Impact tunnel quick freezer
Speed adjustable
Utilizes high-velocity, ultra-low-temperature airflows to rapidly crust-freeze products, minimizing dehydration and ice crystal formation. This quick passage through the “danger zone” effectively locks in original moisture, flavor, texture, and nutritional value.
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
Continuous Operation, Maximizes Output
Provides true 24/7 non-stop freezing capability. Products enter and exit continuously, eliminating batch cycle waiting times and dramatically increasing overall plant throughput compared to batch-type freezers.
High Efficiency & Uniformity
Advanced airflow design and precision temperature control ensure every product receives identical freezing conditions, guaranteeing consistent quality. Energy recovery systems optimize thermal efficiency, reducing operational costs.

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.

The Liquid Nitrogen Tunnel Freezer utilizes ultra-low temperature (-196°C) liquid nitrogen (LN2) to achieve instant freezing, preserving product freshness, color, and nutritional value—critical for high-value items. By rapidly lowering product temperatures (at a rate of 5–10°C per second), it minimizes cell damage in delicate foods like sushi-grade fish, gourmet pastries, and probiotic yogurts. This equipment is also used in pharmaceutical processing for stabilizing temperature-sensitive biologics.
The 24-Hour Cycle Plate Freezer is specifically designed for commercial meat processing, enabling continuous freezing of bulk meat products such as beef cuts, poultry carcasses, and pork loins. Its hydraulically operated stainless steel plates apply uniform pressure to meat blocks, ensuring rapid heat transfer and minimizing ice crystal formation—critical for preserving muscle texture and juiciness. This equipment is widely used in abattoirs, meat packing plants, and distribution centers, supporting seamless integration into post-slaughter processing lines.
The Multipass Belt IQF Tunnel Freezer is engineered for large-scale food processing, offering low shrinkage and high product integrity across high-volume production runs. Its multi-tiered belt system maximizes freezing efficiency by exposing products to cold air (-30°C to -40°C) during multiple passes, making it ideal for dense or irregularly shaped items like French fries, chicken nuggets, and pizza toppings. This equipment integrates seamlessly into automated lines, from pre-processing to packaging, ensuring consistent quality in mass-produced frozen foods.
The Industrial IQF Freezer Machine employs Individual Quick Freezing (IQF) technology to freeze food products individually, preventing clumping and preserving texture—key for products sold as single pieces (e.g., frozen peas, shrimp, and berries). It uses high-velocity cold air (-30°C to -40°C) to create a protective ice glaze around each item, locking in moisture and nutrients. This equipment is essential for processors of fruits, vegetables, seafood, and ready-to-eat meals, supporting both retail and foodservice supply chains.
