Professional Flash-Freezing Technology, Making Food Better
Dejieli liquid nitrogen rapid freezing equipment achieves an extreme low temperature of -196°C. When pre-frozen products come into contact with the ultra-low temperature rapid freezing equipment, they rapidly vaporize, instantly removing heat from the product surface through thermal exchange. Within seconds, the product traverses the ice crystal growth zone, forming uniformly distributed microcrystals throughout the frozen food structure. This instantly locks in moisture with virtually no loss, preserving the food's original color, flavor, texture, and shape.
Dejieli's quick-freezing equipment utilizes ultra-low-temperature anti-icing fans. This design not only effectively prevents vibration and noise caused by fan blade imbalance due to frost buildup but also ensures smooth and efficient blade operation. This achieves energy-saving and environmentally friendly objectives.
The patented high-efficiency cold transfer system and airflow field design employ specialized ultra-low-temperature insulation materials to lock in cold energy. Compared to similar products, this design reduces energy consumption by 30%.
Highly efficient and stable CIP cleaning system featuring a graphical user interface display. Automatically switches between process parameters and adjusts cleaning duration, temperature, and other settings. All operations are fully recorded to facilitate GMP certification. The tunnel-type quick-freezer employs a lift-up design for easy daily maintenance and inspection of product residues. This effectively prevents potential cross-contamination between products, ensuring strict adherence to food safety standards.
Dejie Li quick-freezing equipment features a programmable logic controller (PLC) with an intuitive human-machine interface for simple and convenient operation. It supports preset production modes, allowing seamless switching between different product processes while ensuring consistent batch-to-batch consistency. The tunnel-type quick-freezer employs a modular vertical lift design for high flexibility, enabling easy configuration adjustments based on production capacity needs. This design also facilitates maintenance and servicing.
