Application
Scenario 1: Shrimp
Challenges: Slow-frozen shrimp with high water content often suffer from blackened heads, mushy texture, and significant juice loss. By rapidly passing through the ice crystal zone (10–15 minutes), fine ice crystals form without rupturing the cell walls. Benefits: IQF (Individual Quick Freezing) prevents sticking, with juice loss <5% after thawing, achieving export-grade quality.
Scenario 2: Fish Fillets
Challenge: The tender, delicate texture of fish fillets makes them prone to flattening and deformation during traditional freezing, resulting in brittleness upon thawing. We recommend using a steel belt conveyor for even transport, combined with vertical high-speed airflow for deep freezing. Benefit: Retains shape, excellent moisture retention, holds together during pan-frying or grilling, and is suitable for retail packaging.
Scenario 3: Meat Portions
Challenges: Meat patties, chicken breasts, and pork chops lose juices, become dry and tough, and freeze into large, clumped masses after slow freezing. Rapid deep-freezing at -35°C or below in the tunnel (15–25 minutes). Benefits: Juice loss of approximately 5%, bright meat color, 100% non-sticking, and ready for direct packaging.
Scenario 4: Value-Added Seafood
Challenge: Coated shrimp and tempura shrimp often lose their coating and become misshapen. Rapid “shell-locking” at -40°C in the initial stage, followed by uniform freezing. Benefit: Coating stays intact; results in crispy, plump texture after frying; suitable for chain restaurants.
Scenario 5: Bulk Raw Materials
Challenge: Semi-finished raw materials are sensitive to unit costs, and slow freezing results in a short shelf life. Rapid deep-freezing at -30°C followed by direct storage. Benefit: Shelf life extended to over 18 months; unit costs reduced by 15–20%.
Impact tunnel quick freezer
Speed adjustable
Adopt the frequency conversion drive system. The speed can be adjusted within a certain range.
A wide range of applications
Applied in fruit, seafood, meat and other granular and block food frozen
It covers a small area
Small floor area, compared with the conventional quick-freezing machine to reduce the quick-freezing machine installation space
Freezing quickly
The vertical high-speed airflow greatly reduces the freezing time, and the freezing time is continuously adjustable
Our company one-stop set of quick-frozen solutions, using domestic and foreign advanced refrigeration design concept multiple parallel units, no barrel no pump technology, through the PLC in the program automatic energy adjustment to match the ever-changing cooling cooling that the refrigeration system maintain the best efficiency, to achieve energy saving, reduce operating costs.
1. Multiple units are connected in parallel and multi-level energy regulation is used to achieve timely and reasonable matching according to the actual refrigeration capacity required for production, which saves more than 30% energy compared with a single unit.
2.It can match multiple evaporators to achieve one machine suitable for different evaporation temperatures, making the refrigeration system run in the most energy-saving working state.
3. Adopt high-quality compressors and accessories from home and abroad, with reliable performance, stable operation and long service life.
4. Simple design, the refrigeration main unit, accessories and controls are concentrated in one body, which fully saves the machine room space and is extremely convenient for operation and maintenance.
5. The use of fault separation technology can ensure that when some machines fail, other machines can still operate normally, ensuring normal and continuous production for customers.
STC Series Evaporative Condensers – Energy Saving, Low Operating Cost
The STC series evaporative condensers are built with a practical design that combines proven cooling principles with efficient water and air flow. These units are popular in many industrial settings because they save both energy and water while keeping operating costs low.
How it works:
Refrigerant flows through the coil. Cooling water moves downward from the top, while natural air rises from the bottom. The reverse flow takes heat away from the refrigerant into the air.
Water that runs over the coil then passes through a packing layer, gets cooled, and finally collects in the water pan below. A water collector at the top catches small water droplets, which helps reduce water loss.
