Technical Specification of Re-freezer conveyor
Outstanding Technical Specification of Tan Long Re-freezer conveyor
+ Ultra-fast re-freezer for a wide range of products including value-added items and breaded goods on the same conveyor.
+ High freezing capacity, low weight loss ratio after re-freeze
+ Energy-saving due to optimized design, maximizing freezing capacity per unit of energy consumption along with the ability to balance the pressure inside and outside the freezing chamber to minimize cold air loss.
+ Continuous operation time, no need to stop production to defrost the belt and evaporator for up to 23 hours, and can run up to 48 hours without stopping the conveyor for evaporator defrosting.
+ Conveyor belt specifically designed for freezing using stainless steel with extremely high heat transfer coefficient, manufactured in the EU.
+ Easy cleaning of all internal and external conveyor components. Complete drainage after cleaning.
+ The design ensures adherence to HACCP/FDA standards for food hygiene and safety, with high durability, stable operation, and pleasing aesthetics.
+ The safety control system is user-friendly and tailored for food processing environments, offering high stability and accuracy. It is ready to connect to all communication networks within the SCADA system.
Operating Principle of Re-freezer
Products are continuously moved through the thawing chamber on a mesh conveyor specifically designed for food processing. Through the air distribution system, high-pressure cold air streams are blown directly and continuously onto both the top and bottom surfaces of the product. These cold air streams circulate at high speed, continuously breaking the thermal layers around the product. This allows the cold air streams to directly contact and penetrate deeply into the product. As a result, the product thawing process occurs very quickly, preserving cell structure, reducing water loss, and saving operating energy.
Insulated Re-freezer Chamber Panels
The wall and ceiling panels are insulated with 125mm thick polyurethane, density 40-42kg/m3, sprayed by high-pressure machines.
+ Wall panel: Inner surface covered with 0.6mm thick SUS 304 stainless steel, outer surface covered with 0.8mm thick SUS 304 stainless steel with scratch-resistant adhesive tape.
+ Ceiling panel: Inner surface covered with 0.6mm thick SUS 304 stainless steel, outer surface covered with 0.6mm thick SUS 304 stainless steel with scratch-resistant adhesive tape.
+ Floor panel: Inner surface covered with 1.2mm thick SUS 304 stainless steel, outer surface covered with 0.6mm thick SUS 304 stainless steel, cast and welded, waterproof. Re-freezer floor is inclined to ensure complete water drainage during cleaning.
+ The doors are designed for cleaning, maintenance, and repairs.
The doors are insulated with 125mm thick polyurethane, with a density of 40-42kg/m3. Both sides of the doors are covered with 0.8mm thick Inox SUS 304, with scratch-resistant adhesive tape. The locks and hinges of the doors are made of either Inox SUS 304 or plastic. The doors are equipped with silicone seals for tight closure, heating resistance to prevent snow buildup, and locks with mechanisms to prevent accidental locking from inside.
Re-freezer Conveyor Belt
Uses a specialized mesh conveyor belt for seafood processing, made of stainless steel with high heat transfer coefficient, meeting the strictest food safety standards.
Evaporator
The evaporator uses heat exchange tubes made of stainless steel or copper and aluminum fins, depending on the refrigeration system. The technical specifications of the evaporator are calculated and selected to ensure optimal heat exchange efficiency, continuous operation for a long time, and energy cost savings. The evaporator equipment is supplied by reputable suppliers such as Guntner, Thermofin, Kelvion (EU).
Evaporator fan
The fan is made of aluminum alloy, high efficiency, low energy consumption, supplied by Ziehl-Abegg or Rosenberg from Germany.
The fan motor is specially designed for IQF, with IP56 standard for complete insulation and moisture resistance. The motor casing is coated with a special protective layer to ensure durability in low-temperature environments. Motors are provided by ABB or WEG.
Control cabinet
The control cabinet is made of anti-corrosion stainless steel, with moisture and water resistance functions. Equipment and components are sourced from famous brands from the EU, USA, or Japan such as Rockwell, Schneider, Siemens ABB, and Mitsubishi.
