 Abstract

Manual determination of weight and size of papaya is a difficult and labour intensive element of the commercial fresh fruit market. To overcome this problem, a prototype machine was developed for determination of weight and size of papaya. Load cell made of four strain gauges in a Wheatstone bridge configuration was used to determine fruit weight and size. The evaluation results showed that the prototype machine was capable of weighing and sorting the fruits into different sizes (i.e. large, medium and small) with average accuracies of 94.7% and 86.6% respectively.
