Custard apple is a dryland fruit crop and grows well with less water requirement and adverse climatic conditions. The production of custard apple is increasing in India. The main constraint in custard apple processing is deseeding of pulp. Hence, there is demand for small size machine which can separate pulp and seed from custard apple. Therefore, deseeding machine for custard apple pup was developed which was consist of a brush roller, cylindrical sieve, discharge chutes, cover with feed hopper, a rigid base supporting the frame and transmission unit. In order to evaluate the performance of the machine, experiment was conducted at roller speed (215, 227 and 257 RPM), feeding rate (0.2, 0.3, 0.42 and 0.6) and three cylindrical sieve (1,2 and 3). Cylinder 2 with inlet diameter of 213 mm and outlet diameter of 177mm shows better results with machine efficiency 82.50 % and minimum pulp loss of 2.09 % among three cylinders. It was observed that machine capacity and machine efficiency increased with increase in roller speed and feeding rate.
