As a professional manufacturer of liquid freezing fresh-locking equipment, we are committed to providing high-efficiency, energy-saving and cost-effective Liquid Immersion Freezing solutions for global food processing enterprises. Our core products include Tunnel Liquid Freezer, Lifting Type Freezing Machine, and customized large-scale continuous liquid hypothermia freezing equipment, which are widely used in aquatic products, prepared food, meat and poultry processing industries. With the core technology ofCell-level Quick Freezing, our equipment realizes true “fresh locking at the cellular level”, and serves as an ideal Liquid Nitrogen Alternative to help enterprises reduce costs while improving product quality.
Product Overview: Redefine Fresh Locking with Liquid Hypothermia Technology
Our Liquid Immersion Freezing Machine (also known as liquid hypothermia fresh lock machine) adopts advanced Low Temperature Liquid Freezing technology, which uses food-grade ultra-low temperature liquid medium to directly contact food materials, realizing rapid and uniform freezing from the surface to the core. Different from traditional air freezing and expensive liquid nitrogen freezing, our equipment combines the advantages of high efficiency, energy saving, high quality and low cost, and is specially designed for scenarios such as aquatic product cell-level quick freezing (tuna, salmon, shrimp, etc.), prepared food fresh locking, and meat and poultry quick freezing, solving the pain points of high loss, poor quality and high cost in traditional freezing methods.
Core Technology & Advantages
1. Cell-level Quick Freezing: Lock Freshness at the Source
Adopting the core principle of Hypothermia Fresh Lock, our liquid immersion freezing equipment can quickly lower the core temperature of food to -18℃ below in 3-15 minutes (depending on the size of the material). The ultra-fast freezing speed enables the water in the food cells to form tiny and uniform ice crystals (5-10μm), which avoids damaging the cell membrane and cell wall—effectively solving the problems of juice loss, texture hardening and nutrient loss caused by large ice crystals in traditional freezing methods. After thawing, the food can retain more than 95% of its original moisture, nutrients and flavor, and the thawing loss rate is controlled below 2%, reaching the fresh-keeping standard of sashimi level.
2. Ideal Liquid Nitrogen Alternative: High Cost Performance & Stable Operation
As a high-quality Liquid Nitrogen Alternative, our equipment breaks the bottleneck of high operation cost of liquid nitrogen freezing equipment. The food-grade low-temperature liquid medium we use is recyclable, with a consumption of only 3-5 kg per ton of frozen products, and the operation cost is 1/5-1/10 of that of liquid nitrogen freezing equipment. At the same time, it avoids the potential safety hazards such as volatilization of liquid nitrogen and difficult storage, and the equipment runs stably with low failure rate, which greatly reduces the later maintenance cost and production risk for enterprises.
3. Two Core Models: Tunnel & Lifting Type, Adapt to Various Scenarios
- Tunnel Liquid Freezer: Suitable for large-scale continuous production, with automatic conveyor belt design, which can realize seamless connection with the front and rear processing lines. It is especially suitable for batch freezing of aquatic products (tuna, salmon), prepared food, and meat pieces, with a daily output of 5-50 tons. The tunnel-type structure ensures uniform freezing of materials, high production efficiency, and can save 40% of labor costs compared with traditional equipment.
- Lifting Type Freezing Machine: Customized for small and medium-sized enterprises or special-shaped materials, with a liftable tank body design, which is easy to clean and disinfect, and meets HACCP food safety standards. It is flexible and convenient to use, suitable for small-batch, multi-variety freezing needs, such as small pieces of seafood, prepared dishes, and high-end meat products, and can be customized according to the size of the factory and production needs.
4. Safety & Environmental Protection: Meet Global Food Safety Standards
The whole machine is made of 304 stainless steel, which is corrosion-resistant, high-temperature resistant and easy to clean. The used low-temperature liquid medium is food-grade, non-toxic, non-corrosive, and has passed SGS certification, ensuring that it does not pollute food and meets the food safety standards of Europe, America, Southeast Asia and other regions. At the same time, the equipment adopts energy-saving refrigeration system, which consumes 40% less electricity than traditional freezing equipment, and reduces carbon emissions by 50%, realizing green and low-carbon production.
Application Scenarios
Our Liquid Immersion Freezing equipment is widely used in various food processing fields, focusing on solving the fresh-keeping problems of high-value products, and is deeply trusted by customers in more than 20 countries and regions around the world:
- Aquatic Products Processing: Tuna, salmon, shrimp, crab, tilapia and other aquatic products, realizing cell-level quick freezing, retaining the tender texture and rich nutrients of seafood, and extending the shelf life to 12-18 months under -18℃ storage conditions.
- Prepared Food Industry: Various prepared dishes, quick-frozen noodles, meat products, etc., solving the problems of poor taste and easy deterioration of prepared dishes after freezing, and helping enterprises expand the sales radius of products.
- Meat & Poultry Processing: Beef, pork, chicken, duck and other meat products, reducing juice loss during freezing and thawing, keeping the meat tender and juicy, and improving the product grade.
- High-end Food Processing: Sashimi, high-end pastries, fresh fruits and vegetables, etc., which require high fresh-keeping standards, realizing “zero loss” of fresh-keeping and ensuring the original flavor and quality of products.
