PET Bottle Aseptic Cold Filling Production Line
Products scope: suitable for packing acid and neutral liquid products, including
products with with a diameter of 3-5mm granules in the ultra-clean
and aseptic filling condition.
Such as milk, yoghurt, dairy liquid products, plant protein
beverage, flavor beverage, juice, coffee, tea and other drinking.
Technical characteristics of aseptic cold filling:
1). There’s an air sucking and curtain device in the inlet of
bottles to separate the air between inside and outside of machine.
It will effectively prevent inner irritating gas leaking and
outside air pollution going inside.
2). It adopts liquid channel sealing structure in each rotating
part. Prevent bearings and other transmission parts from corrosion
of disinfectant liquid and gas.
3). It adopts automatic centralized lubrication system. The
frequency, time and volume of lubrication can be set up freely in
the touched screen.
4). It adopts or equivalent brand motor in the transmission system.
5). It adopts non-contacting filling way to prevent secondary
pollution. It adopts high precision electrical flow meter in
filling valve to control the filling volume.
6). Electrical flow meter and electric control system are installed
outside of aseptic room. Better for user to observe and
maintenance. Reduce the space of aseptic room.
7). There is a CIP cleaning fake cup in the filling valve. CIP
cleaning process will be done by PLC automatically.
8). It adopts American rotating joint sealings with features of
reliable effect and low failure rate. It adopts running sterile
water or clean steam barrier protection mode between sterile air
channel and sterile material channel to prevent from cross
contamination.
9). It adopts on-line spraying way to sterilize in the bottle
outlet conveying chain.
10). There are gratings and fluid bath sealing protection devices
in all water discharging pipes. They can prevent water-discharging
pipes from sundries blockage. Outside air also couldn’t enter into
aseptic room.
11). Aseptic isolation system, foam cleaning system and
disinfectant spraying and fumigating system are optional in machine
working environment.
12). It adopts stainless steel 304 to make the main electric
control cabinet.
13). Production speed, shift production count, trouble shooting
category, trouble shooting point and others will display on the
touched screen. Flow meter parameter set-up and correction also can
be done on the touched screen. It’s very easy for user to operate.
