In the context of increasingly fierce competition in the beverage industry, manufacturers are constantly pursuing more efficient production modes and greater production flexibility. Especially for the juice beverage industry, the high cost of traditional blowing filling capping combiblock for hot filling, as well as the limitation of only being suitable for high-temperature filling, pose significant challenges to manufacturers. In contrast, ultra clean filling machines stand out with their significant advantages, not only solving the above-mentioned problems, but also bringing more possibilities to manufacturers.
The main advantages of ultra clean filling machine compared to traditional hot filling are:
1.Filling flexibility
Ultra clean filling technology can meet the filling needs under normal, medium, and high temperature conditions, suitable for a wide range of product types such as soda water, mineral water, flavored yogurt, acidic dairy beverages, cold chain products, functional beverages, etc., and is compatible with various bottle types such as PET bottles, HDPE bottles, and PP bottles. On the contrary, traditional hot filling production lines are limited to filling juice, tea, and functional beverages in high-temperature environments, and mainly target PET bottles.
2.Beverage taste and nutrition maintenance
The ultra clean filling using UHT instant sterilization technology can ensure food safety while controlling the temperature at about 68 degrees for filling, thus maximizing the preservation of the original flavor and nutritional value of the beverage. During the hot filling process, the material needs to undergo a long period of high-temperature treatment (from 88 degrees to 40 degrees), which may not only damage the taste of the beverage, but also lead to the loss of some nutrients and increase energy consumption.
3.Production efficiency and cost-effectiveness
Taking the 24000 bph 500ml production line as an example, the ultra-clean system only requires a 12 cavity bottle blowing machine, and the weight of the preform is about 28-30 grams; Hot filling requires a larger scale 16 cavity bottle blowing machine and heavier preforms (36-38 grams). This means that ultra clean solutions can greatly reduce overall costs.
4.The safety and efficiency of sterilization methods
The ultra clean filling machine provides a more reliable and safe disinfection method for bottles and bottle caps, avoiding the common bottle pouring sterilization step in hot filling and directly entering the spray sterilization process, shortening the entire process time and reducing steam usage, further reducing energy consumption and equipment investment.
In summary, the ultra clean medium temperature blowing and spinning system is gradually becoming the future trend of the industry due to its higher cost-effectiveness, wide applicability, and support for multiple product lines.
