INTRODUCTION
We have choose literature review for this assignment.
This literature review about how the tortilla chips are
made.
As example in Malaysia, Kraft Foods Company hasbeen working in this product by the name of chachos
but we focused on the Toms Snacks Company brand
tortilla chips product that located in North Carolina,
USA The reason we focused on this company is because
they used original corn kernels and undergo a process
that turns the maize into the corn dough that called
MASA

From video that we choose for this assignment, we
find the company that produced the tortilla chips.
The company is Toms Snacks Company .
We find the website of the company to know furtherabout this company.

COOKING RAW CORN PROCESS
We observed in the mass production of tortilla chips and
focused on the nixtamalization and masa production
process and highlight at the cooking of raw corn kernels
inside a large cooking kettle with a mixture of a boiling water
and quicklime.
The 300kg of raw corn kernels will be prefilled inside a
hopper valve before it is inserted into the large cooking
kettle that contain almost to 90kg of boiling water

SENSORS
Temperature sensor Thermistor
Thermistor is the best temperature sensor used in the
Hamilton steam kettle considering the environment and the
range temperature suitable for the process of cooking cornAdvantages of Thermistor
Interchangeability
Small size
Rugged, stable, reliable

SENSORS
Weight sensor -Load cell
Specific weight need to be measure for entering the corn in
the kettle tank because the kettle should not be overload.
When the corn inserted into hopper valve 2, the straingauge will stretched and the resistance will increases. Its
explained by diagram below:

SENSORS
Tension Load Cell
This type load cell suitable to measure the raw corn in the
hopper valve 2 by measure the tension from initial position
to actual position after hopper valve 1 enter the HV 2.

ACTUATORS
Pneumatic Actuator For Steam Flow The steam valve is used to control the flow of the steam
from the supply to flow though the jacket around the tank.
This steam is supplied to the jacket as a heat exchangerto heating and control the temperature of the water to
cook the corn in the tank.
It is using a pilot operated control valve to control the
steam for water heating applications.
The pressure is applied to the dome from the upstream
side through the pitot tube.
7/28/2019 Present Cci
13/22
ACTUATORS
The upstream pressure will push the piston to open the
valve while downstream will push the piston downward to
close the valve.
Since it is using a pressure to control the movement of
the piston, the system is using a pneumatic actuator tocontrol the opening and closing of the valve.
7/28/2019 Present Cci
14/22
ACTUATORS
Pneumatic Actuator For Water Inlet Since the product type to be controlled is water, it is
using a quick opening valve to control the flow of the
water. . It is using a fully open and fully closed of the valve plug
to either let or block the flow.
This type of valve allows 90% maximum flow rate and
30% travel of stem. When the pressure is applied, the diaphragm going to
elongate and the spring will push the valve stem.
7/28/2019 Present Cci
15/22
ACTUATORS
The movement of the stem will push the plug from the
seat to let the water flow through the pipe.

ACTUATORS
Hydraulic Actuator Outlet Valve This outlet valve is to transfer the cooked corn to the soft
tank for soak the kernels for 12 hours.
The selection of a correct valve is very importantbecause usually the slurry product will make the products
jam and prevent valve to close.
Therefore, the most suitable valve for the slurry product
is a dome valve. The valve only takes a movement tocompletely open and prevent the jam product since the
plug is a dome shape.
7/28/2019 Present Cci
17/22
ACTUATORS
It is using a hydraulic actuator since the product to
transfer has a very huge weight.
It is also the best actuator selection because it is an
excellent for heat removal since it is a heating process
system.

ACTUATORS
Electromagnetic Actuator There are two hopper valve used in this process that is
Hopper Valve 1 and Hopper Valve 2.
HV 1 use for entering specific amount of raw corn to theHV 2
The most suitable actuator to control this type of valve is
a linear solenoid which is of the electromagnetic actuator.
Solenoids basically consist of an electrical coil woundaround a cylindrical tube with a plunger that is free to
move or slide in and out of the coils body.
7/28/2019 Present Cci
19/22
ACTUATORS
When the current is supplied through the coils windings,
it will cause an electromagnet and the plunger which is
located inside the coil is attracted towards the centre of
the coil.
The spring will push the plunger to close the valve.

CONTROLLER
PLC Controller In this corn cooking process, it better to use PLC
because it is most common due to its ruggedness, ease
of maintenance, price, and safety. Steam jacketed kettle automation process can be easily
handled by the Siemens Braumat package which utilizes
the Simatics PCS 7 DCS.

CONTROLLER
This process using Siemens S7-300 PLC modules that
have advantages that suitable with our process.
Allow quick installation and implementation for common
processes such as heating circuit monitoring without
additional transformer, PID control, synchronous heating,freely configurable controller inputs, and measuring.

RECOMMENDATION
Recommendation for this process is to make
automatically done with the valves of
inserting raw corn, water and the anti-
bacterial into the tank.
The purpose is for safety precaution from hot
temperature of the steam jacket and avoid
the worker approaching the tank.
