Spraying Type Pasteurization and Cooling Tunnel, also known as Tunnel Pasteurization Machine, is a common automatic pasteurization equipment in food and beverage factories. It achieves product safety, extends shelf life, and maintains taste through multi zone spray heating and cooling. Whether used as a beer pasteurizer, juice sterilizer, or bottle and can sterilization tunnel, the correct equipment selection can help companies improve production efficiency, reduce energy consumption, and maintain stable product quality.
1.production capacity
Capacity is the primary consideration factor. Small craft breweries may only require compact beer pasteurizers, while high-speed juice or carbonated beverage production lines require large multi zone food sterilization tunnels. It is necessary to match the length of the tunnel and the number of spray areas based on production capacity (such as 10000-60000 bottles/hour) to ensure that each bottle can achieve the required sterilization unit (PU).
2.container type
The tunnel must mDifferent packaging forms have different requirements for tunnel design:
PET bottles need to be slowly heated and cooled to avoid deformation.
Glass bottles are more heat-resistant, but they are prone to breakage due to excessive temperature differences.
Can → High strength, but requires uniform heating to ensure product consistency.
Choosing suitable beverage sterilization equipment design can effectively reduce the rate of damage and defective products.
3.Sterilization index and cooling curve
Beer and juice typically require 12-20 PU. High quality spray pasteurization cooling tunnels can achieve target PU through precise zone temperature control, while avoiding taste loss caused by excessive sterilization. A smooth transition in the cooling zone is equally important to prevent container damage or flavor loss.
4.Energy and water resource utilization efficiency
Traditional tunnels have high water and energy consumption. The modern energy-saving tunnel pasteurizer is equipped with a heat recovery and water circulation system, which can reduce energy consumption by about 30% and significantly reduce operating costs.
5.Automation and Control Systems
Advanced tunnel equipment is usually equipped with PLC/HMI control, online temperature sensors, and remote monitoring functions. Automated control can reduce manual errors and improve stability, which is an important feature of modern automatic pasteurization equipment.
6.Equipment size and production line layout
The tunnel must meet the space requirements of the factory and be able to seamlessly connect with transportation, filling, packaging and other processes. A well-designed sterilization tunnel for bottles and cans can avoid bottlenecks in the production line and improve overall efficiency.
Uneven temperature → Multi zone spray system ensures that each bottle of product meets the standard PU.
Excessive energy consumption → Water circulation and heat recovery systems can significantly reduce energy consumption.
Damaged bottles and cans → Thermal shock can be reduced through preheating and slow cooling zones.
Complex cleaning and maintenance → Modular design and automatic CIP cleaning system can shorten downtime.
When choosing a tunnel pasteurizer supplier, attention should be paid to:
Experience and Cases → Do you have successful project experience in beer, juice, dairy products, etc.
Customization capability - Can personalized solutions be provided based on production capacity, containers, and factory layout.
After sales service - whether to provide installation and debugging, operation training, and spare parts supply.
Certification and Compliance → Whether it complies with international certifications such as CE, FDA, and local food safety standard.
