Our spiral freezer utilizes precision airflow control and rapid freezing technology to achieve individual quick freezing, ensuring shrimp and other seafood products freeze separately without adhesion, and form minimal ice crystals to lock in natural texture, freshness, and nutritional value, delivering premium frozen products that elevate market competitiveness for processing enterprises.
The fully automated continuous freezing design eliminates manual handling throughout the freezing process, seamlessly integrating with upstream and downstream processing lines to support 24/7 uninterrupted production. This automation reduces labor requirements, minimizes human contact with products to lower contamination risks, and significantly increases production efficiency to meet large-volume order demands.
Engineered specifically for the harsh, high-salinity, high-moisture environment of seafood processing, the equipment features a full SUS304 stainless steel structure, anti-rust evaporator components, and moisture-proof, corrosion-resistant electrical systems. This heavy-duty build prevents corrosion and degradation over time, extending the equipment’s service life and reducing maintenance costs.
The system offers full flexibility to adapt to your unique production requirements, with customizable conveyor belt widths, freezing time settings, refrigeration configurations, and equipment layouts. Whether processing shrimp, other seafood products, or other frozen goods, the equipment can be tailored to match your product specifications and facility constraints.
This IQF spiral freezer is purpose-built for a wide range of quick freezing applications across seafood processing enterprises and frozen food production facilities. Its core application is individual quick freezing of shrimp, where it delivers consistent, non-adhesive freezing results for both raw and processed shrimp products. It is also optimized for freezing a full range of seafood including fish fillets, shellfish, squid, and other aquatic products, as well as frozen prepared seafood items. Beyond seafood, the equipment suits freezing a variety of other food products including flour-based goods, jelly, and prepared frozen foods, making it a versatile asset for multi-product frozen food production facilities.
Yes, the equipment is specifically designed for individual quick freezing, with precision airflow distribution and optimized conveyor design to ensure each shrimp freezes separately and maintains its individual form, eliminating adhesion and clumping during the freezing process.
The entire main structure of the freezer is constructed from SUS304 stainless steel, with anti-rust aluminum finned tubes for the evaporator and moisture-proof, corrosion-resistant electrical components, engineered to resist corrosion from saltwater and high moisture.
Yes, the freezing time, chamber temperature, and conveyor speed are all fully adjustable, allowing operators to fine-tune the freezing parameters based on the type, size, and required final temperature of the product, ensuring optimal freezing results for every batch.
