Spiral freezer are a practical solution for many different food processing applications, as they offer a high level of customizability and can easily be incorporated into your existing production lines. Unlike tunnel freezers, which require long linear wire-mesh belts to convey products through the freezing process, spiral freezers utilize stacked multi-tiered conveyors, reducing the amount of space needed and creating less product loss during transport. Additionally, spiral freezers are much less prone to ice buildup.
Spirals can be used to chill, crust or full freeze a wide variety of foods such as meat & poultry, fish, bakery goods and dairy products. These industrial spiral solutions are ideal for products that have a long residence time, or where there is limited available floor space for equipment.
Compared to other industrial freezers, spirals use a unique combination of high speed fans and evaporator coils that create an intense cold air flow through the product. This system allows the target product temperature to be achieved at a faster rate and with a lower energy consumption than other freezer types. VaCom’s advanced spiral controls work in conjunction with the refrigeration and process equipment control systems to monitor and adjust the spiral parameters based on the specific product that is being processed at any given point in time. This allows the plant staff to quickly and accurately set up a new product, while also ensuring that the entire system is operating at peak efficiency.
In addition to the programmable spiral control, a vacuum pump is also included with every Spiral Freezer. This helps to minimize the moisture content of the product and can help to increase yield. It can also reduce the freezing cycle times, making it possible to reach a higher capacity with a shorter dwell time.
A fully insulated stainless steel frame and fan guards provide protection against moisture infiltration. It is also a very quiet machine, with the maximum noise level being only 70dB. This makes it a good choice for food plants that need to keep their facilities as quiet as possible.
The IQF cryogenic spirals are designed for quick and efficient freezing and chilling of a wide range of products including meat & poultry, fish, baked goods and dairy. These units are also excellent for products with a short residence time or where there is limited available floor space.
A unique high-speed impingement horizontal airflow recirculation system assures each tier of product continuously receives recirculating cold air directly from the evaporator, resulting in fast and efficient freezing, with minimal product weight loss. It also provides the lowest operation cost compared to C02, nitrogen, and other industrial freezers. Its compact packaged design saves valuable process floor space and has an open cage design for easy sanitation and maintenance. Our IQF freezers are fully fabricated and built from reliable components using stainless steel or hot-dipped galvanized steel. This ensures that they are durable and reliable. It can be configured with multiple tiers, inlet and outlet orientation arrangements, as well as various belt widths and designs to meet any application.
