Product Description

Our spiral freezers are designed based on our many years of experience in freezing and manufacturing techniques.  The complete spiral freezer will be preassembled at the factory and disassembled in sections for shipping purposes; therefore it can quickly reassemble at the job site.  Our simple and practical spiral freezer design with robust construction will provide many years trouble free operation.                    The following are some of our special features and Benefits:
Counter-flow airflow – hottest  products with  warmest Air;  coldest products  with coolest air – maintain and maximize △T between products and the air – the most efficient heat transfer for food freezing. • Air flow arrangement to provide horizontal air flow for better heat transfer for all surfaces of the product. Optimum airflows effectively transfer heat away from your product.
• Coil liquid supply tubes to be regulated by orifices to equalize pressures on each tube, therefore, maximize heat transfer with minimum liquid charge .Vertical Coil – industrial aluminum  tube with aluminum fin.   Hygienic  Design :
• All SS304 weld spiral frame and structures – eliminates hidden cleavages for Bacteria at product zone and provides ease of wash down.
• Freezer structure frames, tier carriers, spiral cage, air baffles and shafts are made of Stainless.  All constructions are for maximum sanitation and long life.
• Pre-manufactured  with  all  SS304 weld  floor  modules  with  slope for  ease  of wash down and drainage.
• High-efficiency fans and motors, evaporators with large face areas, and the spiral conveying system are designed to reduce pressure drop.
• Customized Design : these innovative features provide a spiral freezing system to efficiently handle a wide range of production capacities designed to meet your specific needs.
• Robust and reliable for long life and low maintenance.
• Modular design for easy and quick on site installation.
