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 maching testing exhibited sizing capacity of 1 ton per hour at the efficiency of sizing 89.77% with ignorable mechanical damage. The machine could size mango (Namdoug Mai No.4) into 4 grades (Extra-fruit weight >360 gm., No. 1-fruit weight 310.1 to 360 gm., No.2-fruit weight 250.1 to 310 gm. and No.3-fruit weight 200 to 250 gm.) at belt speed 37.8 cm/sec.
