How we handle the rice after it is harvested
Wet paddy->dry paddy->storage ->husking->milling->polishing->color sorting ->packaging->logistic->table
Drier
Reduce the moisture content,prevent the wet paddy from getting rotten
Silo
Air conditioned Silos.Keep the dry paddy in low
temperature
(15 ℃),prevent the rice from aging,insects,…etc
Husking Machine
Remove the paddy husk->Brown rice
Milling Machine
Remove the rice bran-
>White rice
Polishing
Make the rice shining and clean on the surface
Color Sorter
Remove the bad kernels such as: yellow kernels,red
kernels,damaged kernles,chalky kernels…
Color Sorter
PackagingPack the rice in different sizes & types(vaccum or non-vaccum)
LogisticMake deliveries
Table
Let’s enjoy!

Traditional way to dry paddy under sunshine
Drawbacks of traditional way• Not possible during rain or at night. Delays in drying lead to
moldy grain and yellow kernels <Losses happen>• Difficult to control temperature.If the sunshine is too
strong,overheating of grains can result in cracked grains.When we mill the rice,the broken kernel percentage
will be high. <Losses happen> * According to our experience,the cracked kernels could be up
to 50% if the paddy is not dried properly under sunshine
Advantages of driers• Stable temperature -avoid overheating • No delay if the weather is bad -avoid delay• The cracked kernels could be reduced to below 10% by using driers
* The heat is provided from burning husk,the cost is lower than diesel.Energy saving.
Storage
Problems warehouses generally have
• Rice bugs
• Rats&birds
• Flood,typhoon,….etc
Rice bugs
Grow fast --30 and 65~70% humidity℃
(the rice bugs could appear in 20~30days)
<Losses happen>
Rats&birds
They like rice,usually they live in the warehouse
Sanitary problem
<Losses happen>
Flood,typhoon,….etc
• Weather pattern is changing
and unpredictable,some
warehouses could only
provide weak protection <Losses happen>
Storage is important
Silos
• Air conditioned,15 inside the silo throughout the year℃ (rice bugs hardly grow at the temperature 15 ~18 )℃ ℃• Strong protection,difficult to get in by water,animals…• Keep the rice fresh,rice is aging very slowly at 15 ,℃ when rice gets old,the color becomes yellow
• Technologies & facilities could help us reduce food losses during production,but the most
important thing is that we need to be aware food will not be enough if we don’t cherish the food
