Abstract:
Raw mangoes in India are mostly used for making pickles and chutneys. Mechanical operation of slicing and cube cutting of raw mango is advantageous because of more precise slicing and cube cutting than manual cutting. It reduces fruit damage and improves efficiency and accuracy. A power operated raw mango cutting machine designed and developed for small scale processing industry based on physical and engineering properties of raw mangos. The machine is consist of main frame, primary cutting blade, feeding hopper, holding shaft, cutting blades, upper trough plate, bottom trough plate and power transmission unit. The performance evaluation of raw mango cutting machine was conducted for the four different speeds of holding shaft i.e., 27, 32, 37 and 42 rpm. The results observed best at speed of 32 rpm having cutting capacity 111.8 kg/h, cutting efficiency 82.92% and damage percentage 17.11%.
