▌Product Description
The Meatech MT-IQF IQF tunnel freezer individually quick-freezes food products — chicken nuggets, meatballs, fish pieces, vegetables, fruit, diced meat — to -18°C exhaust temperature in a continuous 20–45 minute freeze cycle, producing free-flowing individually frozen pieces that do not clump together in the retail pack. The "individually quick frozen" principle is achieved by the combination of the tunnel format (each piece spends a defined residence time in the freeze zone) and the fluidisation airflow that lifts and separates small pieces during freezing, preventing adjacent pieces from freezing together before their surfaces are individually frozen.
Seven models from SSD-100 (1,300 mm belt width, 10 kW, 7,700 mm length) to SSD-1500 (3,000 mm belt width, 41 kW, 21,700 mm length) cover the full range from pilot-scale and central kitchen IQF production to large industrial frozen food manufacturing. Installed power scales from 10 kW for the smaller models to 41 kW for the two widest models — the power figure covers the refrigeration system, fans, and conveyor drive. All models share the same 20–45 minute freezing time range and -18°C exhaust temperature, with actual throughput capacity determined by belt width, product layer depth, and product type.

▌Solution Applications
Solution / Line | Role of MT-IQF |
Chicken Nuggets & Patty Line | IQF freezing after the air dryer stage. SSD-500 or SSD-800 for standard industrial nugget lines; SSD-300 for smaller operations. Individual freezing ensures nuggets arrive free-flowing in retail packs. |
Meatball Processing Line | IQF freezing of cooked meatballs. The meatball round shape makes it ideal for fluidisation IQF — pieces separate easily during freezing. |
IQF Vegetable Lines | Primary freezing stage after air drying. SSD-800 to SSD-1500 for vegetable lines at 1,000–3,000 kg/h throughput. Belt width selection is based on the product layer depth and desired throughput. |
▌FAQ
Q: How is the correct MT-IQF model selected for my production line?
A: The primary selection parameters are belt width (determines maximum throughput for a given product layer depth) and installed power (determines the refrigeration capacity and freezing rate). For a target of 1,000 kg/h of chicken nuggets: the SSD-500 (2,000 mm belt, 19 kW) or SSD-800 (2,200 mm belt, 19 kW) are typically sized for this range depending on nugget size and layer depth. For IQF vegetables at 2,000 kg/h, the SSD-1000 or SSD-1500 (3,000 mm belt, 41 kW) is appropriate. Meatech calculates the correct model from your product type, piece size, target throughput, and inlet product temperature.
Q: What is the product inlet temperature requirement?
A: Products should enter the IQF tunnel at below 30°C for optimum freezing efficiency and tunnel performance. Products above 40°C at the inlet significantly increase the refrigeration load and extend the time required to reach -18°C core temperature, potentially requiring a longer tunnel (larger model) to achieve the same throughput. The MT-AD air dryer preceding the IQF tunnel serves both the moisture removal and initial cooling functions, typically reducing inlet product temperature by 10–20°C before the IQF stage.
