IQF Self-Stacking Spiral Freezer

Our IQF self-stacking spiral freezer is the perfect solution for quick and even freezing of your products. The vertical cold airflow area ensures that each product is individually frozen, resulting in a continuous large output. Plus, the ice crystal formation area ensures that your products are frozen evenly and quickly and are always delicious and juicy.

Our IQF self-stacking spiral freezer is designed to cater to all your needs. It can freeze all common products, including poultry, cut meat, prepared products, ready-to-eat products, wheaten food, baked products, aquatic food, and more. It is especially suitable for products that require high cooking temperature and high-quality standards, such as frying, baking, and steaming.

Features
Unique conveyor belt system: Our closed product freezing area maximizes cooling capacity, while preventing product blow-off. The belt requires only a small power motor, which means significant energy savings. Additionally, our belt features an automatic tensioning device to prevent it from turning over.
Efficient vertical airflow: Our IQF spiral freezer features a centrifugal fan with large air pressure and air volume, requiring fewer fans. The fan is placed on the "dry side" of the evaporator, optimizing airflow velocity through the evaporator. Vertical cold airflow is delivered quickly to the freezing area, resulting in shorter quick-freezing time, lower drying consumption, and higher quality products. Our highly efficient stainless steel tube evaporator is crafted with aluminum-magnesium alloy cooling fins, ensuring easy cleaning and defrosting With an adjustable air pressure balance device, our system balances airflow and increases cooling capacity, preventing heat exchange inside and outside the shell. Our automatic defrosting system (CADF) improves the heat exchange efficiency of the evaporator and extends the equipment's running time. Our cleaning system ensures no bacteria residue, providing a more hygienic environment.
Our bottom plate design prevents cold leakage and bridging, reduces power consumption, and avoids submergence of the floor insulation layer in water. Our freezer is designed with hygienic standards in mind, featuring a small footprint, and easy-to-clean structure, ensuring the efficient use of space. Applications
