The composition of hot filling: PET bottle hot filling machine is one of the main equipments in the beverage production line. It is composed of rinsing, filling and capping three-in-one monoblock. It is also equipped with material return tank and circulation system. The equipment structure is compact. It has the advantages of small size and occupied area; the rinsing and filling parts do not need to be connected by the conveyor belt, and transmitted by the star wheel.
The hot filling principle of beverage production line: The composition of PET bottle hot filling material is different from that of ordinary water or carbonated beverage material, and the filling method and filling process are also different. Therefore, the structure of the hot filling machine is quite different from that of the ordinary filling machine in terms of filling cylinders, filling valves and management systems.
1. Because the ingredients of hot filling materials are different, in order to ensure long shelf life and stable quality of the beverage, high temperature filling is required, and the temperature is usually around 88 °C.
At the same time, the internal structure of the filling cylinder is required to be smooth, easy to clean, no CIP cleaning dead angle, and the parts of the beverage production line and the material are all 304 high-quality stainless steel, and the inner and outer surfaces are smooth.
2. The hot filling machine of beverage production line adopts the filling method of gravity
filling and negative pressure reflow. After UHT ultra-high temperature sterilization, the material is sent to the upper cylinder of the filling machine through the conveying pump to maintain a certain head drop of the PET bottle to be filled. The material is filled into the PET bottle through the pipeline above the filling valve and the filling valve.
3. Requirements for high liquid level in PET bottles after filling. The hot filling of the beverage production line requires a higher liquid level or full bottle after the PET bottle is filled, so as to reduce the influence of the oxygen content in the residual air of the bottle mouth on the quality of the beverage. At the same time, the hot air in the bottle mouth material can also replace the air, which is beneficial to the sterilizing of the bottle neck and the inner surface of the bottle cap in the later process of bottle tilting, further to ensure the quality of the juice beverage.
