The SDD series tunnel quick freezer from WUYE Machinery is designed for industrial food production lines, supporting individual quick freezing (IQF) processing for various food products. Equipped with vertical high-speed airflow and frequency conversion control systems, this equipment adapts to different production scales and freezing requirements, serving food processing facilities, cold chain enterprises and commercial food production operators.
 |  |  |
Adopting vertical high-speed airflow convection technology, this equipment shortens freezing time with continuously adjustable duration. It allows food to pass through the ice crystal zone rapidly, reducing cell wall rupture during the freezing process. Uniform temperature distribution in the chamber supports processing of granular, block and coated food products.
Fitted with a dual-speed motor, the freezer expands application range and lowers energy consumption during operation. The matching refrigeration system uses PLC-based automatic energy adjustment, matching cooling demand to actual production load for stable system operation.
The freezer body adopts a polyurethane foam core with double-sided stainless steel cladding, reducing heat transfer loss during operation. The conveyor system meets food processing hygiene standards, supporting direct contact with food raw materials and finished products.
Equipped with a frequency conversion drive system, the conveyor speed is adjustable within a set range. Three conveyor types (mesh belt, steel belt, strip belt) are available to match different product characteristics. The wide conveyor surface increases effective freezing area per unit time. The equipment has a compact footprint, reducing installation space compared with conventional quick-freezing machines.

High-moisture shrimp processed with slow freezing often face head blackening, soft texture and high juice loss. This tunnel freezer allows shrimp to pass through the ice crystal zone within 10–15 minutes to form fine ice crystals. IQF processing prevents sticking, with juice loss below 5% after thawing, meeting export quality requirements.
Tender fish fillets are prone to flattening and deformation in traditional freezing, leading to brittle texture after thawing. A steel belt conveyor is recommended for stable transport, paired with vertical high-speed airflow for deep freezing. This method maintains product shape and moisture, keeping products intact during cooking, suitable for retail packaging.
Slow-frozen meat patties, chicken breasts and pork chops often suffer juice loss, dry texture and clumping. This tunnel freezer achieves rapid deep freezing at -35℃ or below within 15–25 minutes. The process results in approximately 5% juice loss, bright meat color and full non-sticking performance, enabling direct packaging after freezing.
Coated shrimp and tempura shrimp often face coating loss and shape deformation during freezing. The equipment applies rapid surface freezing at -40℃ in the initial stage to lock the coating structure, followed by uniform deep freezing. This keeps the coating intact, delivering crispy texture after frying, suitable for chain restaurant supply.
Semi-finished raw materials are sensitive to unit costs, and slow freezing leads to short shelf life. This equipment supports rapid deep freezing at -30℃, with products ready for direct storage after processing. The process extends shelf life to over 18 months and reduces unit processing cost by 15–20%.
The refrigeration system adopts no-barrel no-pump technology with multiple parallel units and multi-level energy regulation, matching actual production cooling demand. Compressors and accessories are sourced from domestic and international suppliers, with stable operation and long service life. Compared with single-unit systems, this design saves over 30% energy. It can match multiple evaporators for different evaporation temperatures, keeping the system in an energy-saving running state. The integrated design saves machine room space and facilitates maintenance. Fault separation technology ensures partial failures will not interrupt overall production.
The STC series evaporative condenser uses a reverse flow design: refrigerant flows through the coil, cooling water moves downward from the top, and air rises from the bottom to carry away heat. Water passes through a packing layer for cooling and collects in the bottom pan. A top water collector captures droplets to reduce water loss, lowering operating costs for commercial production.
