IQF spiral conveyor

Exceptional Features

  • Freezing variety of products such as shrimp, fish, cake, packaged food...
  • The size is much more compact than the straight conveyor freezing devices, helping to save the maximum installation space with a large belt length, flexibility in construction design.
  • High yield, products keep their original shape after freezing.
  • Consumption of electricity for SAREE's spiral conveyor per product unit is very low, helping to optimize economic profits for investors.
  • It is possible to change the position of the import and export head depending on the requirements of each production area.
  • 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 increase the number of belt layers to meet the capacity according to each customer's requirements.

Description

  • Very long conveyor belt moves spirally in a circular cylinder, the conveyor layers move in a cascade.
  • SAREE's Spiral IQF spiral conveyor is assembled from fully machined and assembled parts at the construction site, saving installation time, the entire frame structure is made of 304 stainless steel to ensure hygiene and food 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 directly connected to the conveyor frame, the frozen product is continuously passed through the cold air chamber by a spiral conveyor rotating around a fixed axis, the freezing speed depends on the size. and product characteristics.
  • 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

  • Spiral IQF shell is assembled Panel panels, inside and outside 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 floors are high density 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.
  • The spiral mesh belt is made from special stainless steel materials, 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, can be placed in humid environments.

Working principle

  • SAREE's Spiral IQF is designed for freezing products with long freezing times and for plants with limited processing space.
  • The product moves from the feeder in a spiral by a spiral conveyor through the freezer chamber by means of a traction motor. In the process of moving the product, it will be directly exposed to the high-speed blowing cold air from the blower. With thousands of jet of deep negative air directly and continuously touching the product on both sides, the thermal layers surrounding the product will be broken allowing cold air to penetrate deep into the center of the product. Therefore, the freezing process takes place quickly. Finally, after moving to the output of the conveyor belt, the products after freezing are separated from the belt by a plastic cutter and sent through the packaging stage.
