Flat IQF super speed conveyor

Exceptional Features

  • Freezing variety of products such as fillet fish, butterfly fish, clam meat and some products that require high aesthetics...
  • The freezing time is short, the product quality is uniformly high, there is no cold burn, the frozen product retains its original shape, and the weight loss is low.
  • The cost of electricity consumed for SAREE's IQF conveyor belt per product unit is very low, helping to optimize economic profits for Investors.
  • The indoor unit has a specially designed blade to prolong the time between 2 defrosts, minimizing power loss due to heat loss when defrosting.
  • The conveyor belt is designed and manufactured in compliance with HACCP/FDA standards. Easy to clean to ensure food hygiene and safety standards.
  • Diverse freezing capacity, can design capacity according to customer requirements.


  • SAREE's flat plate IQF conveyor belt is assembled from interconnected modules, the whole frame structure is made of 304 stainless steel to ensure food hygiene and safety.
  • The conveyor frame is placed on inclined surfaces to ensure no water stagnation during the cleaning process.
  • The entire structure is surrounded by insulated panels assembled together to form a closed room, ensuring no heat loss to the outside and wasting energy.
  • The conveyor frame is placed in the middle of the freezer room with large and airy aisles to make it easy to manipulate during cleaning.
  • The feed inlet is connected directly to the conveyor frame, frozen products are continuously passed through the wind chamber containing cold air by the conveyor belt, the freezing speed depends on the size and nature of each product.
  • The control cabinet is located right at the conveyor belt to make it easy to operate, the cabinet is equipped with a PLC controller with an HMI interface. The control interface integrates the input product selection function to automatically control the parameters of conveyor speed, fan speed, chamber temperature suitable for each type of frozen product and can be fine-tuned during operation. motion.

Technical details

  • IQF shell is assembled Panel panels, inside and outside are covered with 304 stainless steel, inside is Polyurethane (PU) insulation with appropriate density to ensure insulation when the conveyor belt is operating at deep negative temperatures.
  • IQF floor is assembled by high density molded PU foam panels with bearing capacity, the top surface is welded with a layer of waterproof 304 stainless steel to protect the insulation board.
  • The entire belt support frame, bearing system, traction shaft, drive shaft, cover, freezer door of IQF are made of 304 stainless steel.
  • Belt plate is made from special stainless steel material, imported from the US, Japan...
  • The indoor unit has 304 stainless steel pipe and frame, epoxy coated aluminum heat exchanger, specially designed for SAREE conveyor belt, imported from Europe.
  • The belt traction motors, indoor fan motors are specially designed, watertight and operate in a temperature environment (-45oC).
  • IQF conveyor belts are fabricated and assembled according to each Module, which is convenient for transportation and complete assembly at the construction site.
  • The control cabinet is made of 304 stainless steel with watertight seals, which can be placed in wet environments.

Working principle

  • After the product is stowed on the feeder belt according to the preset pattern, the product will be moved through the freezing chamber by the belt pulling motor located at the outlet of the conveyor belt. During the product movement, the product will be directly exposed to cold air blowing at high speed from the upper fans through the air distribution hoppers inside the freezer chamber. With thousands of deep negative air jets in direct and continuous contact with the upper surface of the product and the lower surface of the highly conductive sheet belt, the thermal layers surrounding the product will be broken allowing cold air to penetrate. product center. Therefore, the freezing process takes place quickly. Finally, after moving to the outlet of the conveyor belt, the products after freezing are separated from the belt surface by a plastic cutter and sent to the stage of glazing or packaging.
