Abstract: The objective of this study was to evaluate the performance of hydraulic operated tamarind briquetting machine under different moisture levels of tamarind pulp and application of constant pressure at each stroke. The test results indicated a satisfactory working of the prototype. The average density of briquettes varied from 0.94 to 1.07 g/cm3. It was also observed that the tamarind pulp, having moisture content 18.14 to 26.70.% (wb) was suitable for briquetting. It was possible to obtain a final density (1.03 & 1.14 g/cm3) for 500 & 1000 g/cm3of briquette at a constant pressure of 44057 kPa at each stroke. The capacity of prototype of tamarind briquetting machine was found to be 45 number of briquettes per hour for 500 g briquette and 35 number of briquettes per hour for 1 kg briquette. The breakeven point was estimated to be 225 number of briquettes per year for 1 kg briquettes and 392 number of briquettes per year for 500 g briquettes. The payback period is estimated to be 0.31 year for 1 kg briquettes and 0.41 year for 500 g briquettes
