Recently, Advanced Freezers from Netherlands has developed a range of spiral cooler/chillers for the bakery industry: the Advanced Cooling systems. These spiral cooler/chillers obtained a big evaluation and were supposed to represent the ideal bread-cooling concept in terms of hygiene, shelf life and product safety.
Creates an Optimum Environment
To ensure that the products are cooled to a consistently high standard, the advanced spiral cooler creates an optimum environment within the cooling area (insulated enclosure). This includes the use of an air-treatment or air-conditioning unit which maintains a constant level of cooling, irrespective of the weather conditions of temperature either outside the building or inside the production hall, and hence guarantees top-quality products.
Therein, the ideal conditions for obtaining the perfect product after cooling depend on:
First, a constant temperature where the set temperature (between 15 and 25 degrees℃) can be held within the range of plus or minus 1 degrees.
Second, The moisture content (or relative humidity) of the cooling air should be kept within the range of plus or minus 2%. This is crucial to avoid any dehydration or excessive moisturizing of the products.
Third, an air speed that is generated over the products to be cooled should be approximately 1-2 meter per second, depending on their consistency. Advanced Cooling systems use gentle horizontal laminar airflow throughout the entire cooler for a perfect result.
Forth, it is important to create an over pressure within the cooling area to avoid polluted air entering the insulated enclosure through any gaps especially for products with a long shelf life.
Besides, to help reduce the energy costs for the process air, fresh outside air can be partly taken into the circuit as well. However, this must be filtered before entering the cooler, which is why the Advanced Cooling system offers mechanical filters in various formats and filter classifications. Ultraviolet light can also be used to keep the air free of microorganisms.
Designed to Meet Client’s Specific Needs
Also, Advanced Cooling spirals are designed in line with each client’s specific needs, based on the required capacity and retention time. They are available in various belt lengths, as single or double-drum systems, and in any belt width as necessary. Advanced spiral cooler belts are usually made of stainless steel (with or without a mesh overlay) or plastic, and are available in a choice of colors.
Air-Conditioning Units Are Installed Widely
The air-Conditioning Units can not only be installed within the production area, which namely on top of the insulated spiral enclosure, but also can be installed outdoors in which case stainless-steel units are available.
