1. Harvest
Live shrimp is uniformly chilled to <0°C in 5 minutes to quickly stop deterioration while also reducing labour and handling.
Shrimp
The Deepchill® Difference
Higher quality, better yield, even more efficient operations – every advantage that you can bring to your business helps enhance your profitability. Deepchill® slurry technology is a highly advanced preservation process that can help you improve your shrimp production and increase the overall profitability of your business.
Fast, uniform superchilling
Cool your product 3 times faster. Shrimp at 24–28ºC can be uniformly superchilled to -1ºC in less than 5 minutes. The shrimp is maintained at an even temperature throughout your entire batch for consistent quality.
Highest quality
Used in either slush or dry form, Deepchill® suspends shrimp and protects it from being squeezed or crushed under pressure. It also preserves the appearance, colour, and firmness, and reduces bacterial growth, resulting in the highest quality head-on shrimp.
Streamlined operation with speed and efficiency
Deepchill® helps you simplify and speed up the shrimp harvesting and processing operation, greatly reducing labour requirements and cutting unnecessary steps such as pre-chilling, chemical treatment, or moving ice in the facility. With less steps in the process and much faster cooling speed, your entire operation benefits from a saving in cost and time.
Less ice consumption
The efficient cooling of Deepchill® lets you cut the ice consumption required at shrimp harvest or processing by 30% or more. It eliminates the need to constantly replenish melted ice or break up clumped ice, saving time and money.

Maintain freshness in the cold chain
Deepchill® fits easily into your operation and allows you to maintain the best condition of your shrimp through every stage of the cold chain: from cooling after harvesting to before or after processing, right through to freezing.
1. Harvest
Live shrimp is uniformly chilled to <0°C in 5 minutes to stop deterioration while reducing labour and handling.
2. Transport
Shrimp is suspended or embedded in Deepchill® to prevent damage and to maintain uniform cooling, ensuring shrimp arrives in the best condition.
3. Reception
Shrimp is stored in Deepchill® to extend the processing window and to enable better handling of peaks without loss of quality.
5. Raw Process Line
Deepchill® is pumped where needed, simplifying process and reducing labour. Shrimp is submerged in Deepchill® and maintained at <0°C.
4. Sort
Shrimp is sorted and returned to Deepchill® maintained at -1°C to -1.5°C. Additives can be added directly into bins for efficiency.
6. Freezer
Improved freezing capacity and efficiency as shrimp is pre-chilled to 0°C before entering freezer, resulting in less shrinkage and higher quality shrimp.
5. Cook and Chill
Cooked shrimp is instantly cooled in Deepchill® to prevent overcooking, bacteria growth and weight loss.
2. Transport
Shrimp is suspended in DeepChill® or embedded in DeepChill® crystals. This prevents damage and maintains uniform cooling through whole batch, ensuring shrimp arrives in the best condition.
3. Reception
Shrimp is temporarily stored in DeepChill® until processing — this extends the processing window and enables better handling of peaks without loss of quality.
4. Sort
Shrimp is sorted and returned to DeepChill® maintained at -1°C to -1.5°C. Additives, if needed, can be added directly to these bins for a more efficient process.
5. Raw Process Line
DeepChill® is automatically pumped where needed, simplifying process and reducing laborious tasks. Shrimp on the process line is completely submerged in DeepChill® maintaining sub-zero temperatures.
5. Cook and Chill
Cooked shrimp is instantly cooled in DeepChill® to prevent overcooking, bacteria growth and weight loss.
6. Freezer
Improved freezing capacity and efficiency since shrimp is now prechilled to 0°C before entering freezer, resulting in higher quality shrimp and less shrinkage
Deepchill® vs. Flake Ice
As a highly perishable product, shrimp is subject to rapid spoilage. Unfortunately, it cannot be undone once it begins. Although it’s impossible to completely stop decay, rapid chilling to sub-zero temperatures significantly slows it down.
A comparative study of cooling rates shows that shrimp (Pandalus Borealis) cooled in traditional flake ice and water did not reach 0ºC even after 18 hours. By contrast, shrimp cooled in Deepchill® was cooled to a consistent -2ºC in less than 5 minutes. By reducing the time taken to chill the shrimp, and maintaining a constant sub-zero temperature, spoilage is greatly reduced.
