Tomato sorting according optical properties for its maturity stages [electronic resource].

In the current paper, automatic control unit for tomato sorting according to their color based on using two control factors (feeding speed and sensor height) under steady air velocity with different peifonnance evaluation parameters (sorting efficiency, productivity, energy requirement and operation cost with two varieties tomato (Bito 86 and Zaina Rs 692). The results showed that, the feeding speed at the range fr<?m 0.10 to 0.15 m/s gave the height value of sorting efficiency from 97.48 to 96.18% with productivity from 80.70 to 94.80bkglh at sensor height of 35 mmm for Bito 86. Also, the height value of sorting efficiency from 96.74 to 96.38% with productivity from 57.90 to 67.80 kglh respectively at sensor height of 30mm for Zaina Rs 692.Relating to the effect of feeding speed on energy requirement, the obtained data showed that, increasing feeding speed from 0.10 to 0.225 mls, the energy requirement decreased from 3.83 to 3.97 and 5.35 to 4.25 kfY.hlton for Bito 86 and Zaina Rs 692 respectively. The operation cost of sorting machine depended mainly on the sorting productivity, required power and number of workers. Refering to the effect of the previous factors operation cost equal 5.66 L.Eih
