Unique Benefits of Our IQF Freezer Solutions

Quiet Operation and Energy Efficient

Our IQF freezers come equipped with features like heat retention and variable frequency drives (VFDs), which yield an astonishing 30% energy savings compared to conventional freezers. Advanced insulation materials help reduce heat loss while the intelligent defrosting system optimizes maintenance energy tasks. Due to our low-vibration design, stabilized operations can be shared with other production units. These IQF freezers sustain sub 75dB noise levels ensuring workplace noise standards while the low vibration design helps large facilities save over $10,000 a year in energy costs.

An IQF (Individual Quick Freezing) freezer tailored for food factories is a specialized piece of equipment engineered to handle high-volume, continuous freezing of food products while maintaining individual piece integrity, nutritional value, and food safety—critical requirements for large-scale food processing operations. Unlike small-scale IQF freezers designed for batch processing, food factory IQF freezers are built for 24/7 operation, with capacities ranging from 500 kg/h to over 5,000 kg/h, making them suitable for freezing a diverse array of factory-produced goods, including frozen vegetables (carrots, peas, broccoli), fruits (strawberries, mangoes, blueberries), seafood (shrimp, scallops, fish fillets), poultry (chicken breasts, nuggets), and prepared meals (pasta dishes, stir-fries). The core technology of a food factory IQF freezer revolves around the principle of rapid, uniform freezing: cold air (typically at -30°C to -40°C) is circulated at high velocity through a freezing tunnel or belt system, ensuring that each product piece is surrounded by cold air individually—preventing clumping and ensuring that every item thaws evenly later. This is particularly important for food factories, as clumped products lead to inconsistent cooking, consumer dissatisfaction, and increased waste. To support continuous operation, these freezers are integrated with upstream processing lines (e.g., washing, cutting, blanching equipment) and downstream packaging systems via automated conveyors, minimizing manual handling and reducing the risk of cross-contamination—aligning with food safety standards like HACCP and ISO 22000. Design features specific to food factory use include robust construction (304 stainless steel frames and contact surfaces) that withstands frequent cleaning and sanitization, corrosion-resistant components (to handle moisture from frozen products), and advanced control systems (PLC-based or touchscreen interfaces) that allow operators to monitor and adjust key parameters (temperature, air velocity, conveyor speed) in real time. Many models also incorporate energy-saving technologies, such as heat recovery systems (which capture waste heat to pre-cool incoming products) and variable-speed fans (that adjust airflow based on product volume), reducing the high energy consumption typically associated with industrial freezing. Food factory IQF freezers are also designed to be flexible, with adjustable belt widths and freezing times to accommodate different product sizes and types—for example, smaller products like peas require shorter freezing times than larger items like chicken thighs. Additionally, compliance with global regulatory standards is a priority: these freezers meet CE (EU), FDA (US), and JAS (Japan) requirements, ensuring that food factories can export their frozen products to international markets without barriers. Maintenance and after-sales support are critical for food factories, as downtime can lead to significant production losses; thus, reputable manufacturers (like KANGBEITE) offer regular maintenance schedules, on-site repair services, and spare parts availability to minimize operational disruptions. In summary, a food factory IQF freezer is an indispensable asset that enables large-scale food processors to produce high-quality, safe, and marketable frozen products efficiently, supporting their ability to meet global demand and maintain competitive advantage in the food industry.

Frequently Asked Questions

Who is suitable for IQF freezing?

QF technology works best with single loose items that need to be freezing rapidly such as: Seafood: Shrimp, fish fillets, and shellfish. Fruits & Vegetables: Leafy greens, diced vegetables, and berries. Meat & Poultry: Meatballs, sausages, and diced chicken. Convenience Foods: French fries, dumplings, and various snacks. It is also applicable to the floral and pharmaceutical industries where rapid freezing is needed.

Perfect for Our Frozen Vegetable Line

As a major supplier of frozen vegetables, we wanted an IQF product that maintained cripsness and color. soot’s tunnel freezer did not disappoint. Our diced carrots and peas are able to retain their texture and nutrients for a year’s worth of storage. The rapid changeover from carrots to green beans takes only fifteen minutes, and the hygienic design makes daily maintenance effortless. This has improved our productivity and quality tremendously.

Intelligent Temperature Control System

Intelligent Temperature Control System

For real-time supervision of refrigeration parameters, the PLC based HMI screen allows controlling and monitoring for more than 50+ products like seafood, veggis, ready meals etc. Advanced sensors measure the temperature of the product to be frozen, Also, airflow is controlled to use energy optimally during freezing time.
Dual-Zone Freezing Technology

Dual-Zone Freezing Technology

The patented dual-zone design of our freezer units increases the efficiency of the moisture-rich products by reducing the overall freezing time by 15%. Pre-freezing is done in the first zone -20° to form a protective crust. The rest of the freezing is done in the second zone -40°. This also eliminates moisture loss.
Sustainability Features

Sustainability Features

Heat Recovery: Conserves carbon footprint by 20% by recovering waste heat to sparsely warm air as borading pre-warm or for other processes. Recyclable Insulation: Polyurethane foam that is eco-friendly and has no Ozone Depletion Potential (ODP) is considered environmentally friendly. Waterless Cooling: The elimination of water usage with air-cooled condensers aligns with production practices that are drought tolerant. These features help achieve sustainability objectives while lessening the operational footprint on limited resources.
