Condenser

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 are the latest type of evaporative condensers developed by our company by absorbing the latest technologies and manufacturing processes at home and abroad. They are one of many types of condensers and are widely used due to their energy and water saving, high efficiency and low operating cost.

When the equipment is running, the refrigerant in the coil is reversely exchanged by the cooling water from top to bottom and the natural air from bottom to top, and the heat is taken away from the air; the water passing through the coil flows into the packing layer and then flows into the water pan after being cooled. The small water droplets passing through the top layer are collected by the water collector, thus reducing the water escape rate.

Material & Hygiene

In the seafood processing sector, sanitation is absolutely non-negotiable. The physical construction of your equipment must actively prevent contamination and facilitate rigorous, fast daily cleaning protocols.

Premium 304 Stainless Steel: Every surface that comes into contact with your product, as well as the robust exterior housing, is forged from high-grade 304 stainless steel, offering ultimate resistance to corrosion from saltwater and harsh cleaning chemicals.
Food-Grade Assurance: The materials used throughout the freezing zone strictly comply with international food safety regulations, ensuring your products are safe and certified for global export markets.
Washdown-Ready Design: The smooth, polished surfaces and thoughtfully designed drainage pathways prevent the accumulation of organic debris, making high-pressure washdowns fast, safe, and highly effective.
Odor and Stain Resistance: The non-porous nature of the steel and specialized belts ensures that no lingering fish odors or organic stains compromise the flavor profile of the next batch of production.

Insulation & Temperature Control

Maintaining a stable, ultra-low temperature environment is the secret to perfect Individual Quick Freezing (IQF). Our superior insulation architecture ensures that every ounce of cooling energy generated stays exactly where it belongs—inside the freezing tunnel.

Polyurethane Foam Core: The thermal storage body is constructed using high-quality, high-density polyurethane foam injected between double-sided stainless steel panels, creating an impenetrable thermal barrier.
Zero Cold Leakage: Precision-engineered seals and interlocking panel joints prevent any ambient warm plant air from infiltrating the freezing chamber, eliminating the risk of internal frost buildup and temperature fluctuations.
Consistent Microclimate: By locking the cold air inside, the system maintains a highly stable internal microclimate, ensuring that the first shrimp entering the tunnel freezes just as perfectly as the last one of the day.
Reduced Compressor Strain: Because the insulation is so exceptionally effective, the refrigeration compressors do not have to work overtime to compensate for heat loss, thereby extending the mechanical lifespan of the entire system.

Space Utilization

Floor space in a certified food processing facility is incredibly expensive. We fully understand that maximizing your production output per square meter is crucial for long-term operational profitability and expansion.

Compact Integrated Design: The refrigeration main unit, critical accessories, and intelligent control panels are concentrated into a single, streamlined body, drastically reducing the overall footprint of the installation.
Optimized Floor Area: Compared to conventional, sprawling quick-freezing setups, our impact tunnel freezer covers a significantly smaller area, freeing up valuable room for additional processing lines or automated packaging stations.
Simplified Machine Room: Because the system is highly integrated, it fully saves machine room space. You will not need to construct expansive secondary facilities just to house the refrigeration racks and piping.
Convenient Maintenance Access: Despite its compact nature, the layout is meticulously planned to ensure that your maintenance technicians have easy, unobstructed access to all critical components for routine servicing and checks.

FAQ

To assist you in making an informed procurement decision, we have compiled detailed answers to the most common technical inquiries regarding our industrial tunnel freezing systems.

1. What is the difference between the strip band, steel belt, and mesh belt options?

The choice of belt depends entirely on your specific product. The solid steel belt is ideal for wet, sticky products like raw fish fillets as it is easy to scrape clean and leaves no marks. The mesh belt provides excellent airflow from underneath, making it perfect for granular items like shrimp or diced fruits. The strip band offers a unique balance of support and airflow for irregularly shaped seafood like squid tubes.

2. How does the PLC automatic energy adjustment system work?

Our sophisticated PLC system continuously monitors the thermal load inside the freezing tunnel. If you are running a lighter batch of shrimp, the system automatically dials back the compressor output. When a heavy load of thick meat blocks enters, it ramps up the power. This dynamic matching ensures you only use the electricity strictly necessary for perfect freezing, saving up to 30% in energy costs over time.

3. Can this machine accommodate power supplies other than 380V/50Hz?

Yes, absolutely. While 380V/50Hz is our standard specification, we fully recognize that industrial power grids vary globally. Our electrical engineering team can customize the motors, drives, and control panels to match the specific three-phase voltage requirements of your local facility, ensuring plug-and-play compatibility upon arrival.

4. How do I clean and maintain the interior of the freezing tunnel?

The interior is designed with maximum sanitation in mind. The 304 stainless steel surfaces are fully welded and polished to prevent bacterial harborage. The tunnel features accessible side doors that allow your sanitation crew to easily reach the belt and internal chambers with high-pressure washdown equipment. Furthermore, the sloped floor design ensures rapid drainage of cleaning fluids and melted ice.

5. What information do I need to provide to get a customized freezing solution?

To engineer the perfect system for your exact needs, we require a few key details: the specific type of production (e.g., whole fish, peeled shrimp, diced meat), your target output capacity in kg/h, the size of the product or package, the required inlet and outlet temperatures, your preferred refrigerating system or cold source (such as R404A or R507), and your facility's three-phase voltage specifications.
