metadata, and automatic overwrite warnings when capacity reaches 90%.
• Comprehensive connectivity: USB 2.0 host/device, RS-232 serial, and 10/100 Mbps Ethernet—enabling integration into LIMS, remote monitoring, and secure data export in CSV, PDF, and XML formats.

Sample Compatibility & Compliance

The Y90 accommodates standard dual-open capillaries (OD 4 mm, ID 1.0 mm, length 100 mm), compatible with common fat preparation techniques including packing, sealing, and solvent-free loading. It supports semi-solid and low-viscosity lipid matrices—including cocoa butter, palm oil fractions, lard, hydrogenated vegetable oils, and cosmetic waxes—without modification. The system complies with multiple national and international standards governing fat characterization: SNT 0801.5–1999 (China Customs inspection method), GB/T 24892–2010 (determination of slip melting point of fats and oils), and GB/T 12766–2008 (melting point of edible oils). Its architecture supports GLP/GMP-aligned workflows, including 200-user role-based access control, electronic signature support, audit trail logging (per FDA 21 CFR Part 11 requirements), and full traceability of calibration history, method versioning, and raw video archives.

Software & Data Management

The proprietary Y90 Control Suite (v3.2+) provides full instrument orchestration, video analytics, and report generation. It features intelligent melt recognition algorithms trained on >10,000 reference lipid transitions, capable of distinguishing between polymorphic melt steps (e.g., β’ → β transitions in cocoa butter) and identifying partial melting artifacts. All experimental sessions are automatically archived with embedded calibration certificates, environmental logs (ambient temp/humidity), and user authentication stamps. Reports conform to ISO/IEC 17025 documentation standards and include customizable templates compliant with AOAC, Codex Alimentarius, and internal QA SOPs. Data export supports both human-readable PDFs (with embedded video thumbnails) and machine-readable CSV files containing second-by-second temperature/video frame index pairs—ideal for statistical process control (SPC) and multivariate trend analysis.

Applications

• Quality assurance of refined and specialty fats in edible oil refineries and confectionery manufacturing.
• Polymorph screening and crystallization kinetics studies during fat reformulation (e.g., trans-free margarine development).
• Stability assessment of lipid-based pharmaceutical excipients (e.g., glycerol monostearate, stearic acid in suppositories).
• Regulatory testing for import/export clearance under Chinese AQSIQ, EU Regulation (EC) No 1528/2007, and US FDA food additive provisions.
• Routine QC in dairy fat analysis (butterfat, anhydrous milk fat) per IDF Standard 122A:2019.

FAQ

Does the Y90 require external cooling equipment for rapid cooldown between runs?
No—the system employs forced-air convective cooling with adjustable fan speed, achieving return to 10 °C from 100 °C in ≤12 minutes without cryogenic aids.
Can the video analysis be manually overridden or reprocessed post-acquisition?
Yes. Raw video files (.mp4) and temperature logs (.csv) are stored separately; users may replay, adjust detection thresholds, and recompute melt points using the offline Review Module.
Is calibration traceable to NIST or other national metrology institutes?
The built-in Pt100 sensor is factory-calibrated against a Fluke 724 temperature calibrator (NIST-traceable certificate included); annual recalibration services are available with full uncertainty budget reporting.
What maintenance is required for long-term accuracy?
Biannual verification using certified reference standards (e.g., pure stearic acid, palmitic acid) is recommended; the glass water bath requires only distilled water refills and periodic wipe-down with ethanol—no descaling or lubrication needed.
How does the Y90 handle samples with broad or multi-step melting ranges?
The software identifies up to three distinct thermal events per sample (onset, inflection, clear point) and reports all with individual confidence intervals derived from frame-rate–limited derivative analysis (15 fps video + 0.1 °C resolution).
