Hot filling means filling in hot temperature. After the liquid such as juice, milk, tea, coffee is instantaneously sterilized by UHT, the temperature is cooled to 85-92°C for filling. At the same time, the beverage needs to be refluxed to maintain a constant filling temperature which sterilizes bottles and caps. For bottles and caps, there are crystalline heat-resistant PET bottles (capable of withstanding 85℃-92℃ high temperature without deformation) and special heat-resistant bottle cap. Keep the beverage at high temperature for a long time and add preservatives.
The filling system adopts external circulation method and requires CIP. After filling, need to invert the bottle sterilization chain and spray cooling equipment. The machine is equipped with perfect temperature control system, reverse-flow system, automatic cleaning system and control program. Each machine element that contacts with the liquid is made of high quality stainless steel and food-grade rubber.
