Frozen Blackfish Fillets by SPEEDCRYO® Liquid Nitrogen IQF Tunnel Freezer
If you are looking for a way to preserve the freshness and quality of your blackfish fillets, you might want to consider using a liquid nitrogen IQF tunnel freezer. This is a type of freezer that uses liquid nitrogen as the cooling agent, which can rapidly freeze the fish fillets without damaging their texture, flavor, or nutritional value. In this blog post, we will introduce you to the benefits of using liquid nitrogen IQF tunnel freezer for freezing blackfish fillets, and share a case study of how one of our customers successfully implemented this technology in their seafood processing plant.
The application of the Liquid Nitrogen IQF Tunnel Freezer is extensive, spanning across industries such as aquaculture, baking, and quick-freezing of fruits and vegetables. This is attributed to its capability to provide an exceptionally low operating temperature (the evaporation temperature of liquid nitrogen is -196℃, while the working temperature of the Liquid Nitrogen IQF Tunnel Freezer can typically go as low as -120℃). The benefits derived from this ultra-low operating temperature include a compact footprint, high production capacity, and superior quality of frozen products. The following is a more detailed overview of the Liquid Nitrogen IQF Tunnel Freezer.
Liquid nitrogen IQF tunnel freezer is a type of freezer that uses liquid nitrogen as the cooling agent to freeze food products individually and quickly. IQF stands for individually quick frozen, which means that each piece of food is frozen separately and not stuck together. This allows for easy portioning and storage of the frozen products, as well as better preservation of their quality and appearance.
Liquid nitrogen is a colorless, odorless, and extremely cold liquid that has a boiling point of -196°C (-321°F). When it comes into contact with food products, it instantly vaporizes and absorbs heat from them, causing them to freeze rapidly. The freezing process takes only a few minutes, depending on the size and shape of the food products. The fast freezing rate prevents the formation of large ice crystals in the food products, which can damage their cell structure and cause drip loss, texture deterioration, and flavor loss.
Liquid nitrogen IQF tunnel freezer consists of a conveyor belt that transports the food products through a tunnel where liquid nitrogen is sprayed from nozzles. The liquid nitrogen creates a cold mist that envelops the food products and freezes them quickly and evenly. The frozen products are then discharged from the other end of the tunnel and packaged for storage or distribution.
Blackfish is a type of fish that has a firm and flaky flesh with a mild and sweet flavor. It is rich in protein, omega-3 fatty acids, and other nutrients that are beneficial for human health. However, blackfish is also highly perishable and prone to spoilage if not handled properly. Therefore, freezing is an effective way to extend the shelf life and maintain the quality of blackfish fillets.
However, not all freezing methods are suitable for blackfish fillets. Some conventional freezers use air or mechanical refrigeration to freeze food products, which can take hours or even days to complete. During this long freezing process, large ice crystals can form in the blackfish fillets, which can damage their cell structure and cause drip loss, texture deterioration, and flavor loss. Moreover, conventional freezers can also cause dehydration, oxidation, and freezer burn on the surface of the blackfish fillets, which can affect their appearance and taste.
On the other hand, liquid nitrogen IQF tunnel freezer can freeze blackfish fillets quickly and individually, without causing any of these problems. By using liquid nitrogen IQF tunnel freezer, you can enjoy the following benefits:
One of our customers is a seafood processing company that specializes in producing high-quality frozen seafood products for domestic and international markets. They have been using liquid nitrogen IQF tunnel freezer to freeze blackfish fillets for several years, and they are very satisfied with the results.
Before using liquid nitrogen IQF tunnel freezer, they used a conventional blast freezer to freeze blackfish fillets, which took about 2 to 4 hours to complete. During this long freezing process, they noticed that the blackfish fillets lost a lot of moisture and weight, and their texture and flavor deteriorated significantly. Moreover, they had to deal with high energy consumption and maintenance costs, as well as limited production capacity and flexibility.
After switching to liquid nitrogen IQF tunnel freezer, they were able to freeze blackfish fillets in just 10 minutes, which greatly improved their product quality and yield. They also reported that the blackfish fillets retained their freshness, flavor, texture, and nutritional value, and had no signs of drip loss, dehydration, oxidation, or freezer burn. Furthermore, they were able to reduce their energy consumption and operating costs by 50%, and increase their production capacity and efficiency by 300%. They also enjoyed more flexibility and convenience in freezing different sizes and shapes of blackfish fillets, as well as other seafood products.
If you are looking for a way to freeze blackfish fillets with high quality and efficiency, you should consider using liquid nitrogen IQF tunnel freezer. This is a type of freezer that uses liquid nitrogen as the cooling agent to freeze food products individually and quickly, without damaging their quality or appearance. By using liquid nitrogen IQF tunnel freezer, you can preserve the freshness, flavor, texture, and nutritional value of blackfish fillets, prevent drip loss, dehydration, oxidation, and freezer burn on blackfish fillets, reduce energy consumption and operating costs compared to conventional freezers, increase production capacity and efficiency by freezing large batches of blackfish fillets in a short time, enhance food safety by minimizing bacterial growth and cross-contamination during freezing, improve customer satisfaction by offering high-quality frozen blackfish fillets that are easy to portion and store.
