Tan Long Factory Standard Technical Specifications Matrix
1. Proprietary Two-Stage Ice Glazing Process
To produce a crystal-clear, durable protective ice glaze, Tan Long ice glazers employ a two-stage process:
• Stage 1 (Bottom Immersion Dip): Frozen products (-18°C) entering the immersion tank encounter +0.5°C purified water, instantly crystallizing an initial thin ice barrier onto the food surface.
• Stage 2 (Multi-Angle Spray Curtain): As products ascend from the bath, overhead high-pressure spray curtains uniformly coat top and recessed contours, sealing all micro-pores.
2. Water Conservation & Recirculation Energy Optimization
Glazing water recirculates continuously through dual coarse and fine stainless filter screens, straining out organic debris prior to returning to the chiller heat exchanger. This saves processing plants up to 70% in daily clean water consumption while maintaining strict export sanitation standards.
3. Easy Sanitary Maintenance & Global Export Compliance
The open structural chassis features zero sanitary dead zones, with electropolished SUS304 surfaces repelling bacterial adhesion. The entire conveyor assembly tilts upward via hydraulic lift hinges for rapid, thorough washdown of the tank bottom between shifts.
Competitive Advantages & Market Comparison Matrix
Technical comparison between genuine Tan Long refrigeration equipment manufactured at Duc Hoa 1 Industrial Park versus substandard market alternatives:
Tan Long Equipment Advantages
- ✓ Dual top-and-bottom spray manifolds paired with bottom immersion tank ensure uniform 360-degree glaze
- ✓ Automated closed-loop filtration maintains glazing water crystal clear and sanitary
- ✓ Directly interfaces with Tan Long sanitary falling film water chillers for +0.5°C water
- ✓ Turnkey Capex is 40% lower than imported Korean/European glazers while matching performance
Drawbacks of Manual / Used Imported Systems
- ✗ Cheap artisanal dip tanks quickly accumulate dirty water and suffer massive glaze thickness variance
- ✗ Impure metals corrode and pit in saline marine environments, failing HACCP hygiene audits
- ✗ Absence of precise water temperature regulation causes lumpy glazes or partial melting
- ✗ Unsealed generic motors short-circuit frequently in high-humidity washdown areas
Frequently Asked Questions (FAQs) by Engineers & Investors
Q1: How is glazing water temperature maintained at a stable +0.5°C?
Tan Long couples the glazer directly with our sanitary falling film water chiller. The chiller continuously pulls recirculating water down to +0.5°C to +1°C without pipe freeze-cracking risks.
Q2: Can Tan Long ice glazing machines adjust glaze ratios for diverse seafood species?
Yes. Operators simply adjust conveyor belt speed via the HMI touchscreen: faster transit yields lighter glaze coats (5% - 8%), while slower speeds produce thicker coatings (15% - 20%). Pressure valves on overhead spray nozzles can also be fine-tuned.
