The preservation dilemma in the pre packaged food industry
1. Cell damage leads to quality decline: Traditional quick freezing machines use flat freezing or tunnel freezing techniques, with a freezing time of up to 1-2 hours. The water in fish slices and meat cells forms large ice crystals, and after thawing, the meat becomes dry and the juice is lost, resulting in a decrease in taste of more than 30%;
2. Microbial reproduction shortens shelf life: If the freezing temperature or cold chain transportation does not meet the standards, bacteria are prone to grow after thawing, resulting in a shelf life of less than 15 days;
3. The problem of "consistency" in large-scale production: manual packaging or semi-automatic production lines result in significant differences in the shape of thawed products from different batches, making it difficult for brands to establish standardized product systems.
These pain points not only drive up the loss rate (industry average loss reaches 20% -25%), but also trap pre packaged dishes in the quagmire of "low price competition".
CBFI Double Spiral Freezing Machine
1. Double helix structure: a breakthrough from "uniform freezing" to "instantaneous freshness locking"
The core innovation of CBFI double spiral freezer lies in its unique dual axis convection freezing technology:
• Ultra low temperature quick freezing: With a rapid freezing capacity of -45 ℃ to -55 ℃, fish slices and other ingredients can be frozen from room temperature to -18 ℃ in 8 minutes, which is more than 10 times faster than traditional equipment;
• Double spiral uniform flow system: Through the synchronous movement of the dual axis spiral conveyor belt, the ingredients are uniformly frozen in the three-dimensional circulating cold air flow, and the ice crystal diameter is precisely controlled within 1 micron to avoid cell rupture;
• Intelligent temperature control zoning: pre-set freezing curves for different ingredients (such as fish fillets, beef, shrimp), automatically adjust temperature gradients and dwell times to ensure stable storage of umami substances.
2. Technological value: upgrading the industrial chain from "preservation" to "value-added"
• Lock in freshness and nutrition: Quickly freeze and inhibit enzyme activity, with a preservation rate of over 95% for umami amino acids (such as glutamic acid) in fish slices;
• Improved meat texture recovery: Micro ice crystal freezing reduces the protein loss rate after thawing to 5%, and there is no difference in meat compactness compared to freshly cut ingredients;
• Leapfrog increase in shelf life: At -18 ℃, the shelf life of pre made fish fillet dishes can be extended to over 90 days, and that of prepared dishes can reach up to 60 days.
3. Production efficiency: driven by the "dual engines" of cost reduction and efficiency improvement
• Cliff like decrease in loss rate: from 20% -25% in traditional freezing to 3% -5%, saving over 500000 yuan in annual costs per production line;
• 5 times increase in production capacity: The double helix structure enables continuous production, with a daily processing capacity of 6 tons, meeting the needs of the "central kitchen+instant retail" model;
• Flexible production adaptation: modular design supports diversified product switching from fish fillet, Rice-meat dumplings to the whole chicken, reducing the idle cost of equipment.
In today's fiercely competitive pre packaged food industry, the CBFI double spiral quick freezing machine has broken the cognitive gap of "freezing means low-quality" with its "micron level freshness locking" technology. When a frozen fish fillet can maintain its elasticity even after thawing, and when a box of pre made dishes can cross thousands of miles and still taste as fresh as freshly cooked, companies have mastered the "golden key" to the market - driving quality with technology, leveraging scale with quality, and winning the future with scale.
