Rice color sorting machine also named Rice optical sorting machine,
it is according to the color differences of granular materials in
raw rice: like stone,bad rice,black rice, half husked rice etc.
using high-resolution CCD optical sensor to separate different
granular materials, automatic sorting heterochromatic particles out
of rice raw materials, so as to removal of impurities and enhance
the quality of rice
Rice optical sorting machine working principle
First of all, the rice is milled in the milling plant, taken
through the paddy boiling unit, drier, destoner, husker, huller
/sheller and then the produced final rice is taken to the color
sorter machine. In this stage, the mixture raw rice will go into
the hopper on top of the machine by elevator and then the rice will
flow down along the chutes of colour sorter. Chutes of colour
sorting machine will make rice flow streamlined for scanning by CCD
sensors in scanning area, The moment the camera detects any color
defects, the camera instructs the ejectors fitted in the machine to
open the nozzle. The nozzle is connected to valves containing
compressed air. This air is then used to shoot out the color
defected material from the input rice. The types of defects in rice
are: black tipped chalky, yellow, mouse droppings, immature grain,
Our advanced technology :
1,Advanced LED optical design system with thermal dissipation.High
brightness,steady temperature LED lighting.
2,Front and rear optical system with high-resolution RGB full color
cameras.Original imported sensor with pixel 5400 elements.
3,Customized shape and size sorting for different materials,
4,Control and adjustment of the defect size
5,Targeting location algorithm
According to different material characteristics,it provides
accurate calculation to material center,which can achieve a hundred
percent sorting and increase the production substantially.
6,Program setting and adjustment are performed through a
user–friendly software which allows the acquisition of the product
image to easily establish the defective elements to sort out.
7,Super large capacity processing chip:scan speed is greater than
30000 times/sec and the overall performance of the system is
increased by 3 times.
8,High-frequency solenoid valve:reduces carryover ratio with
working life over 8 billion blow times.
9,304 stainless steel for hoppers.
10,Anodized aluminum for the chutes.
11,Automatic cleaning system of the optical boxes.
12,International famous brand components to get excellent sorting
performance and long-term running stability.
