Abstract:
Due to the current environmental
pollution crisis a food packaging industry always
looking for environmental friendly methods for
their use. The process of making poly lactic acid
from lactic acid is achieved more and more
attraction because it is considered to be the most
demanded bio-degradable food packaging film
rather than petroleum based polymer like
polythene. This research is focused to make an
instrumentation to enhance this process while
reducing the instrumentation cost also. The
device has been developed using Atmel general
purpose microcontroller and few semiconductor
sensors. The controlling of the device would be
carried out automatically and date will be sent
to a PC for further analysis.
