The cooling process is used to treat fresh or precooked foods. Cooling fresh foods delays the development of bacteria, prolonging the life of the product. In post-cooking processes, cooling is increasingly effective given that the bacteria multiply rapidly at higher temperatures (usually between +20°C and +60°C approximately) and it is therefore indispensable to minimise the time the foods remain within these temperature intervals. An effective process involves cooking foods for a set time and then returning them rapidly to controlled temperatures, thus guaranteeing appropriate hygiene levels and avoiding weight loss due to evaporation.
Some products that commonly undergo the cooling process are bread, pastries, pizza, pasta, poultry, meat, fish, fruit and vegetables.
The conveyor belt is designed to facilitate transport and cooling based on the plant layout, operating conditions and 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.
Spiral cooling towers
Products are cooled inside spiral towers. Spiral towers use all the available vertical space to guarantee the transit of foods inside the cooling unit for the correct 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 be cooled are transported into the cooling units on conveyor belts. The conveyor belts for spiral towers guarantee flexibility in every direction and are therefore suitable for tracks with both straight and curved sections. Costacurta’s conveyor belts are high-quality conveyor belts made of stainless steel. They guarantee maximum hygiene and ease of cleaning.
The distinctive characteristics of the Costacurta conveyor belts for spiral cooling towers:
- Wide range of pitches and turn radii
- High quality welding
- Smooth, uniform surfaces to handle the product correctly
