The developed system inspects and sorts biscuits moving on a conveyor based on dimensions and color (baking level). The measurement of colour and dimensions is useful for quality control of bakery products. Measurement of colour of biscuits is useful in optimum setting of the baking oven parameters. Measurement of dimensions is useful in removing damaged, misshapen and over/ under sized biscuits. A laboratory system has been developed and demonstrated to the stake holders. Similar systems are currently not available in the country. Only a few international suppliers from developed countries are catering to the needs of this industry. The developed technology has got the potential for sorting of other bakery products like buns, square/circular biscuits, etc., with suitable modifications in the hardware and software.
