Cooling and Freezing

Cooling and freezing of various products to the highest technical standard. Highest energetic efficiency through the optimal transfer of cold air to the product to be cooled.

When it comes to cooling and freezing, alco offers optimum conditions for achieving high-quality and, at the same time, cost-effective production results thanks to its wide range of linear and spiral systems, which are adapted to customers' wishes. Each machine is calculated, designed and constructed according to customer-specific requirements.

End products could be, for example, sausages, hamburger patties, meat patties, nuggets, schnitzels, cevapcici, meatballs, skewers, veggie products, fish, seafood, packaged ready-made meals, pizzas, baked goods, fruit, vegetables, dairy products, cheese, ice cream or confectionery.

The horizontal air flow and steplessly adjustable fans enable the greatest possible surface area to be cooled or frozen very quickly with extremely high uniformity and efficiency. The product is therefore cooled or frozen in a very gentle and energy-saving way. Furthermore, this ensures first-class structure preservation and reduces weight loss to an absolute minimum, since the system produces no major dehumidification. In addition, extremely short cooling times are achieved through the very efficient cooling process in the IQF (individually quick-frozen) procedure. Uniform air distribution is achieved through horizontal airflow on all levels of the system. Air temperatures and air velocities are kept constant over the entire belt width. As a result, an absolutely uniform cooling of the products is ensured at all points of the system.

Depending on the design, air temperatures as low as - 40°C can be achieved. All common refrigerants can be used. The system is also designed for various defrosting options using circulating air, hot gas, water or electric heaters. Use as a spiral system enables optimal utilisation of the existing local conditions and helps save space needed for other purposes.

All parameters such as belt speed (dwell time), air speed and temperature are set via a PLC control system. All production-relevant data can be delivered directly to the in-house system administrator and control desk at any time or can be viewed or changed by senior operators.

In addition, the highest priority in the system design has been given to hygiene and user-friendliness. The equipment is therefore easy to clean, extremely hygienic and low maintenance due to e.g. directly coupled drives. There are optional automatic cleaning systems for the conveyor belts as well as for the system itself. In addition, only components from suppliers with the highest quality standards are used and installed.
