Though BIS has not put any restriction
on manual filling, humid Indian conditions makes the product susceptible to external
contamination due to unhygienic conditions. Therefore, automation in post processing
stage is strongly recommended. Monoblock machines, capable to rinse, fill &
cap covered in one single enclosure is recommended as this ensures quick packing
hence less chances of contamination through air.
Monoblock machines offer small footprints and
quick transport distance between filling and closing for highly
secured production. As they outperform functions that normally
require employment of several other machines, Monoblock machines
are effectively crafted with modular designs that efficiently
help to change over to different functions, product sizes
and shapes. The frequency converter helps to control the production
The complete parts coming in contact
with water i.e. pipelines nozzles and tanks should have stainless steel construction.
The caps enclosure too, should have disinfecting arrangement (UV) to avoid contamination
arising out of improper disinfecting of caps at early stages.
PET has static charge, it attracts lot of contaminants from the atmosphere and
thorough rinsing is required. As jet rinsing ensures proper cleaning of PET bottles,
the risk of external contamination is minimized. These machines reduce the chance
of product contamination by capping containers as soon as they are filled. Direct
transfer also reduces the chances of spilling. This speeds up entire process giving
the consumer absolutely pure water.
