Cold Filling vs. Hot Filling for Beverage Production
Cold filling vs hot filling for beverage production, when you want to produce juice or similar drink, you need know the differences between them clearly. So let us discuss about them:
1. The first machine difference is how to sterilize.
For the hot filling system, the hot filling material is the main force for sterilizing. First, the UHT sterilizing system sterilize the material with hot temperature. Then the temperature come down to 85℃-92℃. After the machine fill the material into the bottle, the material is hot still. Then the hot material will sterilize to the bottle and inside. For the cold filling, it is different. The UHT sterilization sterilize the filling material also, then the temperature will come down to the normal temperature. The bottle washing system sterilize to the bottle, and the cap washing system sterilize to the cap. Then the laminar flow hood will sterilize to the air. So the cold filling machine sterilization is separate.
2. The bottle is different.
For the hot filling system, the PET bottle need to be thick to resist the hot material. And the bottle need more reinforcing ribs for same reason. Finally the bottle mouth have to crystal to resist the high temperature. For the cold filling, the bottle is normal bottle is ok. So the bottle cost different will be much.
3. The suitable beverage is different.
For the hot filling system, the high-acid beverage, like tea drink, juice drink and sport drink are more suitable for hot filling. For the cold filling system, the beverage need high flavor and nutrition are more suitable. And the cold filling system cost is high, so the big scale beverage production is more suitable for it, because the big quantity low cost bottle can make the average cost per bottle come down. for the middle and small scale beverage production, the hot filling system is more economic.
So that is the main differences between cold filling and hot filling, if you have any questions, you can let us know!
