Freezing converts the water present in foods into ice crystals. This prolongs the life of a food product, maintaining its nutritional and organoleptic values equal to those of a fresh product. During the freezing process, foodstuffs are rapidly brought to low temperatures. Within several minutes they reach a temperature between approximately -30°C and -40°C.
Some products that usually undergo freezing processes are ice cream, pasta, bread, pizza, precooked foods, poultry, meat, fish, fruits and vegetables.
The freezing process usually takes place inside spiral towers or straight tunnels. Spiral towers vertically use all the space necessary to guarantee that foods pass through the inside of the freezing unit for the correct length of time. The spiral towers are usually made as a single or double tower and can be configured in different ways in order to adapt to existing production processes and to the available space.
The foods to be frozen are moved inside the freezing unit on conveyor belts. Conveyor belts for spiral towers guarantee flexibility in every direction and are therefore suitable for carrying out journeys that include both straight and curved sections. Costacurta conveyor belts are high-quality conveyor belts made in stainless steel.
