Sterilization temperature requirements for spray tunnel sterilizer

The spray tunnel sterilizer is designed on the basis of absorbing foreign prototypes. It adopts circulating warm water preheating, circulating hot water sterilization, circulating warm water to be cold, and then cooling water spray cooling, four-stage treatment form, with sterilization temperature automatic Control, sterilization time frequency conversion and other advantages, can be widely used in a variety of bottled, canned acid juice drinks, electrolyte drinks, alcohol, spices and other products sterilization and cooling. The equipment can be designed according to the sterilization conditions and production requirements put forward by the user.

The spray tunnel sterilization machine strictly monitors the sterilization temperature according to the production sterilization temperature requirements of different varieties. The outlet temperature of the unit cooling section requires: fresh milk temperature: ≤ 6 ° C, fermented milk temperature: 42 + 2-2 ° C. At the end of the production of each variety, pay attention to the liquid level of the material in the material balance barrel, and never let the material empty during the production process. When processing a variety quickly, pay attention to the change of liquid level in the material balance barrel. When the liquid level in the balance barrel drops to about 4cm high position, turn the status switch to the return position, then lower the homogenizer pressure to zero position, close Feed valve. Turn the status switch to the delivery position and start the water top milk: fresh milk time: 2'40", fermented milk 6'30"; then turn the status switch to the return position and close the finished tank feed valve. If the production is finished, the cooling process is notified to stop the ice water. When producing different varieties, pay attention to cleaning pipelines and equipment to prevent product odor.

The spray tunnel sterilizer is specially designed for aseptic packaging equipment for various liquid beverages such as milk, soy milk, peanut milk and juice. It is suitable for various types of aseptic packaging, especially for the production of neutral beverages such as dairy products. It can be stored at room temperature for several months.

Spray tunnel sterilization machine features:

1. Material and heating medium are heated by non-contact heat exchange in their respective sealing systems to ensure the material is safe and safe.

2. Short sterilization time ensures that the nutrients of the materials are not destroyed.

3. The spray tunnel sterilization machine adopts food grade stainless steel materials to ensure the safety and health requirements of the national beverage and food equipment.

4. The sterilization machine has good heat transfer effect, high heat recovery rate and low energy consumption.

5. The main control components, valve parts and matching parts are all imported parts, which have long service life.

6. The tubular UHT adopts PLC control, which can automatically control the heating temperature, hot water temperature and steam flow adjustment of each section of the material, and has an automatic material returning system to ensure that the material reaches 100% sterilization effect.

7. The spray tunnel sterilization machine has simple structure, easy cleaning, convenient operation and low maintenance cost.

The spray tunnel sterilization machine mainly completes the whole process through the conveyor chain system, the bottle reverse chain system, the frame and the bottle flipping bar, without any pollution to the bottle, the frequency conversion control, the transmission chain speed can be adjusted, and the whole process is safe and reliable. Pay attention to the following during the operation of the spray tunnel sterilization machine:

Check the homogenizer status according to the “Homogeneity Machine Operation Procedures” to ensure that the material pipeline is unblocked. Turn on the power and compressed air, start the material pump and hot water pump, let the water cycle for 3~5 minutes, check whether the unit is running normally, and there is abnormal situation. If you can't make adjustments, you should report the equipment maintenance personnel on time. After the standby group is running normally, open the steam valve to allow the unit to circulate and heat, and ensure that the plate cooling section outlet temperature is above 85 °C for at least 15 minutes. Check the disinfection of the finished tank, determine the tank order according to the production plan for the day, and check the opening and closing status of each valve. After the product of the batching process is qualified, homogenization and sterilization shall be started according to the production schedule of the day.
