To meet different customer requirements
Its configuration is highly customizable
But the essence remains the same
Today, let's take a look at
Small combined rice milling equipment
The rice milling process starts with our elevator
The elevator is mainly used to transport our materials
The rice enters the cleaning part of our equipment through the elevator
Which is the cleaning and destoning combination machine
This cleaning equipment features a rotary double-layer screen
The top layer removes large debris like straw and stalks
The bottom layer removes small debris and dust
The cleaned rice then enters the destoning section
Specifically, the gravity destoner
The destoner relies mainly on airflow adjustment
According to different densities
To separate heavier materials in the rice
Such as stones and rocks
Our cleaning process is thus completed
Next is the huller for dehusking
The huller mainly relies on two rubber rollers
With pressure applied by the pressing head
To squeeze the rice between the two rollers
Achieving the purpose of dehusking
Then through the husk separator
To separate the husks
Obtaining what we commonly call brown rice
The hulling efficiency is not 100%
But it can reach at least 85%
The brown rice then enters the gravity paddy separator through an elevator
The function of the gravity separator
Is to separate brown rice from the unhusked rice
Unhusked rice goes back to the huller
Brown rice goes directly to the rice whitener
The main function of the rice whitener
Is to remove the bran layer from the surface of brown rice
Turning brown rice into white rice
The rice whitener can be divided into sand roller whitener and iron roller whitener
The sand roller uses the sharp edges of carborundum
To remove the surface layer of the rice grain
While the iron roller whitens by friction
Between the rice grains and the whitening components
And among the rice grains themselves
Thus, the iron roller whitener applies greater pressure
According to the process of multi-machine light whitening
For different types of rice, Different combinations are used
Normally, Japonica rice can use a combination of sand and iron rollers, such as one sand and one iron, or two sand and one iron
Indica rice, being slender
Can break under too much pressure
So it’s not suitable
For iron roller combinations
It’s better to use two or three sand rollers
Some fans asked about having both Indica and Japonica rice
How to configure then?
In such cases
We can choose two sand and one iron, or three sand and one iron
Or three sand and two iron, etc.
After the whitening process
The rice has turned into white rice
At this stage
We only need to add a white rice grader
And the whole process is completed
However, for small rice mills or cooperatives that need market sales
The black and yellow grains in the rice need further removal
Therefore, a rice color sorter is needed
The color sorter uses the optical properties of the rice
And photoelectric technology
To separate black and yellow
