Abstract

Development of mango sizing machine is based upon linear relationship between projected area and weight of mango. The machine comprises a portable TV camera taking a picture of moving mango by the control of the photocell. The picture will be scanned, white – pixel counted and compared with the number of white pixel of the standard size mango by 32 bit 68008. Then, it will give signal to a solinoid mounted on the conveyor to tap the mango into the corresponding rotary bin Sizing machine testing exhibited sizing capacity of 1 ton per hour at the sizing efficiency of 89.77% with ignorable mechanical damage. The machine could size mango (Namdog Mai No.4) into 4 classes (extra fruit weight>360 g., No. 1 fruit weight 310.1 to 360 g., No. 2 fruit weight 250.1 to 310 g., and No. fruit weight 200 to 250 g) at belt speed 37.8 cm/sec.
