|dc.description.abstract||Recently, the demand for natural products has increased, this leads to companies to develop
and have more efficient processes; which is achieved through progressive automation of the
crucial elements of production. In the case of the sponsoring company's project was begun
by the process of pasteurization, one of which must be carried out with greater precision and
Automated pasteurization and is used by most developed dairy companies, but the challenge
was to do it with the lowest possible cost; this meant not only to find the cheapest components
that met the requirements, in addition to reuse the materials, components and existing
devices, adapting to the new system.
However, in order to adapt to an electronic system mechanical elements had to make several
changes; as replacing devices with temperature measurement thermocouples compatible with
the existing pipe connections. Also, take the motor starters and instead of a button, using the
activation of a coil, which by means of an electric drive and an interlock, keep feeding pumps
until the end of the process or disable an operator by a risk.
Subsequently, a measurement system in real time is developed by an HMI display and storage
of data in an external memory; for further review of the process and records required by the
companies responsible for selling the product, performing regular audits.
Finally, it allowed provided inputs and outputs for the other sections of the production
process in order to automate it completely in the near future, goal set at the beginning by the
owner; however because of time it will be left for later stages.||es
