Cooling tunnel SPIRAL

The Frigo Impianti Spiral Tunnel is a system designed to be used on medium and large production lines, which enables pasteurising, cooling or deep-freezing of all loose or packaged products that must remain immobile on the belt during processing, for example, hamburgers, pizzas, croissants, ready-made meals, etc. All our tunnels and spirals are designed and built according to the requirements of each individual customer in order to optimise performance and make them adaptable to any productive need. Technical specifications: One of the characteristics of our spirals concerns the ventilated system, which, using a dual evaporator, optimises the system’s refrigerating system and guarantees perfect ventilation inside the room. Handling occurs by means of a central drum that moves the belt, which has already been placed under tension by a motor reducer, when it turns. This system guarantees: • minimum friction; • elimination of any mechanical traction (such as metal gears); • elimination of the continuous use of lubricants in the immediate vicinity of products to be treated. The belt used is a low voltage modulating belt, which has the following characteristics: • made of certified plastic material, which is suitable for the type of treatment to carry out, it enables direct contact with loose and packaged foods; • low friction coefficient, elevated resistance to wear and tear and traction ensure greater reliability and durability over time; • all moving surfaces and other profiles in contact with the belt are made in high-density molecular polyethylene; • the joining hinges, designed for the passage of detergents, guarantee superior levels of sanitation to standard ones
