摘要
This invention relates with the development of a machine called COMMERCIAL SCALE STEP WISE EXPANDING PITCH FRUIT GRADER that can be is used for grading of different spherical fruits having equivalent diameter of 30 mm to 145 mm. The principle involved is sizing through one-dimensional separation of fruits by carrying the fruits on an expanding pitch flap conveyor. The main components of the fruit grader are grading unit, horizontal belt conveyor and elevator feeding unit. The grading unit consists of 19 mm pitch hollow pin chain and matching sprockets, steel flaps and rollers, wheel track, collection tray, power source, reduction gear unit, power transmission system and fruit collection tray etc, fruit-loading/feeding unit is ergonomically designed. The horizontal moving belt is provided to eliminate impact damage during feeding of constant and uniform quantity of fruits to the grading system. The grader has the provision to separate fruits into five grades by adjusting flap spacing between 30 to 145 mm. Testing of the fruit grader showed overall grading efficiency of 97 % for citrus fruits. The capacity of the grader was 5 t/h at grading conveyor speed of 7 m/minute and there was no damage to the fruits while grading. The cost of the grader is Rs. 70,000 and only 1 hp motor has been used to operate the grader. The advantages of this fruit grader are high level of versatility, high capacity, low energy consumption, low cost, minimal handling and tumbling of the fruit and there is no damage to the fruit while grading. The cost of operation of grader was found to be Rs. 1000 per tonne. The fruit grader reduces the energy and cost by 45-50% and 60-70%, respectively with grading efficiency of 97% in comparable to other available grader having grading capacity of 5t/h. This development is highly beneficial for industrial applications.
