Tea beverage is usually used to hot filling and cold aseptic filling two kinds of method, due to many limitations, domestic enterprises is used in former times. The processing of fruit juice, tea beverage technological requirements strictly, from PET bottle filling technology production technology, production technology and production line operation, beverage quality the comprehensive comparison, selection of hot filling technology is more economical and reliable.

Hot filling requirements of fruit juice, tea beverage by UHT instantaneous ultra-high temperature sterilization after maintained at85℃~95 ℃between a fixed value, and in a very short time . At the end, belong to the high temperature filling. General carbonated drink, filling is positioned or quantitative material type, there is always a certain distance from the bottle mouth. And fruit juice, tea beverage, especially the production quality of the original flavor drinks, requirements of full mouth filling material, which has been filled into the bottle mouth, so that the residual air in the bottle is few, can ensure the beverage itself is not easy to be oxidized, so as to make the beverage long-term to maintain its quality. Due to the hot filling with high temperature filling, mouth filling function, which requires the coordination of automatic circulation system, convenient for low temperature material circulation heating and CIP circulation cleaning.

Heat-resistant PET bottle in hot filling, biaxially stretched PET heat shrinkage, shrinkage rate is generally 1% to 3%, and the bottleneck area of maximum strength, which requires the card filling bottle mouth positioning method is most reasonable, to avoid the bottle body by external force deformation. At the same time, filling good drinks, the card bottle conveying, the bottle body can not subjected to vibration and extrusion material overflow. Mouth filling. Currently used thermal Filling Machine    method has two kinds, one kind is similar to the Italy TECH-ITAL character Si He PROCO MAC model, the filling valve of the liquid inlet channel and a return passage is opened, closed step by step;

Another kind is similar to Taiwan ‘s machine, filling valve of the liquid inlet channel and a return passage is opened simultaneously, closed. We in the full digestion and absorption of foreign technology developed on the basis of the unique design of hot filling valve. Filling valve material filling mouth two, in the most part, so the valve core head takes up little space at the bottle mouth, filling, the filling valve is inserted into the mouth, filling at the end of the filling valve, a liquid inlet channel and flow channel is a step-by-step and sequentially closed, valve away from the bottle, the volume occupied by, by return passage within the beverage to supplement the perfusion, thus can ensure that the beverage bottle is full fill, filling. Similarly, we need to reduce the filling valve adjusting gasket also can realize liquid level filling.

In recent years, Wine Filling Machine and Juice Hot Filling Machine development is very swift and violent, almost a year to double the speed of increase.
