From Digital Truck Scale, trucks will proceed to a parking
lot for rice sampling. Our staff will take samples to inspect
for any pseudo-mix. The sampling is performed in both physical
test and chemical test. The physical test begins with taking
samples from each truck and putting them forward to length
and size comparison, and moisture measurement. Data are collected
and recorded for a statistic of each origin, Regarding the
chemical test. Uthai Produce Co., Ltd. owns an advanced laboratory
and rice inspection facility, which are equipped to perform
examination precisely and accurately To start with, rice samples
are to be put into a divider in which they will be intermixed
and sorted into batches for the next 5 inspections. Whitening
inspection by Whitening Meter indicates whiteness of rice
grains in percentage. Cooking inspection is carried out by
preparing rice samples of 100 grains per batch and cooking
them for 16 minutes, then, mashing them on a test plate. Jasmine
rice will be well cooked but other kinds of white rice will
have brittle remains. Alcohol dyeing Is the next inspection
whereby rice samples are soaked in alcohol, rinsed clean,
and then soaked in color dye. Dyeing process takes about 5
minutes. Other kinds of white rice will turn more purple than
jasmine rice. Amelose test and spectrophotometer process begins
with grinding rice samples into powder, taking specific amount
by weight and mixing them with prepared chemical in a magnetic
shaker. Then iodine is added before examining with a spectrophotometer
to find if an amelose percentage matches the company�s requirement.
Besides these is Alkali Test, which needs soaking of rice
samples in potassium hydroxide for 23 hours. Jasmine rice
will disperse into powder but other kinds of white rice will
stay in the same condition. Data are then collected for statistic
background.

Only rice hat passed the above 4 tests are transported to
the Intake. Staffs are dressed securely and a podium is presence
to avoid any physical contacts with the rice. Rice must go
through preliminary cleaning before storing in a silo.
Rice is transported by Belt Conveyer to be stored
in a silo. Processing begins with cleaning by magnetic separator,
which will remove all metal debris such as nails and wires
from the rice.

In Pre Cleaner stage, larger remains such as strings are removed.
Next, a Fine Cleaner stage, which the final cleaning is executed
by Bag Filter to vacuum dust and other small particles from
rice grain.Next, the Destoner will remove splinters in the
rice by using siphon principle. Rice grain will be drawn up
by strong air suction to let splinters fall off by gravity.

Cleaned rice will proceed to whitening and polishing process.
Whitening Machine will whiten rice grain then a Polishing
Machine will polish rice grain for a desirable look. Processed
rice will now go through sifting process. Starting at Rotary
Sifter, which will separate rice into Head Rice, Mixed Rice,
and Big Broken Rice.
The Mixed Rice portion is put into Indent Cylinder to be re-separated
into Head Rice, Big Broken Rice, Medium Broken Rice, and Small
Broken Rice. When different type of rice is obtained, rice
is then blended together in an according ratio to export regulation.
Next is color inspection by a Color Sorter, which implements
advanced technology using 2 sets of Photo CCD Sensor to detect
rice passing through a camera. A camera begins transmitting
signal to detect any rice grain different in color from a
standard. Detection will activate air blower, which will blow
out defected rice grain into
bad rice vent. Standardized rice will be kept in containers
for further packing. All production process at Uthai Produce
Co., Ltd. are automated and controlled by advanced, computerized
Interlock system, which enable all machineries full time automation.

Besides production process, packing is as equally important,
which has made products from Uthai Produce Co., Ltd. accepted
worldwide. Packing is done in both semi-automatics, which
employs labors in putting on sacks, and full automatic. Both
are highly accurate and are controlled by digital weighting
machine. Weight is rechecked while on conveying belt by Weight
Checker, which checks the final weight to sort out over- or
under- weighted pack immediately. More over, during loading,
each and every pack must go through metal detection for any
metal item inside a pack by a Metal Detector. We will make
a test by putting metal item on a pack. When the pack passes
through a Metal Detector, it will be detected and sorted out
as well. Loading rice packs onto a truck by conveying belt
is observed by an Automatic Counting Machine, which has a
sensor to link with the whole loading system. The truck itself
must also go through inspection. A container is checked before
loading and is insecticide after loading is completed to prevent
from moth and other insects. You can be confident of all rice
products departing from our company are of a quality and a
quantity by your order.
