- Abstract
A medium-sized blackberry pulp extractor was designed and built so that blackberry juice could be made quickly, hygienically, and commercially. The machine was designed based on the principle of compression and shear due to the action of screen cylinder and wing shaft as well as evaluated various performance indicators such as throughput of the pulp extractor, juice yield, extraction efficiency, and extraction loss. It consists of a strong frame, hopper, screen cylinder, wing shaft, prime mover, and power transmission devices with the main shaft. The data obtained from the design analysis of the components were used in the sizing, fabrication, and assembling of the machine. The throughput of the pulp extractor, pulp yield, extraction efficiency, and extraction loss were 39.58 ± 0.29 kg h-1, 77.49% ± 1.18%, 96.72% ± 1.06% and 6.38% ± 0.5% respectively. Therefore, the invented blackberry pulp extractor would be recommended for commercial blackberry fruit juice producers.
