Since they’re produced and bottled in a continuous process, adding a tunnel pasteurizer to the production line to manage a constant line of product makes sense. Tunnel pasteurization can be an effective way to handle mass-produced beverages. When to use tunnel pasteurization of carbonated beverages Tunnel pasteurization has its advantages, but to be truly effective, it needs to be used properly. Using Tunnel Pasteurization In Your Facility

The result is a more reliable pasteurization process that can withstand continuous flows of packaged carbonated beverages. Sudden changes in temperature can affect these materials in destructive ways, causing glass to shatter and aluminum cans to burst, especially when there’s heated product inside.īy handling the pasteurization process gradually, these types of packaging don’t have to endure the kind of temperature shock that they might go through in other processes, such as flash pasteurization. Preserves packagingĪnother advantage of tunnel pasteurization is that it can be used on products that are in fragile packaging, such as glass bottles or aluminum cans. To ensure they remain fresh, pasteurization is an absolute must. They may sit on shelves for weeks or months, endure lengthy travel, and may spend some time in a refrigerator or cupboard after purchase. Prolonging the shelf life of these beverages is vital since there may be a long period between production and final consumption by the consumer. This is especially important in beverages such as sodas which have high amounts of sugar. Pasteurization extends the shelf life of carbonated beverages by removing microbes that cause them to ferment or deteriorate in other ways. Tunnel pasteurization prevents that from happening by eliminating those microbes.

In addition to being safe for certain levels of carbonation, tunnel pasteurization can be helpful when it comes to preventing over-carbonation.įor instance, some microorganisms found in beer may produce excess CO2, causing the beverage to burst out upon opening. While there are limits on how much the process can handle, it does offer an advantage over methods that don’t allow for it at all. Tunnel pasteurization, on the other hand, enables certain amounts of CO2 to be present in the beverage. Some pasteurization methods, such as hot filling, don’t allow for CO2 to be added to the beverage since it causes too much foaming during the process. Compatibilityįirst off, tunnel pasteurization is compatible with most carbonated beverages. Tunnel pasteurization offers numerous benefits to breweries, food processing facilities, and anyone else who produces carbonated beverages. Advantages Of Tunnel Pasteurization For Carbonated Beverages Palletization and shipmentĪfter the product is brought back down to room temperature, it’s ready for labeling, boxing, and palletization. The entire concept is incremental temperature changes instead of bringing the product up to the top temperature in one blast. CooldownĪfter reaching the maximum temperature desired, the product is gradually brought down to room temperature. After that, it’s conveyed to the next stage, where the temperature is brought up a bit higher, held in place, and so on until it reaches the maximum desired temperature. In each stage, the product and container are brought to a target temperature and held there long enough to kill off specific microorganisms. The bottled or canned product passes into the tunnel through one end, and throughout the tunnel, its temperature is raised with sprays of hot water. Tunnel pasteurization is unlike other pasteurization processes in that it gradually treats products in a continuous flow from one end of the system to the other rather than shooting for a single target temperature in one go. The advantages that tunnel pasteurization of carbonated beverages offers food processing companies, breweries, and other industries stem from the way its process works. Tunnel pasteurization is one way to handle this process, and it can be particularly effective for carbonated beverages. Pasteurizing beverages helps extend their shelf life while making sure they’re safe for consumption once they hit the shelves.
