Enhancing Efficiency in Vegetable Freezing
Jiesheng's Tunnel freezer is a game-changer for companies freezing vegetables like broccoli florets, carrot dices, corn kernels, and leafy greens. The Tunnel freezer's design focuses on achieving the fastest possible freeze to prevent the formation of large ice crystals within plant cells, which can lead to mushiness and nutrient leakage upon thawing. Automation is at the heart of this automatic freezing system, with programmable logic controllers (PLC) managing belt speed, air temperature, and defrost cycles. Tunnel freezer not only optimizes energy use but also guarantees batch-to-batch consistency. The interior is designed with sanitation as a priority, using food-grade materials and minimizing crevices where debris can accumulate. For processors looking to scale their vegetable freezer operations, this tunnel offers the perfect blend of high capacity (up to 2T/h), operational simplicity, and uncompromising quality preservation, ensuring that the frozen vegetables retain their just-picked appeal.

Extensive Suitability Across Food Types
While optimized for vegetables, this Tunnel freezer competently handles a wide array of IQF and non-IQF products, including fruits, seafood, and prepared foods. Its gentle yet efficient freezing action is suitable for both fragile berries and robust meat cuts. This versatility makes the blast freezing tunnel a highly valuable and flexible asset in any diverse food processing facility.
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.
