Because carbonated soft drink usually adopts low-temperature (4-10℃) filling, but ambient temperature of workshop is much higher, so it is very easy to condensed dew on bottle surface which will bring trouble to the downstream as labeling. Especially, if using carton packing, the dew will make carton wet to cause serious damage. Therefore, after the filling machine, It is necessary to use a bottle warmer to heat the bottle to the ambient temperature. The warmer is tunnel type showering equipment which heats the bottle through spraying hot water for heat exchange. It usually has 3 temperature zones( more zones are possible). After heated by section, the bottle’s temperature could achieve ambient temperature, usually design for 30-35 ℃.  Bottle warmer is mainly composed of machine base, conveying chain, transmission system, water storage flume, recycle pump, showering device, heating device and pipes. Exchanger could adopt steam plate type exchanger and electrical type exchanger.
