Field Trial Notes: How Slurry Ice Covers and Chills Live Fish in 32°C Heat
Intro:
This note focuses on what happens when live fish meet slurry ice in a hot working environment. The aim is not a laboratory comparison, but a practical look at coverage speed, chilling evenness, and how the ice behaves over time.
Trial Setup
The trial was carried out in Shenzhen at an ambient temperature of 32°C. A containerized 10-ton slurry ice system from ICESTA was used. The batch included 16 kg of live fish and 32 kg of slurry ice. The measured slurry ice temperature was -1.3°C; with a higher brine concentration, the system can reach around -4°C.
What We Observed
| Checkpoint | Field Note |
|---|
| 2 minutes | Fish surfaces were well covered; the batch began to firm up quickly |
| 2 hours | The slurry ice retained concentration, flowability and wrapping ability |
| Chilling pattern | Coverage appeared even, with fewer cold spots |
| Moisture loss | Less exposed surface, helping reduce moisture loss |
How to Read This Trial
For seafood operations, the value of slurry ice is not only low temperature, but also how completely it contacts the product. Better contact supports more even chilling and less exposed surface. The 2-hour check is useful because it shows whether the ice still flows and wraps after initial use.
Where This Type of System Fits
A containerized slurry ice system can be considered for fishing landing sites, seafood processing lines, cold-chain storage, and temporary or mobile cooling points. Final selection should be based on daily volume, product type, ambient conditions and storage duration.
Equipment Note
The unit used in this trial is an ICESTA containerized 10-ton slurry ice system. The video was recorded on site and shows ice preparation, temperature checking, fish coverage and the ice condition after 2 hours.

FAQ
- Q1: Is slurry ice effective in high ambient temperatures?
A: This trial was conducted at 32°C. The key is whether the system can maintain ice quality and coverage during use; site conditions and system sizing matter. - Q2: Why check both 2 minutes and 2 hours?
A: The 2-minute check shows initial coverage and firming; the 2-hour check shows whether the ice still flows and wraps after use. - Q3: Is the slurry ice temperature fixed?
A: No. In this trial it was -1.3°C. With higher brine concentration, it can reach around -4°C. The right setting depends on the application. - Q4: Who should consider a containerized system?
A: Operators who need a movable or quickly deployable cooling unit, such as landing sites, processing plants and cold-chain points.
