Freezing converts the water present in foods into ice crystals. This prolongs the life of a food product, maintaining the same nutritional and organoleptic properties as the fresh product. During the freezing process, foodstuffs are rapidly brought to low temperatures. They reach a temperature of between approximately -30°C and -40°C in just a few minutes. Costacurta’s products are typically used in different types of freezing systems. The most common foods are ice cream, pasta, bread, pizza, precooked foods, poultry, meat, fish, fruits and vegetables.
The conveyor belt is designed to facilitate the transport and freezing of the food, based on the plant lay-out, the operating conditions and the characteristics of the product to freeze.
The conveyor belts are made of high quality materials, guarantee full hygiene and are easy to clean.
As well as guaranteeing a high-quality product, Costacurta provides technicians and engineers to assist clients in the selection of the belt and in its installation.

Straight tunnels for freezing

Food can be frozen in continuous tunnels at temperatures of between approximately -30°C and -40°C, depending on the freezing process and the product to be frozen. The products are moved on metal conveyor belts inside these continuous tunnels.
The conveyor belt moves the product that is exposed to a jet of very cold air or coolants that rapidly transform the water contained in the foods into ice.

The distinctive characteristics of the Costacurta conveyor belts for freezing tunnels are:

  • Perfect straightness
  • Perfect balance between spirals or shaped flat bars and connecting rods
  • Wide range of mesh available
  • Smooth and uniform surfaces to handle the product correctly

Spiral towers for freezing

The freezing process generally takes place inside spiral towers. Spiral towers use all the necessary vertical space to guarantee that the products remain in the freezing unit for the necessary length of time. Spiral towers are usually single or double and can have different set-ups to adapt to existing production processes and to the available space.

The foods to freeze are moved inside freezing units on a conveyor belt that rotates helicoidally around a central drum. The product is frozen while moving inside the tower.

The distinctive characteristics of the Costacurta conveyor belts for spiral towers are:

  • Wide range of pitches and turn radii
  • High quality welding
  • Smooth and uniform surfaces to handle the product correctly
