The company, which has been spending millions of dollars on its expansion drives, recently installed a $50M rice colour sorting machine to help improve the quality of their product.
The Buhler machine was sourced from England.
Known for its Karibee Rice and Pet Rice and other brands, Managing Director, Mohindra Persaud, stated that they decided to invest in the product because they want to up the standard of the product that the company produces.
Persaud stated that they noticed that the grains (paddy) brought from the field are sometimes of a very low quality, thus the quality of the rice will be bad (lot of broken, black rice etc.)
It is not likely to become better.
As such, it was decided to invest in the Buhler machine to improve the quality of the rice produced.
The machine separates the grains according to colour differences in raw rice arising from anomalies like bits of stone, bad rice, black rice, half-husked rice, etc.
A high-resolution CCD optical sensor drives a mechanical sorter to separate different granular materials, automatically sorting heterochromatic particles out of the batch of raw rice; removing such impurities in this process improves the quality of the rice.
Rice mixture travels by elevator belt into a hopper on top of the machine, from which it will flow down along chutes in the colour sorter, streamlining their flow to so that they may be scanned by CCD sensors. The moment the camera detects any colour defects, the camera instructs 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 defected materials from the input rice.
The company is presently constructing a $40M soil-testing lab at the University of Guyana (UG) Berbice Campus.
